1. WELCOME HIS EXCELLENCY Mr. SAHBAN F. MAHJOOB Minister of Power GOVERNMENT OF IRAQ & The Delegation

2. Indian Power Grid – its Evolution Phenomenal expansion since Independence  Generation : 1349 MW 101,866 MW (in 1947) (in 2001)  Grid : Local grid – at the time of Independence. State Grids – emerged in 1960s. Regional Grids – in 1970s. Five Regional Grids – Northern, Western, Southern, Eastern & North-eastern National Grid – under progress.

11. NORTHERN REGIONAL POWER SYSTEM Salient features  Largest in geographical area amongst the five regions covering 30.7% of the area and 28% of the country’s population.  Maximum variation in weather conditions from severe cold to peak summer.  Large distances between generation centers and load centers and power is transmitted over long distances.  Availability of Hydro generation reduces drastically in winter months.  Largest number of constituents (8 states/UT’s, 3 Central Generating Companies, one Central Transmission Utility and Bhakra Beas Management Board).

12. NORTHERN REGIONAL POWER SYSTEM Salient features  Establishment of the first super thermal power station (Singrauli STPS) and 400 kV transmission system in the country.  Establishment of the first High Voltage Direct Current (HVDC) long distance transmission system in the country (2x750 MW, + 500 kV Rihand-Dadri HVDC bipole).  First HVDC back-to-back interconnection with Western Region (2x250 MW back- to-back HVDC station at Vindhyachal).  First 400 kV Static Var Compensators (SVC’s) in the country (2x + 140 MVAR SVC at Kanpur).  Largest capacity of combined cycle gas power stations amongst the five regions (2480.47 MW) located along the 700 Kms. long Hazira-Bijaipur-Jagdishpur (HBJ) natural gas pipeline of GAIL.

15. Grid Operation by POWERGRID Earlier performed by personnel from Central Electricity Authority on the platform of REB Transferred to POWERGRID in stages -SRLDC 1994 -ERLDC1995 -WRLDC1996 -NRLDC1996 Overall improvement in grid operation since takeover by POWERGRID

16. Overall Improvements by POWERGRID oBetter hydro-thermal mix through objective & rational Scheduling. oBetter merit order operation enhancing the overall efficiency. oEffective use of transmission lines and enhanced utilisation of their capabilities, retaining stability margins. oBetter commercial practices. oImprovement in grid parameters (e.g. voltage, frequency profiles). oBetter utilization of Inter-regional links. oInfused the grid discipline. oLower backing down of Power plants.

19. Overall Improvements by POWERGRID oOptimum capacity utilisation oBetter co-ordination among constituents. oTransparency in grid operation. oDocumentation of Grid Code, Regional operating Procedures, Black Start Procedures etc. oIntroduction of modern State-of-the-art technology in grid operation. oBetter communication facilities oIntroduction of modern SCADA & EMS scheme (ULDC)
