THRYBERGH HYDROPOWER - RIVER DON

ERIC WRIGHT SCHEME

The Thrybergh hydropower plant is one of the largest low-head river hydro plants built in Yorkshire.

The £1.2m hydropower scheme will harness the flow of the River Don to power 2 Archimedes screws estimated to produce 1 million kilowatt-hours per annum for the next 75 years, the equivalent of 300 homes.

The scheme also sees the removal of the weirs obstacle to upstream salmon / trout passage, coarse fish and eels providing these species the means to migrate upstream for the first time in centuries.

Circle Control was engaged by Eric Wrights to undertake the LV electrical installation which consisted of Main power cabling, control and instrumentation cabling, containment systems, instrumentation, power distribution and building services.

The scheme was completed on time and to budget.

kirkthorpe weir hydropower - river calder

eric wright Scheme

The Kirkthorpe hydropower scheme is one of the largest low-head river hydro plant ever to be built in Yorkshire.

​The £5.3m hydropower scheme will use the flow of the River Calder to power a single 500kW axial turbine that will generate around 2.3million units of carbon-free electricity per year, equivalent to the consumption of 800 households.

It will run 24/7, 10-11 months of the year, for at least the next 100 years. Salmon, eels and other migratory fish will be able to pass the hydro scheme’s weir safely, protected by the 33-tonne custom-designed inlet screen.


knottingley hydropower - river aire

The Knottingley hydroelectric power plant is one of the largest low-head river hydro plant built in Yorkshire and the largest plant commissioned in England since the start of the century.

The £7.5m hydropower scheme will harness the flow of the River Aire to power a dual Kaplan turbine, half-mile down river from Ferrybridge coal-fired power station. The 500kW scheme will generate renewable electricity for a local flour mill and the local electricity grid 24/7, 11-12 months of the year for the next 100 years.
