PTEC partners with world-leading and state-of-the-art tidal turbine manufacturers

Perpetuus Tidal Energy Centre (PTEC) today announced its major partnerships with global tidal turbine manufacturers, SCHOTTEL HYDRO GmbH and TOCARDO Tidal Turbines. The transformational tidal energy generation project, having achieved all key project consents earlier this year and with a signed grid connection offer, is now a step further towards delivery with full operations to commence from 2020.

The 30MW project, to be created off the Isle of Wight, will allow long-term operation of SCHOTTEL HYDRO and TOCARDO turbine arrays, simultaneously optimising their performance and delivering reliable electricity to the grid. PTEC is also expected to create and safeguard hundreds of jobs and attract significant investment into the local economy, building on the success of the existing British marine and offshore wind sectors.

Project Director, Mark Francis said: “We are very pleased to announce that TOCARDO and SCHOTTEL HYDRO are partnering with us to deliver 30MW of predictable electricity generated from the tidal currents to the south of the Isle of Wight. This is a major milestone for the project, which is of strategic importance to the UK’s tidal industry and will accelerate the growth of the sector as well as enable a continued cost reduction path for future tidal stream projects. Working with world leading and state-of-the-art turbine manufacturers under our unique project structure will be the key to our success.

We are currently working with SCHOTTEL HYDRO and TOCARDO to identify the optimal site layout and designs, taking into consideration the outputs of our Environmental Impact Assessment and consented envelope. These decisions will be finalised in due course, with onshore construction scheduled to begin next year.”

Niels A. Lange, MD from SCHOTTEL HYDRO said: “It is a privilege to be part of the largest consented tidal stream energy project in England and Wales. We are excited to join such a ground-breaking development and world-class team and look forward to seeing PTEC drive the development of tidal power both in the Solent area and, indeed, worldwide.

We will be spearheading this development through our UK subsidiary TidalStream Ltd., which has been active in this industry for over five years. One of the benefits of our TRITON platform technology is the maximising of local manufactured content. For our demonstrator in the Bay of Fundy, Nova Scotia – due to be installed next year – the local content will be in the order of 75%, bringing manufacturing jobs and benefits to the local community. We are constantly seeking ways to advance our technology and ensure it is fully commercialised for worldwide production. PTEC is the perfect opportunity for us to achieve this.”

Hans van Breugel, CEO of TOCARDO said: “Engaging with PTEC is a significant step in the commercialisation process of TOCARDO’s standard offshore tidal solution, the UFS. After having deployed our turbines at various sites in the Netherlands and operating these projects successfully, we feel confident to jointly realise this world leading multi-MW tidal energy farm at the Isle of Wight. PTEC follow a thorough step-by-step process towards successful project deployment, just like TOCARDO does in product development, and we are proud to have been selected.”


World Leading UK Tidal Power Project Gains Approval

A state-of-the-art tidal energy generation project to be constructed off the Isle of Wight has today been given approval. The Marine Management Organisation has given the go-ahead to the offshore elements of the Perpetuus Tidal Energy Centre (PTEC). With the onshore part given local planning consent in September 2015, the project at 30MW is now the largest consented tidal stream energy project in England and Wales. It has also secured its future connection to the UK’s electricity grid.

PTEC is now set to become a world leader in large-scale tidal power production, using the motion of the changing tides to generate clean and reliable electricity for the UK.

PTEC will commercially operate a range of different world-leading turbine technologies in a five square kilometre area off St Catherine’s Point, the southernmost tip of the Isle of Wight. The project will bring international companies to the UK and accelerate the country’s adoption and understanding of tidal energy.

A number of tidal turbine manufacturers have already expressed interest in partnering with PTEC to install their turbines. Once operational, PTEC will generate sufficient clean electricity to power more than 15,000 homes.

Evidence from other tidal energy projects suggests that PTEC could also create or safeguard hundreds of jobs and attract significant investment into the local economy. Opportunities for businesses on the Isle of Wight and around the Solent area will be generated both in the construction and operational stages of the project.

