Capital Expenditures (CAPEX): Historical Trends, Current Estimates, and Future Projections

Nuclear power plant CAPEX is taken from the AEO2019 Reference Scenario (EIA, 2019a) with the adjustments discussed in the CAPEX definition section. The EIA advanced nuclear option is based on two AP1000 nuclear power plant units built on a brownfield site. The ATB includes only a single CAPEX projection for nuclear plants.

Current estimates and future projections calculated from AEO2019 (EIA, 2019a) and modified.
R&D Only Financial Assumptions (constant background rates, no tax changes)

Comparison with Other Sources

ATB cost numbers are for a brownfield nuclear facility.
Data sources include the ATB, Black & Veatch (2012), Entergy Arkansas (2015),Varro and Ha(2015), and Lazard (2016).
All sources have been normalized to the same dollar year. Costs vary due to differences in system design, methodology, and plant cost definitions.
