In its first foray in the US energy market, Sydney-headquartered growth investor Wollemi Capital and Retail Employees Superannation Trust (Rest) fund have acquired a majority stake in US-headquartered owner and operator of distributed solar assets Redball Energy.
Washington-based Redball owns and operates approximately 4,500 rooftop solar systems on homes and businesses in the Mid-Atlantic and New England regions, which include Maine, New Hampshire and New York.
It does not sell or install panels directly to homeowners but provides project financing, streamlined payments and asset owership.
The investment supports Redball’s next phase of growth to expand its installer partner network, continue its selective expansion in its current markets and broaden its offering to include battery storage.
Wollemi Capital US Co-Head Natalie Volpe said Wollemi Capital US Co-Head Natalie Volpe said Redball was a natural fit with Wollemi’s strategic focus on backing real asset portfolios that are proven, distributed and scalable.
“The Redball team has built an impressive business through a disciplined, partnership-led approach, and the opportunity for distributed energy in the US is significant as electricity demand rises,” Volpe said.
“We’re excited to partner with Redball and bring our experience backing distributed solar and storage platforms to the US market.”
Redball Co-Founder John Marciano said the company seeks overlooked opportunities in the energy transition and back the teams bringing clean energy projects to market at scale.
“In Wollemi [we’ve] found a partner who shares that vision and will help take Redball to the next level, as America’s need for affordable energy and resilient, distributed infrastructure continues to grow.”
On 2 November 2026, Rest announced it had expanded its total commitment to $250 million (USD 170 million) for Wollemi Energy Group-owned Sydney-based energy and battery storage platform MPower.
It follows a $220 million commitment to Wollemi in 2025. At that time Rest Private Markets General Manager Marina Pasika said the commitment to Wollemi, and MPower, would generate long-term returns for members given Wollemi’s approach to advancing decarbonisation.
“Many of our members have decades until retirement, including around one million under 30, so we look for investment opportunities that can support members throughout their lives, while benefitting from the major economic and societal shifts expected to shape the future,” Pasika said.
