Since April, Affinity Water’s combined arrays at Chertsey and Walton have generated more than 1,095 MWh of electricity – capitalising on the UK’s summer heatwave to produce a daily average of 7,640kWh of electricity throughout June, saving more than £215,000 in energy costs in the process.
The 1,820 solar panels at Affinity’s Chertsey treatment works – which processes 45 million litres of drinking water per day – have produced up to 21% of site energy since energisation and is projected to achieve 12% as an average for the full 12-month period.
