First Quarter M&A Activity Tops $2.3B for Energy Storage Companies: Mercom Capital

Investment focus is broadening from traditional battery storage to include materials, recycling, and integrated systems, as the industry aims to meet the IEA's projected capacity of over 1,200 GW by 2030 and 5 TW by 2050.

Merger and acquisition (M&A) activity for companies across the energy storage value chain rose slightly to $2.3 billion in the first quarter, according to research by Mercom Capital Group.

The corporate, venture capital and debt financing movement totaled 38 deals in the first three months of 2026. Mercom Capital Group reported a 5% increase year-over-year, compared to 31 deals and $2.2 billion of M&A in the first quarter of 2025.

Venture capital investment accounted for $1.2 billion in 2026's overall first quarter energy storage M&A investment, also $100 million more than the same period last year. The data shows that capital across the energy sector for more companies is slowly expanding, helping the industry push forward on global production to manufacture energy storage systems.

Some of the top deals within that $2.3 billion total included California-based energy storage company EnerVenue Holdings ($300 million), Switzerland-based energy provider Terralayr ($223 million), and Denver-based developer and operator Liminal Energy ($200 million). 

Mercom Capital pointed out that the downstream side of energy storage value chain attracted the most VC funding in the shift to renewable energy, a group which includes battery cell manufacturing, assembly, installation and even behind-the-meter solutions. Some energy storage investment is shifting beyond batteries to hydropower, biofuels and hydrogen, according to reports.

Other leading categories Mercom highlighted included energy storage systems (ESS), materials & components providers, and battery recycling companies. The Mercom Capital Group focuses on clean energy markets in the U.S., Europe, India, and the Middle East.

Corporate mergers and acquisitions of energy storage companies in Q1 2026 increased to seven deals, compared to only one in Q1 of the prior year. Those seven acquisitions included downstream platforms, battery technologies and materials, Mercom stated.

The firm added that 7.2 GW of energy storage projects were acquired in Q1 2026, a 227% increase compared to Q1 of the prior year. The increase in these project acquisitions comes as the International Energy Agency (IEA) projects global installed capacity of battery storage may rise from less than 200 GW in 2023 to 1,200 GW by 2030.

Eventually, IEA states that it will need to reach more than 5 terawatts (TW) by 2050 to meet net-zero targets.

To achieve this, IEA says that battery storage deployment must continue to increase by 25% per year on average, adding that batteries are a key transition away from fossil fuels and help accelerate energy efficiency.

Battery storage is now being incorporated with gas-fired power in new data center projects. The reason is that batteries are capable of dealing with transient load swings, where load can fluctuate wildly in sub-seconds that gas turbines aren’t designed for.
