Operations and Maintenance
Renewable energy projects, while typically low-maintenance, are not no-maintenance. With proper attention to details during construction, operation and maintenance (O&M) of simple grid-connected solar electric (photovoltaic) systems require minimal maintenance. Larger wind systems will require periodic lubrication. Biomass systems will likely require maintenance of material handling equipment, and disposal of waste products such as ash. Each renewable energy technology will have its own operating and maintenance requirements, however minimal. The equipment supplier should be required to provide an O&M manual, including specified maintenance needs and maintenance intervals. Any special tools required for O&M activities should be supplied with the equipment, and responsible staff should be trained in their use.
