Riverbank Power, a developer of pumped storage hydro and generation assets, announced today that it has closed its merger with Symbiotics Energy Corp., a leading hydro licensor and developer, and completed a concurrent $25 million financing with the Caisse de dépôt et placement du Québec (the “Caisse”). Proceeds from the financing will be primarily used to initiate construction of three run of river projects in the Pacific Northwest which represent a total of 22 MW of new “carbon free” electricity generation. The three projects are expected to be commissioned in 2012.

“The merger with Symbiotics significantly expands and strengthens our team and capabilities in hydro development, construction management and hydro operation,” commented John Douglas, President and CEO of Riverbank. “Our combined development pipeline of 1,100 MW of run of river and over 16,000 MW of pumped storage hydro generation projects in North America will drive our growth.”

“It’s great to be in a position to begin construction of our first three run of river projects. We firmly believe that pumped storage is going to become a big business in North America,” Dr. Vince Lamarra, President and CEO of Symbiotics commented. “Riverbank’s project finance, additional engineering and shared vision on pumped storage were exactly what we needed to grow and capitalize on this emerging opportunity.”

The Caisse financing will allow the merged company to begin construction on the 7.2 MW Dorena Lake (Oregon), 10 MW Applegate (Oregon) and 4.7 MW Clark Canyon (Montana) run of river hydroelectric generation projects.
