2023 ATB Errata

The following errata have been issued since the publication of the 2023 ATB:

January 29, 2024

The capacity factors for utility-scale PV were corrected to better account for degradation over the lifetime of the system. This also affects utility-scale PV-plus-Battery.
The project finance factor equation in the documentation was corrected to match the equation in the Excel spreadsheet.
Labels for geothermal equity and leverage during construction were corrected to match CFF equations.
The stated lifetime assumption for commercial and residential batteries in the data workbook were corrected to match the website.

The overnight capital cost (OCC) of the utility-scale PV-plus-Battery system was reduced to represent a 60-MW_dc battery with a 100-MW_ac PV array. The previous representation was correct for the cost of a 100-MW_dc battery with a 100-MW_ac PV array.
Corrected the representative wind plant O&M values in the documentation (no changes were made to the data).
Added links to fossil energy advanced case references, both in the documentation and in the data master spreadsheet.
