A mammoth floating solar farm is being built in London.
Developers Ennoviga Solar and Lightsource Renewable Energy are working with Thames Water to create the 23,000-panel scheme on Queen Elizabeth II reservoir.
The utility firm aims to self-generate a third of its energy by 2020.
The floating solar farm will have a peak capacity of 6.3MW and is expected to generate 5.8M kW hours in its first year.
Lightsource will oversee the deployment of more than 61,000 floats and 177 anchors to provide the platform for the solar array.
Thames Water energy manager Angus Berry said: “Becoming a more sustainable business is integral to our long-term strategy and this innovative project brings us one step closer to achieving our goal – this is the right thing for our customers, the right thing for our stakeholders and most importantly the right thing for the environment.”
