Client: Pelamis Wave Power Limited

Aegir Wave Power Limited, a joint venture company comprising Edinburgh based technology developer Pelamis Wave Power and Swedish utility Vattenfall, was proposing to develop a commercial wave farm off the southwest of Shetland. The wave energy project had an estimated initial capacity of 10-20 MW and would include up to 25 Pelamis wave energy convertors, an export cable, cable landfall and onshore substation.

The objective of the scoping process and report was to:
• Engage and inform stakeholders and provide open channels for communications in order to encapsulate risks and concerns whilst enhancing benefits
• Establish an understanding of existing environmental baseline data sets pertinent to the project as well as clarity on data gaps
• Review environmental risks associated with potential impact scenarios to enable effective management of risks through ongoing EIA and project design work

The draft scoping report went through a consultation process before finalisation in an attempt to enhance its value and ensure it contained adequate information to allow delivery of a suitably informed Scoping Opinion by the regulators, their advisors and wider stakeholders.


  • Site visit and consultation meetings
  • Development of a stakeholder engagement strategy
  • Production of a scoping report requesting an EIA Scoping Opinion from Marine Scotland
  • Baseline data review (including previous surveys) and recommendations for future surveys and data to support EIA
  • Detailed scopes for impact assessment studies
  • Proposed ES content
  • Organisation and facilitation of a public consultation event in Shetland, including poster and leaflet preparation
  • Consultation on the draft scoping report
  • Completion of navigational Preliminary Hazard Analysis (PHA) as part of scoping

Value Added

  • Comprehensive consultation exercise to capture risks and enhance benefits early in the project
  • Development of an appropriate and proportionate EIA scope
  • Implementation of key lessons learnt from previous marine energy array EIAs in Scotland and elsewhere
  • Early commissioning of PHA allowed for scoping of all aspects of the EIA and associated Navigational Risk Assessment (NRA)