Project Director Mark Francis said:

“We are delighted with the decision. PTEC will be pivotal to the future growth and success of the UK’s tidal energy industry.

“We started work on the PTEC project back in 2010 and secured the seabed Agreement for Lease in November 2012. Following a rigorous development and consenting phase, we have created a project that will deliver reliable power to the UK’s grid and has attracted world leading turbine manufacturers to partner with us in its implementation.

“We now look forward to working with the MMO, local planning authority and all relevant stakeholders in completing the final development phase before we begin construction.”

PTEC is operated as a joint venture between private company, Perpetuus Energy Ltd, and the Isle of Wight Council. It is hoped that the construction of the project will start in 2017, with potential to be generating electricity from late 2018.

TIDAL energy onshore plans for a Ventnor site have been given planning permission by the Isle of Wight Council

Statement from Mark Francis, Project Manager:

We are delighted with the decision last night (8th September 2015) to grant planning permission for the onshore elements of the project. PTEC has gone to great lengths to ensure the substation has a minimal visual impact on the surrounding area, which is why it has been designed with a living roof and will be built from local natural stone and wood.

Our application for the offshore elements of the project is still being considered by the Marine Management Organisation (MMO), however, we have recently proposed to significantly reduce the maximum allowable height of the tidal devices from 18 metres above water to 9 metres. These changes have been accepted by the MMO and we expect the MMO to make an announcement on the consent determination later this year.

Perpetuus Tidal Energy Centre moves a step closer to becoming a world leading multi technology tidal array demonstration facility

The Local Planning Authority has today given the green light for outline planning for the onshore elements of the Perpetuus Tidal Energy Centre (PTEC).

A planning application was submitted to the Isle of Wight Council in November last year for a substation and associated infrastructure in Ventnor. The planning committee has today, 9th June 2015, passed outline plans for it to be built on existing development land close to Flowers Brook.

This is the first phase of the project; an application for the offshore elements is being considered by the Marine Management Organisation (MMO), and PTEC will now work to achieve full planning from the Local Planning Authority

Project Manager Mark Francis said, “We are delighted with today’s decision. We are really excited by this project and the potential it has to benefit not just the Island and its residents, but the UK more widely. We are working closely with the Marine Management Organisation and we expect a decision later this year. We hope to have the site operational by 2018.”

The total electrical output from the site is expected to be around 65,000 MWh per year which will provide enough clean electricity to power the equivalent of over a quarter of Isle of Wight homes. PTEC will also be investing in grid upgrades for the Island, which will help enable the development of other renewable energy projects on the Isle of Wight.

David Cameron confirms support for Perpetuus Tidal Energy Centre (PTEC)

In Prime Minister’s Questions today Mr Andrew Turner, MP for the Isle of Wight, asked if David Cameron would join him in supporting the Perpetuus Tidal Energy Centre,  a public / private partnership. Mr Turner explained the centre, based on the Isle of Wight, will provide the world’s leading grid connected tidal array test facility, placing the UK at the forefront of tidal energy technology, protecting existing jobs and creating several hundred new ones.

The Prime Minister confirmed the UK is now the most attractive market in the world for investment in offshore wind and in marine renewables. He stated, “We want to maintain that world leading position. We want to harness the economic benefits and the environmental benefits that brings and we want to see local centres of expertise and from what I can see the Perpetuus Tidal Energy Centre sounds like exactly the sort of exciting initiative that we should be supporting.”


Perpetuus Tidal Energy Centre (PTEC) has submitted a consent application for a tidal farm to the south of the Isle of Wight

PTEC has applied to the Marine Management Organisation (MMO) and Isle of Wight Council (as Local Planning Authority) for permission to construct and operate a tidal energy demonstration site off St Catherine’s Point to the south of the Isle of Wight. If consent is granted, PTEC will be the first of its kind in the world.

The electricity will be generated from tidal currents in the sea south of the Isle of Wight, supplying the Island with clean, renewable energy.

