The Rochdale bus and Metrolink interchange, being built in England, will be a European first, being powered by hydropower generation.
The £11.5 million interchange, is next to the River Roch, and when it opens next year it will be the first building of its kind in Europe to have integrated hydropower generation, using the river to generate its electricity.
A hydroelectric turbine has been installed which converts energy from the river as it flows rapidly through a weir. The weight of the water turns the screw-shaped turbine, generating electricity. The turbine produces up to 86,000kWh of electricity every year, which will help to reduce the interchange’s carbon footprint by over a quarter.
The turbine is driven by an ‘Archimedean screw’, which was supplied by Spaans Babcock, a specialist contractor with a local base in Heywood.
It has been funded by Transport for Greater Manchester, the European Union’s INTERREG IVB Ticket to Kyoto project, the Northwest Development Agency, Rochdale Borough Council and the Environment Agency.
