Ayala-led ACEN Corp. said it is pursuing net-zero greenhouse gas (GHG) emissions within the next 25 years, as it now operates on a 100-percent renewable energy (RE) portfolio following its ongoing exit from conventional power plants.

In a disclosure to the Philippine Stock Exchange (PSE) on Monday, Dec. 29, ACEN said it achieved 100-percent RE generation across its portfolio this year, the majority of which are solar projects.

The company revealed that in 2025, it reached 4,634 megawatts (MW) of solar, 1,957 MW of wind, 115 MW of geothermal, and 304 MW of battery energy storage systems (BESS).

Eric Francia, president of ACEN, shared, “This milestone reflects our long-term strategy to align ACEN with the future of the energy system, while supporting decarbonization in a commercially disciplined way.”

Since 2016, ACEN has grown its RE platform to more than seven gigawatts (GW), which are either operating, under construction, or with committed capacity. Because of this, the Ayala-led firm is said to be the fastest-growing RE company in Asia-Pacific.

It has also expanded its presence outside the Philippines, such as in Australia, where it completed the 520-MW-direct-current (MWdc) Stubbo solar project this year. ACEN has also grown its footprint in Vietnam, India, Laos, and Indonesia, among others.

Nearly a decade ago, the company pushed for its first 1,000 MW of capacity, most of which came from its coal-fired power assets. At the time, renewables accounted for only two percent, as these technologies were still in their early stages.

In September, the company divested from its diesel plants: the 52-MW diesel plant in Bulacan, 116-MW plant at Subic Bay Freeport Zone, and 21-MW facility in La Union.

“As the company looks ahead, its focus extends beyond capacity expansion toward enabling a just, orderly, and inclusive energy transition that delivers long-term value for stakeholders,” ACEN concluded.
