Demonstration Projects

*********** CONTEST IS OVER ***********

The University of Maine proposal was rejected for full funding by the DOE in favor of the following three projects. All of the competing projects have been evaluated below and on adjacent pages.


2014-05-07 The DOE Wind Program selected three projects to advance to the second phase of the demonstration, which includes follow-on design, fabrication, and deployment in order to achieve commercial operation by 2017. The following three projects are each eligible for up to $46.7 million in additional funding over four years, subject to congressional appropriations and annual progress reviews. Congress has yet to demonstrate a willingness to support these projects financially, as explained below.

*** Dominion Virginia Power – Virginia Offshore Wind Technology Advancement Project (VOWTAP)
Dominion Virginia Power’s Virginia Offshore Wind Technology Advancement Project Dominion Virginia Power will install two 6-megawatt direct-drive wind turbines 26 miles off the coast of Virginia Beach, Virginia. Dominion’s VOWTAP will help develop methods to install, operate and maintain wind turbines for sites far from shore, such as the Wind Energy Areas established by the Bureau of Ocean Energy Management.

VOWTAP will use a domestically-produced twisted jacket foundation and incorporate hurricane-resilient design features to ensure that offshore wind facilities placed in hurricane-prone waters are reliable, safe and cost-effective.

*** Fishermen’s Energy Atlantic City Windfarm
Fishermen’s Energy Atlantic City WindfarmFishermen’s Energy of New Jersey will install five 5-megawatt direct-drive wind turbines in state waters approximately three miles off the coast of Atlantic City, New Jersey. Fishermen’s Energy Atlantic City Windfarm will demonstrate the use of a twisted jacket foundation that is easier to manufacture and install than traditional foundations, helping drive down the cost of energy produced by the offshore wind system.

Fishermen’s project will act as an at-sea laboratory to further our knowledge about offshore wind, investigate the interactions between turbines, test new control systems, and provide information about potential environmental impacts of offshore wind while reducing the levelized cost of energy from offshore wind.

*** Principle Power WindFloat
Principle Power’s WindFloat Principle Power will install five 6-megawatt direct-drive wind turbines approximately 18 miles off the coast of Coos Bay, Oregon, demonstrating the use of a domestically-developed semi-submersible floating foundation. Principle Power’s WindFloat system will be assembled on shore and towed out to sea, mitigating the need for the costly vessels typically used to assemble and install offshore wind systems at sea.

Principle Power’s WindFloat installations have the potential to harness the more than 60% of U.S. offshore wind resources that are found in deep water.


2014-05-07 UMaine gets federal grant for offshore wind project, but far less than $47 million hoped for [subject to congressional appropriations ]


U.S. Department of Energy (DOE) – EERE Wind
Offshore Wind Advanced Technology Demonstration Projects
“The Wind Program announced funding in 2012 for seven advanced technology demonstration projects, totaling $168 million over six years. These engineering, design, and deployment projects will support innovative offshore installations in state and federal waters, with most targeted to begin commercial operation by 2017.

The program’s seven advanced technology demonstration projects are partnerships with broad consortia that are developing breakthrough offshore wind energy generation projects. The primary goals of these projects are to achieve large cost reductions over existing offshore wind technologies and develop viable and reliable options for the United States. The demonstrations will help address key challenges associated with installing utility-scale offshore wind turbines, connecting offshore turbines to the power grid, and navigating new permitting and approval processes.

Each project has received $4 million to complete the engineering, site evaluation, and planning phase of their project. In 2014, the DOE Wind Program intends to select up to three of these projects to advance the follow-on design, fabrication, and deployment phases to achieve commercial operation by 2017. Each of the three projects will be eligible for up to $47 million over four years, subject to congressional appropriations.

