Razon-led Manila Water Co. expanded its commitment to renewable energy through a supply agreement with the unit of Aboitiz Power Corp. to power its operations in the country.
In a statement, the water concessionaire for Metro Manila’s east zone said Wednesday it partnered with AdventEnergy Inc. to integrate a 20 percent renewable energy mix into its power consumption.

The deal covers Manila Water’s primary service area and several provincial subsidiaries, including units in Cebu, Tagum, Calbayog, Laguna, Boracay, and South Luzon

Roberto R. Locsin, the newly appointed Manila Water president and chief executive officer, said the partnership would enable the company to deliver sustainable water solutions.

“We take pride in formalizing this partnership. It truly makes a difference in the lives of our customers knowing that a water utility can work with a partner like AdventEnergy to deliver sustainable solutions that we have worked so hard to pursue,” he said.

AdventEnergy President James Yu, meanwhile, said the agreement builds on a preliminary cooperation established in 2023.

Yu noted that the partnership aligns with the power firm’s goal of providing reliable energy to critical infrastructure providers, supporting Manila Water’s mandate to maintain water security in urban and rural hubs.

The transition to a cleaner energy mix follows Manila Water’s early adoption of the Energy Regulatory Commission’s retail aggregation program.

In February 2025, the company became a pioneer in the program by consolidating the electricity requirements of 10 wastewater facilities. That consolidation resulted in a combined average demand of 500 kilowatts, allowing the company to bypass traditional distribution utilities and source power directly from the contestable market.

Under the commission’s guidelines, the aggregation program enables large-scale end-users to group multiple facilities to meet the threshold for the retail competition and open access regime. This flexibility allows companies like Manila Water to negotiate more competitive rates and specify the source of their electricity, such as geothermal, solar, or wind power.

Manila Water continues to scale its provincial footprint through its non-east zone businesses, which include Estate Water and LARC Water, as it seeks to hedge against rising traditional fuel costs.
