Electricity has become the backbone of modern technological progress. As population growth surges, so does the demand for energy supply. However, the availability of conventional resources like coal and oil continues to dwindle, pushing Indonesia to seek sustainable energy alternatives. Amid these challenges, wind energy has emerged as a promising solution.
PLTB Sidrap, Indonesia’s first and largest wind power plant (known locally as Pembangkit Listrik Tenaga Bayu), stands as a tangible testament to the nation’s efforts to harness natural potential in addressing the energy crisis. Towering over the Pabbaressang Mountains in South Sulawesi, this project is not merely a technological milestone but a strategic leap toward clean energy independence.
Private Collaboration and National Targets
The concept of PLTB Sidrap was outlined in the Electricity Supply Business Plan (RUPTL) of state-owned utility PLN for 2016–2025, aligning with the government’s goal to boost national power capacity to 35,000 MegaWatts by 2019. Two local companies, PT UPC Renewables Indonesia and PT Binatek Energi, collaborated to realize this project.
According to the Directorate General of New Renewable Energy and Energy Conservation, the construction of PLTB Sidrap required an investment of US$150 million (equivalent to IDR 2 trillion). This substantial investment reflects Indonesia’s commitment to reducing reliance on fossil fuels while driving its renewable energy mix to 23% by 2025.
The location was chosen after intensive studies. Citing the DJKN Indonesia website, wind speeds in Sidrap average 6.43 meters per second—higher than other regions like Oelbuluk in East Nusa Tenggara (6.1 m/s).
As analyzed in JETri: Jurnal Ilmiah Teknik Elektro published in 2019, these conditions made the Pabbaressang Mountains ideal for installing 30 colossal turbines. Construction began in August 2015 and concluded within 2.5 years, marking a new chapter for Indonesia’s green energy industry.
Cutting-Edge Technology and Broad Reach
PLTB Sidrap commenced operations in 2018. Thirty wind turbines manufactured by Gamesa Lolica Corporation soar 80 meters high, equipped with 57-meter blades that rotate gracefully across a 100-hectare site.
According to DJKN Indonesia website, each turbine generates 2.5 MegaWatts, feeding a total of 75 MegaWatts into Sulawesi’s power grid. This output can supply electricity to 150,000 households with 450 VA capacity, reaching South, West, and Central Sulawesi.
Operated by PT UPC Sidrap Bayu Energi, PLTB Sidrap has become a backbone of power supply in eastern Indonesia. Its presence in the villages of Mattirotasi and Lainungan has transformed Watang Pulu from a remote area into a national hub for energy innovation.
Benefits Across Multiple Fronts
PLTB Sidrap’s primary advantage lies in its resource: wind. This infinite energy source produces zero carbon emissions, aligning with global efforts to combat climate change.
Citing Barito Renewables, the project also delivers economic benefits. During construction, thousands of local workers were employed, while nearby MSMEs (Micro, Small, and Medium Enterprises) gained new business opportunities.
Beyond functionality, the majestic wind turbines offer breathtaking scenery. PLTB Sidrap has become an alternative tourist destination, attracting photographers and travelers eager to witness the harmony of technology and nature.

PLTB Sidrap’s success proves Indonesia’s capability to transition from conventional to renewable energy. This project not only addresses today’s electricity needs but also lays the foundation for future generations. With consistent policies and investments, Indonesia can contribute meaningfully to global clean energy production.
