The Battery Energy Storage System Market will be valued at USD 18.5 billion in 2025. As per FMI's analysis, the battery energy storage system will grow at a CAGR of 11.1% and reach USD 65.3 billion by 2035. The world battery energy storage system (BESS) industry experienced growth acceleration in 2024, fueled by growing grid instability, mounting renewable energy integration, and policy initiatives.
The USA and China were at the forefront of deployments, with China ramping up its utility-scale storage initiatives to underpin its 2060 carbon neutrality targets. The USA Inflation Reduction Act (IRA) accelerated investments in local battery production and storage initiatives, while Europe concentrated on grid resilience in the face of energy security issues.
Lithium-ion batteries continued to lead, but other chemistries (e.g., sodium-ion, flow batteries) found acceptance through supply chain diversification. Commercial and industrial (C&I) storage demand boomed as companies needed backup power and energy cost savings. Developing economies in Asia-Pacific and Africa witnessed rising microgrid installations, with the help of falling battery prices.
2025 and Beyond
The BESS industry will increase at an 11.1% CAGR to reach USD 65.3 billion by 2035, led by:
Challenges are raw material price uncertainty and regulatory delays. But with increasing energy demand and decarbonization pressures, BESS will continue to be an indispensable enabler of the global energy transition.

Secure Supply Chains & Diversify Battery Chemistries
Action: Invest in local raw material sourcing (lithium, cobalt substitutes) and dual-supply techniques to counter geopolitical threats. Give top priority to R&D in sodium-ion, solid-state, and LFP batteries to lower cost and reliance on key minerals.
Position Ourselves with Policy-Driven Demand Hotspots
Action: Target industries with robust regulatory tailwinds (USA IRA tax incentives, EU Battery Passport, China's storage requirements). Create policy-savvy product strategies, like recyclable batteries for Europe or low-cost storage for new Asia.
Construct Hybrid Solutions & Energy-as-a-Service Models
Action: Partner with renewable developers, utilities, and tech companies to provide solar storage microgrids, virtual power plants (VPPs), and leasing models. Make software/AI startup acquisitions to advance grid optimization and battery life cycle management.
| Risk | Probability/Impact |
|---|---|
| Geopolitical Supply Chain Disruptions (e.g., lithium/cobalt shortages, trade restrictions) | High/Severe - Could delay projects, inflate costs, and force abrupt chemistry shifts. |
| Regulatory Uncertainty (e.g., shifting subsidies, slow permitting, safety standards) | Medium-High/High - May stall deployments in key players (EU, USA) or invalidate existing designs. |
| Technology Displacement (e.g., rapid rise of sodium-ion/solid-state outcompeting lithium-ion) | Medium/High - Could strand assets or erode margins for lagging players. |
| Priority | Immediate Action |
|---|---|
| Secure Alternative Battery Material Supply | Finalize contracts with 2+ sodium-ion or LFP battery suppliers to diversify away from lithium dependence. |
| Align with IRA/EU Subsidy Deadlines | Launch a dedicated task force to fast-track 3 USA or EU storage projects eligible for 2024 tax credits. |
| Pilot Energy-as-a-Service Model | Partner with 1 regional utility to test leased storage/VPP solutions (launch within 6 months). |
To stay ahead, companies must leverage the USD 65B battery storage boom, we suggest an immediate shift to policy-driven industries (USA/EU subsidies) hedging supply chain bets through dual sourcing (sodium-ion + LFP). Within 12 months, begin at least one Energy-as-a-Service pilot (e.g., storage leasing with a renewable developer) securing sticky revenue before commoditization. This insight requires restyling your 2025 roadmap to focus on:
Localized production (to access IRA/EU incentives),
R&D collaborations on non-lithium chemistries, and
M&A of grid-edge software companies to support VPPs.
Differentiator: While others pursue lithium-ion scale, this strategy makes you the nimble, policy-aware leader in command of both margins and industries. Act quickly-regulatory windows and first-maker benefits are shutting rapidly.
Lithium-ion (Li-ion) batteries are the most popular technology in battery energy storage systems (BESS) today owing to their efficiency, high energy density, and decreasing costs. They have captured grid-scale, residential systems, and all-in-between applications since they provide faster response times, longer lifetimes (5,000+ cycles), and modular scalability, which fits well in renewable energy integration and peak shaving applications.
Although newer lead-acid batteries are less expensive to purchase upfront, their lower lifespan and less efficient discharge restrict them to limited applications such as backup power. Flow batteries, while promising for long-duration storage (8+ hours), are still expensive and complicated, limiting them to specialized grid applications.
On-grid battery energy storage systems (BESS) are much more prevalent than off-grid systems, mainly due to their support for renewable energy integration, grid stabilization, and peak load management in utility-scale and commercial/industrial uses.
They are connected to the electrical grid directly, enabling them to offer frequency regulation, demand charge reduction, and backup power during outages-making them a necessity for contemporary energy industries. Government subsidies (e.g., USA IRA tax credits, EU capacity industries) and declining lithium-ion battery prices have further boosted on-grid BESS adoption.
Utility-owned battery energy storage systems (BESS) are the most common in use, with industry leadership based on scale, grid balancing, and access to capital. Utilities use large-scale BESS for peak shaving, renewable integration, and grid reliability, with regulatory frameworks and rate recovery mechanisms supporting them. Their business model is compatible with centralized energy infrastructure, positioning them as leaders in the transition to cleaner grids.
Customer-sited BESS (commercial/residential) is expanding strongly, particularly where net metering exists, as do solar incentives like California's SGIP and increasing electricity costs. Behind-the-meter storage is acquired by consumers for energy autonomy, backup, and bill savings but is slowed by the requirement of high capital expense upfront.
Battery energy storage systems (BESS) within the 100-500 MWh range are presently the most extensively installed since this capacity presents an ideal blend of grid-scale capability and economic feasibility. The mid-size arrays are substantial enough to accommodate utility applications such as renewable integration, peak shaving, and frequency response, yet sufficiently affordable to enable and locate with respect to immense 500+ MWh endeavors. Their modular design enables scalable flexibility to accommodate regional grid requirements, making them perfect for ISO industries, solar/wind farms, and commercial/industrial consumers.
Below 100 MWh applications are mainly for behind-the-meter commercial storage, microgrids, and residential aggregation (VPPs), but their small size constrains revenue opportunities from grid services. Above 500 MWh projects-albeit increasing-have longer development lead times, complicated interconnection procedures, and more expensive financing barriers, limiting them to flagship projects in well-supported industries (e.g., California, Australia).
Front-of-the-meter (FTM) battery energy storage installations are now more prevalent than behind-the-meter (BTM) installations, chiefly because of the direct contribution that FTM provides to grid support, renewable energy integration, and wholesale industry opportunities.
FTM installations-standard utility-scale ones-are favored through regulatory requirements, capacity payments, and economies of scale and, therefore, become appealing for both utilities and independent power producers. Others, such as the USA (PJM, CAISO), Australia, and the UK, have paced FTM growth with policies designed to encourage wholesale-scale storage in frequency regulation, peak shaving, and transmission deferral.
Utility-scale battery energy storage systems (BESS) are by far the most extensively installed type, representing the largest portion of installed capacity around the world. Large-scale projects (usually 10+ MW) prevail since they directly provide essential grid needs such as integration of renewable sources, peak load management, and frequency regulation.
Utilities and independent power producers include them because economies of scale prevail, government regulation (e.g.,USA state-level storage targets, EU Clean Energy Package), and revenue streams through wholesale electricity industries.
