  1. Welcome Shri Brajesh Mishra Principal Secretary to Hon’ble Prime Minister April 08, 2004

  2. POWERGRID started its commercial operation in 92-93 First ISO 9001 Company in Power Sector It operates and maintains 50,000 ckms of EHV transmission system along with 81 S/Stn at 99.25% system availability Over 40% of the total generated power is wheeled by POWERGRID Such a performance is feasible through Robust system design after detailed studies with thrust on integrated development Deployment of Hot line Maintenance Techniques Use of Emergency Restoration System Trained and Dedicated Manpower with decentralised administrative powers POWERGRID, the central transmission utility

  3. Commercial Performance Key Financial Indicators (Rs. In Crores)

  4. National Grid of 30,000 MW capacity planned for execution by 2012 with an investment of Rs.71000 Crore. Phase I : 5000 MW completed in 2002 Phase II: Additional 18,000 MW Planned to be completed by 2007. 3500 MW already commissioned Phase III: Additional 7000 MW Planned from 2007-2012 POWERGRID to finance up to Rs 51,000 Crore through IR and loans Balance Rs 20,000 Crore through Private Investment or GoI’s additional grant / equity with matching loan Future Plan

  5. The only company to adopt ESPP document with wide consultation at National and International level POWERGRID: First to assist wherever disaster struck Gujarat Cyclone (1998) Orissa Cyclone (1999) Gujarat Earthquake (2001) Establishment of Green Sub Station Establishment of ultra modern office, Group Housing Society, School and Township Organise training on regular intervals for SEBs LENDING TENDER HANDS

  6. NR NER ER WR Inter Regional Links 500 MW 500 MW 1200 MW 500 MW 2000 MW 1000 MW Present IR Capacity : 8500 MW To Go Upto 30,000 MW by 2012 SR

  7. Functions of ULD&C • Apex body for integrated Grid Operation • Responsible for Optimum Scheduling and Dispatch of Electricity • Supervise and Control Inter-state Transmission System • Ensure Security and Economy in operation as per the Grid Standard and the Grid Code • Keep accounts of Electricity transmitted through the Grid

  8. ULD&C PROJECTS : TYPICAL HIERARCHICAL CONTROL CENTRE SETUP SLDC SLDC SLDC SUB LDC SUB LDC SUB LDC RTU RTU RTU Level NLDC National Region 5 Nos. ERLDC SRLDC NERLDC WRLDC NRLDC 32 Nos. State HQ Group of Disticts 51 Nos. Plant / SS 1160 Nos.

  9. ULD & C Projects : Objectives • Greater and deeper visibility of the Power System under Control • Dedicated real time communication and co-ordination between various control centres in the region • Effective management of grid parameters like frequency, voltage etc and better grid security through various SCADA / EMS features resulting in better • Operations Scheduling • Operations Monitoring and Control • Power System Analysis • Real time dispatcher training

  10. Establishment of Modern ULD&Cs has Resulted into • Considerable betterment of System parameters viz. frequency and Voltage in spite of Minimal Generation addition • Merit Order Operation leading to overall economy • Introduction of ABT (Availability Based Tariff) linked to frequency variation • Transparency in Grid Operation • Quantum leap in Intra and Inter Regional power Trading • Enhanced Grid Discipline

  11. POWERGRID’s Diversification in Communication • To utilise spare capacity of ULD&C Schemes through an incremental investment • To lay 20,000 kms telecom network spread over 60 cities including metros and major cities • 12,000 kms, connecting 30 cities already commissioned . Rest by June’04. • Telecom Network on Transmission line is sturdy and secure, rodent menace free, Vandalism proof, 100% availability etc. • DWDM /SDH equipment deployed • Scalable to terra bit capacity • Obtained IP-II licence in Jan 2001 and ISP category A licence in May 2003
