2022 BUILDING ENERGY EFFICIENCY STANDARDS

IEC Standards for Energy Storage Systems
IEC 62933-1:2024 defines terms applicable to electrical energy storage (EES) systems including terms necessary for the definition of unit parameters, test methods, planning, installation, operation. [pdf]FAQS about IEC Standards for Energy Storage Systems
What is the energy storage standard?
The Standard covers a comprehensive review of energy storage systems, covering charging and discharging, protection, control, communication between devices, fluids movement and other aspects.
Are energy storage codes & standards needed?
Discussions with industry professionals indicate a significant need for standards ” [1, p. 30]. Under this strategic driver, a portion of DOE-funded energy storage research and development (R&D) is directed to actively work with industry to fill energy storage Codes & Standards (C&S) gaps.
What are the IEC technical committees preparing international standards for EES?
Several IEC technical committees (TCs) prepare international standards relevant to EES: The need for electrical energy storage (EES) will increase significantly over the coming years. With the growing penetration of wind and solar, surplus energy could be captured to help reduce generation costs and increase energy supply.
Does industry need standards for energy storage?
As cited in the DOE OE ES Program Plan, “Industry requires specifications of standards for characterizing the performance of energy storage under grid conditions and for modeling behavior. Discussions with industry pro-fessionals indicate a significant need for standards” [1, p. 30].
What safety standards affect the design and installation of ESS?
As shown in Fig. 3, many safety C&S affect the design and installation of ESS. One of the key product standards that covers the full system is the UL9540 Standard for Safety: Energy Storage Systems and Equipment . Here, we discuss this standard in detail; some of the remaining challenges are discussed in the next section.
What does the IEC recommend?
The IEC therefore recommends regulators to achieve the conditions for all necessary cooperation between the energy markets in electricity and gas, including use of infrastructure. The IEC recommends policy-makers to make the encouragement of storage deployment a public policy goal.
