Operation and Maintenance (O&M) Costs

Definition: Operation and maintenance (O&M) costs represent the annual expenditures required to operate and maintain a CSP plant over its lifetime, including items noted in the Summary of Technology Innovations by Scenario table above.

Base Year: FOM is assumed to be $68/kW-yr until 2021. Variable O&M is approximately $4.20/MWh until 2021 and $3.60/MWh after that (Kurup and Turchi 2015).

Future Years: Future FOM is assumed to decline to $52/kW-yr by 2030 in the Moderate Scenario (i.e., approximately a 25% drop) and approximately $41/kW-yr by 2030 in the Conservative Scenario based on DOE investments that are likely to help to lower costs (DOE 2012).

Use the following table to view the components of operating expenditures.
