6 FAQs about National grid energy storage acceptance standards

Are energy storage systems compliant?

Energy storage systems continue to be a rapidly evolving industry. Thus, the key to safe and up-to-date compliance requirements involves the adoption and application of codes and standards in addition to the development or writing of codes and standards.

Does industry need energy storage standards?

As cited in the DOE OE ES Program Plan, “Industry requires specifications of standards for characterizing the performance of energy storage under grid conditions and for modeling behavior. Discussions with industry professionals indicate a significant need for standards ” [1, p. 30].

Do grid energy storage systems generate electricity?

Grid energy storage systems are “enabling technologies”; they do not generate electricity, but they do enable critical advances to modernize and stabilize the electric grid.

What's new in energy storage safety?

Since the publication of the first Energy Storage Safety Strategic Plan in 2014, there have been introductions of new technologies, new use cases, and new codes, standards, regulations, and testing methods. Additionally, failures in deployed energy storage systems (ESS) have led to new emergency response best practices.

What is National Grid ESB?

A distribution or sub-transmission line owned by National Grid (which is presently interconnected to a third-party energy supplier or generating facility selling power into the wholesale market) for the purpose of selling power into the wholesale market. This ESB also addresses state-specific requirements pertaining to parallel generators.

Are energy storage codes & standards needed?

Discussions with industry professionals indicate a significant need for standards ” [1, p. 30]. Under this strategic driver, a portion of DOE-funded energy storage research and development (R&D) is directed to actively work with industry to fill energy storage Codes & Standards (C&S) gaps.
