What is power plant?
A power plant is a facility that converts the energy of fuels into electricity. The term power plant is often used to refer to a coal-fired, nuclear, natural gas, or oil-fired electric generating station. Power plants are typically large industrial facilities that provide enough electricity to supply an industrial town or city. The diesel power plant is a bit exception from some other power plants. It is because the diesel engine is used as the prime mover and the alternator is coupled with it. The alternator rotor rotates with the diesel engine shaft and generates electricity. However, let’s explain how diesel engine generate electricity.
Diesel power plant working process
How diesel engine generate electricity? The diesel power plant working process is not complex as nuclear and steam power plants. A diesel power plant is a type of power plant which produces electricity by burning diesel fuel in a diesel engine. Diesel power plants are typically more efficient than natural gas-fired plants and emit less air pollution. Diesel engines are the most common type of internal combustion engine in the world, and they’re used in both on-road and off-road vehicles.
The heat is generated in a diesel power plant by burning diesel fuel in a combustion chamber. The pressure created by the heat is used to turn water into steam. The steam then turns a turbine that generates electricity. They work by burning diesel fuel to drive pistons, which turn a crankshaft that drives an electrical generator or alternator that produces electricity.
On the other hand, diesel generators are used in many different industries but their most common use is in the construction industry. Diesel generators provide power to construction sites when there is no power grid available. They are often used by mobile homes, remote campsites, and other places where people need electricity but can’t get it from the grid. Diesel generators are also popular among large construction companies because they produce more power than gas-powered generators and they can be fueled with diesel fuel which is cheaper than gasoline or natural gas.
What is not found in diesel power plant?
All the power plant or electricity generating station is similar to some other power station but something becomes different. A steam power plant is a type of power plant that is used to generate electricity by heating water and to turn it into steam. The following are not found in diesel power plants:
- Coal
- Gas
- Nuclear fuel
Why diesel is better than gasoline?
Diesel engines are more fuel-efficient than gasoline engines. Diesel has a higher energy density than gasoline, which means that diesel engines are used to generate more power for the same weight. In addition, diesel has a higher cetane number, which is an indicator of how quickly it reacts with air to produce combustion. This means that diesel is easier and quicker to ignite than gasoline – so it starts faster and will continue running even if it momentarily stops receiving fuel. However, there are some key ways that compel to choose diesel instead of gasoline.

- It has more energy density than gasoline.
- Diesel is cheaper than gasoline.
- Diesel engines are more efficient in terms of fuel consumption and CO2 emissions.
- The exhaust gas from diesel engines contains fewer pollutants than gasoline engines.
- Diesel engines are more fuel efficient and have a higher energy density than gasoline engines.
Why diesel power plant is not used as base load power plant?
Diesel power plants are not used as base load power plants because they are not reliable. They do not produce electricity consistently and they cannot be operated at constant speeds. Cost is a major issue. We know that diesel is costly if we use diesel to generate bulk power to meet our load demand. Then the per unit electricity cost will be so high that it may go out of reach from the consumers.
However, to be a base load power plant, diesel power plants need to have a high capacity factor, which is the ratio of how much energy is produced to how much energy could be produced if it were operating at full capacity all the time. Coal-fired power plants have higher capacity factors than diesel and natural gas-fired generators. This is because coal-fired plants can run at constant speeds without variation in output.

Is diesel power plant costly?
Diesel power plant construction is lesser than steam and nuclear power plants but running cost is so higher than some other power plants. Diesel power plants can be costly because they are more expensive due to the high cost of fuel. Diesel power plants are more expensive to build than natural gas plants. Normally, diesel is costly fuel around the world. Diesel power plants require a lot of fuel which makes them more costly to operate. Diesel power plants emit more CO2 than natural gas plants.
Final thought
Diesel power plants are cost-effective, reliable, and easy to maintain. They are also relatively simple to operate and can be started up quickly when needed. Diesel power plants produce less pollution than other sources of energy, such as coal or natural gas. However we have told about how diesel engine generate electricity and we hope this discussion may give you a better idea about the diesel power plant electricity generation process, why it is not suitable for base load, and many more.
