Key trends driving power generation sector
5
EnvironmentalNeed for environmentally
benign solutions
SocialNeed for business modelinnovation
Significant buildup in Thermal capacity over last several years
Demand for uninterrupted power demonstrated by use of DG; UPS- Inverters
Renewables
Growing need for renewableintegration
Power GenUnserved need foruninterrupted 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
TechnologyChanging landscape likely to
have an impact on turbines
Challenges with alternate technologies Limited Storage Hydro, CAESconstrained
Flywheels, super capacitors not suitable for 3-4 hour operation
PolicyNeed for gas based peakersrecognised
Gas allocation planned to create 2 GW peaking capacity by 2012-17 in cities
General Tariff increases planned, but no differential tariffs
