RGTPP is located near Ramgarh Town district head quarter, Jaisalmer (Rajasthan), which is largest district of the state. Its installed capacity at about 60 km from is 270 MW. And this plant is located in largest state of India, based on area There was problem in maintaining desired quality standards in electric supply to Jaisalmer on account of excess losses because of longer transmission lines. To rectify above problem and to utilize available natural gas in this area RGTPP was established in this border district whose existing capacity is 270 MW.

ABSTRACT
I have completed my summer training from Ramgarh Gas Thermal Power Plant, Jaisalmer.
In this report the main emphasis is on the power generation process.In the starting of this
report the introductory aspects of RGTPP all over India has been covered. Later I have
explained the principle of operation and basic equipment used for the generation of
electrical power.
Recognizing its excellent performance and vast potential, government of the India has
identified RGTPP as one of the jewels of Public Sector ‘Navratnas’- a potential global
giant.
Inspired by its glorious past and vibrant present, RGTPP is well on it’s to realize its vision
of being “A world class integrated power major, powering India’s growth, with increasing
global presence”.
A combined cycle power plant produces high power outputs at high efficiencies (up to
55%) and with low emission. In a conventional power plant we are getting 33% electricity
only and remaining 67% as waste. By using combined cycle power plant we are getting
68% electricity. The basic principle of the combined cycle is simple: burning gas in a gas
turbine produces not only power – which can be converted to electric power by a coupled
generator – but also fairly hot exhaust gases.
