Dong Energy is in talks to sell a £500 million stake in the London Array offshore wind farm to a Canadian pension fund, according to press reports.

The UK’s Sunday Times newspaper reported that the Caisse de Dépôt et placement du Québec pension fund is on the brink of buying half of Dong’s 50 per cent share in the wind farm, which started operating in October 2012.

The potential sale would be the latest offshore wind farm stake to be offloaded by Dong, which has been a key investor in the UK’s offshore wind energy sector.

Dong operates six offshore wind farms in the UK with a combined capacity of around 700 MW, and has a further three offshore wind farms under construction there, including the London Array.

Its partners in the London Array wind farm are Masdar and E.On. The first phase of London Array will generate 630 MW from 175 turbines. The three partners announced in December last year that all the turbines had been installed and the project was on track to be fully commissioned by spring 2013.

If approved, phase two of the project would add a further 140 MW to the scheme.
