    Power plant

    Power plant

    EspañolFrançais

    A power plant is an industrial facility that generates electricity from primary energy. Most power plants use one or more generators that convert mechanical energy into electrical energy[1] in order to supply power to the electrical grid for society's electrical needs. The exception is solar power plants, which use photovoltaic cells (instead of a turbine) to generate this electricity.

    Examples of Power Plants

    Coal-fired power plant.[2]

    Nuclear power plant.[3]

    Wind power farm.[4]

    The type of primary fuel or primary energy flow that provides a power plant its primary energy varies. The most common are coal, natural gas, and uranium (nuclear power). A substantially used primary energy for electricity generation is hydroelectricity (water). Other flows that are used to generate electricity include wind, solar, geothermal and tidal.

    Different countries get their electricity from different types of power plants. For example, in Canada, most electricity generation comes from hydroelectric power plants which accounts for about 60% of the total electricity generated in Canada.[5] Please see the data visualization below to explore how countries around the world get their electricity.

    Types of Power Plants

    Thermal

    Most thermal power plants use fuel to heat up water from a reservoir, which generates steam(usually at a high pressure). The highly pressurized steam then travels through pipes to rotate the fan-like blades of a turbine (see Rankine cycle for more info). As the turbine begins to spin, it causes giant wire coils inside the generator to turn. This creates relative (continuos) motion between a coil of wire and a magnet, which pushes electrons and starts the flow of electricity.[9]

    Fossil fuel power plants burn their fuel in order to create the thermal energy to run their external heat engines. A simple cycle gas plant does like the others: it works similar to a jet engine where natural gas is ignited and burned and the heat creates pressure that turns the turbine. Combined cycle gas plants use both the heat and steam as well. Types of fossil fuel plants include coal-fired power plants and natural gas power plants—accounting for the largest producers of electricity around the world (see data visualization below).Nuclear power plants use fission processes to generate electricity. In these plants, uranium nuclei are split which creates the thermal energy needed to create steam. It then works just like fossil fuel power plants where the steam spins a turbine, generating electricity. The power plants require the use of nuclear reactors to carry out these fission processes. Some types of reactors include pressurized water reactors, CANDU reactors, RBMK reactors, and boiling water reactors.Solar thermal power plants use heat from the sun’s rays to create the steam that is needed to rotate the turbine.

    Renewable

    Renewable energy power plants get their energy directly from their respective flows in order to generate electricity. These primary energy sources replenish themselves eventually, but are limited in the amount of energy that is available at any given time or place. Therefore they are often intermittent and non-dispatchable.[9]

    Hydroelectric facilities use energy from falling water in rivers and reservoirs to spin a generator and create electricity. This energy source tends to be more reliable (dispatchable) than other renewable resources, especially when the facility runs off of a reservoir.[11]Wind turbines get their energy from wind, which upon contact slows down and transfers kinetic energy to the turbine. Air drag causes the turbine to spin, and the maximum efficiency of turbines is given by the Betz limit.Solar panels use photovoltaic cells in order to create electricity. The incoming photons from the Sun hit atoms inside the panel's semiconductors which causes electrons to flow. Solar energy is intermittent but combined with energy storage technology their power can be much more reliable.

    Transportation of electricity

    Once electricity is generated, transformers "step-up" the electric power to a higher voltage in order to travel long distances with minimal energy loss. It then travels through "pylons" along overhead power cables to its destination, where transformers subsequently "step-down" the electric power to safe voltages for houses and utilities.

    Energy is an important requirement for us. From running our air conditioners to fueling our vehicles, our daily survival depends upon energy. Energy requirements have led countries to war and continues to be a bone of contention between many nations. Insufficient power (energy) supply is one of the main causes of crippling economies. Strong power generation industry indicates strong economic growth and prosperity for any nation.

    Energy comes in various forms. The most convenient of all of them is electrical energy. Not only is it easy to generate, but it can also be generated through a number of different ways with the help of different types of power plants. Although the word ‘generated’ is commonly used along with the term ‘energy’, it is a fact that energy cannot be generated or destroyed. We can just change the form of energy. At power plants too, energy that is available in a particular form is converted into another form.

    Different Types of Power Plants

    Nuclear Power Plants

    Nuclear power plants work on the chemical process of fission. Nuclear reactors are used to generate electricity. Fission is a type of nuclear reaction in which, when the atoms of certain elements called nuclear fuels absorb free neutrons, they split into two or more small nuclei and some free neutrons. In the process, large amount of energy is released. The free neutrons further strike the atoms of other fissile materials, thus setting off a chain reaction. The energy released from this chain reaction is harnessed to generate electricity.

    Nuclear power plants have ways to control or stop these reactions when they seem to go out of control and become threatening. The nuclear fuel used are Uranium-235 or Plutonium-239. Every country is in the race of becoming capable of harnessing nuclear energy. It is so because the free energy released by nuclear material is millions times more than that contained in an equal amount of any other traditional fuel. However, what raises the concern about these reactions is that a lot of radioactive material is created in the process. These substances remain radioactive for long. This raises the problem of managing nuclear waste.

    Records show that there are about 435 working nuclear power plants in the world. You must have heard and read about the 2011 Fukushima nuclear accidents. Managing the ‘used fuel’ at the plants and reducing the chances of threats involve high designing skills, extensive research and use of advanced technology. Moreover, nuclear power stations should be able to sustain a terrorist attack (large fires or explosions), as power stations are preferred targets of terrorist attacks. Thus, the operating cost or cost of setting up a new nuclear plant is likely to shoot up rapidly not only due to increasing costs of fuels but also due to the advanced technology required.

    Thermal Power Plants

    These power plants generate electrical energy from thermal energy (heat). Since heat is generated by burning fossil fuels like coal, petroleum, or natural gas, these are also collectively referred to as the fossil fueled power plants. Coal power plants were the earliest of the fossil power plants to have been built.

    Even today, coal is the most common fuel that is used by thermal power stations. The heat generated by burning the fossil fuels is used to turn a rotating machinery, most commonly a steam turbine or a gas turbine that changes the thermal energy into mechanical energy. The rotating turbine is attached to an alternator that coverts the mechanical energy of the rotating turbine into electrical energy. Handling and disposal of ash plays an important role in maintaining the environmental balance. These days, thermal power stations that use biomass or biofuel to generate electricity are being constructed.

    Hydro Power Plants

    These plants use the kinetic energy of flowing water to produce electrical energy. Hydro power plants store water in large reservoirs. Water in these reservoirs flow down the dam and rotate a turbine. As the blades of a turbine turn, so do the magnets inside the generator which is connected to the turbine. These magnets rotate past copper coils and with each rotation, electricity is produced.

    There are more than 2,000 hydro power plants in the US, making it the largest source of energy in the country. Despite their utility, their major drawback is that they are highly dependent on the hydrological cycle of the area where they are built. Less electricity is generated when the supply of water to the plant is insufficient. Some hydro power stations were shut down due to shortage of water.
