Background
Sulut-1 power station consists of 2 x 50 MW units.[4] The plant will be built in Bindjeta, East Bolangitang District, North Sulawesi.[5]
The long-range plan for 2019-2028 lists the two units coming online in 2021 and 2022.[6] In September 2019 Persero signed contracts for construction of the plant.[7] PT Medco Power Indonesia was awarded the operation and maintenance (O&M) contract. A consortium consisting of Medco Power, PT Inti Karya Persada Tehnik, PT PP Persero Tbk, ITOCHU Corporation, and Sumitomo Heavy Industries, was awarded the engineering, procurement, and construction contract.[8] The EPC contract was worth IDR1.24 trillion (approximately US$88 million).[9]
A June 2021 report from the Institute for Energy Economics and Financial Analysis lists a target operation date of 2023/2024 for the Sulut-1 power station.[10] An August 2021 news report, however, stated that progress on the Sulut-1 power station was 22% complete, and that commercial operation was targeted for Q4 2022.[9] As of December 2021 the estimated completion date for Unit 1 was 2023, and for Unit 2 it was 2024.[11]
In June 2022, the target operation for both units was described as "before 2024".[12]
In August 2023, construction was reportedly 85% complete.[13]
In September 2023, the units were undergoing testing. A PLN representative stated that the power station had been developed with a system that could co-fire with another fuel besides coal in the future.[14] At the end of September 2023, construction was reportedly 90% complete, and both units were slated to be commissioned in 2024.[15]
In February 2024, an accident occurred at the construction site, resulting in two injuries. A protest was held to temporarily halt work at the power station, as demonstrators reportedly suspected that the workers involved in the incident were not wearing protective equipment.[16]
As of December 2024, Sulut-1 power station did not appear to have entered operation.
In March 2025, Sulut-1 power station reportedly passed its load rejection test.[17]
In June 2025, Indonesia publicly released its updated electricity supply business plan (RUPTL 2025-2034). The commercial operation of Sulut-1 power station in 2025 was listed as a priority.[18]
Unit 1 began operating in March 2025, and Unit 2 began operating in July 2025.[19][20]
In November 2025, the Corruption Eradication Commission reportedly detained officials related to several development projects, including Sulut-1 power station.[21]
