Technical & Economic Feasibility Study for Mozambique Regional Transmission Backbone Project (“CESUL”) Key challenges encountered • Challenges to successful realisation of CESUL and the associated large (hydropower) generation developments include: – Project size and remoteness / distances involved Klicka här för att ändra format på underrubrik i bakgrunden – Technical requirements (to ensure high availability & reliability) – Cost competitiveness compared to alternative regional options – Amount of financing and commercial frameworks required – Integrated nature of generation and transmission developments, requiring alignment of stakeholder interests and high degree of coordination • Other key considerations include: – Devising transmission solutions in support of initial generation developments while facilitating long-term expansion to tap Mozambique’s energy potential – Ensuring sustainability and tangible benefits to local (Mozambican) economy from recommended technical and economic solutions – Minimising environmental & social impacts through line route selection – Dynamic and iterative nature of planning, analysis, structuring and financing © Vattenfall AB Technical & Economic Feasibility Study for Mozambique Regional Transmission Backbone Project (“CESUL”) Findings and Conclusions • Feasibility Study confirms technical viability of combined HVAC and HVDC transmission backbone solution for 3,100 MW (and more) power transfer capability • CESUL Phase investment costs (excl financing costs and IDC) are estimated at US$ 2,119Klicka million US$ 1,800 for Stage 1) här(of för which att ändra format på million underrubrik i bakgrunden – Phase financing requirement of ~US$2,780 million incl IDC & price contingency • Economic viability of combined hydropower and transmission backbone is robust • Financial viability and competitiveness of delivering electricity at Mozambique / South Africa border in southern Mozambique appears promising – Timely realisation of Mphanda Nkuwa project is key to commence CESUL development – Realising Cahora Bassa North Bank will allow complete CESUL Phase development – Cost of debt financing to be tested with market participants • HVAC solution will ensure interconnection of Mozambique’s national transmission grid, with increased access to electricity along line route • HVDC portion of transmission backbone is scalable – for initial CESUL Phase solution and beyond • Due to magnitude of project costs, a staged Phase realisation should be considered • CESUL development needs to continue without delay from early 2012 to align with planned timeframe for commissioning of hydropower project(s) © Vattenfall AB Technical & Economic Feasibility Study for Mozambique Regional Transmission Backbone Project (“CESUL”) Recommended CESUL Phase solution • CESUL Phase includes combined HVAC & HVDC solution • HVAC solution includes: • • 1,340 km 400 kV AC line for 900 MW continuous power transferKlicka

Project (“CESUL”) CESUL Feasibility Study – Institutional & Operational Aspects 49 © Vattenfall AB Technical & Economic Feasibility Study for Mozambique Regional Transmission Backbone Project (“CESUL”) Envisaged organisation of CESUL • CESUL Project size, technical nature and complexity, as well as the very large financing requirements, are all factors indicating that CESUL should be established as a Special Purpose Vehicle (“SPV”) härand för att ändra format på underrubrik bakgrunden – SPVKlicka model recommended structure willi be developed by CESUL Financial & Legal Advisors – EDM is expected to be lead Sponsor – Additional equity participation may be sought from credible international investors with relevant skills, experience and financial strength • Organisation structure, staffing and training programme for CESUL SPV should be clarified early to mitigate against operational risks • CESUL SPV will be granted long-term Concession under Mozambique law – Terms and conditions of the Concession need to be confirmed, including a Transmission / Wheeling charge methodology supportive of limited recourse project financing structures (part of mandate of Financial & Legal Adviser) – Relationships to EDM (as National Power Transmission Grid Manager), HCB, Motraco and other stakeholders must be clarified and formalised to ensure timely implementation of CESUL ©

Feasibility Study for Mozambique Regional Transmission Backbone Project (“CESUL”) 52 CESUL Feasibility Study – Conclusions & Recommendations 53 © Vattenfall AB Technical & Economic Feasibility Study for Mozambique Regional Transmission Backbone Project (“CESUL”) CESUL Feasibility Study – Conclusions CESUL is found to be technically and economically viable Recommended Phase design is a combined HVAC (400 kV) and HVDC (500 kV bi-pole) solution with high reliability, at a total cost of US$2,119m (funding requirement of ~US$2,780m), providing a transmission capacity >3,000 MW Klicka här för att ändra format på underrubrik i bakgrunden HVAC solution will ensure interconnection of central and southern parts of national grid, allowing for economic & social development along line route Phase solution is considered economically and financially robust, based on large-scale export of hydropower to South Africa, with significant revenue to GoM Phase facilitates implementation of MPNK and CBNB, with both projects found to be economically and financially viable in combination with CESUL solution HVDC portion of CESUL Phase can be implemented in two stages, allowing for staggered realisation of MPNK and CBNB if required (with MPNK assumed to be the first major hydropower development) Phase implementation is expected to take 59 months (of which 42 months construction time) Financing requirements for CESUL Phase are significant, with need for close coordination of generation and transmission developments to manage commercial and timing risks CESUL can be expanded by adding 2nd bi-pole with capacity of 2,650 MW © Vattenfall AB Technical & Economic Feasibility Study for Mozambique Regional Transmission Backbone Project (“CESUL”) 54 CESUL – Recommendations and Next Steps i Based on a targeted commercial operations date for MPNK by 2017, CESUL project preparation work has to commence early 2012 by progressing design, procurement and contracting arrangements Klicka här för att ändra format på underrubrik i bakgrunden ii In parallel, recommended legal, financial and commercial structures and arrangements need to be finalised iii Financial close of CESUL should be targeted for mid-2013 (to align with generation project timeframes) iv Early confirmation of CESUL equity sponsors (in addition to EDM) will be key to successful development v Timely and coordinated engagement with South Africa (Government and Eskom) will also be essential vi Consideration may be given to creation of a Mozambique Joint Coordination Committee for CESUL and associated hydropower projects © Vattenfall AB Technical & Economic Feasibility Study for Mozambique Regional Transmission Backbone Project (“CESUL”) 55 Obrigado / Thank you for your attention! com energia
