Transcription de la présentation

  1. DEVELOPMENT OF SOUTH ASIAN GRID

  2. WHY SOUTH ASIAN GRID ? • Optimal Utilization of Natural Resources • Opportunity of Energy Trading • Economy of Scale • Advantage of Peak diversity • Minimization of Environmental Damages

  3. SOUTH ASIAN COUNTRIES : COMMON FEATURES • Abundant reserves of Natural resources • Low per capita electricity consumption • Deficit of Power & Fast Growth in Demand • Common frequency of operation • Similar voltage class

  4. SOUTH ASIAN COUNTRIES : ENERGY RESOURCES • Bangladesh – Dominated by natural gas • India – Dominated by Coal • Bhutan – High dependence on hydro • Nepal – High dependence on hydro • Pakistan – Largely petroleum and natural gas • Sri Lanka – Dependence on petroleum

  5. SOUTH ASIAN COUNTRIES:EXPLOITATION OF RESOURCES In order to capture the benefit of resource sharing, as experienced all over the world, SARC Countries should also move forward collectively and explore the various possibilities. • Large scale trading of coal and natural gas is limited due to constraints in its handling & transportation. • Hydel energy can be traded through transmission network only. • Therefore for bulk exchange of energy building up of a strong transmission network is the need of the day.

  6. FEASIBILITY OF INTERCONNECTION • India is centrally placed sharing boundaries with SAARC Countries. • Vast Interconnected transmission network. • Development of Strong National Grid on the Anvil.

  7. INITIATIVE FROM INDIA TOWARDS SOUTH ASIAN GRID

  8. INITIATIVES FROM INDIA • Initiatives/Control for Power exchanges at governmental level. • Encouragement for setting up of new projects on sharing basis to harness natural resources. • Continued exchange of energy based on bilateral agreements.

  9. ONGOING POWER EXCHANGE : INDIA AND NEPAL • Over 16 links at 132/33/11 kV level. • About 50 MW of power being exchanged. • Net export from INDIA to NEPAL is around 10% of total demand of Nepal. • Supply of free power from Tanakpur (India) to Nepal – 70MU/annum.

  10. ONGOING POWER EXCHANGE : INDIA AND BHUTAN • Interconnections with Chukha HEP through 220 kV Chukha-Birpara 3 ckts and all surplus power from Chukha is exported to India. • Presently, this constitutes 75% to 80% of total power generated at Chukha.(1400MU/year) • Earning to Bhutan - Rs. 140 crores/Annum. • Part of this power re-exported to Bhutan to meet radial loads closer to Indian border. • Kurichu HEP (4x15 MW) of Bhutan is also connected to Indian Grid (Salakati) at 132 kV.

  11. SOUTH ASIAN GRIDTHE FUTURE PROSPECTS

  12. South Asian Grid - India and Nepal • Nepal expected to be surplus in power by 2002 • 3 nos. 132kV lines under construction between India & Nepal • Butwal(Nepal) – Anandnagar(India) • Birgunj(Nepal) – Motihari(India) • Dalkebar(Nepal) – Sitamarhi(India) • Large potential projects being considered for development and export of power to India • West Seti HEP 750 MW • Arun HEP 685 MW • Pancheshwar HEP 6,500 MW • EHV links planned for evacuation of power to India • West Seti – Bareilly – Muradnagar 400 kV line • Arun HEP – Muzaffarpur 400 kV line • 400/765kV lines from Pancheshwar HEP to India

  13. South Asian Grid - India and Bhutan • Interconnection being established at 400kV level from Tala in Bhutan to Delhi in India for evacuation of power from Tala HEP(6x170MW) • More hydro projects to come up in Bhutan • Wangchu : 900MW • Bunakha : 180MW • Sankosh : 4060MW • Power from these projects also to be imported by India

  14. South Asian Gird - India and Bangladesh • East Zone of Bangladesh(generation dominated) shares border with the Eastern Region of India • Bangladesh can supply power to Eastern India • West Zone of Bangladesh(load dominated) shares border with the North-Eastern Region of India • India can supply power to Western Bangladesh • 2 nos. of 220kV links,one at each side, initially envisaged for limited exchange of about 150 MW • Krishnanagar(Eastern India)-Ishurdi(Western Bangladesh) • Shahjibazar(Eastern Bangladesh)-Kumarghat(N-E India)

  15. South Asian Gird - India and Bangladesh • There are proposals to set up Gas projects by IPPs for selling power to India • Scheme evolved for importing 1000 - 1500 MW power from Gas projects in Bangladesh • Establishment of a S/s at Krishna Nagar in West Bengal through LILO of Farakka-Jeerat 400 kV D/c line • Gen. station - Ishurdi (Bangladesh) 400 kV 2xD/c • Ishurdi - Krishna Nagar (India) 400 kV 3 ckt. • Krishna Nagar - Jamshedpur 400 kV D/c • Jamshedpur - Rourkela 400 kV D/c

  16. South Asian Grid – India and Myanmar • Govt. of Myanmar had proposed to develop Tamanthi HEP (12x100MW) across the river Chindwin • About 700 to 800 MW power from this project might be transferred to India • Myanmar shares boundary with North-Eastern Region of India • 400kV links proposed for evacuation of power into India • Tamanthi – Badarpur – Misa – Siliguri line

  17. South Asian Grid – India and Sri Lanka • Proposal for interconnection of Sri Lanka with Southern Regional Grid of India under discussion • Usage of HVDC bipole or HVDC back-to-back in conjunction with AC lines suggested

  18. SOUTH ASIAN GRIDTHE ISSUES TO BE ADDRESSED

  19. Issues to be addressed : Techincal Firming –up the availability of power i.e. . • Quantum of power available for exchange • Periodicity of availability/Allocation of firm power • Identification of Reliability criteria. • Establishing the feasibility of interconnection. • Choice of interconnection and technology, considering – Right of way, Cost, Equipment availability etc.

  20. Issues to be addressed : Operation of Interconnection • Operating Code • Establishment of Operating Code by the participating countries • Commercial arrangements • Pricing of power • Payment Security Mechanism • Terms for Indemnification • Sharing of International Experience for Bulk Power Exchange

  21. Issue to be addressed : Legal • Legal arrangements • Firming up of procedures for dispute settlement and Arbitration • Applicability of Laws of Respective countries/ International Laws • Institutional Arrangement • Identification/ Creation of Common Agency to regulate, Administer and Operationalize the Interconnection on long term basis • Establishment of Co-ordination Centres to Govern the Operational matters on Daily and Short Term basis

  22. Issues to be addressed : Financial possibilities of funding arrangement • Multilateral Funding • Private Investment In either case following aspects are to be considered: • Sale/ Purchase of Power on a sustained/ long term basis • Security of Payment / Signing of Covenant • Immunity to Political Changes and changes in Law
