March 2019 Area 3: East Huntspill - Mendips. Hinkley Connection Project. We are responsible for providing eabank safe, efficient and reliable energy networks across England and Wales. ortishead We are building a new high-voltage electricity connection between Avonmouth Bridgwater and Seabank near Avonmouth to connect new sources Bristol of power in the area, including Hinkley Point C, EDF Energy’s new Nailsea nuclear power station in Somerset, to UK homes and businesses.
