Power plants are a key element in production processes, ensuring the continuity of industrial processes. In fact, they allow companies to operate without interruptions, avoid losses, meet their production goals, and prevent short- and long-term economic impacts.
Currently, power plants in Bogotá and other cities across the country have become an increasing requirement in homes and businesses due to frequent power outages and weather events. Below, we explain the most relevant aspects of this equipment and its role in Colombian industry.
What is a power plant?
A power plant, also known as an electric generator, is a machine that produces electricity through a generator and an internal combustion engine. This system functions as an electrical backup, transforming mechanical energy into electrical energy in the process.
Power plants in Medellín and other regions of Colombia are commonly used when there is a shortage of electricity or during power outages, ensuring continuity of work in production processes. One of the most frequent uses is to generate electricity in places where there is no quality power supply, it is intermittent, or it does not exist at all.
Power plants have different specifications:
- Engine type: indicates the type of fuel to be used and the type of internal operation performed by the engine. It also indicates its maximum power, usually in horsepower.
- Load size: the most common are between 8 and 30 kW for domestic systems and between 8 and 3000 kW in industry.
- Number of phases: single-phase or three-phase, although some systems can be designed with more phases to reduce ripple and provide more accurate currents.
- Duration: refers to the guaranteed operating time at full load.
- Type of cooling system used by the equipment.
- Weight: value in kilograms and dimensions to fit the installation site without problems.
What are the benefits of having an electric generator?
One of the most notable benefits is related to continuous production processes, as a power plant guarantees uninterrupted production in the event of a power failure. The following advantages are also obtained:
- Reduction of economic losses: when there are no process stoppages, the financial impact on industries is avoided.
- Greater electrical reliability: Electric generators provide more than one source of energy, which increases the integrity of the electrical system.
- Extra income: Through the Voluntary Disconnectable Demand (DDV) program for companies, reliability and stability are provided to the country’s electrical system and, as a result, greater financial savings.
- Longer service life: Currently, electrical backup systems last several years and can operate for long periods of time.
- Electricity anywhere: It is possible to have a power supply in remote locations where the electrical grid does not reach.
What types of power plants are there?
There are seven main types of industrial power plants, based on their source of supply:
- Fossil fuel: these meet almost 40% of the world’s energy needs, despite having the highest carbon footprint. They burn coal or hydrocarbons to convert water into steam. With the help of a generator, this steam powers turbines that produce electricity. Gas-fired power plants are less harmful than coal or oil-fired plants.
- Nuclear: uses radioactive elements as its main source. Radioactive fuel undergoes a fission reaction, spreading through a controlled chain reaction and accompanied by an enormous amount of energy in the form of heat. After other processes, electricity is generated.
- Hydroelectric: electricity comes from the gravitational force of flowing water. They often assist nuclear and thermal plants during peak consumption hours and are also useful for irrigation and flood control. They have a lower environmental impact, but are very expensive to install.
- Geothermal energy: its three main types are dry steam, flash steam, and binary cycle. They use steam turbines to produce electricity. They are among the most environmentally friendly power plants.
- Biomass: generates electricity from organic waste, such as olive pomace (agricultural waste from olive trees), sugarcane bagasse, or manure. It is one of the most innovative solutions for reducing solid waste while producing electricity.
- Solar: these use the energy emitted by the sun to generate electricity. Solar panels capture the energy through photovoltaic cells and then convert it into electrical energy. Every day, more countries are interested in solar energy to reduce their dependence on fossil fuels.
- Wind: wind energy is converted into clean electricity by turbines. They require little regular maintenance and are considered relatively cost-effective.
However, at the business and domestic level, there are three types of small power plants that are most commonly used:
- Gasoline power plants: suitable for residential areas and small offices due to their portability, low cost, and ease of use. They can also be used for outdoor events and home emergencies.
- Diesel power plants: these are more robust and powerful plants, ideal for industries and businesses. They are more efficient and have a longer service life than gasoline plants.
- Inverter power plants: these are the most modern and efficient devices, offering clean and stable power, especially for protecting sensitive electronic devices. Recommended for data centers, offices, and homes, they are quiet devices with greater energy efficiency and lower fuel consumption.
Where are power plants used?
Power plants in Barranquilla and other regions of Colombia are used in spaces where continuous electricity is needed, such as schools, hospitals, factories, data centers, and large events. They are also very useful in places where there is no electricity. Some examples of where these plants are used to ensure the continuity of services or activities are:
- Hospitals.
- Homes.
- Computer data centers and server farms.
- Factories.
- Farmland.
- Concerts and similar events.
- Soccer field lighting.
- Construction sites.
- Campsites and caravans.
Power plant maintenance
Due to the wear and tear that power plants suffer when operating as primary or secondary sources of electrical power, they must receive proper preventive maintenance. This depends on the hours of operation, although there are routines for the main systems:
- Lubrication system: checking oil levels, contaminants (water, metals, etc.), inspecting joints and seals for leaks, and checking oil pressure and optimal temperature.
- Intake system: inspecting air intakes and filters, ducts, and clamps.
- Fuel system: check fuel supply, leaks, pump, and fuel lines, and lubricate actuators.
- Cooling system: check antifreeze levels, pressure, leaks, fan, supports, radiator, and operating temperature.
- Exhaust system: check pipes and connections, clamps, fasteners, and muffler.
- Engine electrical system: check drive cables and connections, battery voltage, electrical controls, and protective devices.
- Generator mechanics: check equipment anchoring, mechanical connections, and bearings.
- Generator electrical system: inspect the exciter, cable terminals on the generator, and residual voltage.
- Controls: verification of automatic start-up and remote control.
What is the importance of a UPS?
Power plants play a crucial role in many places and situations. However, there are organizations for which a constant supply of electrical power is vital to their activities:
- Hospitals and operating rooms.
- Blood banks.
- Computer centers.
- Companies that use furnaces.
- Continuous production factories.
In these cases, the minutes it takes for the electric generator to start working can mean the difference between success and total failure. To avoid this critical situation, in addition to using a power plant, UPS are used.
What is a UPS?
A UPS (Uninterruptible Power Supply) is an uninterruptible power system. In other words, it is a device that provides backup electrical power to equipment connected to it when there is a power outage or voltage fluctuation. The transfer time is milliseconds, which can make a significant difference in processes that cannot be stopped at any time. Unlike a regulator, UPSs store energy in batteries that can power equipment for a limited time.
UPS systems and power plants are a successful combination because UPSs provide immediate backup during outages and power plants maintain long-term operation. In addition, this combination can have a positive impact on environmental issues by reducing losses and avoiding equipment restarts, contributing to more efficient use of resources and a lower carbon footprint.
The use of power plants in Colombia is a real investment to ensure that businesses, homes, or industries always have electricity, regardless of power outages due to weather problems or maintenance on the power grid. However, the use of devices that help improve efficiency are also part of the energy solution.
