Project: TIGER (Tidal Stream Industry Energiser)

Timescale: 2019 – 2023 (47 months)

Funder: Interreg France (Channel) England Programme

Funding: ERDF funding € 29 million / total project budget € 45.4 million

Project website: www.InterregTiger.com


Project overview

The tidal energy capacity in the Channel region is predicted to be nearly 4 GW – enough to power up to four million homes.

The TIGER project, launched in 2019 to drive tidal energy growth in the UK and France, has demonstrated the significant value tidal stream energy can bring to the future energy mix, economies and supply chains in both the UK and France.

TIGER is the largest project funded by the Interreg France (Channel) England Programme, with €48.4 million invested to drive collaboration and cost reduction through tidal turbine installations in the UK and France.

The project, led by the Offshore Renewable Energy (ORE) Catapult, enabled installation of four new tidal stream energy devices at test sites in and around the Channel region, with a further 16 in development. This created a total of 3.6 MW new tidal capacity, with a further 57.4 MW in the pipeline. The project positively contributed to three TIGER developers successfully accessing £20 million per annum of tidal stream energy generation subsidy awards, through the UK Government’s Contracts for Difference (CfD) scheme and new discussions have opened on French tidal stream Feed-in-Tariffs.

Instrumental to the success of the project was collaboration between the 18 TIGER partners across the UK and France, spanning turbine developers, ocean energy demonstration sites, research organisations, and local and regional authorities, each supporting the tidal industry as it moves towards commercialisation.


EMEC role

EMEC supports communications and stakeholder engagement, as well as site development, resource assessments and performance assessment of technologies.


Tidal resource modelling and ADCP campaigns

EMEC ran ADCP campaigns at Yarmouth in the Isle of Wight and Raz Blanchard in France, as well as tidal resource modelling of the channel region and providing technical support for the TIGER partners.


Test procedures

EMEC developed four test procedure reports for the tidal sector:


PTEC site consenting

EMEC led on the reconsenting works at the Perpetuus Tidal Energy Centre (PTEC) in the Isle of Wight. We supported an updated Section 36 consent application, full planning application, Environmental Impact Assessment and SSEN grid application; these efforts were rewarded in December 2021 as the site was granted planning permission making it eligible to bid into the government’s Contracts for Difference scheme.

EMEC also contributed to a research paper: Impacts of tidal stream power on energy system security: An Isle of Wight case study.


Supply chain and investor engagement

EMEC has support the growth of the tidal energy supply chain, coordinating a series of supply chain webinars, meet the buyer events, and working with the investment community to reduce risk and increase confidence in the sector.

Supply chain webinars:

  • Subsea cables and connectors
  • Tidal energy opportunities for steel manufacturing and supply chain learning
  • Growing the supply chain for cost effective reliable composite blades, tooling and sensor design for tidal turbines
  • Anti-fouling and anti-corrosion requirements of tidal turbines
  • Reliability & condition monitoring of tidal turbines
  • Onshore and offshore mobilisation and logistics

Meet the buyer webinars:

  • French supply chain
  • UK supply chain


TIGER case studies

EMEC has produced a series of ten case studies to highlight each stage of the tidal turbine deployment ‘life-cycle’ to collectively illustrate examples of cost reduction technology, successful deployment of offshore renewable energy in the Channel-Manche region, based on the work of the TIGER project.

Reports and publications

The project included real world demonstrations, published scientific research industry reports, specifically:

These reports demonstrate the cost reduction trajectory that can be achieved, as well as how the UK and France can generate over 80% of materials from the local supply chain, create up to 45 jobs per MW deployed – exceeding the wind and solar industries, and contribute up to £17 billion to the UK economy by 2050.
