Jakarta, INTI - Vice President Director of Bank Mandiri, Henry Panjaitan, visited the Muara Tawar Power Generation Unit (UP), operated by PT PLN Nusantara Power (PLN NP), on Friday, April 10, 2026, alongside PLN NP’s Director of Finance and Risk Management, Teguh Widhi Harsono, and senior management from both organizations. The visit aimed to observe firsthand the role of Muara Tawar in maintaining power system reliability, particularly during peak demand periods and fluctuations in renewable energy supply.
In the context of the energy transition, power plants such as the Muara Tawar Combined Cycle Gas and Steam Power Plant (PLTGU) play a critical role in ensuring grid stability. This is essential to support the integration of renewable energy with adequate infrastructure.
“Increasing the share of renewable energy requires infrastructure that can maintain system reliability. The Muara Tawar plant plays a key role due to its ability to respond quickly to load changes and supply fluctuations,” Henry stated.
Beyond ensuring operational reliability and improving energy efficiency, which contributes to emissions reduction, the visit also reflects Bank Mandiri’s commitment to reducing emissions as part of its goal to achieve Net Zero Emissions for operational Scope 1 and 2 by 2030. One of the approaches includes carbon offset initiatives, such as purchasing verified carbon units. This strategy is considered a feasible way to support these targets while aligning with the development of carbon market regulations in Indonesia.
Carbon Market Participation and Decarbonization Strategy
In January 2025, during the launch of Indonesia’s International Carbon Exchange (IDXCarbon), Bank Mandiri purchased 5,000 tCO₂e of carbon units from PLN NP’s project at Muara Tawar. The project involves converting a single-cycle power plant into a combined-cycle system, improving efficiency by capturing waste heat and converting it into additional electricity. These carbon units have been validated and verified by an independent third party.
This purchase demonstrates that Bank Mandiri is not only supporting the energy transition through financing but is also actively participating in the carbon market ecosystem in Indonesia. It further contributes to the development of the voluntary carbon market, which is becoming increasingly relevant.
The acquisition of carbon units from PLN NP also reflects Bank Mandiri’s support for emission reduction projects undertaken by its key clients. PLN NP, part of the PLN Group, is a major corporate banking client of Bank Mandiri. As such, the bank’s support extends beyond financing to active involvement in its clients’ decarbonization initiatives.
“Bank Mandiri supports the energy transition not only through financing but also through active participation in Indonesia’s growing carbon ecosystem. We see this as part of a gradual and measurable effort to support national decarbonization targets,” Henry concluded.
Conclusion
Bank Mandiri’s visit to the Muara Tawar power plant highlights the growing role of financial institutions in supporting the energy transition beyond traditional financing. By contributing to system reliability and actively participating in the carbon market, the bank demonstrates a more holistic approach to decarbonization. This integrated effort not only supports national energy goals but also accelerates the development of a more sustainable and resilient energy ecosystem in Indonesia.
