Power Generation in 2008-09 & Requirement in 2010
At present, Indias total installed power capacity stands at 1,47,402.81MW. Of this, the contribution of each sources are
Hydro - 36,647.76MW
Nuclear sources -4,120 MW
Renewable energy -13,242.41 MW.
Indias power generation capacity 68% below target in 2009.
There is a huge demand for power in FY10.It is expected to grow by 4.6% with a capacity of 7,730 MW are likely in FY10.

Types of Power Plants
Mechanical Energy Electrical Energy
Thermal Station: The turbine is rotated by steam which is produced by the heat generated by burning fuel in a Boiler.
Hydel Power Plant: The mechanical energy is produced by inducing high pressure water through a nozzle onto the turbine.
Nuclear Power Plant: Nuclear power is power (generally electrical) produced from controlled (i.e., non- explosive) nuclear Reactions i.e. fission or Fusion.
- 4. The coal is brought and crushed to powder. This is feed to Boiler for producing heat
In Boiler the water is converted to steam.
In Super heater the moisture content is removed from the steam and that steam is called super heated steam
The superheated steam rotates the shaft of the High pressure turbine
The Exhausted steam is sent to preheater and the steam then rotates the Intermediate pressure(IP) Turbine
The steam from the IP turbine is then feed to low pressure turbine.
The turbine shaft is connected to the Generator, which produces Electric Power.
The power generated is then Transmitted.
- 5. Thermal Power Plant
Power plant order is placed on EPC contract, which is divided into 2 parts
Balance of plant 40% of total contract value
60% of total contract value
Boiler, Turbine & Generator
- BOP includes supply , erection and commissioning of complete plant excluding Boiler, Turbine & Generator.
