Generators

Ofgem's interim CEO confirms the regulator will publish its ED3 strategic decision tomorrow (21 May 2026), signalling a 'targeted' rather than anticipatory build-out: invest where demand growth is clear, lean on flexibility elsewhere. Jarvis confirms electricity transmission expenditure could reach around £70bn over five years, that the connections queue has been cut by 220 GW from 700+ GW via NESO triage, and that Ofgem will progress a Debt Relief Scheme writing off up to £400m of crisis-era domestic debt. He also flags consultation this summer on house-moves rules (where roughly a third of supplier debt accrues) and a shift toward outcomes-based retail regulation under a PACT framing (Predictable, Agile, Collaborative, Technology-enabled).

CMP477 proposes a CUSC change to allow a single connection modification request to span more than one Transmission Owner area, rather than forcing developers to raise separate applications when their works touch the boundary between TO networks. Raised by Andrew Urquhart on 19 May 2026 as an Urgent modification under an Authority-agreed timetable, status Proposal Raised. NESO classifies the impact as Medium across generators, demand customers, TOs (including CATOs) and consumers.

DESNZ announces £15.6m through the Heat Network Efficiency Scheme to upgrade 94 existing heat networks in England and Wales, plus £25m through the Green Heat Network Fund for four new projects including Bristol City Leap expansion and a sewer-heat scheme in Rochdale. Funding sits within the previously announced Warm Homes Plan envelope (£195m/yr GHNF, £15m/yr HNES to 2029/30).

DESNZ pre-announces the Energy Trends and Prices release covering March to May 2027, the monthly statistical bundle on production, trade, generation, consumption and retail prices for coal, electricity, gas and oil. This is the regular series, not a methodology change or new dataset. Content itself is not yet published; this is the scheduling notice.

DESNZ has directed under section 35 of the Planning Act 2008 that National Gas Transmission's Project Union: East Coast hydrogen pipeline be treated as a Nationally Significant Infrastructure Project requiring a Development Consent Order. The Project covers up to 420 km of new mainline hydrogen pipeline plus ~200 km of repurposed NTS pipe across Teesside, the Humber and the East Midlands, with 13 Hub Above-Ground Installations at locations from Bishop Auckland to Staythorpe. The direction was needed because the pipeline narrowly fails the s.20 NSIP threshold (under 50,000 customers), so DCO consent would otherwise not apply.

NESO has raised GC0186, a Grid Code modification updating restoration requirements following GC0156's implementation of the Electricity System Restoration Standard. The proposal introduces Regional Restoration Plans, equal treatment of NGET, SPT and SHET during restoration, requirements for Network Operators to switch at sufficient speed, and tightened testing and data obligations. Currently at Workgroup Nominations stage, governance route still to be decided by the Panel.

Ofgem has issued procedural guidance to electricity suppliers and generators with Renewable and Electricity Register accounts on how to hold REGOs for GB Fuel Mix Disclosure 2026. The letters set out the administrative process for the 2026 FMD cycle; they do not change the underlying REGO scheme rules, eligibility, or trading mechanics.

Ofgem has been appointed administrator of the government's Bill Discount Scheme, which gives households living near new electricity transmission infrastructure up to £250 per year off their bills. DESNZ aims to lay regulations in Summer 2026, with first payments in early 2027. Ofgem will consult on delivery mechanics (eligibility, compliance) for six weeks from July 2026.

Ofgem has been named scheme administrator for DESNZ's bill discount scheme, which pays households living near new or significantly upgraded electricity transmission infrastructure up to £250 per year for up to 10 years. This is an administrative appointment; the scheme itself, sitting alongside Community Funds, was already established as a community benefit package for transmission hosts. No change to the scheme parameters, eligibility, or funding mechanism.

The Secretary of State has used Energy Act 2023 section 245(1)(a) and (e) powers to insert new Standard Licence Condition 11C into the Electricity Supply Licence and a new Schedule 35 into the Retail Energy Code, mandating that electricity suppliers expose tariff and export-tariff pricing data via a standardised API. The licence condition takes legal effect on 18 February 2027; suppliers must build a compliant Tariff Interoperability API, register a Supplier Endpoint with RECCo by 31 December 2026, and meet 99.9% monthly availability with a 95th-percentile 1-second response time at steady-state volume. Smaller non-domestic-only suppliers below 100,000 meter points are exempt, as are block tariffs, current-transformer-metered sites, and bespoke charges.

Three University of Sheffield Key Knowledge Deliverables from the £1bn Net Zero Innovation Portfolio CCUS Innovation 2.0 programme, comparing a novel molten carbonate fuel cell (MCFC) approach to BECCS against conventional amine post-combustion capture, plus solvent performance data for MEA versus the CESAR1 (piperazine/AMP) blend. The reports document techno-economic baseline configurations, capture rates (~95% biomass flue gas, up to 100% on the MCFC natural gas feed), and solvent degradation/nitrosamine management. They are status-of-project knowledge documents, explicitly not final and not changing any rule, charge, or business model.

DESNZ has published Key Knowledge Deliverables from Promethean Particles' MONET project, a pilot-scale carbon capture rig using Metal Organic Framework solid sorbents, funded under the £1bn Net Zero Innovation Portfolio CCUS Innovation 2.0 programme. The released documents (D3.3 build and D4.1 installation) are factory and site acceptance test verification sheets for a prototype unit tested on Drax's flue gas stream at its CCUS Incubation Site in May 2025. The substantive deliverables (CAPEX/OPEX technoeconomic analysis, lifecycle assessment) are listed as pending release after redaction.

Muirhall Energy has raised CMP471, a temporary CUSC amendment letting Users adjust connection dates and contract elements before the first CMP434 Gated Application Window and the 1 April 2027 liability trigger. The CUSC Panel unanimously recommended urgent treatment on 15 May 2026; if Ofgem agrees by 19 May, implementation lands 31 July 2026 instead of an undated 2027 slot. Without it, queue holders enter Gate 2 carrying contractual connection dates that no longer match deliverable programmes.

NESO proposes a defined process for commissioning and funding pathfinder feasibility studies under the network services pathfinder programmes. The modification (PM0133) creates a standardised mechanism between the System Operator and Transmission Owners for scoping and procuring feasibility work, with Panel Approval as the governance route. Status remains Proposal Raised; no decision date set.

NESO has reissued STCP 11-1 (Outage Planning) as Issue 013, incorporating System Access Reform changes and a revised Emergency Return to Service (ERTS) profiling regime under modification PM0153. The procedure governs how the system operator and transmission owners (NGET, SPT, SHETL, offshore TOs, and Competitively Appointed Transmission Owners) coordinate outages from six years ahead down to day-ahead handover. The substantive change is to ERTS profiling; the rest is administrative consolidation of CATO inclusion already made in Issues 011 and 012.

NESO has raised PM0153 to revisit the criteria for recalling transmission circuits with longer Emergency Return to Service (ERTS) times during winter. The modification mandates use of a Winter Risk Policy Form to document system margins, constraints, mitigations, and recall plans, with the aim of clearing more winter outages without breaching security standards. It is self-assessed as low impact on Transmission Owners, Transmission Licensees, Generators, and System Operators, with a Panel Decision governance route.

