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

What is the Solution?

� Generation close to Loads –reduce T&D losses

� Utilize Gas for Peaking and mid-merit – Domestic + LNG

� Create Policy incentives to promote peaking investment

Base load Nuclear + coal
