Perpetuus Tidal Energy Centre Limited is an independent company working with The European Marine Energy Centre in Orkney, together with world leading turbine operators, to deliver tidal stream energy in the next four years.

Perpetuus Energy Limited

A private developer of renewable energy, advanced materials and infrastructure projects. Perpetuus Energy is the majority shareholder of PTEC, which is led by the team:

Rob Stevens: Chairman

Rob is a proven, well respected Chairman with a wealth of experience across the whole maritime sector. He has a passion for the tidal stream energy sector as a potential corner stone of the UK’s excellence in renewable energy.

His particular expertise lies in the Solent region, where, as the author of the 2012 government study ‘Transforming Solent Marine and Maritime supplement’ he understands all the drivers necessary to improve growth in the region and the role of modern composites in marine manufacturing.

He also owns his own small successful consultancy, Stevens Marine Ltd, utilising his experience as CEO of the British Marine and the world-famous London and Southampton Boat Shows.

Rob served in the Royal Navy for more than 30 years, reaching the rank of Rear Admiral and Head of the British Submarine Service. He later became Chief of Staff in Naples, responsible for NATO Maritime Operations in the Mediterranean between 2001 and 2005.

Mark Francis: Project Director

Mark is a co-founder of PTEC. His knowledge of developing and financing growth companies and infrastructure projects, particularly in the cleantech industry, sparked his interest in what became PTEC.

His intellectual and investment stake in the industry has grown with his experience in other advisory, development and finance roles.

Mark’s extensive tidal energy experience now covers technology development, project development and multiple fundraising activities including equity, grants and debt. This expertise is now in much demand across the whole industry.

James Hedges: Head of Finance

James is an Chartered Accountant who has been involved with a wide variety of technology businesses. He was Finance Director of an AIM listed telematics Group for 12 years during which time it grew tenfold and completed five acquisitions.  He has also been a Director of a company developing an underwater autonomous vehicle for the oil and defence markets.

He is an engineering graduate and has over 30 years experience in raising debt and equity finance for both private and public companies.

The Isle of Wight Council

The Isle of Wight Council is a co-founder of PTEC and was instrumental in the early funding and development of the project.


The European Marine Energy Centre (EMEC) in Orkney, Scotland, has recently joined forces with PTEC to focus on site development and optimisation activities. EMEC will contribute its extensive global experience of consenting, grid connection, operations, performance assessment and the introduction of green hydrogen. This work will build upon the activity already completed in achieving site consent.

Established in 2003, EMEC is the first centre of its kind to offer developers of both wave and tidal energy converters the opportunity to test prototype devices in real sea conditions. With two scale test sites and a further thirteen grid-connected test berths, it is home to some of the most innovative marine energy devices currently in development.

EMEC’s holistic knowledge of the renewable industry, developed in Orkney, will be a major boost to the development of tidal energy and local job creation in the Isle of Wight and Solent.

Our Turbine Partners

PTEC is in the process of engaging world leading turbine operators for deployment on site. This includes UK based companies.


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 overview: The TIGER project will demonstrate that tidal stream energy is a maturing industry, capable of achieving an accelerated cost reduction pathway.

The project will build cross-border partnerships to develop new technologies, test and demonstrate up to 8 MW of new tidal capacity at a number of locations around the Channel region, and use the learning from this development to make a stronger, cost-effective case for tidal energy as part of the France/UK energy mix.

The project is the largest ever to be approved not only by the France (Channel) England Programme but by any Interreg programme.
