Strategic Decisions:
• Decentralization of O&M : zones / districts / circles
• Centralization of Commercial processes & Consumer
Services
• Commercial Business Processes Re-engineered
• CAPEX Program of Approx. Rs. 2000 Crore till FY 2008-09
(Load Growth, Loss Reduction, System Improvement &
Infrastructure Development)
• Network & Process Automation Road Map defined
(SCADA, GIS, GSAS……..)

The GIS centric system
integration makes use of
location specific information
through other systems.
System Integration majorly
requires:
Sharing attribute
information with other systems
like CRM and ERP.
Data delivery to other
systems like DMS and OMS

Challenges Ahead
Segregation of Challenges Strategic Challenges
Business Challenges
Power Availability at competitive cost
Reduction in AT&C Losses (overachievement of
regulatory targets)
Uninterrupted & Quality power supply
Enhancing Public perception with regard to service
delivery
Regulatory uncertainty
Operational Challenges
Performance based regulation
Cost control in line with MYT Targets
Competitive scenario post 2007 for high end consumers
HR ChallengesCost Saving Vs Quality of Man-Power
Talent Management for the future competitive scenario
•BA man-power quality
•Safety
•Multi-cultural integration
•Inter-regional corridor constraints
Power Procurement : Started 01-04-2007
• Interesting facts in Aug’09
Out of 96 time slots of 15 min each for a day, increase in
demand w.r.t 08-09 up by average 35% and 50-55% in
some slots.
Increase in demand w.r.t previous day (upto 20-27% in
many slots)
Average energy consumption per day in 09-10 is ~ 22%
higher w.r.t. last FY
Average Peak Demand is ~30% higher w.r.t last FY
Approx. 15 MUs purchased through power exchange at
rates between Rs. 4.50 to 15.43 per unit
• Power Procurement (Bilateral, Banking, Power Ex.) in 09-
10 ~ 580 MUs Approx. 20% of total power consumption in 09-10
