Notice of proposed modifications to Re-opener Guidance and Application Requirements Document
Summary
Ofgem consults on proposed modifications to the Re-opener Guidance and Application Requirements Document used by network companies submitting re-opener applications under RIIO-2.
Why it matters
Process refinement for the re-opener mechanism. Tighter Application Requirements raise the evidence bar for network companies; looser requirements speed throughput. Mostly affects regulatory submissions rather than the substantive size of re-opener allowances.
