What is a PV O&M plan?
For larger utility or commercial scale systems a detailed PV O&M plan prepared by the owner, EPC firm, and/or the developer and accepted by the asset manager is the only long-term operations plan for a PV system.
What are the requirements for large PV power plants?
Large PV power plants (i.e., greater than 20 MW at the utility interconnection) that provide power into the bulk power system must comply with standards related to reliability and adequacy promulgated by authorities such as NERC and the Federal Energy Regulatory Commission (FERC).
What is a PV O&M cost model?
The PV O&M cost model allows a customized, if not more accurate, estimate of system cost based on system type and components and on environmental conditions. Survey data on cost and backup service providers are being correlated with model test data to “calibrate” the cost model.
Should a PV O&M plan include decommissioning?
Include decommissioning in the PV O&M plan and/or asset management. The residential and small commercial O&M focus is on fleet performance goals rather than individual systems; meeting performance warranties of individual systems to meet customer satisfaction goals should be balanced against cost and cash-flow optimization.
