Generating Unit Annual Capital and Life Extension Costs Analysis

Release date: December 4, 2019

Addendum - Updates to Cost Assumptions in the Electricity Market Module (EMM) of the National Energy Modeling System (NEMS) Release date: December 4, 2019

In a period of accelerating retirements of electric power generators, EIA sought to revisit its assumptions of age-related generation costs. EIA commissioned Sargent & Lundy (S&L) to evaluate capital expenditures (CAPEX) and operations and maintenance (O&M) costs for non-nuclear generating units, with a particular emphasis on how costs of coal and other fossil-fueled plants change over time. The following report represents S&L’s findings. A separate EIA report, Updates to Cost Assumptions in the Electricity Market Module (EMM) of the National Energy Modeling System (NEMS), details subsequent updates to the EMM module.

The following report was accepted by EIA in fulfillment of contract number DE-EI0003250. All views expressed in this report are solely those of the contractor and acceptance of the report in fulfillment of contractual obligations does not imply agreement with nor endorsement of the findings contained herein. Responsibility for accuracy of the information contained in this report lies with the contractor.
