Statement on SSE’s decision to appeal Ofgem’s rejection of CMP261

SSE is disappointed with Ofgem’s decision on 16 November 2017 to reject the Connection and Use of System Code modification proposal, CMP261. SSE raised CMP261 in March 2016 to ensure compliance with European Union Regulation 838/2010, which restricts the average transmission charges paid by generators in EU member states. The modification proposal would introduce a rebate for generators who were overcharged for using the national transmission system in the 2015/16 charging year.

It is estimated that the exceedance in the average annual Transmission Network Use of System (TNUoS) charges paid by GB generators in 2015/16 amounted to around €3.25/MWh, an overcharge of 25% over the upper limit in Regulation 838/2010.  As a result, SSE, together with EDF Energy, will now appeal Ofgem’s decision on CMP261 to the Competition and Markets Authority (CMA).
