The start-up of the new 28.9 MWe binary geothermal power plant was a success, located at Bacon-Manito on the island of Luzon, and operated by Turboden, part of the Mitsubishi Heavy Industries(MHI) group. Experienced in organic Rankine cycle(ORC) technology in the Palayan Bayan expansion project of the Energy Development Corporation(EDC).
Turboden’s binary geothermal power plant
The binary power plant expands the capacity of the geothermal plant existing Bacon-Manito geothermal Bacon-Manito, which produces 140 MW, and was successfully synchronized with the Luzon grid last January. BacMan Geothermal, a subsidiary of EDC, is responsible for the operation of this plant, which is expected to generate 253,000 MWh gross and 219,800 MWh net annually, thereby reducing carbon emissions in the Philippines by approximately 72,200 tons per year. This is equivalent to the CO₂ absorption capacity of a forested area, 4.7 times the size of Manila.
Construction of the Palayan binary plant began in mid-2021. Turboden delivered an ORC power plant that harnesses waste heat from the 120 MW Palayan Bayan 1 flash geothermal power plant, generating electricity without the need for additional steam.
For example, the Philippines, being a volcanic archipelago and the world’s third largest producer of geothermal energy, is committed to using renewable energy to meet the growing demand for electricity driven by its economic growth. With an installed capacity development rate that is the highest in relation to available resources worldwide, the Philippines is a reference in geothermal energy development.
“The new binary geothermal power unit increases the power output of the existing flash plant at BacMan. ORC technology is extremely efficient in these projects, as it requires no additional drilling and can utilize all of the waste heat from the brine. This solution is highly replicable in many high-enthalpy geothermal plants both in the Philippines and around the world.”

In addition to its environmental benefits, the project has received international recognition. The Ministry of Environment of Japan selected it as one of the“Bilateral Credit Mechanism(BCM)Financial Support Projects ” for fiscal year 2020. This recognition elevates the project’s contribution to CO₂ reduction in the Philippines, and supports Japan’s goals to decrease its carbon footprint.
