Fuel Mix Disclosure
Quick Summary
Delaware's fuel mix disclosure requirement ensures that all electric suppliers—whether you choose a third-party supplier or stay with your utility—must tell you annually what percentage of your electricity comes from different fuel sources (coal, natural gas, renewables, etc.), typically via bill inserts or their website. This transparency helps you understand the environmental impact of your power source and make informed choices if you're considering switching to a green power supplier among the many active options available in Delaware.

Program Summary
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 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
