Regional Roundup Ranking

In the summer of 2014, Delaware enacted landmark legislation that will enable the first-ever ratepayer funded efficiency programs, including statewide coordination among the regulated and non-regulated utili­ties and the Sustainable Energy Utility. The 2015 and beyond Delaware Sustainable Energy Utility Strategic Plan was developed in concert with this legislation as a customized planning framework. The plan lays out the future course for new sustainable energy programs for residential and commercial and industrial sectors. Delaware also has a state energy plan that was developed in 2009. 

Through the stakeholder Energy Efficiency Advisory Council, Delaware’s energy office (DNREC) Division of Energy and Climate is continuing its progress toward initial energy efficiency program filings, pending the finalization of the proposed EM&V regulations issued in the summer of 2016. The parties are working through important issues like the creation of evaluation, measurement and verification regulations and deciding who will administer which programs to maximize effectiveness and ease of participation for customers and market actors alike.
