Kielder Water is also the site of England's largest hydro electric plant. In December 2005, RWE Npower Renewables bought the rights to operate the plant and sell the electricity generated by it, with a contract lasting until 2025. Following the takeover, the turbines were refurbished in 2005–2006, which increased the efficiency of the electricity generation. Controls were also updated, meaning that the plant can be operated from Dolgarrog in Wales. The plant generates electricity using dual turbines which produce 6 megawatts (MW) of electricity. It also uses a 5.5 MW Kaplan turbine, which generates electricity when water release takes place. A 500 kilowatt (kW) Francis turbine also generates constantly from the compensation flow of water from the reservoir into the North Tyne. This gives the reservoir a total generating capacity of 12 MW, and an average production of 20,000 MWh of electricity per year, a saving of 8,600 tonnes of carbon dioxide per year compared to fossil fuel based methods of generation.
