Eton Properties Philippines has completed a portfolio-wide transition to 100% renewable geothermal energy across 14 developments, marking a major operational milestone for the Lucio Tan Group’s property arm as it expands its sustainability efforts across residential, commercial, office, and mixed-use assets.

The transition was formally marked through a handover ceremony with First Gen Corporation, which supplies the geothermal power used by the participating developments. Eton said the move represents one of its most comprehensive sustainability initiatives to date.

In total, the 14 developments now source more than 11 megawatts (MW) of electricity from renewable geothermal energy.

The shift began with six Eton developments that moved from traditional fossil fuel suppliers to renewable power under the Retail Competition and Open Access (RCOA) framework. These facilities account for 8.7 MW of contracted demand and are powered by the Tongonan Geothermal Power Plant.

This year, the company expanded the initiative by bringing eight additional developments into the program through the Green Energy Option Program (GEOP). The expansion added 2.45 MW of contracted demand supplied by the Unified Leyte Geothermal Power Plant and extended renewable energy use to Eton’s residential and mixed-use properties.

According to Eton Properties, the transition is expected to provide greater price stability and supply security across its portfolio while helping shield tenants and homeowners from fluctuations in energy costs.

“Our shift to 100% renewable energy across all our properties in Metro Manila reflects both our belief in sustainability and more importantly our commitment to helping restore a greener earth. We are even more grateful that this important initiative will also allow us sustainable savings, especially amid the oil and energy crisis,” said Eton Properties Chief Finance Officer Che Mutuc.

Mutuc added that the initiative is intended to benefit both the company and the communities within its developments.

“This will not only help our bottom line but also that of our tenants and homeowners as we flow the savings with them,” she said.

The renewable energy transition forms part of Eton Properties’ broader sustainability strategy under its Beyond Green platform and ETON Sustainability Framework, which guides the company’s environmental, governance, and community-focused initiatives.

For First Gen, the partnership highlights the growing role of geothermal energy among large commercial power users seeking cleaner and more reliable electricity sources.

“In a country where most developments are still fueled by coal, choosing renewable energy is a rare and premium distinction. It is a badge of operational exclusivity. By choosing our geothermal power, Eton is utilizing the steady heartbeat of the clean grid, renewable energy that runs 24 hours a day, 7 days a week,” said Marjorie Castelo, Lead Customer Progress Partner at First Gen.
