Thames Water sets sights on solar power

4 August 2011

Thames Water has signed a deal to install photovoltaic systems large enough to cover 15 football pitches at three London sites.

The contract is being carried out in partnership with Ennoviga Solar, a photovoltaic developer.

Under the £7m, 25-year deal, Ennoviga Solar has created an investment company that will own and maintain the solar arrays.

The investment company will repay all the financing by selling the clean electricity produced to the water company at a market-competitive price, according to a statement by Thames Water.

The solar arrays are being fitted in otherwise unusable places at three operational sites in the capital.

One is on the roof of the Beckton desalination plant in Newham. Another is on the top of large storm tanks built in the 1800s at Crossness sewage works in Bexley. The third is on redundant sand filters at Walton water treatment works in Sunbury.

When fully complete, the three sites will provide annually more than 4,500 MWh of electricity, enough to run around 970 average-size homes, according to the statement. 

The scheme will shave £100,000 a year off Thames Water's electricity bill, providing 0.5 per cent of its 1,180 GWh.

After installation is complete at the three sites, Thames Water said it plans to fit more photovoltaic systems at up to 100 of its smaller locations.

Thames Water recently set a voluntary target of reducing its greenhouse emissions by 20 per cent on 1990 levels by 2015.
