Marine Development
Marine - Site Development
SSE Marine Development Overview• Develop, build, own and operate • Utility scale tidal (inc. barrage) and wave sites• Focusing on Ireland and GB• Diversifying renewable portfolio• Applying offshore wind experience to marine• Dedicated development team
• resource assessment• technology evaluation• site development experience
• Largely technology neutral approach
Focus on Ireland and GB – the best marine resource in Europe
Marine - Site Development
Case study – UK Pentland Firth Round• Launched by Crown Estate - Sept 2008• First commercial marine leasing round in World• Deliver MW’s, socio-eco benefits and technologies• 1.2GW announced 16 March 2010• SSE interest 800MW
• 2 sites technology aligned with partners• OpenHydro• Aquamarine
• 2 sites technology neutral
Going Forward....• Secure commercial technologies • Learn from Pentland• Seek further opportunities in home markets• Partnering
Marine Technology Development
Marine technology development – learning through experience
SSE Experience• Over 7 years experience & £15m invested• Why?
• Demonstrate market pull• Practical experience• Synergies with other SSE activities• Investment return
• Learning points• More money & time required!• Market very fragmented• Installation & maintenance biggest challenge
Case Study – Aquamarine Power’s Oyster• Independent Co (SSE a shareholder)• Deployed Oyster 1 – 325kW – 2009• Accessible – generation on-shore• Survivable – naturally ducks!• High capture factor• Promising power to weight ratio
Lessons so far ?
• Consents & Permissions• Environmental Impact Assessment
• Planning consents• Seabed owner options/leases• Marine Spatial Planning• Deploy and monitor
• Technology• No commercial technology – yet!
• Promising concepts – signs of consensus• Entry of major OEM’s?• Transition from R&D to commercial?
• Government • Government has central role
• Co-operation and partnering key to lowering risk

• Networks upgrades to facilitate move from 1GW – 7GW renewables
• Increased links to islands
• Increased interconnection with UK e.g. Norway
Major Network investment plan focused on facilitation of renewable power
Why Transition to Smart Grids?
Changing demands on grid
• Increased demand for energy
• Increased Renewables
• Increased price volatility
• Increased interconnection
Maintaining existing grid capability
• Reliability and quality
• Stability
• Market efficiency
• Environmental concerns
The challenge is to balance the need for Complex networks vs Security of supply
SSE activities in Smart Grids
• Intelligent Loads – distributed storage
• Electrical Vehicle Pilot Schemes – London, Oxford, Cardiff,
• Smart Metering – 28,000 pilot customers, Onzo meters
• Special Protection Schemes – protecting networks
• Active constraint management
Diverse involvement in Smart Grids
• 6 miles off North-Scotland
• 11,500 customers• Existing generation a mix of wind, wave
and gas
• Limited interconnection to mainland
• High level of wind generation vs demand
• Choice of moratorium on more
renewables or operate grid differently
• 4 year research project between SSE and
University of Strathclyde to develop
scheme to facilitate increased connection
of renewables

Case Study – Active Constraint Management – Orkney
Need to operate Grid differently
• Software and hardware solution for:
• Multiple generators
• Multiple constraints within the network
• Limits on export cables
• Unique features:
• Real time active network management
• Real time measurement and control
• Zonal approach to constraint allocation
• Existing connections unaffected
• Last In First Out (LIFO) access principles
• System installed and live Nov. 09
• Additional generation already being connected
(30% increase over previous maximum)
