Electricity Growth : 10%

Generation Capacity (MW) : 10,213

Maximum Generation (MW) : 7,556

Total Consumers (in Million) : 14.2

Primary Fuel Supply Options Gas: Only 16 TCF proven reserve. No significant gas discovery

in recent years. Depleting gas reserve restricts gas based generation expansion

Hydro: Present capacity 230 MW. No further significant potential Coal: Total 3.2 billion ton reserve in 5 mines. Mines are located

at dense populated area. Oil: Depends on importing. Renewable: Present capacity only 70 MW. High prospect of

solar.

Challenges

Huge demand supply gap causes regular load

shedding

High growth rate of electricity due to new

electrification & industrial growth

Fuel crisis due to depleting gas reserve

Arranging fund for investment

Scopes & Prospects

Efficiency improvement of existing power plants.

Fuel diversification.

Regional power trading.

Efficiency improvement of existing power plants.

Total gas based power plants: 6500MW

Average efficiency of gas based power plants: 30%

Efficiency of modern CCPP (Gas)= 60%

Possible output using same amount of gas= 13000MW
