Sandford Hydro is a small hydroelectric scheme located on the River Thames in Oxfordshire, England. It uses the head of water provided by the weir at Sandford Lock in Sandford-on-Thames, but is actually situated on the opposite bank of the river in Kennington. It can generate 450 kilowatts (600 hp) of electricity with its three archimedes screw turbines. Construction began in 2011, and the plant became operational in 2018.
