Canales et al., proposed a model to estimate the optimal sizing of an off-grid hybrid power system coupled with a hybrid pumped-battery storage system . The obtained cost of energy ranges between 0.047 €/kWh and 0.095 €/kWh for the considered case study .
The reason is that such off-grid locations exhibit known, constant backup costs as they typically have only one type of generator as backup, no merit ordering, and no capacity or energy auctions. As a consequence, the value of solar is easy to compute and equal to the cost of the backup generation it replaces.
