ScotRenewables Tidal Power Limited (SRTP) first installed their full-scale prototype floating tidal energy technology (SR2000) onto its moorings at EMEC’s Fall of Warness tidal test site in October 2016. The device provided first power to the grid in November 2016. The SR2000 is the most powerful tidal turbine in the world. It has been designed to minimise the whole lifecycle cost of electricity production from tidal energy. The flexible mooring system means the device can be installed in any water depths of 25, + due to the flexible mooring system.
The device was installed at the European Marine Energy Centre (EMEC) tidal device test area in Fall of Warness, Orkney, UK. Water Depth: 33m. Tidal range: 3m. Tidal speeds up to 3.7 m/s.
The SR2000 was first deployed at the site and produced power to the grid in October 2016, however it was subsequently removed in the same month to avoid winter storms. In March 2017 the SR2000 was successfully redeployed and was operating at full power.
In July 2016 ScotRenewables were granted a marine license to permit the deployment of the SR2000 at the Fall of Warness site. The marine license can be accessed from here.
The sites seabed ranges from eroding sub-littoral sandbanks in the east to smooth scoured bedrock ridges and platforms with occasional boulders towards the center of the site. Fall of Warness is not a protected area; however, there are protected sites in close proximity. These include:
- Faray and Holm of Faray SAC – protected for its grey seal populations.
- Sanday SAC – Protected for its harbor seal populations, intertidal mudflats and sandflats, inshore sublittoal rock and subtidal sandbanks.
- Muckle and Little Green Holm SSSI – Nationally important grey seal breeding colony (Around 3% of the national breeding population).
EMEC has produced a specific Environmental Appraisal (EA) for the Fall of Warness site.
