SP Transmission
Delivering Infrastructure for Renewables
Colin Taylor
Head of Transmission Programmes
Large Increase in offshore & onshore wind generation
Base case investment delivers MWs and boundary capacity in line with Gone Green scenario
Increased import capacity will further enhance security of supply for Scotland
Flexibility to fund investment over and above Gone Green if required
Delivering Energy Policy
Majority of 275kV network over 40 years old
£1.3bn (~ 65%) of investment provides connections & capacity for wind generation
Strong Incentives for Delivery - By 2020 we will:
Increase transmission capacity to England to 6.6GW (now 2.8GW)
– a further 2.GW+ (ECHVDC) triggered by submission to Ofgem
Connect a further 2.5 GW of wind generation (total of 4.4GW ) to align with Gone Green
scenario - revenue driver to fund up to 7GW if required
15% of our substation assets renewed
Replaced over 800 circuit km of overhead line
– modern transformers and conductors increase transfer capability
£0.8bn (~ 35% )of investment needed to modernise the network by 2020
Significant sections of 132kV network over 60 years old
Investment Plan based on nationally agreed central scenario (Gone Green)
RIIO-T1 Overview
Meeting the Delivery Challenge
Using the latest technologies • Getting the most out of existing assets
• Installation of shunt and series capacitors
• Use of advanced inter-tripping technologies to facilitate higher transfers
• HVDC “bootstraps”
Market • Developing the capacity and capability of the supplier base
• Attracting new suppliers
• Changing the contractual model
People • Developing existing staff and recruiting staff with the necessary skills
• Significant graduate and apprentice programmes to grow our own workforce
• Increase in staff focused on transmission activities since 2011 of circa 200
Stakeholders • Government communities and landowners
• Strong focus on consents with Scottish Government
• Close liaison between SO and TOs
• More flexible approach to land rights, encourage engagement from developer at
early stage

4c. East Coast & Central Upgrade New 400kV circuits from Denny to
Wishaw. Includes 17km new OHL
Bonnybridge to Airdrie.
Pre-construction – Project to complete 2018
• Pre-engineering and environmental works well
advanced
• 2018 date aligns with SHETL programme
• Incremental capacity through central
Scotland of 600MW.
5. Western HVDC Link 400kV link to from Hunterston in
Ayrshire to Deeside in Wales
Construction – To complete 2015/16
• Main contracts let
• Ongoing landowner discussions at Hunterston
• 2200MW capacity link
• Enhances both export and import
capacity
6. Eastern HVDC Torness - Lackenby HVDC. Part of
Eastern HVDC
Scoping
• Multi-terminal options being assessed by
NGET/SPT/SHETL
• Circa 2000MW capacity link
• Enhances both export and import
capacity
7. Dumfries & Galloway Upgrade 175km of new 275kV OHL from
Harker to Auchencrosh.
Scoping
• Pre-engineering and environmental works
underway
• Facilitates 2000 MW of renewables
• Remove 45km 132kV OHL
• Enhance security in D&G
Key Activities and Challenges for 2013
• RIIO-T1 provides a robust framework for investment
delivery
– stable mechanism to fund investment
– strong incentives on output delivery
• We have made the most of our “fast-track year”
– recruitment, market development, engineering
– good progress on project delivery
– major focus on consents
• We are committed to continuous improvement in our
engagement with all stakeholders
– TOs, SO, DNOs
– Government at all levels
– Developers
