Combined output of independent PV + storage plant (left figure) is as high as 70 MW, which is possible because of the separate inverters. DC-coupled system (right figure)—with shared 50-MW inverter—must shift storage output to lower-price periods to accommodate PV output.
In all cases the 30% ITC is applied to the PV portion of the system. Benefit/cost ratios are calculated by dividing annualized benefits by costs. The PV-only system has the highest benefit/cost ratio. These results follow historical trends that have resulted in very limited deployment of PV plus storage systems.
Result is a total capacity value of $7.5 million/year. DC-coupling causes no decline in capacity value, because the PV capacity credit (20 MW) plus the storage capacity (30 MW) equals the inverter capacity of 50 MW. Independent, AC-coupled, and DC-coupled (flexible charging) storage receives 7-year MACRS (Modified Accelerated Cost Recovery System).
DC-coupled system (right figure)—with shared 50-MW inverter—must shift storage output to lower-price periods to accommodate PV output. DC-coupled system value decreases by about 1% relative to independent PV + storage system. Impacts of DC tightly coupled storage systems are more significant.