DESNZ has refreshed its index page for local-authority and community decarbonisation support, listing existing programmes: the £19m Local Net Zero Accelerator (three pilots), the Local Net Zero Hubs, the £10m Mayoral Renewables Scheme, and the £5m Great British Energy Community Fund (continuing the 2023-25 Community Energy Fund on the same scope and eligibility). It appends a register of CEF and GBECF awards, almost all £10k-£100k grants for community solar, hydro, heat networks and feasibility studies. No new money, no rule change, no change to how generation connects or what it is paid.

Ofgem proposes to allow Liverpool Bay CCS Ltd to recover costs from a Change in Scope Re-opener under its CCS transport and storage economic licence, covering the ongoing Runcorn TCPA planning application and the licensee's participation in the Cubico Frodsham Solar Project DCO examination. The submission follows DESNZ's deprioritisation of Viridor under the HyNet Track-1 Expansion. Ofgem's minded-to position adjusts the Approved Project Development Plan, Financial Settlement Document and project-specific licence schedule rather than changing the regulated revenue model itself.

The Secretary of State granted a development consent order for North Falls, a ~1 GW offshore wind farm of up to 57 turbines roughly 40km off the East Anglia coast. Consent covers construction, operation, maintenance, and decommissioning under the Planning Act 2008. This clears the principal planning barrier for a project led by North Falls Offshore Wind Farm Limited (an SSE Renewables / RWE joint venture vehicle).

Ofgem has put market participants on notice that withholding interconnector capacity to drive extreme auction prices is non-compliant with the Electricity Regulation prohibition on capacity hoarding. The accompanying paper sets out observations on occasional price spikes in NESO interconnector auctions between 2022 and 2026 and the steps Ofgem expects traders to take to demonstrate compliance. It is a regulatory warning shot rather than a new rule, but it signals enforcement intent against specific bidding behaviour.

The Secretary of State has formally determined the standard licence conditions for code manager licences under Sections 33(1) and 81(2) of the Utilities Act 2000, completing the legal step that brings code manager licences into existence for electricity (s.6(1)(g) Electricity Act 1989) and gas (s.7AC(1) Gas Act 1986). This is the determination instrument enacting the SLCs already finalised in the March 2026 joint government-Ofgem consultation response; it adds no new policy. Code managers will replace the existing self-governance model where industry parties run their own code panels.

DESNZ published the statutory Fuel Mix Disclosure data table for the April 2024 to March 2025 period, the figures suppliers must use on customer bills under supply licence condition 21. The residual fuel mix (the pool allocated to suppliers not buying REGO-backed or sourced electricity) is 74.7% gas, 14.8% coal, 6.3% other, 3.9% nuclear and 0.3% renewables, with a carbon intensity of 919 g/kWh for coal and 382 g/kWh for gas. The headline UK supplied mix including imports is 42.1% renewables, 33.3% gas, 16.2% nuclear and 5.9% coal.

This is a release-date announcement for DESNZ's monthly solar PV deployment statistics, not the statistics themselves. The April 2026 data will be published on 28 May 2026 at 9:30am. No deployment figures, capacity numbers, or trends are contained in this page.

DESNZ proposes a second, higher price cap in the Capacity Market auction to procure new-build dispatchable enduring capacity for prolonged tight-supply periods, plus a package that reduces information given to participants before and during auctions to suppress strategic bidding. Battery CMUs would be allowed to self-nominate connection capacity below full network capacity to avoid degradation-related extended performance test failures, biogenic generation would gain a route to low-carbon CM benefits via sustainability criteria, and a Termination Fee would be introduced for currently fee-free Termination Events with payment suspension for units in Insolvency Termination Events.

DESNZ proposes Capacity Market Rule changes for the July 2026 Prequalification round, the most consequential being a route for CfD-directed Generating Units to keep CM agreements without drawing both subsidies simultaneously, plus tighter delivery assurance: a more stringent termination framework and Credit Cover held until a New Build CMU completes commissioning. It also sets CM eligibility criteria for Long Duration Electricity Storage Cap and Floor projects, clarifies Secondary Trading entrant rules, and adds a higher CapEx threshold to qualify for the second, higher price cap under the Multiple Price Capacity Market. The consultation runs ahead of Prequalification commencing July 2026 and auctions in 2027.

DESNZ is gathering evidence on how to categorise Hydrogen to Power (H2P) plants within the Capacity Market so they can bid as a new technology class, and on revising the technical adjustment used to set interconnector de-rating factors, including how high-impact low-probability events are treated. The de-rating factor directly determines how much capacity an asset can sell, so a methodology change reprices interconnector revenue. Categorisation sets the de-rating treatment and reliability assumptions H2P will be held to before any plant exists.

DESNZ has granted development consent under the Planning Act 2008 for RWE's two Dogger Bank South offshore wind farms, each up to 1.5 GW, for a combined 3 GW across up to 200 turbines. The arrays sit 100 km (West) and 122 km (East) from shore in the North Sea, with onshore export cables and converter stations connecting to the National Grid.

DESNZ and RECCo propose a new obligation in the Electricity Supplier Standard Licence Conditions and the Retail Energy Code requiring every supplier to publish tariff pricing data in a standardised, machine-readable format via a defined API. The arrangements add a TI Arrangements Schedule to the REC, redline the Standard Definition Document, and specify the data items, market messages, and API technical specification that Energy Smart Appliances will read to respond to price signals. Phase one runs through the REC and Supplier SLCs with implementation activities scheduled from post-consultation to early 2027.

Ofgem has endorsed five innovation challenges for the Strategic Innovation Fund covering RIIO-3 transmission (2026-2031) and electricity distribution (2028-2033): six-month industrial connections by 2033, 50% faster and 20% cheaper build by 2035, plug-and-play domestic device connections by 2032, near-zero outages via autonomous islanding by 2038, and decentralised local balancing by 2034. The challenges were recommended by the Energy Networks Innovation Taskforce and will be delivered through Innovation Delivery Groups and SIF-funded projects. This document sets the target framework; it does not allocate funding or change rules.

John Crane UK Limited published the closing documents from its CCUS Innovation 2.0 grant project to develop an uncooled high-temperature dry gas seal for supercritical CO2 power cycles. The work covered new simulations, material compositions, and testing validation aimed at reducing seal leakage and potentially enabling an additional turbine expansion stage. This is a component-level R&D output from a competition-funded project, not a policy or market change.

DESNZ has published the project documents from Immaterial Limited's CCUS Innovation 2.0 grant to develop monolithic metal-organic framework (MOF) adsorbents for post-combustion carbon capture. The work designed a demonstrator to strip CO2 from flue gas using structured MOF adsorbents instead of conventional amine solvents, which suffer from degradation, corrosion, and a high energy penalty. This is a materials R&D output, not a policy or market measure.

Ofgem has directed Ørsted ESS Mersey Limited to surrender its mandatory Elexon share, revoking an earlier direction issued under Standard Licence Condition 21.5 of the Generation Licence. Elexon administers the Balancing and Settlement Code; its shares carry no economic value and exist only to bind code parties into the governance structure. This is a single-licensee administrative tidy-up, typically following a generator exiting the BSC party population or ceasing licensable activity at the relevant site.

DESNZ publishes selected projects awarded funding under the Direct Air Capture and Greenhouse Gas Removal Innovation Programme. Programme supports innovation in negative-emissions technologies.

DESNZ Great British Energy framework document. Sets out the operating framework for the new state-owned energy company GBE.

DESNZ consults on changes to the Contracts for Difference contract to implement Clean Industry Bonus (CIB) reforms ahead of Allocation Round 8. Proposed changes: workforce protection through a Fair Work Charter, skills investment criteria, onshore wind into the CIB for AR9, hybrid metering contract changes, and various process improvements. Tracked amendments published alongside.

