Maine PUC declines to OK Statoil offshore wind term sheet

Today the Maine Public Utilities Commission declined to approve a term sheet offered by Statoil North America, Inc. for a long-term power purchase agreement from its proposed Hywind Maine floating offshore wind project.

Sutton Island, Maine, about 80 miles downeast of the proposed Hywind Maine project.

In 2010, Maine enacted a law designed to support the development of offshore wind and other marine renewable energy projects.  Among other features, that law required the state Public Utilities Commission to conduct a competitive solicitation for proposals for deep-water offshore wind energy pilot projects, meaning grid-tied floating wind projects at least 10 nautical miles offshore.  The statute gave the commission authority to direct mainland utilities to enter into power purchase agreements with one or more responding developers if certain minimum criteria were met.  This authority was discretionary, meaning the commission could choose not to order the utilities to sign a deal even if it met those criteria.

In September 2010, the commission issued its request for proposals under the program. Over the ensuing years, Statoil emerged as the apparent leading respondent, proposing the "Hywind Maine" project, a four-turbine, twelve megawatt project south of Boothbay Harbor.  Commission staff and Statoil negotiated the terms of a proposed power purchase agreement, which became public this summer.  Among those terms was a proposed energy price of between $290 and $320 per megawatt-hour, escalating annually, for the first 41 gigawatt-hours of energy produced each year.

That term sheet was the subject of deliberations by the Maine commission this morning.  After two hours of discussion, two of the three commissioners had stated that they would vote against approving the term sheet.  They expressed concerns about the cost of the contract, as well as uncertainty over the deal's benefit to Maine and Maine ratepayers.

The Maine commission's action bears some resemblance to that of the Rhode Island Public Utilities Commission in 2010 when it rejected a proposed contract between utility National Grid and offshore wind developer Deepwater Wind on the grounds that $244 per megawatt-hour was not a "commercially reasonable" price.  The Rhode Island commission ultimately approved a renegotiated deal with Deepwater Wind at a comparable price.  Similarly, the Maine commission invited Statoil to revise its proposal to offer more benefits to Maine, and to present a renegotiated deal for further deliberation.  Will Statoil be able to sweeten its offer and convince the commission that its contract is a good deal for Maine?

Floating offshore wind in US waters?

US coastal waters may soon see the development of floating offshore wind electric generating projects. Being able to install offshore wind turbines on floating platforms, as opposed to towers fixed to the seabed, may enable projects to tap into the vast deepwater ocean energy resource. This would represent a major step in history and technology, and could provide real data on the actual feasibility and costs of offshore wind in the United States.

2012 may bring the deployment of North America's first floating offshore wind project. The DeepCWind Consortium and the University of Maine plan to test a floating wind turbine several miles off the Maine island of Monhegan next summer. The Monhegan project is designed as a pilot project, not a commercial effort. Nevertheless, the lessons learned off Monhegan could be used to shape a larger commercial project in 2013.

Historically, this project could be the first operating US offshore wind development. As 2011 closes, US waters still host neither operating commercial offshore wind projects, nor installed pilot projects of significant size. This is not for lack of interest. Universities and businesses are investing in offshore wind research and development, while developers eagerly pursue commercial projects in nearly all US jurisdictions. Commercial proposals range from projects fully permitted projects but unbuilt, to concepts still in the formation phase.

Technologically, a floating offshore wind project would demonstrate potential solutions to the engineering challenges posed by deep water sites. At least two floating turbines have recently been deployed around the world. The first, Statoil’s 2.3 megawatt Hywind unit, was installed off Norway in 2010. In November 2011, Portuguese utility Energias de Portugal (EDP) teamed up with Principle Power, Inc. to deploy a 2 megawatt turbine on a WindFloat platform off Portugal. The semisubmersible WindFloat design allows the unit to be towed in a horizontal position to the site, then erected without the use of a lift vessel. These test projects demonstrate some of the technologies required for deepwater offshore wind projects. A US project would represent a similar demonstration of new technology.

Floating offshore wind projects appear to have some momentum in Europe, and are poised to make a splash in US waters in the next year. Whether these efforts take hold depends on broader questions of economics and policy as much as on technology. What will 2012 bring?

Maine ocean energy advances

Maine's offshore wind industry may be moving forward, as the federal agency responsible for offshore wind site leasing is now considering a request by Norwegian energy company Statoil to lease a site for a Maine deepwater floating wind project.

The Maine site for which Statoil has applied lies over 12 miles offshore, south of Boothbay Harbor.  It lies in United States waters south of Damariscove Island.  This places the site near the pre-selected Damariscove Island wind site in Maine state-jurisdictional waters.  Statoil's proposed site is also southwest of the Monhegan offshore wind site.

Statoil's request to the federal Bureau of Ocean Energy Management was submitted on an unsolicited basis.  No BOEM Call for Information and Nominations (the agency's primary competitive solicitation tool) was in effect for these waters.  Under current regulations, unsolicited leases face a slightly different process for review, including a determination of whether there is any competitive interest in the site.

Statoil is a large and diverse energy company headquartered in Stavanger, Norway, and owned primarily by the government of Norway.  Statoil's portfolio includes petroleum, gas, pipeline, and electric utility businesses.  Statoil is now exploring ocean energy opportunities, and developed the world's first full-scale floating wind turbine, the 2.3 megawatt Hywind unit.  Statoil has applied for a site lease off Maine, which could be its first US offshore wind site.

BOEM has deemed Statoil NA's lease application to be complete, and the applicant to be legally qualified.  Now BOEM is engaged in a review of Statoil's technical and financial qualifications.

Tomorrow morning, a joint state-federal task force will meet to review Statoil's request.  The Maine Task Force of the Bureau of Ocean Energy Management consists of a broad array of agency representatives.  Tomorrow's meeting will feature presentations by representatives from the governor's energy office, Maine Public Utilities Commission, United States Coast Guard, Department of Defense, NOAA, as well as BOEM and the Department of Interior itself.  This meeting will be held on December 8 at the Marriot Hotel in South Portland, Maine, at 9:30 a.m.

Separately, Statoil is negotiating with staff from the Maine Public Utilities Commission for a long-term contract to sell the project's output to utilities.  Statoil responded to the Maine commission's 2010 request for proposals for pilot floating offshore wind projects.  This offshore wind long-term contracting program was established by a Maine law designed to facilitate the development of a deep-water offshore wind energy pilot project.

If the Commission approves a long-term contract for the project's output, it could give the wind farm sufficient revenue certainty.  At the same time, the Commission is required to weigh the costs and benefits of any such contract, and must find that ordering a utility to buy the energy, capacity and renewable energy credits at the price and other terms proposed would not have an unreasonable impact on the utility's rate.
