There are other requirements in IRC Section R328 that are not within the scope of this bulletin. 2021 IRC Section R328.2 states: “Energy storage systems (ESS) shall be listed and labeled in accordance with UL 9540.” UL 9540-16 is the product safety standard for Energy Storage Systems and Equipment referenced in Chapter 44 of the 2021 IRC.
The installation codes and standards cited require a residential ESS to be certified to UL 9540, the Standard for Energy Storage Systems and Equipment, and may also specify a maximum stored energy limitation of 20 kWh per ESS unit.
2021 IRC Section R328.2 states: “Energy storage systems (ESS) shall be listed and labeled in accordance with UL 9540.” UL 9540-16 is the product safety standard for Energy Storage Systems and Equipment referenced in Chapter 44 of the 2021 IRC. The basic requirement for ESS marking is to be “labeled in accordance with UL 9540.”
February 24, 2022 – As we continue moving toward net zero, the need for energy storage systems (ESSs) will continue to rise in both residential and non-residential applications.
The International Residential Code (IRC) and NFPA 855, Standard for the Installation of Stationary Energy Storage Systems, both have criteria for lithium-ion battery energy storage systems (ESSs) intended for use in residential applications. How can I verify that an ESS is certified for residential use?
This restriction in the CE Code is also in contradiction of NFPA 855 “Installation of stationary energy storage systems”. Clause 15.6.1 permits ESSs to be installed in attached and detached garages; in enclosed utility closets, and storage spaces.

The battery energy storage systems industry has witnessed a higher inflow of investments in the last few years and is expected to continue this trend in the future. According to the International Energy Agency (IEA), investments in energy storage exceeded USD 20 billion in 2022.
To generate revenue from battery energy storage systems in Europe, companies need to be strategic and take advantage of different markets and services. Capacity markets, for example, offer a stable source of income: payment is made for the provision of reserve capacity.
China is investing heavily in battery energy storage systems (BESS), targeting 100 GW energy storage capacity by 2030. The 14th FYP set the tone to support all types of BESS, including novel lithium-ion, sodium-ion, lead-carbon, and redox flow.
This imbalance often results in grid instability and compromises power quality. Battery energy storage systems (BESS) store excess renewable energy and discharge the stored energy when it is needed. By mitigating renewable energy fluctuations, BESS can enhance the integration of renewable energy into the grid.
The lithium-ion battery segment is projected to lead the industry and is anticipated to hold a significant market share during the forecast period. Increasing deployment of new large-capacity grid infrastructure, along with continuous technological advancements in Li-ion BESS products, will drive the segment growth.
Recently, in January 2024, the company unveiled plans for ten grid-scale battery storage projects lined up for 2024. Additionally, Samsung SDI, Total, Hitachi, and GE are among the leading players delivering numerous types of advanced energy storage battery systems and solutions.
