Solar installations support core operations
The newly installed capacity uses a grid-tied solar system, with all power generated dedicated exclusively for Manila Water’s own operational use, subject to securing the required permits, licenses, and regulatory clearances.
This approach supports the utility’s strategy of integrating renewable energy directly into its core infrastructure while maintaining compliance with regulatory standards.
Covering critical water infrastructure
The decentralized solar installations span critical pumping stations and treatment plants, including Kingsville, Siruna, East La Mesa, Makati, and Lucban pumping stations, as well as Calawis, East Bay, Taguig North, Marikina North, and Ilugin treatment facilities.
By embedding solar solutions across these sites, Manila Water aims to improve operational efficiency while addressing rising electricity costs, particularly transmission and ancillary charges.
The additional solar capacity is expected to significantly reduce the company’s carbon footprint while providing a strategic hedge against volatile power prices.
Setting a regional benchmark
Manila Water president and CEO Jocot de Dios said the partnership with MSpectrum positions the company as a potential regional model for sustainability in the water sector.
“This partnership can be a showcase not just in the Philippines but in the region as well. I want Manila Water to be a beacon in the Asia Pacific for renewable energy in a water utility company,” de Dios said.
A long-term commitment to renewable energy
MSpectrum chief operating officer Patrick Panlilio highlighted the complexity of implementing renewable energy solutions at scale and reaffirmed the company’s commitment to supporting Manila Water’s goals.
“Being renewable is not easy. It requires commitment, investment, execution excellence, and continuous monitoring—it’s not just install-and-forget,” Panlilio said, adding that MSpectrum will continue to provide support throughout the lifecycle of the project.
Expanding solar capacity and impact
With the completion of the latest installations, Manila Water’s total solar capacity now stands at 6.3MWp, including the 2.5MWp Phase 1 solar project completed earlier this year. \
The consolidated capacity is projected to offset about 5 percent of the company’s annual energy demand, generate long-term cost savings, and contribute to Manila Water’s broader sustainability and resilience goals. —Ed: Corrie S. Narisma
