Grid energy storage, also known as large-scale energy storage, is a set of technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power, releasing it when needed.
Under some conditions, excess renewable energy is produced and, without storage, is curtailed 2, 3; under others, demand is greater than generation from renewables. Grid-scale energy-storage (GSES) systems are therefore needed to store excess renewable energy to be released on demand, when power generation is insufficient 4.
With widespread grid failures on this scale, energy storage would have to make up a much larger share of system capacity than it currently does to change the dynamics, although it can respond to sudden system fluctuations by providing ancillary services, like frequency and voltage regulation.
The rise in renewable energy utilization is increasing demand for battery energy-storage technologies (BESTs). BESTs based on lithium-ion batteries are being developed and deployed. However, this technology alone does not meet all the requirements for grid-scale energy storage.
As a result, the grid has historically relied on more flexible resources, such as natural gas or hydropower, to meet sudden changes in demand. Energy storage and demand response add additional flexible resources to the system operator’s toolkit, providing them with more options for balancing the grid.
States are also developing expert task forces and committees to evaluate storage technologies and opportunities for growth. Maine, for example, enacted HB 1166 (2019) creating a commission to study the benefits of energy storage in the state’s electric industry.
