Wärtsilä, which manufactures and services power sources and other equipment, is set to expand the Delta P, Inc. (DPI) power plant in Puerto Princesa City to help ease recurring power shortages in Palawan and strengthen electricity supply for off-grid communities.
The expansion will add two Wärtsilä 32 engines, increasing the facility’s total capacity from 30 megawatts (MW) to 44.4 MW.
The additional capacity is expected to improve reliability and allow DPI to keep up with growing demand under its supply agreement with the Palawan Electric Cooperative.
Delta P’s plant, built in 2016, currently runs four engines and supplies power to one of the country’s largest off-grid service areas.
The new units will operate about 6,000 hours annually and are part of a broader plan to modernize the facility’s automation and engineering systems.
Wärtsilä will also provide auxiliary equipment and manage installation and commissioning.
The engines are scheduled to arrive by mid-2026, with full commercial operations expected to begin by August that year.
“Palawan faces power shortages,” Eric Omamalin, president of Delta P, told Container News in a story published on October 10.
“These engines will help us meet demand and comply with our power supply agreement,” he added.
The project also signals Wärtsilä’s deeper involvement in Palawan’s energy sector.
“This project strengthens our long-term relationship with Delta P and Vivant Corporation,” Wärtsilä Philippines managing director Ossi Ylinen also told the shipping news.
“Local support ensures efficient operation and reliable power for Palawan residents,” Ylinen added.
