Jakarta – The government continues to strengthen efforts to maintain the stability of the national electricity supply by strengthening coordination and integrated primary energy planning. This step is being taken to ensure that the electricity needs of the public and the industrial sector remain reliably met amidst growing energy demand and the transition to cleaner energy.
PT PLN Energi Primer Indonesia (EPI) projects that primary energy demand for power generation will grow by an average of around five percent per year until 2035. In this projection, coal will remain the primary component in the primary energy mix for power generation, while natural gas will play a crucial role as a transitional energy source to maintain electricity system flexibility as the use of new and renewable energy (NRE) increases.
Head of the Corporate Planning Unit of PLN EPI Primary Energy Management, Anggoro Wisaksono, emphasized that strengthening primary energy supply is one of the main focuses for maintaining the reliability of the national electricity system.
“One way is through the development of national gas infrastructure within Indonesia’s electricity system,” Anggoro said while speaking at the Hipmi Power Development Forum 2026 in Jakarta.
According to him, planning for the electricity sector must be carried out comprehensively, starting from projecting electricity needs, building power plants, transmission, distribution, to the availability of primary energy as the main fuel for power plants.
“PLN EPI operates in the primary energy sector. We ensure a sustainable and reliable fuel supply to power plants,” he said.
The government views primary energy as a strategic factor in maintaining national energy security. During the energy transition period, coal and gas will continue to play a key role in supporting the reliability of the national electricity system.
“Coal and gas continue to play a role in maintaining system reliability during the transition period, particularly to ensure system stability,” Anggoro emphasized.
In addition to strengthening coal and gas supplies, PLN EPI also encourages the use of biomass through a co-firing program at PLTU.
“Besides coal and gas, there will also be biomass. This is also an opportunity for young entrepreneurs,” he said.
In the infrastructure sector, PLN EPI is preparing various strategic national gas development projects spanning from Sumatra to Papua, including the construction of FSRUs, LNG carriers, ORUs, and gasification facilities. According to Anggoro, this step is crucial given Indonesia’s numerous isolated electricity systems.
“We are an archipelagic nation, with many isolated systems on both small and large islands. This presents a unique challenge,” he said.
Despite evolving global geopolitical dynamics, PLN EPI ensures a secure primary energy supply. To ensure a sustainable gas supply, the company combines domestic production and international partnerships.
“We can’t work alone. Collaboration with global partners is essential,” Anggoro concluded.
