2. Introduction
 A thermal power station is a power station in which heat
energy is converted to electricity. Typically, water is heated
into steam, which is used to drive an electrical generator.
 Mundra Thermal Power Station is located at Mundra
in Kutch district in the Indian state of Gujarat.
 The power plant is one of the coal-based power
plants of Adani Power.
 The coal for the power plant is imported primarily
from Bunya, Indonesia.
 Source of water for the power plant is sea water from the Gulf
of Kutch.
 It is the world's 11th-largest single location coal-based thermal
power plant as well as India's second largest operational
power plant after NTPC Vindhyanchal.

3. Specifications
 Capacity
 Plant capacity is 4620 MW, comprising of 9 units with 4
units of 330 MW and 5 units of 660 MW.
 The 330 MW units are based on sub critical technology and
the 660 MW units are based on supercritical technology.

4.  Design and development
 The Mundra plant sets global benchmarks for power producers in terms of
size, efficiency and sustainability.
 Despite its enormous capacity, the facility stands unique in the world when
compared with area per MW.
 Located on a very optimized layout of 734 Acres alongside auxiliaries like
cooling towers, 47 MLD desalination plant and flue gas desulfurization plant.
 Power Evacuation
 To help the state and region utilities evacuate electricity from the plant and into the grid, Adani
Power had constructed two power lines.
 The 433 km, 400 KV transmission line to transmit 1000 MW from Mundra to Dehegam in
Gujarat.
 The 989 km, 500 KV high voltate Direct current (HVDC) bipole line with the capacity to
transmit 2500 MW from Mundra to mohindergarh in the northen state of Haryana.

5.  Fuel
 At full load, the plant consumes about 55,000 mt of coal per day,
though its yearly consumption is between 16 and 17 million mt.
 It runs on blended subbituminous coal, about 70% imported from
the Adani coal mine in Bunyu, in Indonesia’s East Kalimantan
province, and the rest from the public sector Mahanadi Coalfields
in the eastern Indian state of Odisha.
 Water
 Mundra is India’s largest TPP to function off a sea-water based
closed- cycle induced draft circulating cooling water system.
 The system draws on sea water that is recycled upto 4 times,
conserving water & requiring a smaller discharge pipeline into the
sea than an open- circuit cooling system.
 Though seawater is used for the cooling system, other Auxillary
systems use sea water purified by a reverse osmosis plant, that can
produce 47 Million litres of fresh water every day

6.  Ash Management
 They established and commissioned an Ash bagging unit to
achieve 100% Fly Ash utilization.
 Each machine has an operational capacity of 18 TPH and
the unit operates three such machines giving it a total
capacity of 54 TPH.
 Environmental Controls
 The FGD system, supplied by Alstom India, requires only
seawater as the adsorbent (no alkaline chemicals) to reduce
sulfur emissions.
 Its simplified structure comprising an adsorption tower,
seawater supply pump, and aerator renders operation and
maintenance (O&M) easy.

7.  Advantages
 Making Energy from Thermal Power plants is easy.
 The fuel used (coal) is cheap.
 Thermal Power Plant can be set up anywhere near fuel and water supply.
 It requires less space as compared to the hydroelectric power station.
 Disadvantages
 As thermal power plants involve the production of large amounts of smoke and fumes, these affect the
atmosphere.
 The overall efficiency of the power plant is low.
 The maintenance cost is expensive.
 The water requirement for maintaining the temperature of the turbines is too much.

8.  Conclusion
 At present thermal power plant generation accounts approximately 70% of the total amount of
electricity produced around the world.
 Thermal power generation, which uses fossil fuels, causes more CO2 emission than other
power generation method.
 We should optimize development of coal fired thermal power plant in geographical clusters
 Promote the development of thermal power plant in coastal areas.
