As Energy-Storage.news reported last month, global prices for battery energy storage systems (BESS) have been on a downward trend since early 2023, having shot up in 2022. We heard from delegates at the Energy Storage Summit EU in London last month about the implications of falling BESS prices.
In 2025, China made a couple of major political moves affecting its energy storage sector. In late November, the Ministry of Industry and Information Technology (MIIT) pledged to accelerate the rollout of targeted policies aimed at curbing “irrational competition” in the power and battery energy storage industry.
In another record-breaking year for energy storage installations, the sector has firmly cemented its position in the global electricity market and reached new heights. From price swings and relentless technological advancements to shifting policy headwinds and tailwinds, 2025 proved to be anything but uneventful.
Battery energy storage technology suppliers have continued their relentless R&D efforts, delivering remarkable progress in both energy density and modularity. With energy density being a critical factor for unit economics, utility-scale systems have evolved rapidly.
Private equity and venture capital investments in the battery energy storage system, energy management and energy storage sector so far in 2024 have exceeded 2023's levels and are on pace to reach one of the highest annual totals in five years.
The industrial sector secured the most battery energy storage system deals, followed closely by the energy and utility sector. In the largest transaction, battery storage company NineDot Holdings Inc. raised $225 million in a round of funding led by Manulife Investment Management Ltd., with participation from existing backer The Carlyle Group Inc.
"The major driving force behind this investment trend is the market itself," Mani said, citing growth in electric vehicles, increased demand from AI-driven datacenters and a growing recognition of battery energy storage systems in addressing renewable energy needs.
Global energy storage installations are projected to grow by 76% in 2025, reaching 69 GW/169 GWh, driven by surging electricity demand, especially from electric vehicle adoption and data center expansion. The latter alone is expected to account for 44% of U.S. electricity load growth through 2028.
