- Apollo boosts commercial solar investment with $400M joint venture in Illinois.
- Summit Ridge’s 2GW pipeline expands U.S. energy independence and grid resilience.
- Partnership builds on Apollo’s $58B commitment to energy transition investments.
Apollo Funds have committed up to $400 million to a new joint venture with Summit Ridge Energy, aimed at owning and operating commercial solar assets across Illinois—marking a major expansion of their existing relationship.
This move builds on Apollo’s $175 million strategic investment in Summit Ridge in 2022 and signals growing momentum behind energy transition assets. Summit Ridge Energy, already one of the largest U.S. owner-operators of commercial solar, manages over 2GW of projects in development or operation across seven states, powering more than 40,000 homes and businesses.
“We are pleased to expand our relationship with Summit Ridge Energy and enter this new partnership,” said Corinne Still, Partner at Apollo. “This represents a compelling opportunity to invest in solar projects poised to contribute domestic power generation capacity to meet growing electricity demands.”

Apollo’s broader strategy reflects a deepening push into climate and infrastructure. Over the past five years, Apollo-managed funds and affiliates have committed or arranged approximately $58 billion in climate and energy transition-related investments.

“As we expand our footprint of solar assets, Summit Ridge Energy is advancing a more reliable and locally driven energy system,” said Adam Kuehne, CIO of Summit Ridge. “We’re proud to partner with the Apollo team as we continue driving the nation toward greater energy independence.”

The partnership aligns with Apollo’s broader goal of fueling what it calls a “new industrial renaissance,” supporting U.S.-based clean energy development and job creation.
