Our Capabilities


Putting our energy and expertise to work

Our leadership team is comprised of experts in all aspects of the hydropower industry, including manufacturing, financing, power purchase agreements, energy technology, markets, operations and regulations. We have extensive experience working with regulatory agencies and have established close relationships in many sectors of the energy industry. Together we focus on improving hydropower efficiency and adding capacity for existing hydropower dams, and building hydroelectric capabilities to non-powered dams.

Our History

Cube Hydro was formed in 2014 when Enduring Hydro entered into a partnership with I Squared Capital Infrastructure Fund to pursue the development and acquisition of hydroelectric power plants in North America.  Enduring Hydro was originally founded in 2011 by Dr. Kristina M. Johnson, former Under Secretary of Energy for the U.S. Department of Energy.  During her tenure at DOE, Dr. Johnson identified the underappreciated potential of hydropower and left DOE to start Enduring Hydro.  In 2012 and 2013, the Enduring Hydro team successfully completed the permitting and construction of the 6 MW Mahoning Creek hydroelectric plant on an existing U.S. Army Corps dam located in Kittanning, PA.  This was the first hydroelectric power plant built in Pennsylvania in over 25 years.  Since its inception in 2014, when Cube Hydro acquired a 49% ownership interest in Mahoning Creek, a new build, the Company has grown rapidly.

In September 2017, Dr. Johnson left Cube Hydro to become the Chancellor of The State University of New York State.  John Collins was subsequently appointed Chief Executive Officer.  On October 8, 2019, Ontario Power Generation (OPG) announced the finalization of the acquisition of Cube Hydro Partners and Helix Partners (collectively, Cube Hydro) from I Squared Capital.  Cube Hydro and Eagle Creek Renewable Energy are being combined to form OPG’s U.S. hydro platform, operating together under the name Eagle Creek.

Cube Hydro and its OPG Eagle Creek US affiliates own and operate a total of 85 hydroelectric plants in the United States, representing 619 megawatts of capacity.  In addition, the companies own minority interests equivalent to approximately 10 megawatts in thirteen other hydroelectric plants and two solar facilities in New England.
