Building the first phase of a floating wind-power project off Maine’s coast would create as many as 341 jobs and trigger at least $120 million in investment, with half of it going to Maine-based companies, according to a draft power-purchase contract to be filed Wednesday with the state.

The investment would add a small charge for 20 years to Central Maine Power Co. bills. An average home customer would pay an additional 73 cents a month at the start, $8.70 in the first year.
Advocates hope the pilot project will set the stage for a deep-water wind power industry in Maine that could create thousands of jobs and billions of dollars in spending over time.
“It’s really an overall investment in the future,” said Jake Ward, vice president for innovation and economic development at the University of Maine, which is a partner in the Maine Aqua Ventus project.
The state Public Utilities Commission will have to decide whether the project is a good deal, during deliberations expected next month. A period for written public comment will be set before then.
Next spring, the federal Department of Energy will decide whether the technology behind Maine Aqua Ventus is innovative enough to receive a $46 million grant aimed at creating large wind farms, far out at sea, that can produce power at competitive rates.
At first glance, the project apparently would have a similar impact on ratepayers as the now-defunct project proposed by the Norwegian energy company Statoil, while offering more economic benefits.
TEST MODEL WORKING AS EXPECTED
Maine Aqua Ventus is being proposed by Maine Prime Technologies, a for-profit spinoff that represents the university and two general partners, Maine-based Cianbro Corp. and Emera Inc. of Nova Scotia.
In May, the partners launched a one-eighth-scale model of a floating turbine off Castine. The unit is made of advanced composite materials designed to fight corrosion and reduce weight. Its hull is made of concrete, which can be produced in Maine and has a longer life span in the ocean than steel.
The prototype is now generating a small amount of power and collecting information. It already has endured extreme sea and wind conditions and is performing as expected, Ward said.
The partnership plans to develop a full-scale pilot wind farm off Monhegan Island by 2016. It would consist of two turbines, each with a capacity of six megawatts. Based on the availability of wind, the project is expected to generate 43,000 megawatt-hours a year, enough to power 6,000 average homes.
Beyond an investment of $120 million to $166 million, the full-scale project would have other benefits, according to the draft term sheet to be presented to the PUC:
• Half of the money would be spent with companies and workers in Maine. At least $7 million would be spent on services provided by UMaine.
• A science, math and technology curriculum linked to the project would be provided to Maine high schools, as well as collaboration with public colleges for training and education programs.
• Monhegan Island, which has some of the country’s highest electricity rates, would get some free power from the project. The island also would be connected to the mainland with fiber-optic cable, to boost Internet access speed.
COMPARISON TO PREVIOUS PROPOSAL
The partners say the cost-saving technologies of Maine Aqua Ventus put the project in a good position to win the critical federal funding for a giant, floating wind farm off the coast of Maine that could generate 100 to 500 megawatts. And the expertise developed by the venture could form a research and development cluster that helps build and supply a global, emerging energy sector.
