February 23, 2021 — New England Aqua Ventus (NEAV), formerly known as Maine Aqua Ventus, will soon begin ramping up efforts to put a single 10-12 megawatt turbine about two miles south of Monhegan Island. The project seeks to lay over 20 miles of cable several feet under the ocean floor from East Boothbay shores to the site.
The floating semisubmersible hull is a University of Maine Advanced Structures and Composites Center design patented as VolturnUS. The UMaine-based researchers and engineers constructed and ran a 1:8, one-to-eight, version of a six megawatt turbine off the coast of Castine.
The project scored $39.9 million in U.S. Department of Energy research and development funds beating out 70 other public and private projects; however, the project cost, about $100 million, and other snags along the way kept the project relatively dormant until Gov. Janet Mills signed a law in November 2019 directing Maine Public Utilities Commission to approve the project’s contract. This paved the way for Aqua Ventus to sign a 20-year power-purchase agreement at above-market rates with Central Maine Power.
When the project rebranded in August 2020 as NEAV, partnering UMaine with Mitsubishi subsidiary Diamond Offshore Wind and German utilities giant RWE Renewables, the two-turbine project morphed into a singular larger one. Since then, NEAV has waited for the COVID-19 pandemic to quiet down before attacking the project in earnest and connecting with the coastal and fishing communities.
