Standard Proposal Module for 3x660 MW Coal based Thermal Power Project
Power Crisis has been a long clamor in India and this seems to persist for the
coming decade or so. Beyond optimistic illusions, ground realities are too
fierce to be accepted.
Seeds of improvement are however being planted at all possible arenas
broadly Indicating: -
The Project Idea springs from one of the reforms Viz. generation of Power.
To cater the accelerated need of the country Ultra Mega Power Plants
(UMPPs) have been proposed. These are giant power plants of 4000 MW at
one place. In addition to these, a number of Mega Power Projects (More than
1000 MW) are also being promoted. The unit size of power plants has also
experienced a supercritical shift in technology. Thus focus is on more efficient
supercritical units of 660 MW and 800 MW. However considering imported
coals as the main fuel, unit size can go up to 1000 MW. As the domestic coal

available for power sector is having very high (40 to 45%) ash content
feasibility of higher size units are yet to be examined. Meanwhile after
500MW / 600 MW (subcritical) the next suitable supercritical size was
decided 660 MW or 800 MW for coal based thermal power plants.
This Project has been based on study and formulation of EPC proposal of
3x660 MW coal based thermal power plant (Super Critical Technology). It
also includes plant design basis, scopes of work different packages &
technical write up of main plant as well as Balance of Plants.
Cost estimation and percentage cost breakup of the Thermal power plant
spells out the brief overview of the EPC project cost.
The study shall form the basis for the standard proposal module for the 660
MW project. As the gear of technology is experiencing a critical shift in
power sector, India is keen to welcome the Supercritical technology. The first
stage of capacity shift is seen to be 660 MW which is being adopted by NTPC
and other private sector players for several upcoming projects.
The assignment covers supply of complete main plant with BOP package on
Engineering, Procurement and Construction (EPC) basis and making standard
proposal module of this. EPC work can exclude civil works, coal handling
system, ash handling system, external raw water system and water intake
system depending upon the projects.
The power plant configuration considered for the project shall be having 3
identical units to generate gross power 1980 MW.

There were some limitations with respect to the analysis and data that may
affect the accuracy of the results:
EPC Proposal depends largely on Bid Requirements so may be some
sections may not be as applicable.
This is only a rough cost estimate and may differ from prevailing market
conditions.
As EPC has three models BTG+BOP, Total EPC, STG+BOP, hence
scope of work and cost estimation can vary from project to project.
Some costs components like Land, Transportation etc. can vary
depending on site location.

Standard Proposal Module for 3x660 MW Coal based Thermal Power Project
Growing economies always need a proportional need for power. Country like
India has a required growth in power sector close to 15 %. In order to match
the accelerated need of country, there is urgent need is to take the challenge to
squeeze the time and cost required to complete a coal based power project. If
some more R&Ds could fetch some reductions in total EPC costs and could
increase operating efficiencies, it would be a great relief to fund hungry power
projects.
We should go for large size projects which are more efficient and less
polluting than several smaller units. One more field which needs to be
prioritized is Risk management and project management that play a very
crucial role in carrying out such big projects.
