UK engineers building Europe's largest floating solar farm

Currently being installed on Thames Water’s Queen Elizabeth II reservoir near Walton-On-Thames the project is the result of a collaboration between Thames Water, and specialist solar developers Ennoviga Solar and Lightsource Renewable Energy, which is funding the initiative.

The array is made up 23,000 photovoltaic panels which are being mounted on a pontoon consisting of 61,000 floats and 177 anchors. The 57,500 square metre structure will cover around a tenth of the surface of the reservoir (an area equivalent to 8 football pitches).

According to Thames Water, when up and running the facility will have a total installed peak capacity of 6.3 megawatts and is expected to generate 5.8 million kilowatt hours in its first year. This electricity will be used to help power the nearby water treatment works.

The project is part of a wider effort by the utility firm to reduce its reliance on the grid. Last year, it generated 12.5 per cent of its electricity requirements from renewables.
