DPME & DBE Joint Venture
West Islay Tidal
Energy Site
Currently holding two Crown
Estate Agreement for Lease
(AfL)
• Islay 30MW,
• Fair Head 100MW
Fair Head Tidal
Energy Site
West Islay Tidal
• Consent submission
(site & western cable)
Q2 2013
• Technology Neutral but
designed around MCT
SeaGen S/Alstom TGL
• Build schedule 2015 –
2016
• 6MW with EU FP7
Fair Head Tidal
• 100MW AfL Fair Head
Granted Oct 12
• Technology Neutral
Approach
• Scoping – Q2 2013
• Application – “Q3 2014”
(Subject to....)
• Installation – Grid
dependent
Three Phases to Consent Application
• Scoping Report
• Survey scope and
methodology
• Baseline Surveys
• Existing Data
• Site Survey
• Environmental Impact
Assessment
• Site/device specific
• Habitats Regulations Appraisal
• Cumulative Impact Assessment

PROJECT
DESCRIPTION
•
•
•
Design Envelope “Rochdale Envelope”
•
•
•
•
•
R. v Rochdale MBC ex parte Milne (No. 2) [2000]
Endorsed by Scottish Government
Define a “worst case” approach to assessing impacts
Consolidation in Industry ...BUT....
Recognition that detailed definition is not possible due
to:
–
–
–
–
Unknown seabed geology
Insufficient operational experience of devices
Insufficient detailed knowledge of resource
Lack of security from supply chain
Project Design Envelope - What do we know?
•
•
•
•
•
•
•
•
•
30MW
TEC will be HATT
Between 1 & 2MW per Unit
Between 15 & 30 TEC`s
6MW planned SeaGenS (FP7)
Revised AfL Area (TBC)
Inter-array Cabling
Preferred Export Cable Route
Islay Landfall(s)
Project Design Envelope – WHERE/WHAT?
MCT SeaGen S Mark 2 (2MW) – 15 TEC
•
•
•
•
•
TGL (1MW) + 3 MCT – 27 TEC
3 to 15 MCT SeaGen S Mark 2 TEC`s (2MW)
Up to 24 TGL TEC`s (1MW)
Flying leads from each TGL TEC
SeaGen TEC for marshalling & export connection
Export voltage probably 33kV
Project Design Envelope Goals
• Compromise between FLEXIBILITY & DEFINITION
• Focus on TEC, the rest is methodology
• Need to ensure that issues with “less likely”
scenarios don’t impact on “most likely”
BUT
• Critical we have enough flexibility for viability
Achieving the goals - Assessors
Achieving the goals – Regulators
• Regular Meetings and updates SNH & MS
– Project Design Envelope
– Cumulative Impacts
– HRA
• Balance open dialogue with regulators with
FOI requests
Achieving the goals – Consultation
Challenges
•
•
•
•
•
Technology
Installation Costs
O&M Costs
Grid Availability
Consenting
– Offshore Works
– Onshore Infrastructure (Substation/line)
Key Areas for Focus
•
•
•
•
Fishing and other Commercial Interests
Recreational Users and any knock on effect Locally
Potential Visibility on and offshore
Local Benefit
– Consenting: surveys, vessels, assessors
– Installation: Onshore construction
– O&M: If site maintenance strategy RIB/Workboat access
• Safety - Navigation
• Cumulative Impact Effects
