From January to June 2011, 162 electric power generators were added in 36 states, for a total of 11,255 megawatts (MW) of new capacity. Of the ten states with the highest levels of capacity additions, most of the new capacity uses natural gas, coal, or wind. Capacity additions in these ten states total 8,504 MW, or 76% of the national total for the first six months of 2011.
Year-to-date state profiles underscore different trends based on the number of generators added.
- Many of the generators represented in the chart above are fairly large (capable of producing hundreds of megawatts of power). Texas, Kentucky, Wisconsin, and Missouri, for instance, each added a single, large coal-fired generator between January and June of 2011.
- New generators using renewable energy sources are more numerous, but are often smaller. Of these, the two most common fuels are landfill gas (added in Florida, North Carolina, Ohio, Pennsylvania, Texas, Virginia and West Virginia) and solar (added in California, Colorado, Delaware, Florida, North Carolina, New Jersey, New Mexico, Pennsylvania, and Vermont).
These data represent responses to EIA's monthly update survey of existing electric generators. An annual survey will collect final data from all industry participants early next year.
