Jakarta, INTI - PT PLN (Persero) is strengthening its electricity infrastructure to support the continued expansion of Indonesia’s data center sector. Driven by the rapid development of artificial intelligence (AI) and digital transformation, data centers are increasingly becoming an important contributor to national economic growth.
PLN President Director Darmawan Prasodjo said the expansion of data centers requires increasingly specialized electricity support, particularly in terms of capacity, reliability, power quality, and access to clean energy. This is prompting PLN to develop infrastructure and services that are aligned with customers’ requirements and expansion plans.
“The rising demand for electricity across the data center ecosystem highlights the growing importance of energy infrastructure to the digital economy. PLN wants the development of power infrastructure to keep pace with the digital sector, with planning carried out early so that energy requirements can be anticipated and investment can grow sustainably,” Darmawan said.
PLN Serves 159 Data Center Customers with 2,038 MVA Capacity
During a discussion at Electricity Connect 2026 at ICE BSD City, Tangerang, on Wednesday, September 23, 2026, PLN Executive Vice President of Enterprise Sales and Customer Service Dini Sulistyawati said PLN currently serves 159 data center customers with a total connected capacity of 2,038 megavolt-amperes (MVA).
Around 99% of this capacity remains concentrated in the Java-Madura-Bali electricity system, with West Java emerging as one of Indonesia’s largest data center clusters.
However, data center development is increasingly expanding beyond these areas, including into Sumatra, Kalimantan, and Sulawesi. As this expansion continues, electricity demand from the technology sector is expected to rise, requiring power infrastructure planning that takes into account the specific characteristics and requirements of each region.
The data center customers currently served by PLN have recorded total electricity consumption of 2,378 gigawatt-hours (GWh).
“We believe this is only the beginning. Artificial intelligence, cloud computing, digital services, and Indonesia’s growing digital economy will continue to create significant new electricity demand,” Dini said.
Early Infrastructure Planning Key to Meeting Data Center Power Demand
She added that PLN’s biggest challenge is balancing the acceleration of power supply capacity with reliability, affordability, and long-term system stability.
The development of power generation and transmission networks needs to be planned in an integrated manner and initiated early to anticipate future data center demand. To support this approach, PLN is encouraging early alignment and coordination from the initial stages of data center development.
“Earlier commitments and closer coordination between both sides, supported by clearer demand projections, realistic energization schedules, appropriate capacity development timelines, and stronger cooperation among PLN, customers, and the government, are essential. Therefore, managing data center commitments should become a joint planning process,” Dini concluded.
Conclusion
PLN’s efforts to strengthen electricity infrastructure reflect the growing energy demands of Indonesia’s expanding data center industry. With AI, cloud computing, and digital services driving new demand, early infrastructure planning and closer coordination between PLN, data center operators, and the government will be essential to ensuring reliable and sustainable power supply.
