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 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).
How many MW of energy storage will utilities install in 2022?
This pace is expected to continue accelerating, as utilities have reported to the Energy Information Administration (EIA) that they are already contracted to install more than 6,100 MW of utility-scale energy storage in 2022 (EIA 2022).
