Ecobiz.asia – Indonesia’s state-owned electricity company PT PLN (Persero) plans to launch Time-based Renewable Energy Certificates (T-REC) in 2028, allowing customers to track renewable electricity use in greater detail, including how closely their hourly consumption matches renewable energy generation.
Bobby Cristya Surya, PLN’s Vice President for Commercial Product Planning and Strategy, said T-REC would build on the company’s existing Renewable Energy Certificate (REC) service, which customers use to document renewable electricity consumption, including in corporate sustainability reports.
Under T-REC, customers will be able to identify the power plants supplying their electricity and assess the hourly alignment between their electricity consumption and renewable energy generation.
“Previously, REC could simply be selected for monthly reporting on renewable energy use. Now, some customers want to monitor their renewable electricity consumption in real time, identify which power plant supplies it, and analyze the matching down to the hourly level,” Bobby said during a panel discussion at the Indonesia International Sustainability Forum 2026 in Jakarta on Tuesday (Oct. 6, 2026).
T-REC remains in the pilot stage and will be developed with several partners before its commercial launch, Bobby said. The service will also display a matching rate, indicating how closely a customer’s electricity consumption aligns with renewable energy supply. In an example presented during the discussion, the matching rate could reach 90%.
Growing Demand
Bobby said the planned service responds to changing corporate demand for renewable electricity. Companies increasingly need to demonstrate renewable energy use not only for sustainability reporting but also to meet business requirements, particularly when operating in global markets.
These requirements are extending across supply chains, with companies increasingly encouraging their suppliers to adopt similar renewable energy standards.
Data centers are another source of growing demand for green electricity. Bobby said around seven to eight data centers were expected to enter Indonesia, prompting PLN to prepare electricity supplies and services that meet customers’ needs while maintaining reliability and affordability.
At the regional level, ASEAN energy consumption is projected to increase by around 54% by 2050, Bobby said. He also cited approximately 143 companies that aim to source at least 60% of their energy from renewable sources by 2030, with a target of reaching 100% by 2060 at the latest.
To meet these needs, PLN is developing a range of renewable energy services covering power generation, certification, digital platforms and energy management.
Customers can also use PLN’s dedicated-source service to select their electricity supplier and access online information about supply availability and capacity adequacy.
T-REC is part of PLN’s broader effort to expand green electricity services and support Indonesia’s net-zero emissions target for 2060. Other initiatives include batteries, energy storage systems, grid interconnections and new energy technologies. ***
