Manx Tidal Energy Ltd
Doing Renewable Business in the Isle of Man
• The Derillion Group has successfully been awarded three potential tidal
energy sites within the Isle of Man’s Territorial Waters.
• Manx Tidal Energy Ltd has been successful in obtaining the tidal
stream site in the North of the Isle of Man (Point of Ayre); The potential
energy from this site could initially be 120MW;
• Langness Tidal Energy Ltd has been successful in obtaining the tidal
stream site in the South of the Isle of Man (Langness Point); The
potential energy from this site could initially be 60MW;
• Kitterland Tidal Energy Ltd has been successful in obtaining the tidal
stream site in the South of the Isle of Man (Calf of Man Sound); The
potential energy from this site could initially be 30MW;
Derillion Energy Limited
• Derillion Energy Limited will be the new parent of the group’s renewable
energy projects. (Local Isle of Man Company)
• Derillion’s Asset Management Division will be responsible for the delivery
of the energy to the UK through a new interconnector.
• A new local company will be formed for this venture “MACS Link Limited”.
• The interconnector will be a state of the art 144kva AC – AC link with the
UK and will support multi-channel fibre optics. This will give the potential
for 200MW of power to be delivered in either direction.
Tidal Energy Types (wave and barrage)
1. Wave power, where devices lie on the surface and
are activated by wave motion. This is not what Manx
Tidal are doing!
2. Tidal barrage, where sea water on the incoming tide
generates power through turbines situated in the
barrage wall. Energy is then generated when the tide
recedes but sea water is retained and released over a
period to reduce the power surges. This is not what
Manx tidal are doing!
3. Wave piercing turbines. Similar to the 1MW turbine
in Strangford Lough which is visible at low tide. This is
not what Manx Tidal are doing!
4. Combination devices. In future it be possible to
incorporate these devices into the water column.

Tidal Energy Types (wave and barrage)
Tidal Energy Types (tidal stream)
1. Tidal stream or tidal current energy is generated
when the incoming tide moves millions of tonnes of
water across a series of sea turbines similar to wind
turbines but bottom mounted. Water is 832 times
denser than air so the torque of the incoming tide
turns turbine blades at depths of between 10-60m;
2. Tidal turbines vary in size and construction from 10kw
to 1.5MW;
3. They can be small, less than 5m in diameter, to the
larger turbines which are 27m tall with blade
diameters exceeding 20m;
4. They can be bottom mounted using piles or gravity
bases but can also be floating devices using flotation
chambers which hold them in the maximum tidal flow.

Point of Ayre
Tidal Stream Energy – Manx Tidal Energy
• Range from 2.5 to 3.5 m/s with several hotspots
in excess of 3.8 m/s using 1MW or 1.5MW proven
turbines;
• Area awarded for survey purposes is over
146sq/km;
• The whole area will be surveyed and hot spots
identified for seabed based turbine placement;
• Site relatively close to shore in an area with very
little other activity;
• The Port Facilities at Douglas or Ramsey will be
used for survey and later installation and
maintenance;
• Site has very little environmental activity based on
current survey reports.
Castletown
Tidal Stream Energy – Langness Tidal Energy
• Smaller shallower site suitable for smaller
seabed turbines and/or mid mounted turbines;
• Access to grid within four kilometres;
• Tidal speeds from 2.5 m/s to 4 m/s according
to current surveys;
• Access to Port facilities in Castletown or
Douglas;
• Extensive business park areas close by for
research on turbine dynamics;
• Greater environmental issues for EIA;
• Totally invisible.
Calf of Man
Tidal Stream Energy – Kitterland Tidal Energy
•Smallest site to be used for turbine development
purposes;
•High environmental impact with extensive
wildlife and topographical issues;
•Use of low impact environmentally friendly
technology;
•Tidal flows of 2.5 m/s to 3.5 m/s in certain areas
but 8 m/s in selective areas;
•Possible conflicting tides;
•Area of outstanding beauty requiring careful
planning and development;
•Totally invisible.
MACS LINK Limited
Interconnector
•The cable route is being explored with a view
to delivering upwards of 180MW direct to UK
using AC cable;
•AC/DC conversion on Island if required for
battery storage purposes;
•Spare capacity of 50MW in initial phases
which could be utilised for solar arrays;
•Energy delivery under appropriate subsidy
regime;
•National Grid options under discussions;
•Technology partners chosen and initial
funding in place.
Method of transmission (land)
1. Cables will be required to bring power from the
turbines to an onshore transmission building where
they can be amalgamated into one, two or possibly
three AC cables for an outward route to the UK;
2. The cables will arrive on shore on the North East of
the Island for the Northern site under the beach and
travel in trenches to a site (yet to be determined) to
the transmission hub and control rooms;
3. None of the sea route cables or the land cables will be
seen and they will all be trenched at least 2m under
the sea bed or under the beach. There is no chance
of snagging;
4. A similar land based exercise is required when the
transmissions cables arrive in the UK.
Benefits to the Isle of Man
1. No cost to the Island. The Manx Government is not investing
financially in this venture, all funding coming from private or
institutional investors or lenders. However, they are providing
Government time resource;
2. Seabed lease income. The Manx Government benefits from sea
bed leases which are based on power generated and exported to
the UK;
3. Other fees and benefits. In addition to the sea bed lease the
Manx Government will benefit from licencing fees and local
company fees;
4. Employment will be generated on the Island through
administrative services, local engineering services involved in
assembly of the devices, installation of the devices and
maintenance of the devices over the 50 year lease period;
Benefits to the Island (cont)
1. Educational and vocational training opportunities;
2. Engineering input from local business;
3. Marine Services. A dedicated vessel/vessels will remain in Manx
waters with a Manx crew to assist in the installation, maintenance
and removal (decommission) of the turbines;
4. Research and development of more efficient or more
specialised turbines or tidal devices will be conducted on Island;
5. Project expansion. Subject to local opinion it may be possible to
extend the energy in the water column by adding wave devices;
6. Invisibility. The whole project is invisible unlike other types of
renewable energy and is predictable well into the future
guaranteeing revenue streams;
7. Reputation. The development will be one of the largest privately
funded tidal projects in the world.
Obstacles and Challenges
1. Technological issues. Tidal energy is still regarded as an
emerging technology in a hostile environment;
2. Subsidy and UK Government issues. The UK Government
have recently severely reduced the subsidies of onshore solar and
onshore wind and are not seen by the industry as renewable
energy friendly;
3. Environmental Impact Assessment issues including Basking
sharks, whales and dolphins, seals and other marine organisms.
Whilst the Northern area is free of fishing, horse mussels and
scallops there may be issues in the Southern sites;
4. Planning, Until very recently there was only draft planning
legislation for the seabed. This week the Marine Planning Bill was
issued. This needs to be passed before work can start in earnest.
