The power plant has generators that convert power from a mechanical source, such as a heat engine or hydroelectric turbine, into electrical energy. To deliver the electrical energy long distances requires a network of very long transmission lines. The long distances requires power at a very high voltage. Voltage, or "electromotive force" is the force that pushes the electrical current through the wires.
The high voltage is produced by a transformer in an electrical substation that is located very close to the power plant. The transformer changes the voltage produced by the gnerator, which is usually about 15,000 volts, to hundreds of thousands of volts. The electricity is transmitted, hundreds, even thousands of miles on high voltage transmission power lines. Near the school, the transmission line is connected to another substation. This substation has a transformer that changes the hundreds of thoursands of volts of the transmission line down to a much lower voltage, usually below 20,000 volts.
The lower voltage power is delivered to customers on electrical distribution lines, owned by the local utility company. Near the school is another transformer. This transformer changes the distribution voltage to a much lower voltage for direct use inside the school. The voltage of the power used in the school is usually between 120 volts and 480 volts, and there is usually other Transformers in the school to change the electrical energy to voltages specifically required for ventilation motors, lights, computers, copiers, kitchen appliances, etc.

What type of energy transformation occurs in a nuclear power plant?
In a nuclear power plant, nuclear energy is transformed into heat energy through nuclear fission. This heat energy is then used to produce steam, which drives turbines connected to generators to produce electricity. So, the energy transformation in a nuclear power plant is from nuclear energy to heat energy to electrical energy.
How does a diesel power plant works?
A diesel powerplant uses the diesel power cycle for energy generation. A diesel power plant is one using a diesel engine to run a generator coupled to it. A generator produces power when it rotates.
Is a nuclear power plant an example of kinetic or potential energy?
A nuclear power plant is an example of potential energy. The energy stored in the nucleus of an atom is released through nuclear reactions to generate power.

What happens in an energy source?
In an energy source, such as a power plant or a battery, energy is converted from one form to another. For example, in a power plant, mechanical energy from a turbine is converted into electrical energy. In a battery, chemical energy is converted into electrical energy.
