Energy Storage Safety

› Codes, Standards, and Regulations

Following the DOE energy storage safety workshop, two short-term activities were initiated to foster efforts to address energy storage system safety. One of those was the publication of a document to help with the understanding of codes, standards and regulations development and deployment -- a topic that is somewhat complicated and yet very important to understand no matter what your role is in ESS development and deployment. The other activity is focused on a companion document that will inventory codes, standards and regulations applicable to ESS and experiences to date in securing approval for ESS installations.

  • › Codes 101: Overview of the Processes Associated with the Development and Deployment of Codes, Standards and Regulations in the United States Affecting Energy Storage Systems Safety
    • › Purpose - 

      › The purpose of this document is to acquaint stakeholders and interested parties involved in the development and deployment of energy storage systems (ESS) with the subject of safety codes, standards and regulations (CSR) that can impact their activities. It is hoped that after review of this document, those stakeholders and interested parties will have a more in depth and uniform understanding of safety CSR that can foster improved communications among all ESS stakeholders and foster their working together to realize more timely and appropriate acceptance and approval of safe ESS technology through CSR.

    • › Scope - 

      › This document addresses the manner in which CSR that contain minimum safety requirements applicable to ESS are developed and deployed in the United States. It is recognized that the development and deployment of CSR internationally at the national, regional or global level are also of relevance and interest to the ESS industry and stakeholders and interested parties. The immediate need for this document in supporting the U.S. Department of Energy (DOE) Office of Electricity Delivery and Energy Reliability (OE) ESS Safety Roadmap efforts suggests that the focus for the first version of this document be limited to the United States and extended and enhanced in the future to address international CSR efforts. One exception is the inclusion of U.S. efforts associated with relevant standards development at the global level through the International Electrotechnical Commission (IEC).

  • › Inventory of Codes, Standards and Regulations: Safety-Related Codes and Standards for Energy Storage Systems and Experiences Securing Energy Storage System Approval and Acceptance - 

    › One of the most urgent needs identified at DOE OE Energy Storage Safety Workshop is the need for a standardized body of metrics and criteria that when satisfied effectively support the successful deployment of energy storage systems. The safety related codes, standards and regulations (CSRs) currently available do not provide criteria to specifically address the entire range of ESS technologies or options/scenarios available for ESS installation. This means each system may need to be evaluated for approval on an individual basis by federal, state or local regulatory authorities, utilities and others who are faced with development of their own safety related criteria in the absence of updated CSR upon which to base their review and approval of ESS with respect to safety. The work being conducted to update CSR to more appropriately address ESS can help eliminate what would otherwise be a wide range of variations in the criteria governing the design and construction of energy storage systems and the manner in which they must be installed. The availability of a uniform, cohesive and up to date set of CSR to address ESS safety can help in reducing ESS costs and streamline system deployment.

    • › Purpose - 

      › The purpose of this document is to identify laws, rules, codes, standards, regulations (CSR) and associated requirements related to safety that could apply to stationary energy storage systems (ESS) and experiences to date securing approval of ESS from those who have adopted and are applying CSR. This information is intended to assist in securing approval of ESS under current CSR and to foster the updating, revision and enhancement of CSR to foster timelier and appropriate approval of ESS with respect to safety.

    • › Scope - 

      › This document contains three separate but interrelated areas of focus.

      • › Current CSR documents that could apply to ESS have been identified, the scope of each document is presented, and areas in those CSR that might need revision and relevant thoughts about moving forward to revise and/or apply the document are presented.
      • › Experiences securing approval of ESS under current CSR are provided and details associated with the information and documentation needed to secure approval of ESS is available along with any challenges associated with the approval.
      • › Information needed to secure the approval of an ESS application on the basis of equivalency with current CSR that may not specifically address the intended ESS technology is available to guide approval of ESS under current CSR.
