Electric Regulation

Table of Contents

New Electric Supplier/Broker Certification rules and regulations (Regulation Docket 49) become effective April 11, 2017. These Regulations impact the certification process for Suppliers and Brokers, as well as the requirements for contracts, contract summaries, marketing plans and materials for Suppliers/Brokers who market to Residential and Small Commercial Customers. Additional information can be found by searching, REG. 49 in DelaFile.

Role 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)
