Electrical technology is used for generating, storing, regulating, transferring, and using electrical energy for solving different purpose in real life. Example: power plant generators, Air Conditioners, electric light bulb, Electric Fan, Electric Heater etc.

Conventional & Non-conventional ways of Electricity Generation:

Most electricity in the world is conventionally generated. Example: using coal, oil, natural gas, nuclear energy, or hydropower

Electricity is normally generated in Power plants.
Capacity of a Powerplant is the amount of electricity it can produce when it is running at full blast. It is other wise known as name plate capacity.
Name plate capacity or the maximum amount of power is typically measured in megawatts (MW) or kilowatts (KW).
The energy produced is defined in the units of KWh (Kilowatt Hour) or MWh(megawatts hour). It can be defined as:
Total KWh energy consumed= KWh rating X Number of hours it worked.
Capacity factor (net) of a Power plant: The ratio of the net electricity generated, for the time considered, to the energy that could have been generated at continuous full-power operation during the same period.
Example: Let a Powerplant has nameplate capacity of 3,942 MW & its annual generation was 31,200,000 MWh

Hydropower plants

Hydropower plants use water to generate electricity. When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower.
There hydroelectric facilities are powered by the kinetic energy of flowing water as it moves downstream.
Turbines and generators convert this kinetic energy into electricity, which is then fed into the electrical grid to be used in homes, businesses,
and by industry.
Tehri Hydropower Complex in Uttarakhand is the largest hydroelectric power plant in India with a capacity of 2400MW (Mega Watt)

Thermal Power station

A thermal power station is a power station in which heat energy is converted to electricity.
Water is heated into steam, which is used to drive the turbine of electrical generator.
After it passes through the turbine the steam is condensed in a steam condenser and recycled to where it was heated.
This is known as a Rankine cycle.
Coal has been used widely in thermal power station to heat the water & steam generation for decades.
Use of Gases have also increased now a days as an alternative of Coal because of its low price.
Vindhyachal Thermal Power Station in Madhya Pradesh is the biggest thermal power plant in India, with an installed capacity of 4,760MW.

Nuclear powerplants

Nuclear powerplants are also a type of Thermal Power plant.
Nuclear Power plant satisfies both economic and environmental protection goals.
So, the energy produced from Nuclear Power plant is a clean & green
energy.
Heat source for a Nuclear Power plant is the fission reaction of radioactive elements in a nuclear reactor.
This heat of nuclear reactor heats the reactor coolant which may be water or gas, or even liquid metal, depending on the type of reactor.
The reactor coolant then goes to a steam generator and heats water to produce steam.
The pressurized steam is then fed to a multi-stage steam turbine for electricity generation.
Uranium-238 (U-238) and Uranium-235 (U-235) are normally used as fuel for fission reaction
Kudankulam Nuclear Power Plant in Tamil Nadu is the highest capacity nuclear plant in India with an installed capacity of 2000 MW.

Nuclear powerplants

There are various Renewable Energy Sources also present which contributes for electricity generation.
The conversion of solar radiation directly into electrical power is done in Solar Power Plants.
Thermal energy is transformed into electrical energy using photovoltaic panels.
Large number of panels are installed in an optimal configuration and harvest light energy from the sun and convert it into electrical energy
which feeds into the grid.
Harvested thermal energy is converted into direct current (DC) electricity using solar panels.
To convert this direct current (DC) electricity to alternating current (AC) electricity, an essential component inverter is used.
Inverter is a component which converts direct current (DC) electricity to alternating current (AC) electricity.
Bhadla Solar Park of 2,250MW is India’s biggest solar power plant in the state of Rajasthan.
Wind mill converts the kinetic energy of moving air into mechanical energy that can be either used directly to run the machine or to run the
Induction generator to produce electricity.
Electricity produced from Tides of sea is known as Tidal Energy.