Mark Francis, Project Manager for PTEC said, “We are really excited by this project and the potential it has to benefit not just the Island and its residents, but the UK more widely.

“It will be the first of its kind anywhere in the world, reinforcing the UK’s reputation as world-leaders in the wave and tidal industry.

“We have already undertaken a comprehensive programme of engagement with regulators, the local community and other stakeholders, and will continue to work closely with them as the project progresses. We look forward to working with the MMO and Local Planning Authority during the consent determination process, which is due to end in 2015.”

The total electrical output from the site is expected to be over 50,000 MWh per year.

PTEC’s consenting works, including the environmental impact assessment (EIA), were led by Royal HaskoningDHV, an engineering consultancy firm, due to its track-record of successful EIAs, and its reputation for consent delivery for projects in the marine environment. Royal HaskoningDHV also managed the Front End Engineering Design (FEED) for PTEC’s offshore and onshore works.

If the submission for consent is successful, then construction could start in late 2016, creating hundreds of jobs.

PTEC BBC South Today Coverage

BBC South Today covered a story on the Perpetuus Tidal Energy Centre (PTEC) and the proposed plans to bring a tidal farm to the Isle of Wight.

The coverage provides an insight into the research required for bringing commercial devices to our shores, the environmental surveys that are essential as part of the pre-planning application process, and the significant positive economic impact that would result if PTEC gets the go-ahead.  If plans are approved it will help to maintain the UK’s leading position in this hi-tec industry.

The Consents and Planning Process

In order to license the PTEC development, applications must be submitted to the Marine Management Organisation (MMO) for:

  • Permission to generate and supply electricity under Section 36 (S36) of the Electricity Act 1989
  • Permission to place devices and cables on the seabed (a Marine Licence) under the Marine and Coastal Access Act (2009)
  • Permission to construct infrastructure onshore, either under S36 deemed planning or under the Town and Country Planning Act 1990

The Marine Policy Statement (MPS) provides a framework for marine licencing contributing to the achievement of sustainable development in the United Kingdom marine area.

The development also requires an Environmental Impact Assessment (EIA) under the Environmental Impact Assessment Directive (85/336/EC). The purpose of an EIA is to ensure that any project with the potential to have significant environmental effects, due to its nature, size or location, is subjected to an effective assessment to inform the application for planning permission. The output of an EIA is an Environmental Statement.
All Environmental Statements are publically accessible once they have been submitted to the appropriate authority for consideration. Representations from the public, as well as local authorities and nature conservation bodies are invited at this time as part of the consultation process. The appropriate authority will take into consideration all responses and representations while considering a project application. Once a consent decision is made it will be announced publically.

Applications for consent for the PTEC project were submitted at the end of November 2014.

If consent is granted, then construction will take place between 2016 and 2018. Once construction is completed, the facility will be commissioned and operational during 2017-2018.

The differences between the existing tidal device test centre at EMEC (Orkney) and the proposed PTEC tidal array demonstration facility (Isle of Wight).

The proposed Perpetuus Tidal Energy Centre (PTEC) would be the world’s leading multi-technology tidal array demonstration facility, providing the next step in the commercialisation of tidal energy and moving on from the developments made at the European Marine Energy Centre (EMEC) testing facility which provides developers of both wave and tidal energy converters with purpose-built, accredited open-sea testing facilities.

The fundamental difference between EMEC and PTEC is that EMEC tests and develops conceptual technologies, while PTEC moves these developed prototypes towards commercialisation. The purpose of EMEC is to test and develop conceptual designs that have only previously trialled in test benches, tow tanks or via computer models, whereas PTEC would enable in situ long-term demonstration of pre-commercial devices and arrays of devices. The devices at EMEC are in test phases meaning they are frequently out of action, often for long periods of time in bad weather, and require a high level of servicing, alterations and both repairs at sea and on land. The purpose of PTEC would be to demonstrate the long term running, management and monitoring of arrays of proven devices (tested at EMEC or equivalent sites). Maintenance work for these prototypes is expected to be less than for EMEC and is more likely to focus on the management and monitoring aspects of arrays prior to them being deployed on larger scales elsewhere.

