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.

Why are lithium batteries cheaper than lead-acid batteries?
We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology. The reason is related to the intrinsic qualities of lithium-ion batteries but also linked to lower transportation costs.
Are battery storage costs based on long-term planning models?
Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
Are lithium-based solutions cheaper than lead-acid solutions?
In summary, the total cost of ownership per usable kWh is about 2.8 times cheaper for a lithium-based solution than for a lead acid solution. We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology.
Do longer duration batteries have a lower capital cost?
As expected, on a $/kWh basis, longer duration batteries have a lower capital cost, and on a $/kW basis, shorter duration batteries have a lower capital cost. Figure 7 also demonstrates why it is critical to cite the duration whenever providing a capital cost in $/kWh or $/kW. Figure 7.
