Commenting on the contract, Kazuki Ishikura, President Director of MHI Group local subsidiary PT. Mitsubishi Power Indonesia, said: "Indonesia has the world's second-largest geothermal potential, and we are honored to have a hand in supporting power plants across Indonesia that leverage this massive potential - from the Darajat geothermal power plants in West Java, Kamojang geothermal power plant in Bandung and now, the Lumut Balai II geothermal power plant. It is our honor to be selected as a trusted partner for Pertamina Geothermal Energy to deliver secure and sustainable power to millions across the nation, and realize Indonesia's renewable energy targets."

Electric power demand in the country began to rise with the resumption of economic activity since the COVID-19 pandemic, and PGE is concentrating its efforts on building new geothermal power plants and increasing output. Mitsubishi Power has supplied a total of six systems for geothermal power plants in Indonesia, with a combined output of around 400 MW. This contract reflects the high regard held for Mitsubishi Power's operational experience, technical capabilities, and EPC coordination ability.