DESNZ publishes funded projects under the Hydrogen BECCS (Bioenergy with Carbon Capture and Storage) Innovation Programme. Phase 1 (£5m) funded scoping for 22 organisations; Phase 2 has a £26m budget for innovation design through demonstration. Three categories: feedstock pre-processing, advanced gasification, and novel biohydrogen technologies.

NESO explains its voltage reduction capability, where DNOs cut distribution voltage by 3-6% to reduce demand during emergencies. Testing with DNO groups shows a 3% voltage reduction yields approximately 1.2% demand reduction. Full DNO-wide testing is planned to refine the process.

NESO publishes its forecasting strategy to 2030, committing to probabilistic forecasts, multiple weather data sources, and in-house cloud infrastructure (Platform for Energy Forecasting) to replace legacy systems. The headline number is an estimated £2.5m per month saving from dynamic reserve setting underpinned by probabilistic forecasts, reducing average reserve holding by 400MW. FES2025 anticipates 90-120GW of wind and solar installed capacity by 2030 and 12-16% demand growth from 2024 to 2030.

NESO's Constraint Management Intertrip Service (CMIS) page consolidates the three active constraint management programmes: EC5 East Anglia (enduring service starting mid-2026), B6 Anglo-Scottish boundary (15 generators contracted, now extended to September 2027), and a new CMIS Scotland consultation launched 13 April 2026. These are commercial alternatives to transmission build, paying generators to accept automatic disconnection post-fault so more power can flow on existing infrastructure pre-fault.

Ofgem has rejected CMP344, which sought to shift the cost of offshore transmission Income Adjusting Events (IAEs) from offshore generators to demand consumers via the Transmission Demand Residual. The existing arrangement, where generators bear IAE costs through Offshore Local Charges, remains in place. The modification had been in development since May 2020 and was sent back twice before this final rejection.

GC0164 rewrites Grid Code Operating Code 2 (Operational Planning and Data Provision) in plain English with diagrams and flowcharts, without changing any obligations on users. The Panel unanimously recommended the original proposal. It now awaits Ofgem decision, with implementation 10 business days after approval.

The CUSC Panel on 24 April 2026 progressed three new modifications and one workgroup report. CMP469 creates a one-year cost recovery mechanism for parties affected by Grid Code restoration obligations (GC0186). CMP472 allows NESO to share large embedded generators' red line boundaries with DNOs without customer consent, enabling Gate 2 distribution contract verification. CMP471, which proposed interim contract variations ahead of the first CMP434 gated application window, was sent back to the proposer for scope clarification.

STC modification CM097 mandates Transmission Owners to submit EMT and RMS models of their assets to NESO, enabling system-wide dynamic modelling as inverter-based resources replace synchronous generation. The workgroup unanimously supported the original solution. Implementation aligns with Grid Code modification GC0168.

GC0168 would require legacy generators (completion before 1 September 2022) to provide Electromagnetic Transient models to NESO on request, enabling analysis of inverter instability, system oscillations, and transient overvoltage on a grid increasingly dominated by power electronics. The workgroup's preferred alternative (WAGCM1) defers the obligation for GB Code Users until a CUSC cost recovery mechanism is in place, while applying immediately to EU Code Users. Responses due by 8 June 2026.

DESNZ publishes accounting officer assessments for three major projects: CCUS Track-1 (HyNet and East Coast Cluster), the STEP fusion prototype, and the Boiler Upgrade Scheme extension. All three pass the four standard tests (regularity, propriety, value for money, feasibility). No new funding, no rule changes, no new mechanisms: these are retrospective sign-offs on decisions already taken.

DESNZ has published the process for generators excluded from CfD rounds to apply for exemption from their temporary site exclusion for Allocation Round 8, due to open in July 2026. Exclusion applies to generators that let a previous CfD offer lapse or had a CfD terminated. The notice sets out information requirements, the closing date for exemption requests, and where to submit them.

Ofgem proposes an early competition OFTO build model where transmission assets are competitively tendered before construction, rather than after. The consultation also updates the existing late competition model. Early competition would be mandatory in certain circumstances, with detailed proposals covering tender process, evaluation criteria, and commercial framework.

Ofgem has accepted urgency for CMP470, a CUSC modification proposing a commitment fee for oversubscribed generation technologies in the grid connection queue. Raised by Field Energy Limited on 20 March 2026, the proposal would price queue positions for technologies that dominate the 700 GW backlog. Urgency was requested by the CUSC Panel on 27 March and accepted by Ofgem on 2 April, meaning this bypasses the standard modification timeline.

Ofgem is gathering evidence from gas shippers and interconnectors to assess UNC0903, which would replace the current locational NTS capacity reference prices with a single uniform price across all entry points. Separate RFIs target shippers using interconnectors (IUK/BBL), LNG terminals, and Norwegian pipelines, plus the interconnectors themselves and National Gas Transmission. The modification is subject to an Authority decision; this RFI will feed an impact assessment.

DESNZ lists 23 training providers sharing up to £8 million to deliver subsidised retrofit and solar PV installation courses under the Warm Homes Skills Programme, targeting up to 9,000 training places by July 2026. Courses span Level 2 entry-level retrofit awareness through Level 5 retrofit coordination diplomas, delivered across England's five Net Zero Hub regions.

DESNZ publishes the Q1 2026 extract of the Renewable Energy Planning Database, tracking all UK renewable electricity projects above 150kW through planning, construction, operation, and decommissioning. The database is managed by Barbour ABI and covers project-level detail including capacity, technology type, CfD allocation round, planning status, and grid coordinates. It includes an interactive map and links to the equivalent heat network database.

DESNZ published updated technical guidance for UK ETS installation operators on monitoring and reporting obligations under the 2018 MRR. Covers uncertainty assessments, biomass reporting, data flow controls, and sampling requirements. No rule changes; this is compliance documentation for an existing scheme.

DESNZ lists 25 projects that received £36 million across two phases of the Biomass Feedstocks Innovation Programme, funding R&D in domestic biomass production including algae, miscanthus, hemp, willow coppice, and forestry. Phase 1 awarded £4 million for project development; Phase 2 awarded £32 million for demonstration. Both phases are now closed.

DESNZ published the list of successful projects under its CCUS Innovation 2.0 programme, covering Calls 1 and 2. The programme funds 20+ R&D projects totalling roughly £22m across capture solvents, MOF-based adsorbents, CO2 utilisation in concrete and fertiliser, subsea storage equipment, and reservoir simulation tools. Most projects are TRL 3-7, targeting cost reduction and scale-up for next-generation capture and storage technologies.

DESNZ published project documents from Keadby Generation Limited's FOCUSS project under the CCUS Innovation 2.0 programme, exploring flexible post-combustion carbon capture with solvent storage. The project aimed to de-risk technology allowing CCS plants to operate flexibly rather than baseload-only.

Ofgem has rejected CMP344, which proposed shifting offshore Income Adjusting Event (IAE) costs from generators connected to OFTO assets onto demand consumers via the Transmission Demand Residual charge. The rejection preserves the status quo: generators connected to offshore transmission remain liable for IAE costs on their OFTO assets. This applies to both existing and future OFTOs.

UK solar installations hit 27,000 in March 2026, the highest monthly total since 2012, bringing cumulative installations past 2 million. Solar capacity grew 11.7% year-on-year, adding 2.3 GW. Peak solar output passed 15 GW for the first time on the GB system.

