1 Electricity Interconnectors in GB Emmanouela Angelidaki

2 2 Content Role of interconnection in Europe and GB Approach to interconnector investment to date and drivers for change New regulatory regime for interconnector investment in GB Next Steps Q&A

3 3 Interconnection-the basics Interconnection (IC) =Cross border transmission, connecting different member states European legislation: leading role on how revenues are raised (i.e. Profits can be made) It requires all interconnector capacity to be allocated via market based methods, i.e. Auctions Interconnectors generate revenue based on the price arbitrage opportunity between countries. Whilst there is a country price difference, there will be demand for the capacity & a revenue stream will be generated In GB, to date, investment could take place only through the merchant route, i.e. investors would take the full upside and downside risk and would seek for an exemption from EU legislation, to protect their business case; We are now developing a regulatory regime which can facilitate economic investment …

4 4 European 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

5 5 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

6 6 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%

7 7 Proposed electricity interconnector investment

8 8 Drivers for change Increasing government support for IC investment and Ofgem’s commitment to facilitate economic and efficient IC investment, while maintaining the developer-led approach 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 3rd party investment? 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  Need to develop a regulatory regime to remove regulatory barriers and facilitate economic and efficient investment

9 9 Steps to date January 2010: Consultation on options for regulating interconnector investment September 2010: Next steps letter on our intention to progress with the cap and floor regime, using project NEMO as the pilot project June 2011: Consultation on principles and design of the cap and floor regime, exploring whether this regime could be a high level solution for other IC projects December 2011: Preliminary conclusions on the principles and design & Ofgem’s intention to develop a process for considering other IC investment proposals and to ensure the three GB regimes for transmission investment are compatible (offshore, onshore, interconnection)

10 10 Recoup returns within bounds of pre- set cap and floor Revenues over cap – paid back to consumers Revenues 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 CAP AND FLOOR APPROACH

11 11 CAP AND FLOOR APPROACH

12 12 Timeplan for NEMO Phase 1 (Investment decision): Provisional decision on C&F levels based opex &capex forecasts Phase 2 (Construction): NRAs receive all bids and justification for preferred bid Phase 3 ( Post- construction): Ex-post review of actual capex & re- forecast of opex; final C&F levels Phase 4(operation): 25 year regime, revenues assessed against C&F every 5 years

13 13 Proposed approach for setting the cap and floor returns Will be set out in our consultation, expected to be published in March Aim: identify risks associated with IC investment and then develop an approach for setting the CoC for IC investment under the cap and floor approach; The proposed approach is developed for a notionally efficient investment structure and it aims to answer questions like: –Separate CoC at the cap and the floor vs. single CoC central estimate for the project; –Mechanistic vs. Discretionary approach –CoC parameters fixed at financial close vs. post construction –Cross Jurisdiction considerations: blended CoC vs. Separate calculation in each currency

14 14 Next Steps Consultation on our proposed regime, including the CoC methodology: March May 2013 Analysis of responses and review of design and methodology: June-September 2013 Decision on NEMO provisional cap and floor returns: Q4 2013

16 16 AspectDesign MechanismCap & floor returns earned within boundaries; revenues above cap returned to consumers, revenues below floor require payment from consumers (via Transmission Use of System Charges) Regime length20-25 years Cap and floor levelsLevels set ex-ante and remain fixed for regime length Set on basis of costs, using RAV based model Setting costsCapex – ex post capex review* Opex – set ex-ante, ie before operation Cap and floor profileFlat in real terms Assessment period (assessing whether IC revenues are above/below cap/floor) 5 years, discrete periodic basis Availability incentiveSymmetric financial incentive linked to the cap, based on actual vs. target availability, target set on a project by project basis *(for NEMO; consultation will explore alternative treatment for future projects) Regime Design
