About Us
Who we are
Argyle Energy was founded in 2022 with a vision to drive the transition to renewable energy by developing high-impact projects across the Midwest and Northwest. Our focus is on the Dakotas, Nebraska, and Wyoming, regions rich in renewable energy potential, where we are committed to creating sustainable energy solutions that will power communities for generations to come.
With more than 40 years of collective experience in land development, renewable energy, project finance, design, construction, and operations, our co-founders bring a wealth of knowledge and a deep commitment to the projects we undertake. We understand that building a sustainable energy future requires more than just technical expertise—it requires collaboration, trust, and careful attention to the needs of both the environment and the communities we serve.
At Argyle, we recognize that successful renewable energy projects rely on more than just efficient energy production. They require strong community partnerships, environmental responsibility, and strategic site selection. We work closely with landowners, community leaders, and stakeholders to ensure our projects are aligned with local values while also forming key partnerships with leading manufacturers, engineers, suppliers, and construction firms to bring these projects to life.
From initial planning through to project completion and eventual decommissioning, our team is focused on delivering sustainable energy solutions that benefit the environment, local economies, and the communities in which we operate. Together, we are committed to creating a cleaner, more resilient energy future.