DESNZ quarterly energy statistics for Dec 2025-Feb 2026 show renewables at 51.8% of major power producer generation, gas down 11% year-on-year to 35.5%, and nuclear down 11% to 11.9%. Primary energy consumption fell 3.3% (2.1% temperature-adjusted). Indigenous production fell 4.5%.

UK solar PV reached 22.1 GW across 2,003,000 installations at end of March 2026, up 11.7% (2.3 GW) year-on-year. March 2026 saw 27,607 new installations (121 MW), the highest monthly installation count since 2012. Ground-mount now accounts for roughly 58% of total capacity, with 25 CfD-accredited solar farms operational including 19 commissioned during 2025.

DESNZ commissioned Baringa to update its 2024 assessment of supply chain constraints across renewable and network technologies to 2035. The study identifies bottlenecks that could delay deployment and recommends industry or policy interventions to address them.

The Secretary of State has corrected errors in the Tillbridge Solar Development Consent Order 2025, a large solar project in Lincolnshire. This is an administrative correction to an already-granted DCO, not a new planning decision or policy change.

Ofgem has granted urgency status to CMP475, which would allow NESO to reopen fixed BSUoS tariff periods mid-period when the Working Cash Flow (WCF) threshold is forecast to be exceeded, and to introduce a mechanism to recover the WCF position toward neutral within that period. NESO raised the modification on 15 April 2026; the CUSC Panel unanimously backed urgency on 21 April; Ofgem accepted on 29 April. This changes BSUoS from a truly fixed charge to one that can be reset intra-period, shifting forecast risk back onto demand users.

Ofgem has granted urgency status to CMP474, a CUSC modification that would introduce a reset mechanism for the fixed BSUoS tariff in response to rising balancing cost volatility. NESO raised the proposal on 14 April 2026 and the CUSC Panel unanimously supported urgency on 21 April. Urgency status compresses the modification timeline from months to weeks.

DESNZ has completed its statutory three-year review of the NSTA, concluding the regulator is effective but needs reformed objectives and stronger powers. The NSTA's principal objective will shift from Maximising Economic Recovery to three balanced objectives covering economic value, net zero, and workforce transition. Maximum financial penalties increase from £1 million to £5 million, with power to raise to £10 million; decommissioning cost estimates have risen from £37 billion to £44 billion.

DESNZ has updated its index page for Climate Change Agreement guidance. CCAs give energy-intensive industrial users a discount on the Climate Change Levy in exchange for meeting energy efficiency targets. No new rules or changes are announced; this is a document collection page.

DESNZ has published updated template agreements for the Climate Change Agreements scheme, covering the new phase with target periods from 1 January 2026 to 31 December 2030. CCAs allow energy-intensive industrial operators to receive a discount on the Climate Change Levy in exchange for meeting energy efficiency or carbon reduction targets. The templates set out the contractual framework between the Environment Agency, sector associations, and individual facility operators.

DESNZ and Ofgem published the outcome of a call for evidence on whether the RAB model of economic regulation for CO2 storage should evolve as the CCUS market matures. The call closed 31 October 2025 and explored whether unbundled CO2 storage could support competition, reducing the need for regulated returns and government revenue support agreements. This is part of a four-document series on transitioning CCUS to a self-sustaining market.

DBT publishes updated application guidance for the UK ETS and CPS indirect cost compensation scheme for energy-intensive industries. The scheme compensates 14 eligible sectors (by SIC code) for carbon costs passed through in wholesale electricity prices, using efficiency benchmarks and a 5% GVA intensity test. Key parameters for 2026-27: UK ETS reference price £53.19/tCO2, CPS rate £18/tCO2, CO2 emissions factor 0.45 tCO2/MWh, subsidy intensity capped at 75% of indirect costs or 1.5% of GVA.

DESNZ has announced that the monthly solar PV deployment statistics for August 2026 will be published on 29 September 2026, moved from 24 September to align with the Energy Trends release. No data is contained in this publication; it is a pre-announcement of a future statistical release.

DESNZ has pushed the next solar PV deployment statistics release from 25 June to 30 June 2026, aligning it with the Energy Trends publication. No data is included in this announcement.

The UK Kyoto Protocol Registry closed permanently on 1 April 2026. This is an administrative notice confirming the closure of a legacy carbon accounting system that has had no operational relevance to GB electricity markets since the UK left the EU ETS.

DESNZ will publish Energy Trends and Prices for February 2026 on 30 April 2026 at 09:30. This is the monthly compendium covering production, trade, generation, consumption across all fuels, plus retail and wholesale price indices. This is the pre-release announcement; the data itself is not yet available.

DESNZ will publish monthly Renewables Obligation certificate and generation data for December 2026 on 8 April 2027. This is a pre-announcement of a confirmed statistical release, not the data itself. ROC issuance data tracks the volume and technology mix of generation still operating under the RO scheme.

DESNZ will publish Energy Trends and Prices for February 2027 on 29 April 2027, covering monthly production, trade and consumption across all fuel types plus retail and EU comparative price data. This is a pre-announcement only; no data is yet available. The release is a regular monthly statistical publication.

The Secretary of State has issued corrections to the Rampion 2 Offshore Wind Farm Development Consent Order (1,200 MW). The publication contains only the fact of the correction with no detail on what was changed. This is a routine administrative tidying of an already-granted DCO.

DESNZ has issued ministerial directions under section 52 of the Climate Change Act 2008 covering three UK ETS matters: defining eligible fuels for maritime operators making emissions reduction claims under Schedule 2A paragraph 37, setting penalty levels for installation operators with permits under article 50(4), and penalties for ultra-small emitters exceeding thresholds under article 60(6). The penalty directions have been in force since October 2023; the maritime fuel eligibility direction references EU renewable energy and waste directives as at April 2026. Parallel directions have been issued by devolved governments.

DESNZ has published the document collection page for CfD Allocation Round 8. The page itself contains no substantive policy content, budget parameters, strike prices, or pot structures. It is a navigation index pointing to the CfD microsite, delivery partners, and a bulletin subscription.

DESNZ publishes the UK's first fossil fuel subsidy inventory under its COFFIS commitments, cataloguing every tax relief, rebate, and support measure that reduces the cost of fossil fuel use. The inventory confirms £7 billion of Renewables Obligation costs will shift from consumer levies to exchequer spending over 2026/27-2028/29. It also commits the UK to publishing a national phase-out strategy for fossil fuel incentives by COP31.

DESNZ has published the statutory notices required to launch CfD Allocation Round 8, including a new Clean Industry Bonus (CIB) allocation framework. The CIB is a supplementary payment mechanism layered on top of the standard CfD strike price, rewarding generators that meet domestic supply chain content requirements. These are the formal legal instruments that trigger the round opening.

DESNZ is reviewing Ofgem's mandate, statutory duties, regulatory remit, and enforcement powers. The call for evidence covers whether Ofgem's principal objective should shift from promoting competition to broader goals including innovation and consumer standards, whether its accumulating statutory duties should be streamlined, and whether it should gain FCA-style Consumer Duty and Senior Manager Regime powers. The consultation closed 28 February 2025; outcomes are now being considered.

