FAQs 6

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 an energy storage system (ESS)?

Covers an energy storage system (ESS) that is intended to receive and store energy in some form so that the ESS can provide electrical energy to loads or to the local/area electric power system (EPS) when needed. Electrochemical, chemical, mechanical, and thermal ESS are covered by this Standard.

Can energy storage be used as a temporary source of power?

However, energy storage is increasingly being used in new applications such as support for EV charging stations and home back-up systems. Additionally, many jurisdictions are seeing increasing use of EVs and mobile energy storage systems which are moved around to be used as a temporary source of power.

What is a typical energy storage deployment?

A typical energy storage deployment will consist of multiple project phases, including (1) planning (project initiation, development, and design activities), (2) procurement, (3) construction, (4) acceptance testing (i.e., commissioning), (5) operations and maintenance, and (6) decommissioning.

What makes a good energy storage management system?

The BMS should be resistant to any electromagnetic interference from the PCS (power conversion system) and must be able to cope with current ripple without nuisance warnings and alarms. Interoperability is achieved between the BMS, PCS controller, and energy storage management system with proper integration of communications.

Are energy storage systems dangerous?

The high energy levels in energy storage systems make them especially dangerous if they are not installed and maintained per Code.
