电能存储（EES）的文献是技术性的和复杂的，本文旨在简化。它量化了不同类型的EES的当前规模、成本和价值，并将其与调峰发电机和互联网进行了比较。在世界范围内，大坝的储存能力是抽水蓄能的2,700倍，抽水蓄能占传统EES的99%，其余部分由电池组成。间接使用水力发电，以及未来的电动汽车，增加了它们的价值，如果以合理的成本获得，将比传统的EES更便宜。EES、扬声器和直流互连器可以提供灵活的服务，大大提高其价值，但电池革命实现更智能电力系统的希望不应被夸大。
The literature on electrical energy storage (EES) is technical and complex which this paper aims to simplify. It quantifies the current scale, costs and value of different types of EES and compares them to peaking generators and interconnectors. Worldwide, dams have 2,700 times the storage capacity of pumped storage, which accounts for 99% of conventional EES, batteries making up the rest. Indirect use of hydro power, and in future, electric vehicles, adds to their value and if accessible at reasonable cost, would be cheaper than conventional EES. EES, peakers and DC interconnectors can offer flexibility services which considerably enhance their value, but hopes of a battery revolution enabling a smarter electricity system should not be exaggerated.
