Hydro Green Energy, LLC (HGE) is a privately-held renewable energy development company with proprietary hydropower technology. The company holds U.S. Patents 6,955,049 and 7,837,411, five foreign patents and has dozens of pending U.S. and foreign patents. Hydro Green Energy focuses on developing new hydropower generation at existing non-powered dams.
Due to Hydro Green Energy’s ability to license and manufacture in parallel, projects could be brought on-line in approximately 18 months. And, while not needed to ensure profitability, its low-impact hydropower projects are eligible for a variety of state and federal renewable energy incentives, increasing their attractiveness.
Hydro Green Energy is presently developing 28 hydropower projects in 14 states. The company’s project pipeline will result in the development of nearly 300 MW of clean, renewable energy. To better understand hydropower in the context of the nation’s energy portfolio, below you will find a comparison of power technologies that are utilized in the United States today.
