Share the page

Later this year, Ofgem and the Independent Performance Panel will assess the Electricity System Operator's (ESO) performance over the last 2 years of the Business Plan 1 period of the RIIO-2 price control. This call for evidence requests stakeholder input on the ESO's performance.

We welcome any feedback on the ESO's three roles and its deliverables laid out in its business plan from April 2021 to date. This includes areas where you feel the ESO has met, exceeded or failed to meet any expectations. Please send written feedback to esoperformance@ofgem.gov.uk by 20 April 2023.
