Washington, D.C. – December 22,2025 – National Trust Energy Capital, a subsidiary of the National Trust Community Investment Corporation (NTCIC), announces that Karin Berry, Managing Director, will retire at the end of the year. Paul Holshouser, currently Director of Solar Transactions, will step into the leadership role starting on January 1st, continuing National Trust Energy Capital’s mission to deliver impactful renewable energy investments.
In 2024 alone, the U.S. added more than 30 gigawatts of solar capacity, according to the Solar Energy Industries Association (SEIA). That’s enough to power over 5 million homes—and the momentum isn’t slowing down
Karin Berry has been a major player in the renewable energy space for over 30 years, with experience spanning international energy policy, government service, and private sector investment. Before joining National Trust Energy Capital, Karin advanced clean energy initiatives in the public sector, including her work at the U.S. Trade Representative’s office, where she focused on international energy policy and government service. She later held leadership roles at PNC Energy Capital and Guggenheim Capital Markets, helping drive the adoption of renewable technologies and innovative investment strategies across diverse markets.
During her tenure as the inaugural Managing Director of National Trust Energy Capital, Karin Berry led origination, structuring, and closing of renewable energy tax credit investments, building deep relationships with investors and developers nationwide. Her leadership helped expand National Trust Energy Capital’s reach and reputation, and she leaves a legacy of integrity, innovation, and community impact. Since joining National Trust Energy Capital in 2015, she has overseen solar tax credit investments and managed a rapidly growing portfolio of renewable projects, responsible for over $1 billion in tax credit investments.
I will miss the NTCIC team and our all-in commitment to delivering community benefit. Of course, I’ll still be doing what I can to support this community in my retired life!
