There is currently a boon of offshore wind energy in the development along the east coast. New York state has the largest ambitious plan to develop manufacturing, deepen their ports, build out their electric grid, and erect wind farms offshore. When Maine’s technology goes through its final stages of approval becoming viable, the state’s floating wind turbine platform technology is projected to attract states and nations where deep water turbines aren’t currently feasible. This is because the University of Maine’s patented VolturnUS floating platform wind farm technology can be located offshore in deep water. In addition they can generate more electricity as the winds in deep water are greater. The technology also has interchangeable components that can insure easier maintenance on location.
On January 25, 2021,Maine Governor Janet Mills proposed a series of actions to advance the nation’s first floating offshore wind research array in federal waters and to protect more heavily fished state waters.
In a letter to Maine’s licensed commercial fishermen, Gov. Mills announced that she will propose for the Legislature’s approval a 10-year moratorium on new offshore wind projects in waters managed by the state and that she has directed the Governor’s Energy Office to review offshore wind regulations and again opened channels and opportunities for meaningful input from fishermen and marine industries siting the proposed research array.
“Offshore wind is a significant clean energy and economic opportunity for Maine, which we will pursue responsibly, transparently and in consultation with our fishing and maritime industries,” said Gov. Mills. “By focusing on floating offshore technology deep in the Gulf of Maine where the wind is strongest, we will protect Maine’s maritime heritage and coastal economy while being out front in this new competitive industry.”
These actions seek to protect fishing and recreational opportunities within the three miles of coastal waters managed by the state, which are more heavily fished than federal waters. The actions also allow for additional substantive input from the fishing industry as the Maine continues to pursue the nation’s first floating offshore wind research array in the Gulf of Maine and its associated economic and energy benefits.
“This moratorium is an important step that will allow us to continue to alleviate concerns expressed by fishermen and will give us an opportunity to have a more focused conversation around the proposed research array,” said Maine Department of Marine Resources Commissioner Patrick Keliher. “We will continue to work to see that all stakeholders are afforded the opportunity to have a voice in the decision-making process. Maine fishermen are vital to our state’s economy and heritage and I applaud Governor Mills’ decision to support their opportunity for input into the shared use of our state’s valuable marine resources.”
“With some of the most ambitious renewable energy goals in the country and over a decade of experience in offshore wind, Maine can embrace the potential of offshore wind to provide clean energy for our state,” said Dan Burgess, Director of the Governor’s Energy Office. “The research array puts Maine in the driver’s seat to ensure offshore wind benefits the state and minimizes harm, which is why focusing on research is best for the state to both address the growing threat of climate change and to maximize its economic benefits.”
The research array is proposed for an area 20-40 miles in the Gulf of Maine in a proximate location that would allow the array to connect to the energy grid in southern Maine. The most likely locations for that connection have been determined to be either Wyman Station in Yarmouth or Maine Yankee in Wiscasset.
Starting in late December, the Governor’s Energy Office and Department of Marine Resources initiated discussions with Maine’s fishing industry and other stakeholders to determine a site for the research array in the broad area of the Gulf of Maine that meets basic siting criteria. In addition to the mainland grid connection, the site for the array would also require suitable water depths and bottom topography to support the experimental floating offshore wind turbines.
No decision has yet been made on a site, which as a research array, is only expected to cover some 16 square miles of ocean or fewer and contain no more than a dozen turbines. This limited scope is approximately one-tenth the size of comparable commercial-scale offshore wind farms elsewhere in New England and was purposefully done by Governor Mills as a reasonable and measured step forward to pursuing this new technology.
As the first floating offshore wind research array in the U.S., the array would study how the new technology interacts with the marine environment, the fishing industry, and performs both generating energy and sending it to the mainland grid. Permitting and construction of the floating array is expected to take up to five years, in advance of a research period of roughly 20 years. After this period, the array would be decommissioned.
As envisioned, the research array would use floating offshore wind technology pioneered over the past decade by the University of Maine’s Advanced Structures and Composites Center. Last summer, the University announced a new $100 million partnership with two global leaders in offshore wind energy, Diamond and RWE Renewables, to develop the UMaine patented technology through a new company called New England Aqua Ventus.
Separately from the research array, New England Aqua Ventus is permitted to establish a single-turbine demonstration site for its technology in state-managed waters near Monhegan. As a permitted project, this site would not be subject to the proposed 10-year moratorium. There are no current applications for offshore wind projects in state-managed waters, where a majority of Maine’s commercial fishing occurs.
Estimated to drive some $70 billion investment over the next decade alone, offshore wind has become a priority by many states on the eastern seaboard to meet growing demands for clean, renewable energy to combat climate change and the severe economic disruption caused by the COVID-19 pandemic. There are more than 25,000 megawatts of offshore wind energy in the development pipeline along the east coast.
With some of the highest sustained offshore wind speeds in the world, the federally managed waters of the Gulf of Maine are a likely destination for commercial-scale wind projects to meet growing energy demands. Proposing a research array is a prudent, proactive step for Maine to ensure Maine’s interests and values remain foremost in any offshore wind development.
Mainealso remains a participant in the Gulf of Maine Task Force, a regional planning effort with Massachusetts and New Hampshire through the federal Bureau of Ocean Energy Management, to evaluate commercial-scale offshore wind projects in the Gulf.
A study of port opportunities in Searsport, as a potential central hub for the offshore wind industry, which would include the transportation, assembly and possibly fabrication of floating turbines, is also underway through the Maine Department of Transportation.
