Deepwater Wind agrees to limit activities to protect Right whales

Effects of Noise on Wildlife, Ocean energy Add comments

Deepwater Wind, which recently won the first-ever competitive lease auction for US offshore wind, has signed an agreement with a consortium of environmental organizations that affirms its intention to minimize potential impacts on critically endangered Right whales. The wind farm’s location, in Rhode Island Sound, is host to foraging Right whales each spring; the agreement delays any pile-driving activity until after May 1, when whales have generally moved north.  In addition, pile driving later in the year will take place only during the day, when any lingering whales can be more easily seen.

The agreement marks an important step forward in marine conservation, with wind energy developers agreeing to key provisions that the Navy and oil and gas exploration companies have resisted: changing their operational schedule to avoid times of particular biological importance in a given area, and agreeing to limit loud noise-making activities to daylight hours.

The current agreement covers pre-construction activities, including pile-driving five foundations, for meteorological towers and perhaps test turbines (the press release does not specify). The Deepwater ONE wind farm will ultimately be home to 150-200 turbines; construction of that phase of the project will create a significant noise footprint, and we will hope that the company agrees to continued protective conditions at that time. A similar agreement by Deepwater for its smaller 5-turbine Block Island Wind Farm does cover the actual construction period; that press release does not mention daylight-only construction, but does delay construction until May. However, a broader agreement between environmental groups and several wind developers does include a provision precluding pile driving at night or in heavy fog; one hopes that this good-faith agreement will indeed be reflected in actual final operational plans.
