The Pershore Weir twin Archimedean screw hydropower scheme, designed and installed by Renewables First, was successfully commissioned on 20th August 2014 by Spaans Babcock. The scheme has since won an Institute of Civil Engineers (ICE) award for innovation.

One of the technical challenges of this project is getting electricity from the turbine house to the point of consumption at Pershore leisure centre on the opposite side of the river some distance away.

Before allowing water to fill the inlet channel, work was undertaken to prevent erosion of its banks over time, as well as encourage plant growth.

Construction works at Pershore Weir have now proceeded to the point where the Archimedean Screw installation can commence.

With work on the turbine house progressing apace, the two Archimedes hydro turbines arrive in tandem at Pershore Weir.

Given that the Archimedean Screws will sit adjacent to the main weir, water from the River Avon will be diverted to and away from the turbines via specially excavated inlet and outlet channels.

Renewables First design a Twin Arcimedean Screw hydro system that will generate 848,000 kWh’s of electricity per year, equivalent to powering 200 UK homes and annually offsetting 3,601 tonnes CO2.

Renewables First are commissioned to provide a turnkey package to specify and design the Twin Archimedean Screw hydroelectric system, secure the appropriate consents and project manage the construction, installation and commissioning of the hydro system.
