1 Electricity interconnectors – next generation Martin Crouch Future Energy Strategies seminar 3 July 2012

2 2 Agenda Ofgem’s role How much interconnection? Regulatory framework Is interconnection a good thing?

3 3 Average total import capacity relative to installed generation capacity by percentage, 2004 (Source, DG Competition Report on Energy Sector Inquiry, 2007) Interconnection from Great Britain: the context 2012 figure: 4.8%

4 4 Policy context – an electrical island Existing Construction Planned/ possible But less so in future

5 5 Energy Infrastructure Package: Interconnection capacity to support 2020 RES targets UK now = 3.5GW EIP proposal = 6.6GW (Source: Imperial College & KEMA, study for EIP communication, 2010) 2020

6 6 Source: ECF – Roadmap to 2050 (www.roadmap2050.eu) UK + ROI 2010 = 2 GW ECF pathways = 21GW ECF 2050 Pathways: Interconnection capacity to support 80% RES by

7 7 Agenda Ofgem’s role How much interconnection? Regulatory framework Is interconnection a good thing?

8 8 Potential for commercially viable interconnection –But pure merchant financing of projects less viable … –We want to see timely development of new infrastructure to contribute to the delivery of internal energy market Financing gap- greater need for 3 rd party investors? Need for a common / coordinated approach to regulation of shared assets Challenges with merchant-exempt regime: –Regulated “risk” of exemptions, which are seen as the exception not the rule –European model, national TSOs deliver interconnector investment Drivers for change  Need to develop a regulatory regime to remove regulatory barriers and facilitate investment

9 9 The regulatory framework will take into account the commercial viability of a project as well as considering the wider benefits efficient levels of interconnection can offer to consumers for example: security of supply, integration of renewable energy sources, competition and market integration across Europe, Consumers should be protected from the cost implications of excessive returns or market power that might accrue to interconnector owners, Developers should be able to earn returns that are commensurate with the levels of risk they are exposed to under the regulatory framework, Regulatory treatment of developers should be coordinated between NRAs at either end of the shared asset and (For GB and new interconnector developments) Regulatory treatment should allow third party developers and should be impartial and unbiased between TSOs and non-TSO developers, existing and future developers Regime principles

10 10 Inetrconnectors derive their revenues (congestion rents) from auctioning capacity at different time horizons Recoup returns within bounds of pre- set cap and floor Returns over cap – paid back to consumers Returns fall below floor – triggers payment from consumers Allows revenue regulation, protects consumers from market power Maintains element of market valuation of interconnection Within the regulated regime favoured by Third Package The Cap and Floor approach

12 12 Two real examples that demonstrate the benefits of interconnection Example 2: National Grid can call on interconnectors to assist in emergency situations The Moyle Interconnector was offline between June 2011 and Feb 2012 This resulted in an additional £20 million constraint costs for National Grid in Scotland (excess wind power in Scotland could not be exported to N Ireland) Example 1: Interconnectors can reduce the cost for National Grid to manage the system The IFA Interconnector provided 30% of the emergency assistance used by National Grid to meet a 3.5 GW shortfall in Feb 2012 – this helped avoiding problems in GB X Moyle IFA

13 13 48 Hypothetical concerns

14 Hypothetical concerns...

15 15 Benefits of interconnectors are likely to be higher if... 1.Interconnected countries have different generation and demand patterns – asymmetric shocks + access to diversity of generation sources and reserve 2.The GB price respects and reflects the physical constraints of the GB transmission system as well as scarcity – our price needs to signal when we need more energy and where we need it 3.Good cooperation between neighbouring TSOs and full implementation of internal market rules
