1. Introduction Future energy systems based on renewable technologies need a high degree of flexibility, stemming, for example, from transmission systems [1], sector integration [2], demand-side management [3], curtailment of excess energy [4], and storage systems [5].].
Storage can provide similar start-up power to larger power plants, if the storage system is suitably sited and there is a clear transmission path to the power plant from the storage system''s location. Storage system size range: 5–50 MW Target discharge duration range: 15 minutes to 1 hour Minimum cycles/year: 10–20.
Our research shows considerable near-term potential for stationary energy storage. One reason for this is that costs are falling and could be $200 per kilowatt-hour in 2020, half today''s price, and $160 per kilowatt-hour or less in 2025. Another is that identifying the most economical projects and highest-potential customers for storage has
