Cape Wind

Project Overview

The Bureau received a request from Cape Wind Associates, LLC (CWA) for a lease, easement or right-of-way to construct and operate an offshore wind facility located in Federal waters 4.7 miles offshore Cape Cod, Massachusetts, on Horseshoe Shoal in Nantucket Sound. Landfall for the transmission cable would be in Yarmouth.Photo of a wind farm offshore Sweden.

The project consists of 130, 3.6 megawatt wind turbine generators covering approximately 25 square miles in federal waters offshore Massachusetts with the maximum capacity to produce about 468 megawatts. The average expected production from the wind facility could provide about 75 percent of the electricity demand for Cape Cod and the Islands of Martha’s Vineyard and Nantucket. At average expected production, Cape Wind could produce enough energy to power more than 200,000 homes in Massachusetts.

Construction and Operations Plan

The Construction and Operations Plan (COP) was submitted by CWA in October 2010 (and updated in February 2011 and April 2011). The COP is available for download below:

To determine whether a supplemental environmental impact statement (EIS) was necessary before the Bureau came to a decision on CWA’s COP, the Bureau prepared an environmental assessment (EA). On February 22, 2011, public input was requested to inform the decisionmaking process by suggesting new issues or contributing information with regard to potential environmental effects. The comment period closed on March 9, 2011. Further details are available in this
Notice of Preparation of an Environmental Assessment Approximately 160 comments were received and are available here.

On April 18, 2011, BOEMRE issued an Environmental Assessment and a Finding of No New Significant Impact, and a Record of Decision containing additional terms and conditions of the approval to be incorporated into the COP.

Background

The Cape Wind Energy Project was proposed by Cape Wind in November 2001. Prior to the Bureau’s involvement, the United States Army Corps of Engineers (Army Corps) assumed the lead federal regulatory role under the River and Harbors Act, and issued a draft Environmental Impact Statement (EIS) in November 2004. Following the Energy Policy Act of 2005, the Bureau assumed lead federal responsibility and initiated its own independent environmental review pursuant to the National Environmental Policy Act (NEPA).

The Bureau published the Cape Wind draft EIS in January 2008 and the final EIS on January 2009. On April 28, 2010, Department of Interior Secretary Salazar announced the availability of the Record of Decision (ROD) for the Cape Wind Project. The ROD documented the bureau’s decision to select the Preferred Alternative at Horseshoe Shoal in Nantucket Sound described in the final EIS.

Record of Decision (20 MB PDF)

Secretary of the Interior Ken Salazar and Cape Wind Associates President Jim Gordon signed the nation’s first lease for commercial wind energy development on the Outer Continental Shelf (OCS) on October 6, 2010. The project area offered in the lease is comprised of approximately 46 square miles on the OCS in Nantucket Sound offshore Massachusetts. The 33-year lease for the area off the coast of Cape Cod, Mass. will cost the company $88,278 in annual rent prior to production, and a 2 to 7 percent operating fee during production. The fee is based on an estimate of what the project’s output would sell for in regional markets.

 Green Bullet  Public Archaeology Laboratory, Inc. ("PAL") conducted an assessment of the visual effects to nearby historic properties from the proposed Cape Wind Energy project at Horseshoe Shoals. The "Visual Impacts Assessment" or "VIA" identified a number of historic properties on Cape Cod, Nantucket and Martha's Vineyard that fall within the area of potential effect for visual effects and assesses the effect on these historic properties. The VIA is referenced in the Revised Findings of Adverse Effect document. The two reports can be found here:
