How are energy storage systems regulated?
In some contexts, for energy storage systems, compliance regulations take the form of a state adopting a code, which then references and requires testing and listing or adherence to a standard. Some cities, counties, and special administrative districts (e.g., school or sewer districts) also adopt locally amended codes for their environments.
What does NFPA 855 mean for energy storage systems?
NFPA 855 now explicitly ties the “Qualified Person” definition to energy storage systems rather than just generic electrical equipment. The definition emphasizes that a qualified person must have: Safety training to recognize, avoid, and mitigate ESS hazards.
How much battery energy storage has been installed in 2021?
Cumulative Installed Utility-Scale Battery Energy Storage, U.S. As Figure 1 shows, 2021 saw a remarkable increase in the deployment of battery energy storage in the U.S. Twice as much utility-scale battery energy storage was installed in 2021 alone—3,145 megawatts (MW)—than was installed in all previous years combined (1,372 MW) (EIA 2022).
What are energy storage policies?
These policies come in many forms, such as mandates, financial incentives, and new regulations, but they share a common goal of facilitating the deployment of energy storage on the electric grid. In recent years, several states have enacted sweeping energy storage legislation that implements multiple energy storage policies at once (PNNL 2022).
What types of energy storage systems are included
