ScotRenewables SR2000 at EMEC

Project Site Annex IV

Title: ScotRenewables SR2000 at EMEC
Start Date:
October 01, 2016
Country:
Technology Type:
Info Updated:
April 18, 2017
Project Status: 
Device in operation
Technology: 
Floating Tidal Turbine SR2000
Project Scale: 
Single device
Installed Capacity: 
2 MW
Description: 

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.

Location: 

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.

Process Status: 

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.

Licensing Information: 

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.

Key Environmental Issues: 

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.

Baseline Assessment: ScotRenewables SR2000 at EMEC

General Description:

A review of the EMEC Fall of Warness Test Site Environmental Appraisal identified a number of potential residual impacts that are considered relevant to the SR2000 deployment.

ReceptorStudy Description Design and Methods Results Status
  • Physical Environment

Potential for changes to hydrodynamics and physical processes

Desk based study

No important impacts of relevance to hydrodynamics or physical processes are expected from developments at Fall of Warness.

Completed
  • Benthos

Introduction of marine non-native species (via vessels, devices or other equipment)

Desk based study

Local vessels will be used therefore there is no potential for introduction of NNS via vessels.  The SR2000 device was towed from Northern Ireland to Orkney.  The risk of introduction of MNNS is considered to be very low and no significant impacts are expected as a result of the proposals.

Completed
  • Fish and Fisheries

Introduction of marine non-native species (via vessels, devices or other equipment)

 

Benthic fish and shellfish

Desk based study

Local vessels will be used therefore there is no potential for introduction of NNS via vessels.  The SR2000 device was towed from Northern Ireland to Orkney.  The risk of introduction of MNNS is considered to be very low and no significant impacts are expected as a result of the proposals.

Completed
  • Fish

Electromagnetic field (EMF) effects on diadromous fish, gadoids, and elasmobranchs

Desk based study

No significant effects

Completed
  • Large Vertebrates

Potential impacts on marine mammals and basking as a result of support vessel activity, e.g. noise and physical presence

Desk based study

Installation of the SR2000 will be completed using a standard multi-cat work vessel assisted by a RIB.  Installation activities will be completed in a relatively short timescale.

No significant effects on any sensitive species are expected from this low level of vessel activity.
