BANDA ACEH | INDATANEWS.COM – The Deputy Chair of Commission III of the Banda Aceh Regional House of Representatives (DPRK), Tuanku Muhammad, has called on Indonesia's central government and state-owned electricity company PT PLN to accelerate the development of an independent power system in Aceh. The move aims to reduce the region's reliance on the North Sumatra interconnection grid (Sumbagut) and strengthen local energy security.
Tuanku Muhammad stressed that a stable electricity supply is essential for sustained economic development. However, Aceh's full dependence on the Sumbagut system leaves the region vulnerable to disruptions originating outside its territory.
"Energy security is the foundation of economic development. Aceh must not remain in a fragile position due to its dependence on the Sumbagut system. We need a stronger and more independent power network to ensure reliable electricity for the public. The recent power outages over the past two days have caused significant losses and left a deep impact on the community," he said.
Risks of the Sumbagut Interconnected Grid
He explained that Aceh remains heavily integrated into the North Sumatra electricity network, which also serves other provinces. As a result, disruptions in one area can quickly affect supply stability in Aceh.
According to PT PLN data, electricity demand in Aceh continues to rise annually. At the end of 2024, peak load reached around 516 megawatts (MW), while available capacity stood at approximately 733 MW. In 2023, available capacity was about 822 MW, with peak demand reaching around 567 MW.
Despite what appears to be a power surplus, Tuanku Muhammad said the system remains vulnerable.
"A surplus in capacity does not guarantee energy security if control is still dependent on external networks. In 2022, we saw how a disruption in LNG regasification within the Sumbagut system triggered widespread outages affecting hundreds of thousands of customers," he noted.
PLTG Ladong and Strengthening Local Energy Sources
Tuanku Muhammad urged the government to prioritize the strengthening of local power plants so Aceh can respond more effectively during crises. A key focus is the revitalization and optimization of the
PLTG Ladong gas power plant in Aceh Besar.
"PLTG Ladong must be prioritized for revitalization. Aceh has the gas resources and infrastructure needed for optimal operation. It could become a key pillar of energy security," he said.
He also highlighted other local energy facilities, including the PLTU Nagan Raya coal-fired power plant, the Arun gas and steam power plant (PLTMG), as well as smaller diesel and hydropower stations.
He added that Aceh also holds significant potential for hydropower, geothermal energy, and natural gas development.
Rising Demand and Future ChallengesWith continued economic expansion, industrial growth, the development of health and education infrastructure, and new investment inflows, electricity demand is expected to increase further, he warned.
"If Aceh continues to rely entirely on external systems, we will face ongoing uncertainty—not only in terms of blackouts but also economic losses and declining investor confidence," he said.
He concluded by urging the central government and regional stakeholders to develop a clear roadmap for energy security, prioritizing local power generation and sustainable electricity supply.
"Aceh should finally have an independent electricity system—for its economic future, investment climate, and the welfare of its people," he added.
