PT PLN (Persero) has recorded a new history because it has successfully operated the largest floating solar power plant in Indonesia with a peak capacity of 561 kilowatts (kWp). The operation of the floating PLTS in the Tambak Lorok area, Semarang will increase the new renewable energy mix in Indonesia.


The Floating PLTS, which is operated through PLN’s subsidiary, PLN Indonesia Power (PLN IP), is part of the construction of PLTS with a total of 920 kWp in several buildings of the PLN IP Semarang Power Generation Unit (PGU) Gas and Steam Power Generation Complex (PLTGU).

Main Director of PT PLN (Persero) Darmawan Prasodjo said the construction of this PLTS is a form of PLN’s commitment to its subsidiaries in an effort to encourage the energy transition program, reduce the impact of climate change and achieve Net Zero Emissions (NZE) 2060.


“In an effort towards NZE 2060 PLN has carried out several initiatives. For example, by no longer making new contracts for the construction of coal-fired power plants. Instead, PLN has started building New Renewable Energy (EBT)-based power plants. The big strategy is shifting away from fossil-based generators to EBT generators,” said Darmawan.

In line with Darmawan, the Main Director of PLN Indonesia Power, Edwin Nugraha Putra, said that the construction of this PLTS is a commitment by PLN IP and its subsidiary, PT Indo Energi Hijau, in realizing the energy transition in Indonesia. PLTS development is also part of efforts to optimize potential land which is integrated with renewable energy generation.

“This Floating PLTS was built on a 1-hectare water pond with a construction time of 8 months. In the first year this PLTS will produce environmentally friendly electricity of 1.4 million kWh per year and contribute to reducing CO2 gas emissions by up to 1,304 tons/year,” said Edwin.

Edwin continued, PLN has energy transition initiative programs that consolidate the support of various parties. Both business entities and funding institutions are supported by the government to achieve NZE 2060.

“This is a form of innovation that we are doing to support the supply of clean energy in Indonesia and achieve net zero emissions by 2060,” concluded Edwin.
