Indonesian industries shift toward green energy and solar integration

The Indonesian industrial sector is increasingly adopting rooftop solar photovoltaic (PLTS) systems to enhance operational efficiency and meet global green branding standards. Integrating solar power allows factories to synchronize peak production hours with peak sunlight intensity, reducing reliance on the public grid and lowering electricity costs.

In Purwakarta, West Java, PT PLN (Persero) is facilitating an energy transition for PT Indorama Synthetics Tbk and PT Indorama Polychem Indonesia Tbk. PLN is constructing a 150 kV high-voltage substation and transmission lines, which are expected to be operational by early 2027. Once this infrastructure is complete, the companies will transition from their captive coal-fired power plants—totaling 62 MW in capacity—to PLN’s electricity system, supporting industrial decarbonization efforts.