The seven projects selected for the first phase of the demonstration initiative are:

FOUNDATIONS for Wind Turbines

Baryonyx Corporation, based in Austin, Texas, plans to install three 6-megawatt direct-drive wind turbines in state waters near Port Isabel, Texas. The project will demonstrate an advanced jacket foundation design and integrate lessons learned from the oil and gas sector on hurricane-resistant facility design, installation procedures, and personnel safety.
Fishermen’s Atlantic City Windfarm plans to install up to six direct-drive turbines in state waters three miles off the coast of Atlantic City, New Jersey. The project will result in an advanced bottom-mounted foundation design and innovative installation procedures to mitigate potential environmental impacts. The company expects this project to achieve commercial operation by the end of 2014.
Lake Erie Development Corporation, a regional public-private partnership based in Cleveland, Ohio, plans to install nine 3-megawatt direct-drive wind turbines on “ice breaker” monopile foundations designed to reduce ice loading. The project will be installed on Lake Erie, seven miles off the coast of Cleveland.
Dominion Virginia Power of Richmond plans to design, develop, and install two 6-megawatt direct-drive turbines off the coast of Virginia Beach on innovative “twisted jacket” foundations that offer the strength of traditional jacket or space-frame structures but use substantially less steel.”

Floating: Semi-Submersible Platforms

Principal Power of Seattle, Washington plans to install five semi-submersible floating foundations outfitted with 6-megawatt direct-drive offshore wind turbines. The project will be sited in deep water 10 to 15 miles from Coos Bay, Oregon. Principle Power’s semi-submersible foundations will be assembled near the project site in Oregon, helping to reduce installation costs.
The University of Maine plans to install a pilot floating offshore wind farm with two 6-megawatt direct-drive turbines on concrete semi-submersible foundations near Monhegan Island. These concrete foundations could result in improvements in commercial-scale production and provide offshore wind projects with a cost-effective alternative to traditional steel foundations.

Floating: Submersible Spar Buoy Platforms

Statoil North America of Stamford, Connecticut plans to deploy four 3-megawatt wind turbines on floating spar buoy structures in the Gulf of Maine off Boothbay Harbor at a water depth of approximately 460 feet. These spar buoys will be assembled in harbor to reduce installation costs and then towed to the installation site to access the Gulf of Maine’s extensive deep water offshore wind resources.

Principle Power came to Maine from Seattle in 2008 with the hope of testing an innovative floating wind turbine off the coast, in a demonstration project with partners that included the University of Maine. But the company abandoned the plan two years later, citing the state’s parochial politics and what its president says were unreasonable conditions demanded by the university.” …

The University of Maine
2013-07-11 Distorted reasoning, politics will destroy Maine’s chance to lead in offshore wind “For two years I represented a company in Maine that had developed one of the three families of prototypes for floating offshore wind platforms. That company, Seattle-based Principle Power, was the only U.S.-based platform technology represented in the university-led DeepCwind consortium. DeepCwind was charged with developing a deep water test turbine in Maine, but through a series of miscues and bad management the consortium never functioned as a workable group, and the university took over the process completely — with no transparency and little proper accountability. In the end, much delayed, the university launched a one-eighth-scale model wind turbine this spring into a world that had already passed it by.” By Des FitzGerald, Special to the BDN

2010-06-25 UMaine to get $20M for offshore wind – By The Mainebiz News Staff
U.S. Energy Secretary Steven Chu’s visit to the University of Maine earlier this month has led to $20 million in funding for deepwater offshore wind research.
The funding from the Department of Energy will help UMaine develop and test offshore wind technology, and marks the first time the DOE has dedicated specific funding for deepwater offshore wind research, according to a press release from Sen. Susan Collins. Chu visited UMaine’s AEWC Advanced Structures and Composites Center on June 14 at Collins’ request. Last October, UMaine was chosen as one of three universities in the country to receive up to $8 million to fund its offshore wind test center off Monhegan Island, one of three state-selected test sites. UMaine is planning to design and deploy two 10-kilowatt and one 100-kW floating turbine prototypes.
Sen. Collins, a member of the Senate Appropriations Committee, previously secured a total of $25 million for the Maine Offshore Wind Initiative at UMaine, according to the release.
