Scotrenewables Tidal Power Ltd
Founded in 2002, Scotrenewables Tidal Power Ltd is a renewable energy research and development business based in the Orkney Islands.
The Scotrenewables tidal turbine is a unique floating tidal technology designed to minimise installation and operational costs. The device hosts two propellers which fold up while being towed. The system has been extensively trialled through scale model testing and a 250kW prototype, the SR250, successfully connected to the national grid at the Fall of Warness tidal test site at the end of March 2011 and is currently in a two-year test programme.
Initial tests involve short-term deployments of the device on its moorings followed by disconnection and towing back to harbour for inspection. The testing programme is being undertaken in incremental stages, culminating in a three-month period of continuous grid-connected operation at EMEC’s tidal test site at the end of 2012.
The device, measuring 33m long, was constructed at Harland & Wolff in Belfast in 2010 and weighs 100 tonnes. When it is not deployed onsite, the device is based at Hatston Pier in Kirkwall.
Building on the success of SR250 testing to date, Scotrenewables Tidal Power are in the process of developing the SR2000: a larger 2MW ‘commercial scale’ turbine more suited for tidal array deployment. This is due to be tested at EMEC prior to commercial deployment in the Lashy Sound between the islands of Eday and Sanday. This project will be developed in two phases with an initial 10MW array planned to be installed by 2017.
