O&M stands for Operations and maintenance, an engineering abbreviation.
Activities and costs involved in running and maintaining a facility or asset after it is built, including staffing, inspections, repairs, spare parts and routine servicing. O&M costs are a major factor when comparing power plants, buildings and infrastructure over their lifetimes.
Example: The wind farm's 20-year O&M contract covers scheduled servicing and replacement of major components.
Usage notes
O&M manuals are handed over at project completion and describe how to operate and maintain installed equipment. In energy economics, O&M is split into fixed costs, paid regardless of output, and variable costs that rise with production.