Rationale for Site Selection

The Crown Estate owns the majority of the seabed and seashore around the UK. The Crown Estate agrees leases for marine developments, dredging and aggregate extraction on a commercial basis. As part of this process, the Crown Estate has agreed leases for a number of areas of seabed for wave and tidal projects over the last few years.

An agreement for lease for the PTEC site was awarded by the Crown Estate in November 2012, along with two other tidal sites in Orkney (Scotrenewables) and Strangford Lough (Minesto). Agreement for lease is the first stage in securing the right to construct and operate a tidal energy development from the Crown Estate but is subject to receiving further consents from the relevant authorities. Tidal sites identified from 2013 onwards were selected via the independent ‘UK Wave and Tidal Key Resource Areas Project’ that was undertaken on behalf of The Crown Estate in 2012. Information on tidal resources was provided by the Energy Technologies Institute who model tidal energy resources across the UK continental shelf. Unlike wave resources, tidal resources only occur at discrete locations.

PTEC has an Agreement for Lease with The Crown Estate for a specific area of seabed of approximately 5km2. The PTEC site is unique and was selected by the PTEC project team on the basis of the following combined parameters:

  • Tidal current velocities
    • PTEC reviewed tidal velocities over a 40km2 area before selecting the optimum site. The selected site has relatively low turbulence, especially in comparison to nearer shore areas. The channel the site overlays has prime ‘directionality’ meaning that the ebb and flood flow directions are very close to 180 degrees phase difference; this is a key consideration for tidal turbines to reduce/prevent yaw. 
  • Bathymetry and site depth
    • The site provides optimum variation in depth, which is required for the site to be suitable for deployment of a number of different devices.
    • The bathymetry in the area is well suited to deployment of floating, moored and seabed mounted devices.
  • Environmental and physical constraints
    • The offshore development site is outside all ecological and geological designations; although the export cables will cross part of the Special Area of Conservation (SAC). This crossing is being discussed with Natural England.
    • The site avoids hard constraints such as the disused munitions dump and shipping lanes.
    • The location minimises disruption to the Round the Island Race route.
    • The onshore site has been selected to sit outside the Area of Outstanding Natural Beauty (AONB) and the Site of Special Scientific Interest (SSSI).
  • Accessibility
    • Proximity to shore allows safe and efficient access for installation and operation & maintenance (O&M) vessels.

Environmental Impact Assessment

EIA LogoAn Environmental Impact Assessment (EIA) of the project has been completed, which was led by Royal HaskoningDHV. This formed part of the consent application which PTEC Ltd submitted in the fourth quarter of 2014.

Engineering and Design

A Front End Engineering Design (FEED) study was also completed for PTEC Ltd, by renewable energy specialists IT Power. The FEED study helped PTEC Ltd to decide on a number of design and technology details which was assessed during the EIA process.


Marine mammal and seabird surveys were undertaken from August 2013 to July 2014 using the Mabel Alice survey vessel.  Analysis of this data and the impact assessment work is now underway.


Marine geophysical surveys and seabed (“benthic”) ecology surveys were completed successfully in August and September 2013 in and around the site and cable route options. In parallel, there are a number of other surveys and assessments undertaken as part of the FEED and EIA process.

Public Exhibition

A well attended public exhibition was held on Wednesday 19th March at The Spyglass Inn in Ventnor where members of the project development team were on hand to assist in answering questions on the day.

Exhibition boards were on display showing different examples of what the demonstration site could look like and explaining how tidal arrays work.  To view the boards please click here.

Feedback forms were available at the exhibition to gather the local residents opinions on the proposals. Some of the comments captured are shown below:

  • “Best wishes for a successful application.”
  • “It is such a good idea and we must (as a community and society) start to do something useful with our natural energy.”
  • “It’s got to be the best option so needs to progress quickly”

All feedback from the exhibition was collated into a report and supported the planning application, which was submitted towards the end of November 2014.
