These included questions on: whether the availability target in the extension period should remain the same as in the original tender period related requirements for the amount OFTOs should include within the performance reserve our approach to partial and interim awards for investment works and Health Review costs; risk sharing around early withdrawal for both generators and OFTOs the resulting scope and review of Extension Revenue Stream ( ERS ) bids We also asked questions on the length of the Tender Revenue Stream ( TRS ) and whether it should be extended past the current term of 25 years, and on extending the Generator Commissioning Clause ( GCC ) and the consequential impacts for the tender period. This document covers the decisions that Ofgem has taken on EoTRS issues and the extension of the TRS, after carefully considering feedback from stakeholders to our December 2024 consultation.
