“Energy storage companies saw their highest VC funding in 2023, largely thanks to the Inflation Reduction Act’s Investment Tax Credit and other incentives like manufacturing credits for battery components. Despite this positive trend, M&A activity lagged due to high asset valuations, elevated interest rates, and investor caution,” said Raj Prabhu, CEO of Mercom Capital Group.

However, corporate funding in the Energy Storage sector, including VC/PE funding, decreased 28% YoY, with $19 billion raised in 120 deals compared to $26.4 billion raised in 124 deals in 2022. LG Energy Solution’s one-off $10.7 billion IPO in 2022 significantly inflated the total funding for that year.
