Grid-Scale Battery Storage: Frequently Asked Questions
The question of what role grid-scale battery storage plays in a power system has gained prominence because of the increasing need for power system flexibility coupled with the rapid decline in the cost of storage technologies, particularly lithium-ion batteries. More utilities and governments seek to determine whether battery storage is a cost-effective option for integrating large shares of variable renewable energy, such as wind and solar, into their power systems.
The USAID-NREL Partnership developed a fact sheet that provides the following information on grid-scale battery storage:
- Additional technical synopses about storage location
- Chemistry and sizing options
- Range of services storage can provide to a power system
- Means of compensation for battery energy storage systems service provision.
It also offers concrete steps and case study examples to show how jurisdictions have approached addressing barriers to battery deployment. This includes how to enable “value-stacking,” or the ability of batteries to provide (and receive compensation for) multiple system services.
