Does more solar and wind mean more storage value?
“Our results show that is true, and that all else equal, more solar and wind means greater storage value. That said, as wind and solar get cheaper over time, that can reduce the value storage derives from lowering renewable energy curtailment and avoiding wind and solar capacity investments.
Does the value of PV-wind systems reflect avoided energy and capacity costs?
Therefore, in this work, the value of PV-wind and PV-wind-battery systems reflects avoided energy and capacity costs and not market revenue. All the configurations explored in this analysis have a POI capacity of 100 MW AC, a PV capacity of 100 MW AC, and a storage duration of 4 h.
How much does solar and wind curtailment drop if storage is mandated?
We find that solar and wind curtailment drops as up to 20 TWh if storage is mandated (Fig. 5a). The WECC’s yearly renewable curtailment drops sharply from 118 GWh in the baseline to 9.6 GWh in the 20 TWh of storage scenario (−92%). Beyond this point, the impact is much more gradual.
How much solar energy does the WECC have?
In the most solar-dominant scenario (91% solar, 9% wind, i.e., five times more solar than wind), the WECC has 243 GW of 6-to-10-h storage and this amount drops roughly linearly to 97 GW In the most wind-dominant scenario (40% solar, 60% wind) (Supplementary Fig. 2).
Does wind capacity affect the summer capacity credit of PV-wind systems?
The relatively high summer capacity credit of standalone PV (∼80% and higher at all but one site) means that there is less opportunity for added wind capacity to increase the total capacity credit. As a result, the summer capacity credits of PV-wind systems are not well predicted by either wind capacity or stability coefficient.
Do solar and wind dominant grids require different storage durations?
Solar and wind dominant grids are expected to require different storage durations since solar has a diurnal cycle and wind might not.
