Lampung inaugurates Gunung Tiga Exploration Project

Lampung Province Regional Secretary Marindo Kurniawan conducted the groundbreaking of PT Pertamina Geothermal Energy Tbk (PGE)'s Gunung Tiga Exploration Project in Gunung Tiga Village, Ulubelu District, Tanggamus Regency, Lampung on June 26, 2025. The activity is part of the inaugural construction and operation of 55 renewable energy power plants in 15 provinces by President Prabowo Subianto.

Marindo stated that the groundbreaking realizes the Lampung Provincial Government's commitment to support the acceleration of national energy development. This project, he added, is expected to bring many benefits that range from improving the regional economy to strengthening collaboration between stakeholders.

Marindo added that the Gunung Tiga exploration project is also an investment for the future of the next generation, with PGE playing a strategic role through the utilization of geothermal energy - a stable, renewable, and sustainable clean energy source.

"With continued technological development and an increasingly precise exploration approach, I believe that this project will make a significant contribution in three main aspects - namely national energy independence, environmentally sustainable development, and, most importantly, improvement of local communities' welfare," he said.

Marindo said that the geothermal exploration project is a crucial initial step to ensure the long-term availability of reliable energy resources.

"We believe that the success of this project will be a lever for the regional economy, create jobs, and strengthen Lampung's position as a province that is proactive in developing green energy," he said.

PGE Operations Director Ahmad Yani stated that the Ulubelu geothermal power plant (GtPP) currently supplies 220 Megawatts (MW) of power, or 20 percent of Lampung's total electricity need of 1200 MW. He also revealed that the Gunung Tiga Project was designed to increase Lampung's power capacity by 55 MW to realize energy independence in the province, which still depends on power supply from South Sumatra Province.

"With 55 MW, we can supply electricity to 450,000 homes with an average usage of around 90 kWh (kilowatt hour) per month, which is a very large [amount]," said Ahmad Yani.

In the initial stage of the project, PGE will drill for exploration wells in three clusters. In addition, a 7 kilometer road will be built with a total investment value of US$36.6 million.
