The Federal Energy Regulatory Commission released its most recent 7-page “Energy Infrastructure Update,” on Feb. 7, 2016 with data through Dec. 31, 2015. See the tables titled “New Generation In-Service (New Build and Expansion)” and “Total Installed Operating Generating Capacity” here.
Sources: Data derived from Velocity Suite, ABB Inc. and The C Three Group LLC which include plants with nameplate capacity of 1 MW or greater. The data may be subject to update. * “Other” includes purchased steam, tires, and miscellaneous technology such as batteries, fuel cells, energy storage, and fly wheel.
Note that generating capacity is not the same as actual generation. Electrical production per MW of available capacity (for example, capacity factor) for renewables is often lower than that for fossil fuels and nuclear power. According to the most recent data (for example, as of Nov. 30, 2015) provided by the U.S. Energy Information Administration, actual net electrical generation from utility-scale renewable energy sources now totals about 13.2% of total U.S. electrical production (see here; however, this figure understates renewables’ actual contribution because neither EIA nor FERC fully accounts for all electricity generated by distributed renewable energy sources [for example, uncounted U.S. rooftop solar is equal to about 45% of utility-scale solar capacity].)
