standards work for people and business
A Global Leader Since 1919 In:
2 Creating a better, safer, more sustainable world where standards work for people and business
Standards
Testing & Certification
Consumer Product Evaluation
• 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
• CSA marks appear on billions of qualified products worldwide
• Tests and certifies products for North America and internationally
• Special Inspections and Field Evaluations
• 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
The Growing ES Market
3 Creating a better, safer, more sustainable world where standards work for people and business
• 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 Each application and battery
technology have different safety and
compliance challenges

Codes and Standards for ESS
4 Creating a better, safer, more sustainable world where standards work for people and business
• 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
The Standards Development Process
5 Creating a better, safer, more sustainable world where standards work for people and business
• 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 ... ...

Certification of ES Systems
6 Creating a better, safer, more sustainable world where standards work for people and business
• 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
Model Certification
7 Creating a better, safer, more sustainable world where standards work for people and business
• 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
Field Evaluation
8 Creating a better, safer, more sustainable world where standards work for people and business
• 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
Overview of SI/FE Process
9 Creating a better, safer, more sustainable world where standards work for people and business
• 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?
Sample of ES Component Standards
10 Creating a better, safer, more sustainable world where standards work for people and business
Sample Documents
IEC 62485-5
Safety requirements for secondary batteries and
battery installations – Part 1-5: Lithium-ion batteries
for stationary applications
IEC 62485-2
Safety requirements for secondary batteries and
battery installations – Part 1-2: Stationary Batteries
(lead-acid and nickel batteries)
IEC 62932 series
(draft)
Flow batteries for stationary applications; General,
performance, and safety requirements
UL 1741
Inverters, converters, controllers, and interconnection
system equipment for use with distributed energy
storage systems
UL1973 Batteries for use in stationary applications and light
electric rail
IEC 61850 Communications networks and management
systems
• Components of the system will
need independent certification
– Battery cells
– Battery pack/module
– Inverter
– Controls, circuit breakers, etc.
Sample of ES System Standards
11 Creating a better, safer, more sustainable world where standards work for people and business
Sample Documents
IEC 62933 Series
(draft)
Electrical Energy Storage Systems: Terminology,
planning and installation, environmental issues, and
safety considerations
UL9540 Safety for energy storage systems and equipment
IEEE 1547 Standard for interconnecting distributed resources
with electric power systems
IEC 60529, IEEE
1357, UL 96A, IBC,
IFC, and NFPA 70
Anchoring and protection from natural disasters
(seismic, flood, etc.) and the elements (rain, snow,
wind, etc.)
ASME TES-1
(draft)
Safety for molten salt thermal energy storage
systems
• 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
Summary
12 Creating a better, safer, more sustainable world where standards work for people and business
• 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
