June 26, 2019 — Governor Janet Mills has signed legislation directing the Public Utilities Commission to approve the power purchase agreement for the output from New England Maine Aqua Ventus, a pilot offshore wind project. Successful demonstration of the technology has the potential to lead to a 500-megawatt scale project placed in U.S. federal waters.
The project is a 12-megawatt of floating offshore wind pilot developed by Cianbro Corp., the University of Maine and DCNS. Maine Aqua Ventus is supported by nearly $40 million in grants from the U.S. Department of Energy and would be the state’s first offshore wind farm.
This demonstration facility will deploy two 6-megawatt turbines on VolturnUS, a floating concrete semi-submersible hull designed by UMaine south of Monhegan Island, off the coast of Maine. Each floating turbine is held in position in the ocean by three marine mooring lines securely anchored to the seabed, with the electrical generation connected by subsea cable to the Maine power grid on shore.
