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

What is the Solution?

Generation close to Loads

reduce T&D losses

Utilize Gas for Peaking andmid-merit Domestic + LNG

Create Policy incentives topromote peaking investment

Base load Nuclear + coal

Natural gas Peakers
