  1. Electricity Interconnectors in GB 26.02.13 Emmanouela Angelidaki

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

  5. ECF 2050 Pathways: Interconnection capacity tosupport 80% RES by 2050 2050 Source: ECF – Roadmap to 2050 (www.roadmap2050.eu) UK + ROI2010 = 2 GW ECF pathways = 21GW

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

  7. Proposed electricity interconnector investment

  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. 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. CAP AND FLOOR APPROACH • 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

  11. CAP AND FLOOR APPROACH

  12. Timeplan for NEMO 2013-2014 2017-2018 2018 2014-2017

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

  15. Regime Design
