PT PLN (Persero) is strengthening its electricity infrastructure to support the growth of data centers in Indonesia. The increasing demand is in line with the development of artificial intelligence (AI), cloud computing, and digital transformation.
PLN President Director Darmawan Prasodjo said the growth of data centers requires electricity support with increasingly specific characteristics, ranging from capacity, reliability, and power quality to the utilization of clean energy.
This situation has prompted PLN to prepare infrastructure and services tailored to customers’ needs and development plans.
“The growing demand for electricity within the data center ecosystem demonstrates the increasing importance of energy infrastructure to the growth of the digital economy. PLN wants the development of electricity infrastructure to progress in line with the growth of the digital sector, with planning carried out at an early stage so that energy needs can be anticipated and investment can develop sustainably,” Darmawan said in a written statement on Saturday, September 26, 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).
Approximately 99 percent of this capacity remains concentrated in the Java-Madura-Bali electricity system, with West Java being one of the largest data center clusters.
However, data center development is beginning to expand beyond these areas, including to Sumatra, Kalimantan, and Sulawesi. This expansion is also driving increased electricity supply requirements in the technology sector. Currently, the 159 data center customers record total energy 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 new electricity demand on a very significant scale,” Dini said.
Infrastructure Planning
Furthermore, Dini said PLN’s challenge is to maintain a balance between accelerating supply capacity and ensuring reliability, affordability, and long-term system stability.
According to her, power generation and grid development need to be planned in an integrated manner from the outset to anticipate the growth in data center demand. PLN is also promoting an early alignment approach, involving coordination from the initial stages of data center development. This is intended to ensure that electricity requirements, capacity development schedules, and infrastructure readiness can be planned in a more measurable manner.
“Earlier commitments and closer coordination between both parties, supported by clearer demand projections, realistic energization schedules, an appropriate pace of capacity development, and stronger cooperation among PLN, customers, and the government are essential. Therefore, managing data center commitments must become a joint planning process,” she concluded.
