EBGL: Electricity Balancing Guideline
Commission Regulation (EU) 2017/2195 (EBGL) is the principal EU-derived regulation governing how electricity balancing markets operate. In GB it remains live law, retained under the European Union (Withdrawal) Act 2018 and operative as assimilated law. Unlike CACM and FCA - which lost most of their operative content on Brexit - EBGL kept its domestic governance core intact.
65 Articles across 10 Titles. Approximately 37 are operative in GB; approximately 28 are omitted.
What It Does
EBGL establishes the governance framework for how NESO (as the GB TSO) procures and settles balancing services. It mandates:
- Market-based procurement of frequency containment reserves (FCR), frequency restoration reserves (FRR), and replacement reserves (RR) - with annual reserve requirement review (Art 32)
- Self-dispatching model - generators determine their own schedules; NESO does not centrally dispatch (Art 14)
- BSP prequalification - all balancing service providers must qualify via routes set in SOGL Arts 159 and 162 (Art 16)
- BRP financial responsibility - balance responsible parties bear the financial cost of their imbalances (Art 17)
- 15-minute imbalance settlement period - required within 3 years of entry into force, with derogation mechanism (Art 53)
- Imbalance pricing - prices must reflect the real-time value of energy, incentivising BRP self-balancing (Arts 52-55)
- TSO financial neutrality - NESO must not profit from settlement outcomes (Art 44)
- T&Cs for BSPs and BRPs - NESO must develop and publish detailed terms and conditions governing qualification, procurement, and settlement (Art 18)
What Is Live in GB vs What Was Omitted
This distinction is crucial. EBGL was designed around four EU-wide balancing platforms as the efficiency engine. All four were omitted on Brexit.
Live in GB
- All of Title I (Arts 1-13): governance, objectives, cost recovery, publication, consultation
- Title II Chapter 1 (Arts 14-18): TSO, DSO, BSP and BRP roles and obligations
- Art 28: fall-back procedures if procurement fails
- Arts 32, 34: capacity procurement rules; transfer of balancing capacity between BSPs
- Title V (Arts 44-49, 52-56): the full settlement framework - principles, balancing energy settlement, imbalance calculation and settlement, capacity settlement
- Art 60: biennial TSO balancing report
- Art 61: cost-benefit analysis obligations
- Art 62: derogations (including for 15-minute ISP)
Omitted in GB (31 December 2020)
| Group | Articles | What was lost |
|---|---|---|
| EU balancing platforms | 19-27 | TERRE, MARI, PICASSO, IGCC platform obligations and standard products |
| Common merit order | 29-31 | Activation from pan-European merit order list; pricing for cross-zonal exchange |
| Cross-border capacity exchange | 33, 35, 36-43 | Exchange and sharing of balancing capacity between TSOs; all cross-zonal capacity use for balancing |
| Cross-TSO settlement | 50-51 | Settlement of intended and unintended cross-border energy exchanges |
| Cross-border capacity settlement | 57 | Settlement for capacity procured outside scheduling area |
| EU algorithms | 58 | Activation optimisation function |
| EU reporting | 59, 63 | ENTSO-E annual report; ACER monitoring |
| NI transitional | 64 | Single electricity market transitional provisions |
The practical consequence: NESO operates a closed domestic merit order. There is no regulatory framework for using GB's interconnectors (BritNed, IFA, ElecLink, Viking Link, NordLink) for balancing services under EBGL. GB cannot benefit from cross-border competition in balancing markets.
The Four EU Balancing Platforms GB No Longer Participates In
EBGL was built around four platforms operated by European TSOs collectively:
TERRE (Trans-European Replacement Reserves Exchange) - Article 19. A platform for exchanging replacement reserve energy across EU TSOs, enabling low-cost providers in one country to activate reserves for another.
MARI (Manually Activated Reserves Initiative) - Article 20. A platform for cross-border exchange of manually activated frequency restoration reserve (mFRR) energy.
PICASSO (Platform for International Coordination of Automated Frequency Restoration and Stable System Operation) - Article 21. A platform for cross-border exchange of automatically activated frequency restoration reserve (aFRR) energy.
IGCC (International Grid Control Cooperation) - Article 22. A platform for imbalance netting: TSOs with opposite-direction imbalances cancel them against each other before activating balancing services, reducing costs system-wide.
GB lost access to all four on 31 December 2020. NESO cannot participate regardless of any commercial desire to do so, because the legal obligation to develop the terms and conditions for participation no longer exists in GB law.
15-Minute ISP Requirement (Article 53) and BSC Modifications
Article 53(1) requires all TSOs to apply a 15-minute imbalance settlement period (ISP) within 3 years of entry into force - i.e., by December 2020. GB historically operated 30-minute settlement.
The BSC modifications P305 and P306 introduced 30-minute settlement (halving from the legacy 30-minute market time unit arrangement) but did not achieve the full 15-minute requirement.
The derogation mechanism in Art 62(2)(d) allowed Ofgem to grant exemptions from the 15-minute requirement, but only until a maximum of 1 January 2025. After that date, no new ISP derogation can be granted under EBGL.
This means the 15-minute ISP obligation in Art 53(1) is technically outstanding for GB as at April 2026. Whether a compliant derogation was obtained before 1 January 2025, and what the regulatory position is thereafter, is an active compliance question for NESO and Ofgem.
How EBGL Interacts with BSC and NESO Licence
EBGL sets framework obligations; the BSC and NESO Transmission Licence translate them into operational rules.
EBGL Art 18 requires NESO to develop terms and conditions for BSPs and BRPs. These T&Cs are operationalised through the BSC, which is the primary domestic instrument for: - Imbalance settlement (BSC Section T implements Arts 52-55) - BRP registration and balance responsibility (BSC Section B implements Art 17) - Balancing energy settlement with BSPs (BSC Sections P and Q implement Arts 45-49) - Market Index and cash-out pricing (BSC's implementation of imbalance price rules in Art 55)
NESO Transmission Licence implements the TSO procurement obligations, stakeholder consultation requirements, and reporting duties (Art 60).
The Grid Code implements BSP prequalification and technical requirements referenced in EBGL Arts 16 and 18.
The regulatory hierarchy runs: EBGL (framework) - BSC and NESO Licence (detailed rulebook) - operational instructions (NESO procedures and Grid Code annexes).