DESNZ publishes the first comprehensive review of Ofgem in its 25-year history, proposing to rewrite its statutory duties, give it direct consumer law enforcement powers without court action, introduce individual executive accountability, and cap bonuses for rule-breaking. The review will produce a reformed Strategy and Policy Statement to separate government policy-setting from regulatory delivery, and commits to clarifying the boundary between DESNZ, NESO and Ofgem. Ofgem's workforce has grown from 890 FTE in 2014/15 to 2,110 in 2024/25.

Ofgem publishes final determinations on Contracts for Difference disputes raised in 2025. Decisions resolve contested payments between LCCC and generators under the CfD scheme.

DESNZ published the outcome of a call for evidence on how CO2 transport and storage networks should evolve from government-backed RAB models toward commercially self-sustaining operations. The call, which closed 31 October 2025, covered capacity booking reform, network utilisation, flexible products, and the future of Revenue Support Agreements and Government Support Packages for T&S operators. It sits alongside parallel workstreams on CO2 storage economic regulation and non-pipeline transport.

Ofgem's Jack Presley Abbott confirms that the battery pipeline emerging from connections reform may be oversupplied relative to Clean Power 2030 needs, and that many protected 2026 and 2027 projects will miss their original dates. Ofgem is considering intervention to prune the queue, and names demand-connection reform, including a data-centre levy, as the next front.

Miliband speech at the National Growth Debate. Frames the RNP package, SMR contracts, Sizewell C consent and EGL extension as a coherent clean energy security programme.

DESNZ consults on siting and investment levers under Reformed National Pricing (RNP), the programme that replaces REMA after ministers rejected zonal pricing. Closes 2 June 2026. Ofgem runs a parallel Call for Input on network and connections charging to 26 May. Together these set how much new generation and storage pay, and where.

DESNZ has announced a Wholesale Contract for Difference (WCfD) that would let existing Renewables Obligation and merchant generators swap forward wholesale revenue for a fixed government strike price, while ROC income continues unchanged. The Electricity Generator Levy rises from 45 to 55 percent, removing the legislated taper to zero. Consultation on WCfD design comes later in 2026, allocation in 2027. Reformed National Pricing is confirmed as the post-REMA track; zonal is off the table.

The RNP Delivery Plan landing page. Frames the 21 April DESNZ consultation and confirms REMA is closed. Substantive response window is the companion siting-and-investment consultation.

Ofgem and DESNZ confirm 221 GW has been removed from the connection queue under the new Gate 2 / Phase 1 process, with self-selection into Gate 1 filtering out additional capacity. Battery storage has progressed to Gate 2 at a materially higher level than planned: 14.8 GW above the Clean Power 2030 Action Plan range and 61.7 GW above projected 2035 system need. Protection measures for projects with planning consent, Capacity Market agreements or near-term offers, combined with batteries' faster consenting speed, are named as the cause.

DESNZ will publish March 2026 monthly solar PV deployment statistics on 30 April 2026. This is a pre-release announcement confirming the publication date; no data is yet available.

Ofgem calls for stakeholder input on NESO's Business Plan 3 performance for 1 April 2025 to 31 March 2026, the final year of RIIO-2. Assessment moves to a Below/Meets/Exceeds Expectations grading across two components: delivery of business plan aims (via Success Measures) and value for money. Responses due 18 May 2026; final decision summer 2026.

DESNZ and Ofgem signal they may intervene to remove battery storage projects from the reformed connection queue, where 14.8 GW above the Clean Power 2030 Action Plan range and 61.7 GW above projected 2035 system need have progressed to Gate 2. The surplus was caused by protection measures for projects with planning consent or Capacity Market agreements, which batteries secured faster than other technologies. NESO's annual consultation proposes disapplying protections so that only batteries with revenue support schemes qualify for future windows, and a code modification imposing financial attrition measures has been granted urgency.

Ofgem rejected urgency for BSC modification P510, which proposed replacing the mutualised compensation arrangements under P415 with direct compensation for Virtual Trading Party actions in the wholesale market. P510 was raised by Flexitricity on 5 March 2026 after evidence of rising volumes and costs in the P415 mutualised compensation fund. Related urgency requests for P509 and P511 were considered alongside and also rejected.

Ofgem has granted urgency for BSC modification P511, which proposes an eligibility threshold above which generation assets cannot participate in wholesale markets via Virtual Trading Parties (VLPs) created under P415. Raised by Axle Energy on 18 March 2026, P511 responds to a recent increase in the volume and cost of the P415 mutualised compensation fund. This is the third urgent modification (alongside P509 and P510) targeting the same problem: P415's market access framework is generating socialised costs that were not anticipated.

DESNZ will exempt over 10,000 manufacturers from Renewables Obligation, Feed-in Tariff, and Capacity Market levy costs on their electricity bills from April 2027, cutting bills by up to 25% (£35-40/MWh). The scheme expands eligibility by 40% from 7,000 to 10,000 businesses, with a one-off backdated payment covering April 2026 to March 2027, and is expected to cost £600 million per year funded through unspecified 'changes within the energy system' and Exchequer funding.

DESNZ publishes the summary programme business case for Great British Energy - Nuclear's SMR programme. GBE-N received over £2.5 billion capital funding in the 2025 Spending Review for the first project and enabling activities. Wylfa on Anglesey was selected in November 2025 as host site for the first SMR, adding up to 1.5 GW. Funding model undecided but RAB is under consideration. Delivery will run through an operationally independent DevCo intended to attract private investment.

Ofgem has published a call for input on the future regulatory framework for electricity interconnection, covering route to market, competition models, financing structures, and treatment of Offshore Hybrid Assets. This accompanies DESNZ's policy paper on interconnection's role in a strategically planned system. GB currently has 10.3 GW of operational interconnector capacity with 1.4 GW in construction and 8.9 GW in development under existing approvals.

Ofgem is challenging the widespread use of fixed MW thresholds — particularly the 100MW threshold — for determining whether outage and availability information must be published as inside information under REMIT Article 4. The regulator flags that threshold-based approaches ignore prevailing market conditions, cumulative effects of smaller outages, and aggregation across a participant's portfolio. The guidance explicitly extends expectations to Offshore Transmission Owners (OFTOs), signalling that transmission availability disclosure has been inadequate.

Ofgem has rejected IGT165, a modification proposed by OVO Energy to create an Independent Shrinkage Expert and Independent Shrinkage Charge on Independent Gas Transporter networks. The proposal aimed to incentivise reduction of gas shrinkage emissions on IGT networks by introducing a dedicated charge and expert role. Submitted September 2025, the rejection means the existing shrinkage arrangements on IGT networks remain unchanged.

Ofgem has approved NESO's methodology for refreshing the second transitional Centralised Strategic Network Plan (tCSNP2), which will reassess the transmission network build programme needed through the 2030s. The refresh will update cost estimates, delivery timescales, and network designs from the 2024 tCSNP2, incorporating connections reform outcomes and revised offshore network configurations. It also feeds into the pipeline for the full CSNP due by December 2028.

Ofgem has directed NESO to delay the first Centralised Strategic Network Plan by 12 months: submission moves from June 2027 to 15 September 2028, publication from December 2027 to 15 December 2028. The delay aligns CSNP with the revised Strategic Spatial Energy Plan timeline. NESO requested the derogation itself on 23 March 2026, and Ofgem granted it.

Ofgem has conditionally approved NESO's methodology for producing the Centralised Strategic Network Plan (CSNP), the first independent long-term plan covering electricity, gas transmission, and hydrogen transport and storage networks in GB. The methodology uses the Strategic Spatial Energy Plan as an input and describes how NESO will identify system needs, develop options, appraise them, and recommend delivery. Approval is subject to two conditions requiring further detail on unspecified areas.

