The drivers for grid-level energy storage are rapidly decreasing cost of energy storage, and the multitude of benefits provided by energy storage to the grid in general and to grids with high penetration of renewable energy in particular. The rapid decrease in cost is primarily driven by rapid innovation and scale in the electric vehicle market.
Energy storage is a solution for addressing these concerns. The third chapter describes the various roles and applications of energy storage in a grid. The applications are grouped into four clusters—bulk energy services, ancillary services, dispatch-ability, and transmission and distribution deferral.
It has also led to large-scale production facilities (gigawatt factories) for energy storage, which promises to achieve reduction in costs similar to those seen in solar photovoltaic industry. The focus of this report is on energy storage for the power grid in support of larger penetration of renewable energy.
The benefits of grid-level energy storage, as described above, cover a wide gamut of services—energy time-shift, ancillary services, making renewable energy dispatchable, deferring transmission and distribution upgrades, and others.
Fast acting and bidirectional energy storage can stabilize the grid by storing and delivering energy within a few microseconds; the types of energy storage devices that have these capabilities include electrochemical batteries like lithium-ion, flywheel, and capacitors.
Energy storage can alleviate this problem by storing the curtailed energy and delivering it during times of peak demand. A business case for energy storage in this situation involves detailed analysis of largest duration of curtailment, diferential in price of energy from time periods of peak and of-peak demand, and others.
