Thornton Bank

C-power is a special purpose company created by several Belgian and European renewable energy utilities and publicly owned organizations. In 2003, the company was awarded the concession to build the 325 megawatt Thornton Bank Wind Farm - the first offshore wind farm in the Belgian North Sea and one of the largest in Europe.

Thornton Bank is located 30 kilometers off the Belgian coast. When full production capacity is achieved in 2013, the site will generate around 1,000 gigawatt-hours of clean electricity annually - enough to meet the needs of 600,000 people and avoid some 450,000 tons of carbon dioxide emissions a year. This will make Thornton Bank a major contributor to Belgium's 2020 renewable energy targets. The project comprises three phases:

  • Phase 1: 6 x 5 MW turbines and the first of two 150 kV submarine cables (completed in 2009)   

  • Phase 2: 30 x 6,15 MW turbines, offshore substation and the second 150 kV submarine cable (completed in 2012) 

  •  Phase 3: 18 x 6,15 MW turbines (to be completed in 2013)
