Community Energy England Award for Saddleworth Hydro
Saddleworth Community Hydro wins the Community Energy Collaboration Award, recognising the ground-breaking association between a community group and United Utilities.
Institute of Civil Engineers Award for Pershore Weir hydro scheme
Renewables First picks up two prestigious West Midlands Institute of Civil Engineers (ICE) awards in recognition of its recently completed hydro scheme at Pershore Weir.
Institute of Civil Engineers Award 2015 for Saddleworth Hydro
David Balmforth, President of ICE, awards Renewables First the North West Civil Engineering Community Project Award 2015, for their work on the Saddleworth Community Hydro scheme.
Hydro scheme commissioned at Pershore Weir
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.
Pershore Leisure Centre Hydro Powered
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.
Hydro inlet channel incorporates special erosion control measures
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.
Archimedes screw installation due at Pershore Weir
Construction works at Pershore Weir have now proceeded to the point where the Archimedean Screw installation can commence.
Archimedes hydro turbines arrive at Pershore Weir
With work on the turbine house progressing apace, the two Archimedes hydro turbines arrive in tandem at Pershore Weir.
Commissioning Saddleworth hydro scheme
Renewables First commission England’s first community owned, high head micro hydro scheme.

Cross flow turbine delivered to Dovestone Reservoir
The turbine and generator was delivered to site pre-assembled in order to reduce on-site installation time.
Saddleworth Hydro penstock connection
The penstock is being connected to the existing pipe work within the valve house and will divert water (flow) towards the turbine house. The configuration of the pipework enables the asset owner to isolate the flow from the penstock at any time, thus maintaining the physical separation of the reservoir asset from the Dovestone hydro scheme.
Turbine house emerges out of the ground at Dovestone Reservoir
With the subterranean levels completed, construction of the turbine house super-structure is now underway. This is designed to blend-in with existing reservoir architecture, thus reducing its visual impact.
Constructing the underground hydro turbine house
Designed by Renewables First, the turbine house will be a triple-layer construction, with a loading bay and hoist beam above ground, with the turbine chamber and sump below.
The “breakthrough”: linking the Crossflow turbine to the watercourse
One of the key design requirements of the Saddleworth Hydro scheme is to ensure that the compensation flow used to drive the Crossflow turbine is returned to the natural watercourse.
Pershore Weir hydro scheme commences
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.
Screw turbines for Pershore hydro scheme
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.
Archimedes Screws for Pershore Weir hydro scheme
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.
Saddleworth Community Hydro scheme works begin
With Planning Permission and all other Consents granted for the Saddleworth Community Hydro project, excavation work was able to commence for the turbine house chamber, sump and culvert.
Renewables First design Saddleworth Community Hydro project
Renewables First design expertise integrates a 55 kW Crossflow into the existing dam infrastructure at Dovestone Reservoir. The key design principles of the project are to maintain the compensation flow to the Chew Brook, generate electricity from the flow released and allow for reservoir draw-down during emergency procedures.
