This Compliance Guide (CG) covers the design and construction of stationary energy storage systems (ESS), their component parts and the siting, installation, commissioning, operations, maintenance, and repair/renovation of ESS within the built environment with evaluations of those ESSs against voluntary sector standards and model codes that have been published and adopted as of the publication date of this CG.
Energy Storage System and Component Standards 2. If relevant testing standards are not identified, it is possible they are under development by an SDO or by a third-party testing entity that plans to use them to conduct tests until a formal standard has been developed and approved by an SDO.
Until existing model codes and standards are updated or new ones developed and then adopted, one seeking to deploy energy storage technologies or needing to verify an installation's safety may be challenged in applying current CSRs to an energy storage system (ESS).
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 system deployment.
The 2017 NEC is likely to replace references to ESS installation in Article 480 and has proposed a new Article 706 Energy Storage Systems that consider the application of electrochemical energy storage along with other types of energy storage that are referenced in other Articles within the code (e.g., PV, Wind, etc.)
It is recognized that electric energy storage equipment or systems can be a single device providing all required functions or an assembly of components, each having limited functions. Components having limited functions shall be tested for those functions in accordance with this standard.
Safety standard for stationary batteries for energy storage applications, non-chemistry specific and includes electrochemical capacitor systems or hybrid electrochemical capacitor and battery systems. Includes requirements for unique technologies such as flow batteries and sodium beta (i.e., sodium sulfur and sodium nickel chloride).
In today's market, the installed cost of a commercial lithium battery energy storage system — including the battery pack, Battery Management System (BMS), Power Conversion System (PCS), and installation — typically ranges from: $280 to $580 per kWh for small to medium-sized commercial projects.
Around the beginning of this year, BloombergNEF (BNEF) released its annual Battery Storage System Cost Survey, which found that global average turnkey energy storage system prices had fallen 40% from 2023 numbers to US$165/kWh in 2024.
Energy storage system costs for four-hour duration systems exceed $300/kWh for the first time since 2017. Rising raw material prices, particularly for lithium and nickel, contribute to increased energy storage costs. Fixed operation and maintenance costs for battery systems are estimated at 2.5% of capital costs.
As we look ahead to 2024, energy storage system (ESS) costs are expected to undergo significant changes. Currently, the average cost remains above $300/kWh for four-hour duration systems, primarily due to rising raw material prices since 2017.
The long-term cost outlook for energy storage systems looks promising, with substantial reductions in capital expenditures expected over the next decade. For a 60MW 4-hour battery system, CAPEX reductions range from 18% to 52% between 2022 and 2035, depending on the scenario.
Around the beginning of this year, BloombergNEF (BNEF) released its annual Battery Storage System Cost Survey, which found that global average turnkey energy storage system prices had fallen 40% from 2023 numbers to US$165/kWh in 2024.
Energy storage systems (ESS) for four-hour durations exceed $300/kWh, marking the first price hike since 2017, largely driven by escalating raw material costs and supply chain disruptions. Geopolitical issues have intensified these trends, especially concerning lithium and nickel.
A comprehensive understanding of energy storage costs is essential for effectively navigating the rapidly evolving energy landscape. This landscape is shaped by technologies such as lithium-ion batteries and large-scale energy storage solutions, along with projections for battery pricing and pack prices.

Let's analyze the numbers, the factors influencing them, and why now is the best time to invest in energy storage. $280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels. For large containerized systems (e.g., 100 kWh or more), the cost can drop to $180 - $300 per kWh.
Informing the viable application of electricity storage technologies, including batteries and pumped hydro storage, with the latest data and analysis on costs and performance. Energy storage technologies, store energy either as electricity or heat/cold, so it can be used at a later time.
This study shows that battery electricity storage systems offer enormous deployment and cost-reduction potential. By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials.
Small-scale lithium-ion residential battery systems in the German market suggest that between 2014 and 2020, battery energy storage systems (BESS) prices fell by 71%, to USD 776/kWh.
Additional storage technologies will be added as representative cost and performance metrics are verified. The interactive figure below presents results on the total installed ESS cost ranges by technology, year, power capacity (MW), and duration (hr).
A standard 100 kWh system can cost between $25,000 and $50,000, depending on the components and complexity. What are the costs of commercial battery storage? Battery pack - typically LFP (Lithium Uranium Phosphate), GSL Energy utilizes new A-grade cells.
Nairobi, Kenya – July 2025 — The Kenya Electricity Generating Company (KenGen) has officially commissioned its first Battery Energy Storage System (BESS) to power a modular data center in Nairobi, marking a major milestone in the country's clean energy transition. key driver for economic growth.

The 'private wires' policy, as it is known, is designed to alleviate current strain on Ireland's national grid by encouraging companies with high energy loads to invest in separate grid connections for their own on-site renewable energy generation projects in wind, solar, and storage.
The policy framework is a first of kind policy, which clarifies the key role of electricity storage in Ireland's transition to an electricity-led system, supporting Irelands 2030 climate targets, it may be considered as a steppingstone on Ireland's path to net zero carbon emissions.
The policy sets out 10 policy actions, which include the following proposed key actions: Electricity storage system operators are to be given access to all wholesale electricity markets in Ireland.
In a bid to incentivise the creation of energy storage in Ireland, the government is developing a policy framework to help deliver their objectives in this area of its Climate Action Plan which is targeting a proportion of renewable electricity to up to 80% by 2030.
In this regard, greater emphasis is placed on ensuring 'long duration' electricity storage systems – systems that have the capacity to deliver electricity throughout at least a four-hour period – are integrated into Ireland's electricity grid.

This might be when demand is high or when capacity from wind or solar is low – for instance, during a low pressure period in winter. Ireland has about 800MW of storage capacity, while the policy framework recommends procuring additional storage immediately. Ultimately, this will provide cheaper, green electricity to the consumer.
Installation of the 60-megawatt diesel-powered generation plant was completed on Monday. The plant, which will cost taxpayers €37 million, is expected to remain in operation until a second undersea interconnector linking Malta to the European power grid is completed.
