February 28th, 2017

2. Agenda NEMA standards activities
Measuring Energy Storage System Performance
Secretariat for the ANSI Accredited Storage Committee (ASC) on Energy Storage Systems
IEC TC120 (Electrical Energy Storage Systems)
National Fire Protection Association (NFPA) Technical Committee
Installation standard for Stationary Energy Storage Systems

3. NEMA Standards Activities
Measuring Energy Storage System Performance
Background
Lack of a uniform and repeatable method for determining and expressing system performance
Project initiated under the DoE Energy Storage Systems program
Development of a protocol/pre-standard for immediate use and a basis for US and International standards
NEMA was an interested stakeholder and actively participated in the process.

4. NEMA Standards Activities
Measuring Energy Storage System Performance
Timeline
November st version of the protocol completed (2 applications, 7 performance metrics)
June nd version completed (added 1 more application, some enhancements to existing provisions)
April rd version completed (added 5 more applications, more metrics, format revised)
References: R.pdf

7. NEMA Standards Activities
Secretariat for the ANSI Accredited Standards Committee (ASC) on Energy Storage Systems
ANSI fundamental standards development requirements:
Openness
Lack of dominance
Balance
Consideration of views and objections
Consensus vote
ASC on Energy Storage Systems taking the Energy Storage System Performance protocol and converting into an ANSI/NEMA standard

8. International Electrotechnical Commission (IEC)
IEC develops standards for all electrical, electronic, and related technologies
Home page:
Each IEC standard is developed by working groups in a technical committee (TC)
Each country has its own technical advisory group (TAG) (sometimes called mirror committee) associated with a TC

9. IEC TC-120-Electrical Energy Storage (EES) Systems
Standardization in the field of grid integrated EES Systems
EES System aspects rather that the energy storage devices
Investigates the need for new standards for EES Systems
Grid includes: Transmission, Distribution, Commercial, Industrial, Residential, and Islanded
EES Systems that can both store and provide electrical energy

10. IEC TC-120 Working Groups WG1- Terminology
WG2- Unit parameters and testing methods
WG3- Planning and installation
WG4- Environmental issues
WG5- Safety considerations
NEMA holds the secretariat for the US TAG

11. IEC TC-120 Liaisons to other IEC TCs
