The selected application is GEOTHERMAL
POWER PLANTS
Justification:
❑ Geothermal energy is a renewable energy source created from the heat
generated by the earth's internal core and is available 24-hours a day, 365 days a
year. Geothermal energy poses no indication that it will be going away anytime
soon. The earth has been producing heat from its liquid iron core for millions of
years, and it will continue to do so into the future. Combined with the reusing
and reinjecting of water into geothermal reservoirs, geothermal energy is a
renewable energy source that could be utilized for many generations into the
future.
❑ Many geothermal power plants use a reservoir to store hot water that can be
turned into steam to spin turbines to generate electricity. When the water levels
in the reservoir begin to deplete, water can be reinjected into the pool to keep
the plant running at a high capacity at all times. Aside from routine shutdowns for
maintenance, geothermal power plants are available to generate electricity more
than 90% of the time during any given year.

Choice of a one RES with proper justification
Here renewable energy system is Solar pv based utility power plant.
Justification:
❑ The burning of coal, oil and natural gas is accompanied by waste flue gases, harmful to the environment
as these contain toxic chemicals. Apart from polluting the environment, heat to the extent of 60% is
released into the atmosphere, contributing to the elevating global warming levels.
❑ Approximately one ton of CO2 is emitted per MWh (Megawatt-Hour) of energy. It means that a super
thermal power station of 2000MW would generate 2000 tons of CO2 every hour or 48,000 tons of
CO2 every day.
❑ Thermal power plants have an installed capacity of 234GW, out of which 124GW is by coal-based plants.
This can release up to 2976 thousand tons of CO2 per day into the atmosphere.
❑ Renewable energy use not only replaces conventional power but also reduces it to the extent of 40%.
This is because solar and electrical-based systems are more efficient than conventional fuel-based systems.

❑ A few years back, the country's power generation depended mainly on coal-based super
thermal power plants where each cluster could generate up to 4000 to 5000 MW. The
power generated would then be fed to the national grid for widespread distribution. There
are several such super thermal power plants across the country. In plants like these, coal is
burnt to produce heat, which then boils water, generating superheated steam. This steam
would pass through a turbine, connected to a generator. Lastly, the power generated would
be dispatched to the switchyard for transmission to the power grid. In some plants, oil or
natural gas is tapped as a substitute for coal. However, coal, oil and gas, all the three are
dwindling resources.

❑ As of now, Solar power generation in India is 40.09GW. Contribution by Karnataka (7.1GW),
Telangana (5GW), Rajasthan (4.4GW), Andhra (3.47GW), Gujarat (2.654GW) and the
remaining by other states are significant. The target for renewable energy by 2022 is
175GW which includes 100GW for Solar, out of which 40GW is earmarked for rooftop grid-
tied Solar and off-grid. In addition to that, work is in progress for setting up several Ultra
mega Solar power plants on the PPA model in many states with investment by the private
sector.
