“Some of the funding activity shifted from venture capital and private equity to public market and debt financing in 2022,” said Prabhu. “Last year’s VC numbers skewed higher by just two companies raising over almost $5 billion combined.”

The top VC-funding deals in 2022 included Eolian, which raised $925 million, Form Energy which raised $450 million, and Group14 Technologies, which secured $400 million, followed by Ascend Elements and Hydrostor, which raised $300 million and $250 million, respectively.

Last year, the debt and public market financing announced by energy storage companies increased 151%, with $20.6 billion in 28 deals compared to $8.2 billion in 20 deals in 2021. Six energy storage companies went public in 2022 compared to four in 2021.

LG Energy Solution’s $10.7 billion dollar IPO was a big part of public market financing.

“In addition to record funding activity, energy storage companies and projects were also acquired in record numbers, reflecting maturity in energy storage markets and assets. Energy storage companies with technology advantages and market share are in great demand. Solar plus storage projects are now mainstream and are attracting significant interest from investors.” added Prabhu. “The 30% investment tax credit for standalone storage projects is a game changer going forward and makes project economics really attractive in the U.S.”

A record 28 energy storage companies were acquired in 2022, the most since 2014.

Energy storage project acquisition deals increased by over 20%, with 45 transactions in 2022 compared to 37 in 2021. A record 14.6 GW of energy storage and solar plus storage projects were acquired in 2022, a 400% increase YoY compared to 3 GW in 2021.
