The third edition of the UL 9540 Standard for Safety for Energy Storage Systems and Equipment, published in April 2023, introduces replacements, revisions and additions to the requirements for syst.
These requirements cover energy storage systems that are intended to receive and store energy in some form so that the energy storage system can provide electrical energy to loads or to the local/area electric power system (EPS) when needed.
The Standard covers a comprehensive review of energy storage systems, covering charging and discharging, protection, control, communication between devices, fluids movement and other aspects.
Research offerings include: UL can test your large energy storage systems (ESS) based on UL 9540 and provide ESS certification to help identify the safety and performance of your system.
Individual parts (e.g. power conversion system, battery system, etc.) of an energy storage system are not considered an energy storage system on their own. This standard evaluates the compatibility and safety of these various components integrated into a system. Please first log in with a verified email before subscribing to alerts.
The types of energy storage covered under this standard include electrochemical, chemical, mechanical and thermal. The energy storage system shall be constructed either as one unitary complete piece of equipment or as matched assemblies, that when connected, form the system.

The National Electrical Code (NEC) Section 690 outlines specific labeling requirements for photovoltaic (PV) systems to ensure safety and compliance. These requirements were updated in 2020.
The National Electrical Code (NEC) Section 690 outlines specific labeling requirements for photovoltaic (PV) systems to ensure safety and compliance. These requirements were updated in 2020. Visibility After Installation: Labels or markings must remain visible after installation, ensuring they can be easily read during maintenance or emergencies.
Added one new label for PV systems floating on bodies of water. The NEC2023 second draft meeting was concluded in October 2021. As PV and wind systems evolve, required labeling will continue to evolve with them. Always check local codes before defining labeling formats.
Many solar builders choose to design and label their installations based on the latest code revisions. Taking into account local AHJ requirements, why would any company want to label to the latest NEC revision? The easy answer is safety, but new technologies also play a part.
The fastening requirement (E) is also moved to 705.30 (E). Finally, the dc voltage label formally in Article 690.53 was moved to 690.7 (D) to correlate the label requirement with the relevant section of code to increase usability.
This is required for safety purposes to clearly indicate the maximum voltage to servicing personnel for PPE and tool selection. Since some PV equipment, such as certain inverters, may have multiple DC circuit inputs, the highest value present in the system shall be used on the single label.
Some municipalities require Maximum ESS DC Voltage, so this has been added to the label by HellermannTyton. In the NEC 2020 Code, MAXIMUM ESS DC VOLTAGE ADDED. The labeling in 706(D)(1-4) shall not be required if an arc-flash label is applied in accordance with accepted industry practice.

In 2025, the global average price of a turnkey battery energy storage system (BESS) is US$117/kWh, according to the Energy Storage Systems Cost Survey 2025 from BloombergNEF (BNEF), published last week (10 December). That was a 31% decline from 2024 numbers. While the pace of price decreases. China's latest large-scale battery energy storage cell procurement has established new pricing benchmarks for both ≥314Ah and ≥500Ah lithium iron phosphate (LFP) cells. This was driven by overcapacity in China, fierce competition, and the widespread adoption of cost-effective.
BloombergNEF's LCOE report shows four-hour battery storage costs fell 27% to $78/MWh in 2025, a record low since 2009, driven by lower pack prices and design advances, while solar and wind LCOEs rose due to supply and regulatory challenges. BNEF's global benchmark costs for solar, onshore wind and offshore wind costs all rose in. Ember provides the latest capex and Levelised Cost of Storage (LCOS) for large, long-duration utility-scale Battery Energy Storage Systems (BESS) across global markets outside China and the US, based on recent auction results and expert interviews. All-in BESS projects now cost just $125/kWh as. Lithium-ion battery prices dropped again in 2025, with average prices coming down 8% to $108 per kilowatt-hour, according to BloombergNEF's annual price survey. This is due to a. Battery energy storage costs have reached a historic turning point, with new research from clean energy think tank Ember revealing that storing electricity now costs just $65 per megawatt-hour (MWh) in global markets outside China and the United States. According to BloombergNEF's Levelized Cost of Electricity.
