CSA TS-888:26

Description

Preface This is the first edition of CSA TS-888, Guideline for the installation and energy performance commissioning of residential behind-the-meter battery energy storage systems . This Technical Specification (referred to as “this Document” from here on) provides guidance to support the installation and energy performance commissioning of residential behind-the-meter battery energy storage systems (BESS) by consolidating applicable standards, codes, and best practices, referencing international approaches where appropriate, and highlighting jurisdictional variations across Canada to support safe, consistent, and effective residential BESS deployment. This Document is not a consensus product; that is, it is not a Standard and it has not been formally approved by a CSA Technical Committee. CSA Group acknowledges that the development of this Document was made possible, in part, by the financial support of BC Hydro, Hydro-Québec, Hydro-Québec (Tech Solutions), Independent Electricity System Operator (IESO), Nova Scotia Department of Energy, Efficiency Nova Scotia, and the Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs du Québec (MELCCFP). This Document was prepared by the Subcommittee on Guideline for Residential Battery Energy Storage Systems. Scope 1.1 General This Document provides a guideline to support the installation and energy performance commissioning of residential behind-the-meter battery energy storage systems (BESS). This Document is intended to support interested parties including, but not limited to, system designers, installers, inspectors, and homeowners, by providing guidance on the proper installation of BESS in residential behind-the-meter installations. This Document is intended to reference the different requirements across the Canadian provinces and territories for residential behind-the-meter BESS installations and provide guidance for specifications that are not covered under these requirements. 1.2 Inclusions This Document applies to stationary BESS in residential applications, covering both AC- and DC-coupled systems with stand-alone or hybrid configurations using lithium-ion and other commonly used battery chemistries. This Document is intended to be used for the following: a) pre-installation procedures: i) site assessment; ii) system sizing and selection, with considerations for on-site photovoltaic (PV) installations; and iii) permits and regulations checklist; b) installation procedures: i) electrical installation; ii) mechanical installation; and iii) equipment listing; c) commissioning procedures: i) energy performance pre-commissioning checks and initial checks; ii) performance evaluation testing; and iii) documentation and reporting; and d) post-installation procedures: i) hand-over and user training; ii) operating procedures; iii) maintenance and inspection; iv) repair and troubleshooting; and v)decommissioning. 1.3 Exclusions This Document does not provide requirements for the following: a) fire and safety requirements covered under the Canadian Electrical Code (CE Code), Parts I and II as well as the National Building Code of Canada (NBC) (this Document will cross-reference the applicable standards and codes that are required in the different Canadian jurisdictions); b) construction and marking requirements; c) commercial, institutional, or industrial installations; d) utility-scale or front-of-the-meter installations; e) mobile applications; and f) uninterruptible power supply integrations. 1.4 Terminology In this Document, “should” is used to express a recommendation or that which is advised but not required and “may” is used to express an option or that which is permissible within the limits of the Document.