DESNZ has published the methodology behind its Subsidy Control Transparency Database entries for CfD Allocation Round 7, disclosing that the total estimated subsidy has been rounded to the nearest £5 billion. AR7 contracts are now 20 years (up from 15) for fixed and floating offshore wind, onshore wind, and solar. Estimates use the AR7 Allocation Framework valuation formula and are presented in 2024 prices, undiscounted.

Ofgem republished the template Letter of Authorisation used when opening or updating an account on the Renewable Electricity Register. It is an administrative form, not a rule change.

UKAEA published its 2026-2030 strategy for the national fusion laboratory, setting objectives around completing STEP prototype design, expanding research facilities at Culham, and growing the fusion supply chain. It accompanies UK Fusion Energy Ltd's own strategy and builds on the government's Fusion Strategy launched the previous month.

UKAEA published a Global Fusion Guide for SMEs, a supplier-facing explainer on how UK businesses can enter the global fusion supply chain. It claims over 68 private fusion companies are operating and cites £100bn of expected global fusion spend between 2026 and 2035. No rules, charges, or market structures change.

UKAEA publishes its 2026-2030 strategy for the National Fusion Laboratory, setting out research priorities alongside UK Fusion Energy Ltd (renamed from UKIFS in March 2026). The strategy confirms the £2.5bn fusion RDI budget to 2030 and four themes: International, Research, Commercialisation, Industry. Operational focus on H3AT, LIBRTI, MAST-U and JET decommissioning.

NESO has published Issue 8 of the EDL Message Interface Specification, the protocol Balancing Service Providers use to receive dispatch instructions and submit dynamic parameters. The update implements Grid Code modification GC0166, adding two new submission message types: Maximum Delivery Offer (MDO) and Maximum Delivery Bid (MDB), plus decimal-place precision for MWh values. References to BOAR and Replacement Reserve have been removed.

NESO's index page listing electrical standards documents for transmission-connected generators across England, Wales, SPT and SHE Transmission areas. The page was refreshed to show an updated EDL Message Interface Specification dated 13 April 2026; all other listed standards are unchanged.

DESNZ has updated the UK ETS free allocation table following Activity Level Change adjustments, with the 2021-2025 allocation period extended to cover 2026. The table sets installation-level free allowances for energy-intensive industry and, notably, some power-sector CHP and gas compressor stations. Several 2026 allocations step up materially (Tate & Lyle to 70,578 from 40,824; Humber Energy to 38,725 from 28,092) while others (CF Fertilisers Billingham) stay flat at 150,426 after earlier cuts.

DESNZ updated the UK ETS Aviation Allocation Table for the 2021-2025 period to reflect operator transfers and cessations. The table lists free allowance entitlements for aircraft operators; 2023-2025 figures remain indicative pending the free allocation review.

DESNZ has published a revised Electricity Supply Emergency Code setting out how rota disconnections would be imposed during a prolonged electricity shortage. Non-protected demand is split into 18 Load Blocks of ~5% each, disconnected in three-hour rotations under NESO-issued Activation Schedules, with Protected Sites shielded via a four-tier list (Tier 0 energy infrastructure, Tier 1 hospitals, Tier 2 essential services, Tier 3 industrial sites facing >=10% asset damage). The update follows a 2023 review and reflects the split between the short-notice Demand Control Rotation Protocol and the prolonged-emergency ESEC route.

DESNZ and China's Ministry of Ecology and Environment signed a bilateral MoU on climate cooperation in London on 16 June 2025, establishing an annual ministerial dialogue and working-level exchanges. Cooperation areas include mitigation policy, carbon markets, climate finance, and methane measurement. No binding commitments, no funding, no rule changes.

Ofgem published final Tier 2 determinations on ten Capacity Market prequalification disputes for the 2025-26 Delivery Year. Appellants include Capbal (Kilwinning), OakTree Power, Northwold Solar Farm, Nextpower Rutherglen, Harmony KB, Flexion Energy (two appeals), ENGIE Power, Diodes Zetex Semiconductors, and Battery Box. The determinations review whether the Delivery Body correctly applied the Capacity Market Regulations and Rules to each original prequalification decision.

Ofgem consults on 13 Capacity Market rule change proposals (CP382-CP394). Proposals cover Independent Technical Expert definitions, termination reasons, load-following obligation calculations, metering test processes, and other operational rules. Consultation closes 24 May 2026.

DESNZ has issued a screening decision that a single 132 kV tower, cable sealing end platforms, and two underground cables at Musty Haulgh Farm, Burnley do not require a statutory Environmental Impact Assessment. The works are a minor modification to Electricity North West's existing 'DR' overhead line to connect a 152 MWh battery storage site that already has planning consent (FUL/2021/0375, granted July 2023). Burnley Borough Council confirmed no EIA needed on 15 December 2025; no public representations were received by the 3 April 2026 deadline.

Secretary of State makes corrections to The Morgan Offshore Wind Project Generation Assets Order 2025. The project has a minimum output of 1,400 MW. Administrative correction to an existing DCO.

Ofgem grants urgency to CMP470, a CUSC modification that would introduce commitment fees for developers holding grid queue positions in oversubscribed technology categories — primarily battery storage, which exceeds CP2030 targets by 14.8GW (2030) and 61.7GW (2035). The fee mechanism would price queue occupation for the first time, giving non-viable projects a financial reason to exit before signing Gate 2 connection agreements. Decision needed before Phase 1 offers are accepted from mid-August 2026.

NESO has published its 2026 Operability Strategy Report and Electricity Markets Roadmap, covering operational changes needed for clean power by 2030. The reports emphasise demand-side flexibility, stability pathfinder programmes, reserve product markets, and changes to minimum inertia requirements. A separate Visibility and Access Roadmap consultation on distributed energy resource oversight is open until April 2026.

NESO's March 2026 monthly energy statistics report GB's generation mix and demand. Wind set a new maximum generation record of 23,880 MW on 25 March, providing 60% of electricity at peak. Wind led the month at 34.8% of generation, gas second at 22.2%, with peak demand of 38,160 MW on 3 March.

NESO consults on a roadmap to gain operational visibility and dispatch access to distributed energy resources (DERs) and consumer energy resources (CERs) — commercial batteries, small-scale wind, EVs, rooftop solar, and home batteries. The consultation closes 30 April 2026 and seeks feedback on ambition, practicality, and completeness of proposed capabilities and data requirements. This is the system operator's bid to extend its operational reach below the transmission-distribution boundary.

NESO's Balancing Programme landing page aggregates updates on the Open Balancing Platform (OBP), control room capability journeys, and stakeholder engagement events. No new rules, charges, or decisions are announced. The page serves as a navigation hub for existing materials including webinar recordings, slide packs, and closure reports.

NESO's first Q&A workshop on GC0166 explains the MDO/MDB (Maximum Delivery Output/Bid) mechanism that replaces the 30-minute rule for battery dispatch in the Balancing Mechanism. Control points must submit minute-granularity energy availability data from real-time to 05:00 D+2, protecting volumes committed to frequency response and reserve contracts. Go-live is 22 June 2026, with transition running to November 2026 as individual control points certify readiness.

The Grid Code Review Panel met on 26 March 2026. Two new modifications were presented: GC0185 proposing dynamic regulation as an alternative to mandatory frequency response was sent back for clearer scope, and GC0187 (legal text corrections) was deferred over a drafting query. GC0139 on enhanced planning-data exchange between network operators and NESO was unanimously recommended to Ofgem.

