Introduction to Lanco Kondapally Power Ltd.

Lanco Kondapalli Power is an Independent Power Project (IPP) located at Kondapalli Industrial Development Area near Vijayawada in Andhra Pradesh, India. This Combined Cycle gas based Power Project is being developed in three phases. Total Capacity : 1466 MW Fuel Source (Natural Gas) : From GAIL (India) Ltd and M/s Reliance Industries Ltd

based on a long term contract Water Source : Upstream of the Prakasam Barrage on the River Krishna Plant Operations & Maintenance : Entrusted to M/s Genting LANCO Power (India) Pvt Ltd

(jointly owned by LANCO Infratech, India and Genting Group, Malaysia.)

Working of a Combined cycle Power Plant

1. Gas turbine burns fuel.

2. The gas turbine compresses air and mixes it with fuel that is heated to a very high temperature. The hot air-fuel mixture moves through the gas turbine blades, making them spin.

3. The fast-spinning turbine drives a generator that converts a portion of the spinning energy into electricity.

4. Heat recovery system captures exhaust. 5. A Heat Recovery Steam Generator (HRSG) captures exhaust heat from the gas turbine

that would otherwise escape through the exhaust stack. 6. The HRSG creates steam from the gas turbine exhaust heat and delivers it to the steam

turbine. 7. Steam turbine delivers additional electricity. 8. The steam turbine sends its energy to the generator drive shaft, where it is converted

into additional electricity.

Different Phases of Lanco Power Generation:

Phase I Capacity : 368 MW Status : Operational since October 2000 Project Specifications : The project has two Gas Turbines of GE Frame 9E, two

Heat Recovery Steam Generators and one Steam Turbine.

Power off-taker : Transmission Corporation of Andhra Pradesh Limited (AP TRANSCO) for 15 years, as per PPA

Phase II Capacity : 366 MW Status : Operational since December 2009 Power off-taker : Merchant basis Project Specifications : The power generated from stage II expansion plant is

evacuated through a dedicated 400 kv D/C transmission line connecting the power project with PGCIL - Nunna substation, located at about 20 KM from the power plant.

Phase III Capacity : 732 MW Clearances : All statutory clearances in place EPC Contractor : Lanco infratech Limited Status : 732 MW - is getting ready for operations As a backup arrangement, the company has created Naphtha Storage and handling facility for duel fuel operation of the plant. But due to some reasons the plant was inactive when we visited. They gave us an opportunity

to observe main sections of the plant like combustion chambers, Condensers, Heat Recovery

Steam Generator (HRSG), Boilers and Transformers. In the combustion chamber room there are

18 chambers for the combustion of gas.

In the way to Lanco power project we have visited Central Institute of Tool Design (CITD) at

Autonagar Vijayawada, where we learnt about CNC ( Computer Numerical Control ) and VLSI

design centre. They offer vacation courses on CAD/CAM/CAE. It is organized by the Govt. of

India Ministry of MSME.

Experience from the Industrial visit:

Exposure to better Industrial Practices.

See and know motto is more than read and learn.

After completing the Industrial visit we have upgraded our knowledge level.

They are following very strict rules regarding quality and safety.

During Industrial visit we are very much satisfied by acquiring knowledge and knowing

many things.

The Industrial visit helped us to know how to translate theory into practice.

We want to thank Lanco kondapalli and our beloved Principal sir and Vice principal sir for

providing us the opportunity to visit such a wonderful power project and motivated us to think

and work in a practical manner.

Thanking you,

Yours sincerely,

II & III Mechanical students,
