An energy efficiency obligation (EEO) requires obligated parties to meet energy savings targets by delivering or procuring eligible energy savings as a result of approved end-use energy efficiency (EE) measures. An effective EEO scheme establishes a framework for defining eligible energy savings activities, methods for measuring and verifying the resulting energy savings, and confirming that the activities actually took place. Speaking at an energy efficiency obligation workshop hosted by the Latvian Ministry of Economics, Mr. Lees drew on examples from Great Britain and France to illustrate the eligibility criteria applied to EE measures and outlined the considerations for disqualifying measures that do not ultimately result in end-use energy savings. Deemed energy savings—extrapolated from the results of previously independently monitored energy improvements in similar installations—have proven to be a popular route due to their guaranteed energy savings, simplified marketing to consumers, and mass replicability.
