Darmawan Prasodjo, President Director of PLN, said in his statement on Jan 2 that REC is the answer to the need for decarbonized steps, especially in the industrial and business sectors.
REC is a form of PLN services to make it easier for customers to obtain recognition for the use of renewable energy that is transparent, accountable, and internationally recognized.
Each REC certificate proves that the electricity per MWh utilized by customers comes from renewable or non-fossil generators.
"PLN, as the sector leader in accelerating the use of new renewable energy, will support the competitiveness of the national industry by encouraging the use of clean energy as the basis for electricity. We are presenting procurement options to fulfill the target of 100%use of renewable energy," Prasdojo said.
Some 296 customers have used PLN’s REC until the end of 2023. Industry and business sectors in West Java, Banten, East Java, and Jakarta make the most use of REC.
PLN’s REC uses an electronic tracking system from APX TIGRs to make sure that once the certificate is issued, it cannot be bought or sold to other parties. The entire process has also been verified to meet international standards.
Four PLN plants are currently prepared to supply green electricity to customers: the Kamojang Geothermal Power Plant for Java, Madura, and Bali electricity systems; the Lahendong Geothermal Power Plant and Bakaru Hydroelectric Power Plant for Sulawesi electricity system; and the Ulubelu Geothermal Power Plant for Sumatra electricity system.
