提供峰值容量可能是美国储能的一个重要市场。特别值得关注的是，由于多个地区的规定，续航时间为 4 小时的电池，以及与更长续航时间的电池相比，这些电池有可能实现与燃气轮机的生命周期成本相当。然而，4小时储能能否提供峰值容量很大程度上取决于电力需求的形状。在历史电网条件下，超过全国约 28 GW 后，4 小时电池提供峰值容量的能力开始下降。我们发现，增加可再生能源发电可以通过改变净需求模式的形状来显着提高存储潜力；例如，当太阳能光伏发电的普及率超过 10% 时，全国 4 小时储能提供峰值容量的实际潜力将增加一倍。风力发电的影响尚不明确，考虑到跨多个地区的风电交换，可能需要进行更详细的研究。
Providing peaking capacity could be a significant U.S. market for energy storage. Of particular focus are batteries with 4-h duration due to rules in several regions along with these batteries’ potential to achieve life-cycle cost parity with combustion turbines compared to longer-duration batteries. However, whether 4-h energy storage can provide peak capacity depends largely on the shape of electricity demand. Under historical grid conditions, beyond about 28 GW nationally the ability of 4-h batteries to provide peak capacity begins to fall. We find that the addition of renewable generation can significantly increase storage’s potential by changing the shape of net demand patterns; for example, beyond about 10% penetration of solar photovoltaics, the national practical potential for 4-h storage to provide peak capacity doubles. The impact of wind generation is less clear and likely requires more detailed study considering the exchange of wind power across multiple regions.
