Peak Deficit – Choked by growth
Peak Demand (MW)
Maharashtra
• Peak deficits are a constraint on GDP Growth
• Losses to GDP estimated at 5-6%
• Industrial Losses estimated over Rs. 42000 crores

Key trends driving power generation sector
5
Environmental Need for environmentally benign solutions
SocialNeed for business model
innovation
▪ Significant buildup in Thermal capacity over last several years
▪ Demand for uninterrupted power demonstrated by use of DG; UPS- Inverters
RenewablesGrowing need for renewable integration
Power GenUnserved need for
uninterrupted power
Trends Highlights
▪ Increasing disposable incomes demanding better quality of life
▪ Significant part of retail consumers used to subsidized electricity
▪ Growing concern on NOx in cities- DLN mandatory in Delhi (25 ppm)
▪ Water availability a growing concern in cities
▪ Need to integrate growing number of renewables into the grid – especially wind
▪ Ancillary markets and associated products likely to evolve
Technology Changing landscape likely to
have an impact on turbines
▪ Challenges with alternate technologies – Limited Storage Hydro, CAES constrained
▪ Flywheels, super capacitors not suitable for 3-4 hour operation
PolicyNeed for gas based peakers recognised
▪ Gas allocation planned to create 2 GW peaking capacity by 2012-17 in cities
▪ General Tariff increases planned, but no differential tariffs
