EDC to Triple Leyte Geothermal Capacity by 2030

Tacloban City — The Energy Development Corporation (EDC) is planning a major expansion of its geothermal operations in Leyte that could increase the province’s power generation capacity from 120 megawatts (MW) to as much as 300 MW by 2030 to 2031.

The company shared its expansion plans during the First Gen Renewables Media Academy held on July 22, 2026, in Tacloban City, where EDC officials discussed ongoing projects and future developments in Leyte’s geothermal sector.

A key part of the expansion is the modernization of the Upper Mahiao geothermal power plant, which is expected to raise its capacity to between 200 MW and 300 MW. EDC also plans to develop more facilities and conduct additional drilling activities that could further increase geothermal output in the coming years.

Estanislao “Jun” Pialago, EDC’s Head of Facility Operations and Leyte Site, said several projects are already underway as the company works toward its long-term goal. These include the 28 MW Mahanagdong Binary expansion and the installation of the province’s first 10 MWh battery energy storage system, which are expected to improve the reliability of geothermal power supply.

Jennifer Wenceslao, EDC’s Head of Corporate Relations for Leyte, said the expansion is also aimed at addressing concerns from communities regarding electricity supply.

“There is an ongoing expansion now in Mahanagdong… that’s another 28 MW that will supply all over the Philippines,” Wenceslao said.

She added that the additional capacity will help provide more reliable power as demand continues to grow.

Alongside the expansion, EDC said it will continue its environmental protection efforts, particularly its reforestation program. Under the company’s 100-to-1 tree replacement policy, 100 trees are planted for every tree removed for development activities.

Ted Troyo, head of the Leyte geothermal site, said protecting the environment is important because geothermal operations depend on healthy forest areas and watersheds.

“We have to balance [the projects] so the environment is not destroyed,” Troyo said.

EDC said the planned expansion will allow Leyte to provide more renewable energy while continuing efforts to protect the natural resources that support the province’s geothermal operations.