CUSC Panel granted urgent treatment to CMP470, which introduces a commitment fee for grid connection technologies oversubscribed relative to Clean Power 2030 targets — a pricing mechanism for queue capacity. CMP440, which removes the zero price floor on demand TNUoS locational tariffs to restore locational investment signals, was unanimously recommended to Ofgem. CMP445 (pro-rated first-year TNUoS for generators) proceeds to Code Administrator Consultation opening 7 April 2026.

TCMF slidepack covers five substantive items: a proposed CUSC clause to let NESO share Large Embedded Generator red line boundaries with DNOs without customer consent; a proposed urgent modification to allow connection date delays during the ~30-month freeze ahead of the first CMP434 gate window; RWE flagging significant errors and missing appendices in Gate 2 Offers where network companies delayed connection dates; and NESO's proposal to model Sea Link HVDC tariffs on a north-to-south (Sizewell-to-Richborough) flow direction based on power flow studies showing 75% southward flow. The code administrator update lists CMP470 (Oversubscribed Technologies Commitment Fee) as a new urgent modification with nominations closing 2 April.

NESO consults on guidance for secondary generators — those with Grid Code obligations but no restoration contract — on how to comply with the Electricity System Restoration Standard (ESRS). The ESRS requires 60% of national demand restored within 24 hours and 100% within five days of a total or partial shutdown, with a compliance deadline of 31 December 2026. The guidance codifies existing Grid Code obligations around 72-hour plant resilience, cold start time declarations, communications testing, and cyber security under the NIS Regulations.

Secretary of State approves non-material change to North Killingholme CCGT (Uniper). Routine planning amendment.

Ofgem consults on the second preliminary Strategic Direction Statement, which sets binding priorities for how GB industry codes must develop under the Energy Act 2023 governance reforms. The SDS categorises policy areas requiring code changes and proposes converting from a preliminary to a hybrid document once BSC and REC are designated by end-2026. Responses due 28 May 2026.

Ofgem consumer blog explaining wholesale energy cost components and their transmission to bills via the price cap. Notes wholesale costs are ~40% of bills, gas sets marginal electricity price 'a large majority of the time', and NESO estimates gas could set the price just 30% of the time by 2030. Confirms Q2 2026 price cap fall reflects both lower wholesale prices and the fiscal transfer of environmental levy costs to general taxation.

Ofgem's standing reference page for the Feed-in Tariff scheme, which closed to new applicants on 1 April 2019. The page describes how FIT works: accredited generators receive quarterly payments from licensed suppliers for electricity generated and exported, with costs spread across all suppliers via levelisation. No new rules, rates, or deadlines are introduced.

Ofgem's FIT tariff and payments reference page sets out how generation and export tariffs are calculated for accredited installations under the closed scheme. Tariff rates are set by DESNZ and indexed to CPI from FIT Year 17 onwards, replacing the previous RPI indexation. The scheme closed to new applications on 1 April 2019 but continues to pay existing generators for their 20-25 year tariff periods.

Ofgem's FIT data portal page lists the standard suite of Feed-in Tariff reports: annual, quarterly, deployment caps, installation, and levelisation. This is an index page linking to existing datasets, not a new release. The FIT scheme closed to new applicants in March 2019; these reports track the legacy tail.

Ofgem has updated its FIT supplier guidance (Version 18) to reflect the government's mandated transition from RPI to CPI inflation indexation for FIT tariff adjustments, following the January 2026 consultation response. The update also includes a revised contact email for the RE Compliance Team.

Ofgem publishes the quarterly FIT levelisation report detailing total payments made by FIT licensees to accredited generators. This is a routine administrative publication — a landing page for downloading historical levelisation data. No new policy, no rule change.

Renewables Obligation certificates and generation statistics. Tracks ROC issuance volumes by technology and accredited generating stations.

Ofgem sets the RO buy-out price at £69.34/ROC for 2026-27, up 3.4% from £67.06, with the indexation basis switching from RPI to CPI following DESNZ's January 2026 decision. The obligation level drops slightly to 0.472 ROCs/MWh from 0.493. Mutualisation ceilings are £417.7m for England & Wales and £41.8m for Scotland.

Ofgem has approved NESO's request to increase the derogated volume of Mandatory Frequency Response (MFR) procurement from 120 MW to 300 MW — a 150% increase. The derogation allows NESO to procure MFR earlier than day-ahead and for contract periods up to one month, bypassing standard Grid Code procurement rules. All other terms of the January 2025 derogation remain unchanged, with expiry on 31 December 2029.

CMP470 proposes a commitment fee for technologies oversubscribed relative to Clean Power 2030 targets, aimed at forcing speculative projects out of the connection queue. The CUSC Panel voted by majority to recommend urgent treatment to Ofgem, with a final modification report targeted for 30 June 2026 under the urgent timeline versus April 2027 under standard process. The proposal was raised by Field Energy on 20 March 2026 after Gate 2 capacity data revealed approximately 90 GW of battery storage projects seeking connection points when roughly one third will actually connect.

Ofgem's RO annual report for Scheme Year 23 (April 2024–March 2025) shows 101.4 million ROCs issued against a supplier obligation of 119.5 million ROCs, with suppliers presenting 105.9 million ROCs and paying £613.7 million into buy-out and late payment funds. RO-accredited generation from 35.0 GW of capacity produced electricity equivalent to 30.2% of UK supply, rising to 46.6% when combined with FiT and CfD. Two supplier failures (Tomato Energy and Rebel Energy) created a £23.6 million shortfall, though this remained below the mutualisation threshold for the third consecutive year.

Ofgem publishes the 16th annual biomass sustainability dataset under the Renewables Obligation, covering Scheme Year 23 (2024-2025). The dataset reports against sustainability criteria introduced in 2009 for biomass-fuelled generating stations. It accompanies the RO Annual Report's biomass sustainability chapter.

Ofgem published its 63rd quarterly FIT report covering Q4 2025 (October-December), summarising installations, installed capacity, and levelisation for the scheme now in its 16th year. The scheme has been closed to new applicants since April 2019; this is routine monitoring of legacy obligations.

Elexon launching API-based asset registration for the Balancing Mechanism on 31 March 2026, linking to their Customer Solution Platform. Reduces friction for flexibility providers entering the BM.

The Distribution Code proposes consolidating EREC G98 and EREC G99 distributed generation connection guides into a single document. This annual revision follows Distribution Code requirements with consultation planned for March 2025. The change streamlines guidance for generators connecting at different scales rather than altering connection rules themselves.

The Distribution Code modification EREC G59 Issue 3 A8 adds supplementary sections to facilitate intentional islanding during system restoration processes. This builds on existing Engineering Recommendation G59 guidance for distributed energy resources. The modification enables controlled isolation of network sections while maintaining local supply during wider system recovery.

EREC G99 adds supplementary sections to facilitate intentional islanding during system restoration. This is a code modification to the distribution connection standard. The change enables grid-connected assets to operate in isolation when the grid is being restored after blackouts.

The Standard Application Form (SAF) v11 for EREC G99 connections updates the formal document used to apply for connecting power generating modules exceeding 16A per phase to distribution networks. The form covers solar, wind, battery storage, and other generation technologies connecting under G99 requirements. This appears to be a routine version update to existing connection application procedures.

