Proje ct Context and Background – Vineyard Wind Lease area OCS-A 0501 – ~261 square miles – Northern tip of Lease Area is ~35 miles offshore from Cape Cod, and ~14 miles south of Martha’s Vineyard and Nantucket – Study and analysis began as soon as lease acquired in 2015 – Building on earlier consultations by project and Vineyard Power – Offshore geological surveys in 2016 and 2017 Additional surveys planned for spring and summer 2018 March 2018 5

Scour Protection Scour – Stone placed around foundation – Sized between 4-12 inches – 3-6 feet high Scour protection radius 22-26m (72-85ft) – Protects the foundation from the removal of sediments near the base. – Dimensions – 138ft - 170ft diameter March 2018 11

Proposed Offshore Cable Corridors – 2 possible corridors: Western & Eastern (only 1 will be used) – Multiple options through Muskeget Channel – August/September 2017 surveys, more in 2018 – Routing – Considerations include water depth, bathymetry, SSU areas, etc. – Federal and state waters (Land Under the Ocean) – Avoidance of mapped eelgrass habitat and core habitat for whales – Minimization of impacts to hard/complex bottom areas – Installation via jet-plow, plow, or mechanical trenching – Target burial depth = 5 to 8 feet (1.5 to 2.5 m) – 6-foot-wide swath affected by trenching – Where sand waves are present, dredging will be used to achieve target burial depth – Extensive outreach with local and regional fishermen and their representatives March 2018 12
