The Councils planning committee is being recommended to approve an application which would see York see its first modern hydro electric power generation on the river Ouse.
The generators would be sited near Naburn Lock.
The proposal comprises two Archimedes screw turbines, a multi-species fish pass, a turbine house building, hydraulic channels, trash screening and access improvements. The scheme is expected to generate a peak power output of less than 500kW and an average annual energy production of 1.2 GWh. The applicant states that this is sufficient to power around 310 homes and provides an effective CO2e saving of around 620 tonnes per year.
The intake would be situated within the island Application Reference Number: 18/02552/FUL Item No: 4b bank just upstream of the weir, with water passing through coarse trash screening before arriving at the sluice gates and turbine house. The screw turbines would discharge into an outfall channel that re-joins the main river just downstream of the weir. A new fish pass will be constructed along the left-hand side of the hydropower scheme.
Naburn Lock is located on the River Ouse in a rural location to the south of Naburn village. The construction of the locks took place in 1757 and 1888 and has created an island upon which is located the workshops, stores and offices associated with the operation and maintenance of the lock. There was formerly a water mill on the island (constructed between 1813 and 1817) which fell out of use around 1955 and was demolished in 1958.
The locks themselves are listed at Grade II (“Old and New Lock”). Directly to the east lies the Naburn Banqueting House, a vacant Grade II listed building, together with the lock keeper’s house. Access to the site is along a single track road from Naburn Lane, which also serves the Naburn Lock caravan park, located to the east.
Naburn Lock is accessible to members of the public and there is a car park and information board at the end of the access road.
The application will be determined on 16th January
