Department of State : Delaware Public Service Commission


PSC logo


In 1999, the General Assembly passed legislation restructuring the electric industry in Delaware. Prior to restructuring, the generation, transmission, and distribution of electric power by investor-owned utilities was fully regulated by the PSC. With restructuring, the generation of electric power became deregulated, leaving only distribution services under the regulatory control of the PSC. The pricing of electric transmission is regulated by the Federal Energy Regulatory Commission (FERC).

In 2006, faced with significantly increase energy costs, the General Assembly passed a revision to the restructuring legislation entitled "The Electric Utilities Retail Supply Act of 2006." The Act provides that all electric distribution companies subject to the jurisdiction of the Commission would be designated as the standard offer service supplier and returning customer service supplier in their respective territories. The Act provided further opportunity for distribution companies to enter into long and short-term supply contracts, own and operate generation facilities, build generation and transmission facilities, make investments in demand-side resources and take any other Commission approved action to diversify their retail load supply. Additionally, Delmarva Power is required to conduct Integrated Resource Planning for a forward-looking 10 year time frame and to file such plan with the Commission, the Controller General, the Director of the Office of Management and Budget and the Energy Office every two years starting with December 1, 2006. As part of the initial planning process, Delmarva Power is required to file a proposal to obtain long-term supply contracts. The proposal requires Delmarva Power to include a Request for Proposal (RFP) for the construction of new generation resources within Delaware. Delaware IRP/RFP
