7. POWERGRID & Grid Management  Modernisation of Regional Load Despatch Centres (RLDC) / State Load Despatch Centres (SLDC) by POWERGRID  Implementing State of the Art Unified Load Despatch & Communication (ULDC) Schemes for overall improvement  Manpower  Manning of RLDC by Senior personnel  Training of RLDC & SLDC personnel on regular basis  Procedures  GRID CODE  Availability Based Tariff  All these resulted into:  Significant improvement in System Parameters  Merit Order Operation, Leading to Overall Economy  Improved grid performance Improved grid performance  Increased intra and inter-regional Power Exchange and Trading

8. Philanthropic Approach of POWERGRID  POWERGRID developed and implemented “Environment and Social Policy and Procedure (ESPP)” document in wide consultation with Public, Environmentalists, NGOs and Multilateral Funding Agencies; the only Power Sector Utility to do so  In Talcher Project, too, implementation of Environment and people friendly Social Policy and Procedures  Minimization of forest stretch – only 20 Km in 1,400 Km  Electrification of villages under rural electrification programme  Electrification of more than 30,000 villages is the states of U.P., Bihar & West Bengal  Modernising power supply system in the institutions like BHU, IIT Kharagpur on no profit no loss basis  Improved power supply as well as training centre for modern supply system  Consultations with public in villages Consultations with public in villages  Development of villages Development of villages

10. Important Features  Talcher II (2000 MW) Generation Project : First inter-regional project for transfer of total power from Eastern to Southern Region  Transmission System  2000 MW, (+/-) 500 KV, High Voltage Direct current (HVDC) bipole line from Talcher to Kolar; Longest HVDC link in Asia (more than 1400 Km.)  About 750 Circuit Kms. of Alternating Current (AC) transmission lines for dispersal of power beyond Kolar  Transmission Project Cost & Commissioning Approved Actual Project Cost 3865 Crore 3100 Crore Commissioning 42 months 33 months Schedule

11. Unique Features of the Project  Vast Transmission System  Total steel used : 90,000 MT  Total conductor used : 16,000 Kms.  State of the Art HVDC terminals for conversion from AC to DC  Software based controls, protection and Man-Machine Interface System  Design and execution very challenging due to various rivers crossing enroute (Mahanadi, Vamsadhara, Godavari, Krishna and Pennar)

12. Important Features  Project conceived with Debt : equity ratio of 80:20 Rs. In Crore A.Equity 772 B. Debt3093 TOTAL (A + B)3865  World Bank loan was considered for AC portion only as per available resources  Supplier’s Credit considered for HVDC portion

14. OverviewOverview  Investment approval took 33 months;  Feasibility Report submitted in July 1997  Investment approval obtained in January 2000  Less time left for execution  To minimize project implementation cycle, pre-execution activities undertaken in parallel with investment approval  WorldBank loan tied up in April’ 98 for AC portion  Bids were invited and processed based on World Bank funding. Bidders entitled to Deemed Export Benefits under WB fundingDeemed Export Benefits

15. OverviewOverview  Funds tie up with World Bank held up due to economic sanctions  Funding constraint had the potential to delay the project.  Innovative approach to proceed with procurement process was adopted:  by seeking special dispensation in Dec.’98 from Govt. of India for availing Deemed Export Benefits  seeking approval of World Bank for retroactive funding

16. Surmounting Challenges  In July 1999, GoI granted a special dispensation after persistent follow up  Clearance was obtained from WB for retroactive financing at a later date and meanwhile, Rs. 675 Crore also raised through domestic sources in lieu of World Bank Loan  Rs 1,000 Crore of Suppliers credit raised for HVDC portion without sovereign guarantee or any back up guarantee mainly on POWERGRID’s own financial strength

18. ChallengesChallenges  Execution time of the project got reduced from 48 months to 42 months to match with generation  Time Schedule was tight considering the size of the project  Mid-way during the execution, NTPC advanced the commissioning of its first 500 MW unit putting tremendous pressure on POWERGRID  Acute Right of Way Problems considering the spread over a vast expanse of about 2000 km Acute Right of Way Problems considering the spread over a vast expanse of about 2000 km  Difficult Terrain and Varied Soil Conditions  Challenging Law and Order Situation  Need to evacuate surplus power from ER to energy deficit SR.

19. Surmounting Challenges  Extra-Ordinary Measures Undertaken for timely execution of project  Unique Project Definition Manual developed  Standardized foundations and tower designs : saved 12- 18 months  Standardized bidding document and Systems & Procedures Contracts awarded within months from the date of project approval by GoI Inspite of all the constraints right from the inception of the project, POWERGRID completed the project 9 months ahead of schedule and at a cost lesser by Rs. 700 cr.

20. BenefitsBenefits  Project commenced operation before generation project and surplus power of about 1500 MUs alone could be transferred prior to generation project  Total of about 12,000 MUs transferred from ER to SR from September, 2002 to September, 2004.  About 5000 MUs of surplus power  Balance 7000 MUS from Talcher II Project  Significant improvement in grid performance in SR  Grid frequency improved from 48.0-48.5 Hz to 49.5-50.5 Hz  Substantial improvement in voltage level (typically Bangalore)  Loss Reduction in SR ; Benefit Rs 290 Crore  Saving of Rs. 1500 Crore to SR on account of availing surplus power, thus postponing immediate investment  ER benefited on account of reduction in fixed charges of generation
