Notes:
- Data includes facilities with a total generator nameplate capacity of 1 megawatt (MW) or more. Solar data does not include distributed generation capacity.
- Government grants, tax benefits, or other incentives are excluded from these costs.
- Solar photovoltaic (PV) data are based on reported alternating current (AC) capacity and may differ from other cost and capacity estimates that use direct current (DC) ratings of PV panels.
- Petroleum liquids includes distillate fuel oil, jet fuel, kerosene, residual fuel oil, and waste oil.
- Biomass includes both liquid and gaseous biomass fuels.
- Some generation technologies were excluded from this analysis to avoid disclosure of individual company data.
- Average construction cost is based on the nameplate capacity weighted average cost per kilowatt of installed nameplate capacity.
- Total capacity is the sum of the nameplate capacity of generators included in each group.
- Average new capacity is based on the nameplate capacity of new plants or new additions of nameplate capacity to existing plants. New plants did not previously have operable units and are typically recently constructed. Existing plants have at least one previously operable generator and are not newly constructed.
- Totals may not equal sum of components due to independent rounding.
