PLTA (Hydroelectric Power Plant) is a power plant that uses water energy as a source to produce electrical energy. The existence of hydropower can apparently save electricity costs because it utilizes natural resources. In this way, hydroelectric power has the potential to become renewable energy. Hydroelectric power plants are an environmentally friendly, solution for the future of electricity generation.

The Asia-Pacific region can produce 33 percent of hydropower. The existence of dams and reservoirs really helps the hydroelectric power generation process run well. By building reservoirs, it reduces greenhouse gas emissions. The history of hydropower has been used since ancient times to grind wheat and help carry out other tasks. The world’s first hydroelectric power plant was built in England. the generator was built to power arc lamps in art galleries. Electricity generation continued to develop into the 20th century. In Indonesia, around 58 hydroelectric power plants have been built. One of them is in PT Vale at South Sulawesi. Sulawesi is one of the suitable areas for building hydroelectric power plants because it has natural resources that are extensive enough to include water energy. This place has the greatest potential for utilizing natural resources as electrical energy, which can help meet the electricity needs of residents or companies.

Hydroelectric power plants can be an environmentally friendly technology of the future. The initial construction costs are quite expensive, but the subsequent operating costs are relatively cheap. This really helps the population in the economy. Currently there is a prolonged dry season. Apparently in Sulawesi, it has an impact on hydropower because water sources have started to decrease. This means, the residents lack water sources and experience rolling power outages. Even so, the State Power Plant has made efforts, so that the population’s electricity can run well and meet the population’s needs.

PT Vale was formerly known as PT International Nickel Indonesia (INCO) which was founded in 1968. In 1977 PT Vale officially took over the company location in Sorowako, South Sulawesi, and was inaugurated by President Soeharto. PT Vale is one of the largest mining companies in Indonesia. This company is building hydroelectric innovation to replace the use of fossil fuels with renewable energy. The CEO of the company PT Vale has invested fifteen trillion to build three hydroelectric power plants, that help the company’s operations. The presence of hydroelectric power plants reduces operational electricity costs, which have previously taken up quite a lot of company operational costs. Apparently, it is not only conversion to renewable energy, but the benefit of this power plant is that it can manage waste, so that it becomes an environmentally friendly power plant.

Hydroelectric power plants work by utilizing water flows from natural resources which can turn turbines. The turbine will produce mechanical energy which will rotate the generator and produce electricity. During the construction of the hydroelectric power plant, a dam will also be built to accommodate water resources which will also be used for irrigation.

Hydroelectric power has advantages and disadvantages. The advantages is include reducing emission levels, reliable generators, and low operational costs. Why is it said to reduce emissions? Because the potential source is water energy, where water energy is clean and environmentally friendly energy. It becomes a reliable generator because the operating system is not that difficult and depends on natural resources. Having relatively cheap operational costs can help the economy. Apart from having advantages, hydropower also has disadvantages, such as investment costs which are quite expensive and have an impact on climate or weather changes. As is currently happening, Indonesia is experiencing a long dry season so that water availability is starting to decrease.

The President Republic of Indonesia Inaugurates the Hydroelectric Power Plant in South Sulawesi

Mr. President of the Republic of Indonesia stated that Indonesia has considerable potential to build hydroelectric power plants. Indonesia has the potential for 418 Gigawatts of new, renewable electrical energy sourced from water energy. With this, Mr. Jokowi targets that renewable energy will be available at 23 percent by 2025. In the future, he will reduce carbon emissions with hydroelectric power plants. Mr. Jokowi hopes that with hydroelectric power plants, he can achieve renewable energy targets. Mr. Jokowi has inaugurated 2 hydroelectric power plants in South Sulawesi, namely in Poso Regency and Tana Toraja Regency. It was seen on social media that Mr. Jokowi stated that he had inaugurated the two hydropower plants. The two hydroelectric power plants will later become water reserves for Sulawesi Province, namely, South Sulawesi, Central Sulawesi, West Sulawesi and Southeast Sulawesi.
