Opens in new windowRole of the Commission

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) Opens in new window
