Our History
Rooted in America. Powering its future.
Geronimo Power was built on a simple but powerful idea: America’s energy future starts at home. Farmer-friendly and community-focused, our roots in rural America shape how we do business —grounded in hard work, trust and respect for the land. These values continue to guide us as we build resilient, American-made energy infrastructure that powers local prosperity and strengthens our nation’s backbone. Two decades later, we’ve grown from a three-person start-up to a national leader in the power industry.
As we look ahead at the growing demand for power and digital infrastructure, Geronimo Power is ready. We are advancing innovation in solar, wind, storage, and data center colocation, while staying true to our roots.
Our vision is clear: farmer-friendly, community-focused and leading America into a reliable energy future.
Founding Story
Farmer Friendly
Our story began with Noel Rahn, a southwest Minnesota farmer turned successful investor. Despite his career achievements, Noel’s heart never left the farm. His family worked the land for generations—his father farmed until age 99 and his brother still does today.
Noel built his career in finance, managing investments and starting businesses. Noel especially loved investing in land. When asked why, Noel replied simply, “Because they’re not making it anymore.”
Community Focused
Along the way, he became a mentor to many, including Blake Nixon, a friend of his daughter who asked him for an internship during his sophomore year of college. Noel agreed, and Blake ended up completing two internships at his investment firm, The Rahn Group, before joining him full-time. There, Blake managed venture capital and private equity investments.
When a wind developer approached Noel in 2003 about leasing his farmland, he was intrigued and listened closely. Worried that the deal didn’t feel fair to farmers and threatened to pit neighbors against one another, he ultimately declined the offer. Then, he turned to Blake and said, “Let’s do it ourselves.”
From that moment, the idea of building a wind energy company was born. Neither Noel nor Blake knew much about the power industry. Blake jokes that, in those early days, they didn’t even know the difference between a telephone line and a power line. But Noel’s determination was unwavering. Together, they spent afternoons walking the land, studying the wires overhead and imagining what might be possible.
Fearless Leadership
In 2004, their vision came to life with the Odin Wind Farm on Noel’s land. Originally just a side venture within The Rahn Group, Blake proposed establishing it as a separate legal entity. That meant it needed a name, and Noel, without hesitation, chose Geronimo.
To Blake, the choice seemed sudden. To Noel, it was anything but. A voracious reader and lover of history, Noel had long been captivated by Native American culture and the injustices they endured. Among the figures who fascinated him most was Geronimo, admired for his fierce, unyielding spirit. In Geronimo, Noel saw a kindred soul—someone who revered the land, refused to conform and stood firm for what he believed in.
The name carried exactly the kind of courage, respect and boldness Noel wanted for the company.
That decision marked the official birth of what is now Geronimo Power.
