Grid-Scale Battery Storage: Frequently Asked Questions

The National Renewable Energy Laboratory (NREL) has released a fact sheet titled, "Grid-Scale Battery Storage: Frequently Asked Questions." This fact sheet addresses questions and concerns policymakers and grid system operators may have regarding grid-scale battery energy storage systems.

The full fact sheet can be read here. 

This fact sheet discusses issues and topics surrounding battery energy storage at a high level and is primarily geared towards regulators and grid-system operators. It addresses questions on the value of grid-scale battery energy storage to renewable energy integration, the services that batteries provide and key barriers to battery energy storage deployment. The fact sheet also provides examples of services grid-scale batteries can provide to the power system today and how these services can be combined through 'value-stacking,' as well as how the range of services battery systems can provide are determined by their location on the grid system.