Distribution network operators assess whether to create explanatory guidance supporting Engineering Recommendation P28 Issue 2, which sets technical standards for distributed generation connections. The proposed Engineering Report would provide additional technical application guidance but would not change P28 itself. No timeline or specific technical areas are identified.

CMP470 proposes introducing a commitment fee floor for all technologies that are oversubscribed relative to Clean Power 2030 capacity targets. The modification targets generation developers with high impact and transmission owners with medium impact. It is proceeding through urgent governance route to workgroup stage.

NESO expands its Demand Flexibility Service to allow participants to be rewarded for increasing electricity consumption during periods of excess supply, alongside existing rewards for demand reduction. The service threshold drops from 1MW to 0.1MW, opening participation to smaller suppliers and businesses. Over 2.46 million businesses and consumers have already signed up.

NESO published guidance on its connections reform programme, including a new delivery pipeline prioritising 381.5GW of 'ready-to-build' capacity and announcing permanent leadership structure under new Director of Connections Colm Murphy from 13 April. The reform moves from a chronological queue to a delivery pipeline based on project readiness, with claims of unlocking £40bn annual investment.

NESO establishes a programme to track and enable demand-side flexibility participation in its balancing services markets, targeting 10-12 GW of demand flexibility by 2030. The programme includes quarterly reporting of participation levels and a Routes to Market Review to remove barriers for demand-side participants. Data relies on self-reported confirmations from asset owners, with NESO encouraging non-respondents to contact them for comprehensive representation.

NESO publishes quarterly updates on its review to remove barriers preventing demand-side flexibility from participating in system operator markets. The review has completed three stages and now publishes quarterly progress reports tracking barrier removal, with a data dashboard monitoring participation volumes. The programme follows NESO's Clean Power 2030 advice identifying demand-side flexibility as essential for operating a decarbonised system.

Code modification GSR038 proposed to remove the requirement for two offshore AC transformers at grid entry points of 90MW or more has been withdrawn. The modification aimed to assess restrictions in Grid Code Clause 7.7.1.1 that effectively mandated dual transformer configurations. NESO classified it as having high impact on offshore transmission owners and generators.

DESNZ publishes the CHPQA Standard that sets Quality Index thresholds for Combined Heat and Power plants to qualify for 'Good Quality' certification. Different versions apply based on when schemes commenced operation or entered CfD contracts, with Issue 7 (December 2018) applying to CfD schemes, Issue 6 (September 2016) to schemes operating from 2016, and Issue 5 (November 2013) to earlier schemes. The Standard determines eligibility for various benefits excluding Renewables Obligation and Contracts for Difference support.

DESNZ and Ofgem propose mandatory baseline cyber security requirements for all 1,400+ Ofgem licensees through licence conditions, using Cyber Essentials certification as the starting point. The proposal also expands Network and Information Systems (NIS) Regulations to capture more distributed energy operators deemed critical to system stability. NESO will provide independent advice on which services and operators should fall under the enhanced NIS framework.

Ofgem and DESNZ propose baseline cyber security requirements for all energy licensees, plus expanded Network and Information System Regulations coverage. The consultation seeks to standardise cyber resilience across downstream gas and electricity sectors through mandatory minimum requirements. No specific thresholds, costs, or implementation dates are provided.

DESNZ launches new self-assessment portal for Combined Heat and Power Quality Assurance (CHPQA) scheme, replacing legacy digital service. CHP operators must register on the new portal to submit certification applications. Four existing forms (F1-F4) are now redundant.

DESNZ provides worked example for calculating Z-ratios through plant performance testing for combined heat and power qualification assessment. The example demonstrates solving simultaneous equations from three test conditions to determine specific electricity generation rates for different steam extraction points. This determines the Z-factor that measures efficiency loss when diverting steam for heat rather than electricity generation.

DESNZ requires Combined Heat and Power Quality Assurance (CHPQA) operators to report annual fiscal benefits received from certification including Climate Change Levy exemptions, Carbon Price Support reductions, and business rates relief. The guidance provides calculation methods for benefits worth millions annually to individual operators (£13.4m in example for 150 MW plant). This data collection supports policy development as government reviews CHP tax treatments.

DESNZ published updated CHPQA guidance for biomass and waste CHP schemes accessing support through the Renewables Obligation and Contracts for Difference. The guidance clarifies quality index calculations, certification requirements, and eligibility criteria for schemes claiming higher ROC payments or CfD support by demonstrating good quality CHP operation. It covers different fuel categories with specific formulae and includes safeguards for schemes supplying heating networks.

DESNZ guidance explains how CHP schemes with CHPQA certification can claim exemption from business rates on specific plant and machinery. The exemption covers power generation equipment (turbines, generators, engines) and accessories but excludes heat recovery plant and buildings. Schemes must hold a Secretary of State CHP Exemption Certificate and follow prescribed procedures with local Valuation Officers.

DESNZ has updated guidance on how combined heat and power (CHP) operators can use CHPQA certificates to claim exemptions from climate change levy and fuel duty. The guidance covers fuel input exemptions, carbon price support liabilities for schemes above 2 MWe, and electricity output relief calculations.

DESNZ publishes guidance on calculating Z ratios for Combined Heat and Power schemes with steam turbines, defining how to measure the trade-off between power generation and heat supply when steam is extracted at different pressures. The guidance provides reference tables showing Z ratios from 3.9 to 8.1 depending on turbine size (2-50+ MWe) and steam pressure (2.4-21.7 bar). Operators must determine their specific Z ratio through measurement or calculation, with fallback to tabulated values if testing is not feasible.

DESNZ updates guidance on calculating qualifying power capacity for combined heat and power schemes under the CHP Quality Assurance programme. The guidance sets minimum operational hours required for different scheme types (500-1000 hours annually) and establishes calculation methods for schemes that fail to meet quality index thresholds. This determines what proportion of CHP capacity qualifies for support mechanisms.

DESNZ updated guidance on calculating qualifying power output for CHP schemes that fail to meet minimum quality index thresholds. Schemes must achieve QI of 100 (or 95 for new schemes) for all power output to qualify as Good Quality CHP. Those below threshold must calculate reduced qualifying output using heat-to-power ratios and efficiency formulas.

DESNZ updates guidance on calculating qualifying fuel input for CHP schemes that fail to meet the 20% power efficiency threshold for Good Quality CHP status. The guidance provides a specific formula: CHPQFI = Annual Power Efficiency × Total Fuel Input ÷ Power Efficiency Threshold. This is version 3 of Guidance Note 25, published March 2026.

CHPQA Guidance Note 18 details how Combined Heat and Power operators should calculate and report uncertainties in energy input and output measurements when self-assessing their schemes for quality assurance purposes. The guidance provides mathematical methods for propagating measurement uncertainties through calculations, requiring operators to assign realistic uncertainty values and demonstrate overall uncertainty below specified thresholds. This updates technical procedures for an existing certification scheme that validates CHP efficiency claims.

DESNZ published a simple guide to the Combined Heat and Power Quality Assurance (CHPQA) programme, explaining application procedures for CHP certification. The guide covers registration, submission requirements for simple schemes (≤2 MWe, single reciprocating engine) versus complex schemes, and certification timescales. It also details how certified CHP operators can claim Climate Change Levy exemption, Carbon Price Support exemption, and renewable support through ROCs, CfDs, and RHI.

Government grants £64 million to Associated British Ports for design and engineering work to develop Port Talbot as a floating offshore wind port.
