We estimate that in high-resource regions, with optimal resource mixes, low storage energy capacity costs (<$20/kWh) are necessary for cost-competitive, reliable baseload electricity generation. However, when other technologies meet 5% of demand, costs can be halved, even with significantly more expensive storage.
