The electricity sector ATB website provides consistent, freely-available technology-specific cost and performance parameters across a range of R&D advancements scenarios, resource characteristics, sites, fuel prices, and financial assumptions for electricity-generating technologies, both at present and with projections through 2050. It includes capital expenditures, operations expenditures, and capacity factor and also the levelized cost of energy, a summary metric for electricity-generating technologies.
Use the charts and table below to explore ranges, projections, and a tabular summary of ATB data. Interact with the chart, including selection of other parameters, by clicking "More Details" to explore the meaning of the data.
You can also download 2020 ATB data.
The figures and table illustrate the selected data dimensions, which are developed using the assumptions described briefly here with links to additional information.
The specifics of representative technologies, parameter definitions, historical trends, current estimates, and future projections used in the ATB are described in the respective technology section. Links to definitions provide information that applies to all technologies
The levelized cost of energy is a summary metric that combines capital expenditures (CAPEX), operations expenditures (O&M), capacity factor, and projections for "conservative", "moderate", and "advanced" technology advancement scenarios. See levelized cost of energy for information about important limitations of LCOE.

The ATB provides original technology advancement scenarios for renewable electricity-generating technologies. The Conservative, Moderate, and Advanced scenarios that appear in tables and figures refer to a range of assumptions about technology advancement and associated cost and performance. For reference, the ATB provides natural gas, coal, nuclear, and biopower data.
Financial assumptions impact LCOE by changing the cost of capital to finance electricity generation projects. Two project finance structures are used within the ATB: a R&D Only Financial Assumptions Case (R&D Only case) and a Market + Policies Financial Assumptions Case (Market + Policies Case). Independent power producer financing structure is assumed.
The ATB displays three cost recovery period options.
Each of the technology-specific pages describes the assumptions and methodologies used to develop the data.
Technology detail indicates resource level and specific technology sub-categories.
Please refer to the 2020 ATB Approach and Methodology for details about the methods used to develop the cost and performance projections.
