Description

In terms of electricity supply, Alderney in the Channel Islands, relies solely on imported diesel fuel from the UK to run the islands seven diesel generators. With increasing demand for electricity, the increasing cost of hydrocarbon derived power and increased risk in terms of security of supply, coupled with increasing need to tackle climate change, there is an increased need for Alderney to find alternative, clean sources of electricity. In combination with the FAB Link Interconnector development of the tidal resource will enable Alderney to become a net exporter of clean, renewable energy, significantly reducing their dependency of imported fossil fuels.

To this end, OpenHydro has formed a partnership with Alderney Renewable Energy, who own the rights to develop the tidal energy in 50% of the territorial waters of the Channel Island of Alderney. Currently, the Race Tidal project, initially earmarked to be 300MW, is under development with installation planned from 2025.

Xodus was commissioned to prepare a scoping report for a 300 MW tidal energy project off the north east coast of the island. The scoping built on previous EIA and consenting work, including seabed and marine wildlife surveys, that had been undertaken for previous potential tidal projects around the island.

Alderney is not a member of the European Union, and as such is not subject the requirements of the European EIA Directive. However, in line with their commitment to apply best practice to the regulation of marine renewable energy projects, under Schedule 1 of the Renewable Energy (Alderney) Ordinance 2008 (as amended) ACRE (Alderney Commission for Renewable Energy) require that a Licence application is supported by an Environmental Statement (ES). This is in line with the UK framework for EIA which has developed in line with the UK’s consenting regime for marine renewable projects. In line within this framework, the scope of the EIA proposed was proportionate to the size and location of the proposed development. 

Scope
  • Site visit and initial consultation meetings
  • Development of a stakeholder engagement strategy, taking into account previous consultation activities and lessons learnt
  • Production of a scoping report requesting an EIA Scoping Opinion from ACRE in consultation with the relevant statutory consultees
  • 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
Value Added
  • Implementation of key lessons learnt from previous tidal array EIAs in Scotland and Northern Ireland, including Open Hydro technology
  • Development of an appropriate and proportionate EIA scope, building on the previously completed scoping report and focusing on the issues of greatest concern
