Rarely Discussed! Let's Understand How Electricity From Hydropower Can Get To Homes

YOGYAKARTA - Hydroelectric Power Plants or hydropower plants are one of the most widely used renewable energy sources in Indonesia. The hydropower plant utilizes the flow of water from dams or rivers to generate electricity. However, many people wonder, how can electricity from the hydropower plant reach home? The process actually involves several stages ranging from generation, transmission, to distribution to consumers. This article will discuss in full how electricity from hydropower reaches homes.

Stage 1: Power Plantation In PLTA

The process starts from a dam or flow of water flowing into a turbine. The flowing water has high kinetic energy and is used to rotate the turbine. This turbine is connected to a generator, which converts mechanical energy into electrical energy. The electricity produced by the hydropower plant is usually in the form of alternating current electricity (AC) with medium or high voltage to make it easier to transmit long distances.

Stage 2: Electric Voltage Transformation

The newly generated electricity has relatively low voltage. In order to be sent to houses far from the hydropower plant, electricity must be increased first. This process is carried out in step-up transformers, which increase electricity voltage so that electricity can travel long distances with minimal energy loss.

Phase 3: Electrical transmission

After the voltage is increased, electricity is channeled through the transmission network. This network is usually a high-voltage cable that connects hydropower with substations in various regions. Electric transmission uses high voltage because smaller currents cause less energy loss during long-distance travel.

Stage 4: Electricity Distribution

After arriving at the main substation, electricity from the hydropower plant will go through a voltage reduction process using a step-down transformer. This transformer lowers electricity voltage to be safe and in accordance with household needs. After that, electricity is channeled through a distribution network to homes, schools, offices, and public facilities.

Phase 5: Installation Of Electricity Meters At Home

At home, electricity enters through local distribution cables and passes through the electric meter. This meter serves to record household electricity consumption so that electricity bills can be calculated accurately. From the meter, electricity is channeled to the home panel which then distributes electricity to various devices and lights at home.

Security and Control Of Electricity From Hydropower Plants

The hydropower plant is equipped with a control system to maintain the stability of electricity supply. This system monitors voltages, currents, and electrical frequencies to remain stable during transmission and distribution. In addition, the distribution network is equipped with circuit breaks and safety switches to prevent excess electricity from damaging household appliances.

Benefits Of Electricity From Hydropower

Using electricity from hydropower has many advantages:

The question of how electricity from hydropower can reach home can be answered through five main stages: power generation at hydropower, electric voltage transformation, long-distance electricity transmission, electricity distribution to local networks, and installation at home through meter and electrical panels. This process ensures that electricity generated from hydropower can be used safely and efficiently by the community. By understanding this process, we can better appreciate technology and systems that make electricity from hydropower to home safely.
