Southern Electric Contracting, the subsidiary of Scottish and Southern Energy, has been confirmed as contractor for the 25-year South Coast Streetlighting PFI.
The South Coast Street Lighting PFI is the largest street lighting PFI project in the UK and includes lighting services for Hampshire County Council, Southampton City Council and West Sussex County Council.
SEC will carry out the work through another SSE subsidiary, Tay Valley Lighting.

Colin Hood, chief operating officer of SSE, said: “The PFI approach has proved to be a successful way of replacing older street lighting infrastructure and is delivering better lit streets that helps communities lead safer and more secure lives.”
