South West Water has maintained its investment in renewable energy, bringing the total expenditure for K5 to over £4 million. This has included the installation of the company’s largest solar panel array to date at its Exeter headquarters. Along with hydro generation, combined heat and power (CHP) and the wind turbine at Lowermoor Water Treatment Works, South West Water’s 34 solar panel schemes now bring the total capacity for renewable energy generation to over 10MW.
