1 Marine Renewables in Orkney and The European Marine Energy Centre (EMEC) Jeremy Baster Director of Development Services Orkney Islands Council

2 The Orkney Islands: NW periphery of Europe

3 The Orkney Archipelago - 17 inhabited Isles Population: 20,000

4 The Age of Oil: the Flotta Terminal North Sea Oil from pipeline to tanker

5 Orkney s wind turbine history Costa head turbine erected in the early 1950 s by the North Of Scotland Hydro Electricity Board. Blew down in a 200 kph hurricane in 1953.

6 Huge resources Note: 3D volume of spheres is proportional to the level of energy available

7 Large exploitable capacity Energy category Current energy use R & D Existing/approved wind Acceptability scenario High Medium Low Installed generation capacity (MW) Tidal current Offshore wind Offshore wave Onshore wind (1 MW units) Tidal head Coastal wave Energy efficiency Micro-renewables Biomass crops Biomass harvest Bio-digestion Energy from waste Total installed capacity (MW) Annual power production (GWh) Energy income ( M@1.2p/kWh) ROC income ( M@4.6p/kWh) Tidal current Offshore wind Offshore wave Onshore wind Tidal head

8 Tidal Energy - Potential Locations

9 EMEC s Mission: To be the internationally acknowledged leading test and certification centre for marine energy converters.

10 Sponsors: Scottish Executive Scottish Enterprise Highlands & Islands Enterprise Orkney Enterprise Carbon Trust Orkney Islands Council DTI EU (Tidal) Around 15M

11 Wave Site Billia Croo Where are we now?

12 Test Centre - Schematic Diagram

13 Progress World s first floating wave energy converter generates to grid Ocean Power Delivery - Pelamis

14 Floating Main Types of Wave Devices Overtopping Oscillating Water Column Hinged Flap Underwater Buoyant

15 Where are we now? Tidal Site Falls of Warness, Eday

16 Eday Tidal Site Falls of Warness Current velocities = 7.2 knots (flood) 6.5 knots (ebb) at spring tides

17 Progress Scotland s first tidal turbine - inaugurated 28 September 2007

18 Types of Tidal Devices Horizontal axial-flow, bottom mounted Horizontal axial-flow, surface piercing Horizontal axial-flow, floating Vertical axial-flow Other designs include: Oscillating Hydrofoil, Air Injection Technology and Lagoons

19 Orkney Grid Existing Wind Turbines 10MW Approved Wind Turbines 16MW EMEC 7MW 20MW Cable X 2 SCOTLAND Orkney Minimum consumption 6MW (maximum consumption 30+MW) Flotta Oil Terminal 10 MW gas-fired Minimum consumption = 6MW + export via single cable = 20 MW = 26 MW - local generation potential = 27 MW

20 Scotland s Existing Electricity Transmission System

21 Transmitting Orkney s Electricity At present, Orkney is at the end of the centralised system, on the left We are here We need to be here It needs to be at the other end, on the right, to exploit the renewables potential

22 Island Infrastructure Problems * a privatised energy industry, including transmission system; + a regulator (Ofgem) charged with protecting consumers; = an inability to provide infrastructure unless there is demonstrable and immediate demand (to avoid stranded assets ) therefore difficult to develop infrastructure for the regions and difficult to develop infrastructure for emerging technologies (marine renewables) and expensive to use the infrastructure if generators are seen as distant from consumers, rather than consumers as remote from energy source

23 Our Vision Orkney Power Station TWh of clean energy Energy capture Energy production Energy export Direct supply of electricity From wind Energy conversion and storage H Y D R O G E N By cable From wave Back up from offshore gas By pipeline From tide Plus any imports By tanker

24 Europe s future offshore Super-Grid?
