Compliance Requirements for Energy Storage Systems in North America Jim Green Global Business Manager, Energy Storage Creating a better, safer, more sustainable world where standards work for people and business 1
A Global Leader Since 1919 In: Standards Develops standards for the U.S. and Canada; Over 3,000 standards and codes in 54 technology areas 1,300 technical committees; 9,000 engaged, dedicated volunteer members Provides standards-based training across a range of industries Testing & Certification CSA marks appear on billions of qualified products worldwide Tests and certifies products for North America and internationally Special Inspections and Field Evaluations Consumer Product Evaluation Conducts energy efficiency and performance evaluation services Helps streamline the entire product development cycle Works closely with manufacturers, importers, distributors and major retailers 39 Offices in 16 Countries including India 2
The Growing ES Market Battery based Energy Storage Systems are a rapidly growing market across 3 main segments: Residential Typically < 10 kwh Commercial/Industrial Typically < 500 kwh Utility/Community scale Typically > 500 kwh Three primary battery types dominate the market: Lithium-ion Lead acid Flow Batteries Source: Navigant Research Each application and battery technology have different safety and compliance challenges 3
Codes and Standards for ESS Market and technology growth is outpacing standard development and code upgrades US and Canadian electric codes are evolving: US NEC section 706 added to address ESS Canadian CEC Sections 26 & 64 reference batteries for ES US Department of Energy is actively supporting development Strategic plan on ESS Safety Pacific Northwest National Lab Sandia National Lab 4
The Standards Development Process Involvement in your local and international standards development provides significant benefits Have a voice in standard requirements Gain early access to draft standards and test requirements The Canadian example Canadian Mirror Committee managed by CSA develops the position for Canada Drives international development through IEC Canada will ultimately adopt IEC standards SCC CSA Canada Canadian Energy Storage Mirror Committee CAN IEEE IEC Technical Committee IEC TC 120 International...... USA Recommended Practices ASME...... 5
Certification of ES Systems Each component will bear a certification mark Battery Inverter Controls Others such as PV modules Overall system will then be approved via two common methods Model Certification Field Evaluation or Inspection 6
Model Certification Typically used for high volume applications such as residential applications for energy storage Requires a follow-up factory inspection process to ensure products are being made to the certified design Bears a certification mark from a recognized, accredited certification body A residential energy storage system used to store PV energy may require model certification and carry a certification mark 7
Field Evaluation Used for low volume installations such as commercial applications for energy storage (<500 per year in Canada for example) Two programs in North America US Field Evaluation (USFE) in the USA a voluntary program based on local authority requirements Special Inspection (SI) in Canada mandatory for non-certified products A commercial energy storage system may require field evaluation and carry a SI label in Canada or USFE label in the USA 8
Overview of SI/FE Process Review certification or testing documents for critical components prior to inspection Battery, Inverter, etc. Functional Safety review of software may be required Inspect installation to confirm code compliance, may conduct some testing Confirm installed components match certifications Confirm environmental requirements Ventilation, Enclosure, Foundation, Site protection, etc. Apply SI/FE label and issue report Will India implement a similar field evaluation program for Energy Storage installation approval? 9
Sample of ES Component Standards Components of the system will need independent certification Battery cells Battery pack/module Inverter Controls, circuit breakers, etc. Sample Documents IEC 62485-5 IEC 62485-2 IEC 62932 series (draft) UL 1741 UL1973 IEC 61850 Safety requirements for secondary batteries and battery installations Part 1-5: Lithium-ion batteries for stationary applications Safety requirements for secondary batteries and battery installations Part 1-2: Stationary Batteries (lead-acid and nickel batteries) Flow batteries for stationary applications; General, performance, and safety requirements Inverters, converters, controllers, and interconnection system equipment for use with distributed energy storage systems Batteries for use in stationary applications and light electric rail Communications networks and management systems 10
Sample of ES System Standards System-based standards now becoming more popular IEC very active with a series of draft ES standards nearing publication Installation considerations also covered by many standards System standards may include additional evaluations: Functional safety of software Cyber security Failure mode and effects analysis Sample Documents IEC 62933 Series (draft) UL9540 IEEE 1547 IEC 60529, IEEE 1357, UL 96A, IBC, IFC, and NFPA 70 ASME TES-1 (draft) Electrical Energy Storage Systems: Terminology, planning and installation, environmental issues, and safety considerations Safety for energy storage systems and equipment Standard for interconnecting distributed resources with electric power systems Anchoring and protection from natural disasters (seismic, flood, etc.) and the elements (rain, snow, wind, etc.) Safety for molten salt thermal energy storage systems 11
Summary Standards development is complicated but very important to future manufacturing and ES growth Get involved in technical committees and local industry groups like IESA Seek help from an accredited certification body India is a major player in the global growth of ES According to Customized Energy Solutions, the India market for ES will grow from about 20,000 MWh in 2016 to over 60,000 MWh by 2022 Driving towards harmonization with international standards will help India s ES efforts grow 12
