Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible.
In addition, storage at any level can offer system services, safeguarding the secure and efficient operation of the electricity system. Storage can help defer costly investments in transmission and distribution infrastructure, extending the lifetime of existing assets and helping grids function more efficiently.
Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms. Some technologies provide short-term energy storage, while others can endure for much longer. Bulk energy storage is currently dominated by hydroelectric dams, both conventional as well as pumped.
The so-called battery “charges” when power is used to pump water from a lower reservoir to a higher reservoir. The energy storage system “discharges” power when water, pulled by gravity, is released back to the lower-elevation reservoir and passes through a turbine along the way.
The length of time an ESS can supply electricity varies by energy storage project and type. Energy storage systems with short durations supply energy for just a few minutes, while diurnal energy storage supplies energy for hours.
Storage enables electricity systems to remain in balance despite variations in wind and solar availability, allowing for cost-effective deep decarbonization while maintaining reliability. The Future of Energy Storage report is an essential analysis of this key component in decarbonizing our energy infrastructure and combating climate change.
