Energy Storage

Venture capital (VC/PE) funding in Energy Storage in 2023 was the highest ever recorded, with $9.2 billion in 86 deals.

“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.

Corporate funding in the Energy Storage sector came to $19 billion raised in 120 deals.

Corporate funding for Energy Storage companies in Q4 2023 totaled $3.7 billion in 26 deals.
