As part of a two-part workshop on European Experience with Energy Efficiency Obligations (EEOs) in Warsaw, Poland, RAP Senior Advisor Eoin Lees provided insight into the role of the UK Energy Regulator, Ofgem, as administrator of the nation’s EEO scheme. These plans require energy providers, such as electricity and gas companies, to meet quantitative energy saving targets through assisting their customers with the implementation of energy efficiency measures. Ofgem allocates the targets to the energy retailers and determines the administrative requirements imposed on the obligated energy retailers, while also ensuring quality standards and determining the actual energy savings in order to report back to the Government on the scheme’s progress. Mr. Lees explores these specific evaluation, measurement, and verification (EM&V) obligations in his presentation.
