Massachusetts Wind Energy Area• Largest Wind Energy Area on East Coast

~743,000 acres (3,000 square kilometers)

Water depths range from 35 – 65 meters

Average wind speeds 9.2 – 9.4 m/s

• NREL projects 5 GW of generating capacity potential

• To be separated into four lease areas

• BOEM auction expected November/December 2014

Rhode Island /Massachusetts WEA

• BOEM held the first U.S. auction for offshore wind lease on July 31, 2013 for the RI/MA Wind Energy Area

• Deepwater Wind won the 164,750-acre lease area RI/MA for $3.8 million

• Development potential of 1.2 GW

Offshore Wind Research

• Methods– Aerial Surveys – Underwater Passive Acoustic Data

• MassCEC & BOEM– NE Aquarium– College of Staten Island– UMass Dartmouth SMAST

• Survey Periods– Year 1 -- 10/11 - 10/12– Year 2 -- 12/12 - 12/13– Year 3 -- 3/14 - 3/15

• Results– Year 1 reports: Dec. 2013– Year 2 reports coming

• Benthic Surveys (2012, 2013)

Contractor – Global Wind Network (GLWN)

Offshore Wind Transmission Project

Purpose:• Identify and characterize interconnection points

• Describe transmission infrastructure components and system requirements for WEA development scenarios

• Identify routes that minimize transmission cable distance with least environmental impact and fewest conflicts (through EEA update of MA Ocean Management Plan)

• Support coordinated state permitting for the transmission routes in state waters

• Support coordinated access and permitting process for areas in federal waters
