Presented below are graphs and tables of the cost data for generators installed in 2020 based on data collected by the 2020 Annual Electric Generator Report, Form EIA-860. The cost data for certain generation technologies were omitted to avoid disclosure of individual company data.
EIA expects to publish construction cost data for generators installed in 2021 in July 2023.
