Battery storage in Spain could become unviable beyond 32 GWh

Scientists from the University of Seville have developed real-time optimization models showing that electricity storage in Spain may be approaching its economic limit, with cumulative capacities above 32 GWh depressing prices and undermining project profitability.From ESS News Traditionally, storage planning has relied on production cost models or capacity expansion models. The former optimize dispatch based on levelized costs, while the latter assess investment decisions in a marginal pricing framework, typically assuming that thermal generation sets market prices. In both approaches, however, ...
