The Energy Information Administration dataset includes information such as peak load, generation, electric purchases, sales, revenues, customer counts and demand-side management programs, green pricing and net metering programs, and distributed generation capacity. Dispersed generation (NOT grid-connected) are for companies that own or operate a distribution system. Dispersed generators could be utility-owned or customer-owned. The dataset includes the number of generators, number of generators less than one megawatt, total aggregate capacity, aggregate capacity used only for backup, and capacity by technology type. Respondents specify whether data are actual or estimated.
The dataset compiled by National Renewable Energy Laboratory (NREL) using data from ABB, the Velocity Suite and the U.S. Energy Information Administration dataset 861, provides average residential, commercial and industrial electricity rates by zip code for both investor-owned utilities (IOU) and non-investor owned utilities. The file includes average rates for each utility, but not the detailed rate structure data found in the Open EI U.S. Utility Rate Database. A more recent version of this data is also available through the NREL Utility Rate API with more search options. This data was released by National Renewable Energy Laboratory (NREL)/Ventyx in February 2011.
