Delaware's 1999 restructuring law (HB 10) authorized the state Public Service Commission (PSC) to develop environmental disclosure requirements and consumer protection standards for green power marketing. The PSC’s rules require all electric suppliers to disclose to the commission aggregate proportions of fuel resource mix for the electricity supplied to customers in Delaware for each quarter. In addition, electric suppliers must disclose their fuel resource mix to retail electric customers annually via bill inserts and "each other quarter' on the supplier's web site or by customer request. A standard label is not required; however, the reports must include:

  • The total number of Retail Electric Customers in each customer class that were served during the previous quarter
  • The total amount of electricity in kWh or MWh supplied to each customer class
  • The fuel resource mix by percentage of each resource
