Technology group Wärtsilä will carry out a power plant expansion project with two Wärtsilä 32 engines for Philippine-based power provider Delta P, Inc (DPI). The engines will extend the DPI plant’s installed capacity from 30 MW to 44.4 MW, thereby enabling the company to meet its power supply agreement requirements with the Palawan Electric Cooperative. The project was offered on a partial engineering, procurement and construction (EPC) basis, and will meet all contractual obligations, such as power output guarantees. The order with Wärtsilä was booked in Q2 2025.
The existing DPI 30 MW plant, located in Puerto Princesa, Palawan, Philippines was originally delivered in 2016. It operates with four Wärtsilä 32 engines, including auxiliaries. The additional two Wärtsilä 32 engines will each operate for an estimated 6,000 running hours per year. Prior to installation, Wärtsilä will carry out all required engine modifications and also supply the latest applicable automation system.
“Palawan Island is one of the biggest off-grid areas in the country, and the additional capacity provided by the Wärtsilä engines will address the current power shortage on mainland Palawan. We are taking this step to expand the plant’s capacity, allowing us to comply with the power supply agreement,” says Mr. Eric Omamalin, President, Delta P Inc.
The full Wärtsilä scope includes all necessary design and engineering work, as well as minor mechanical upgrades to the engines. Auxiliaries to be supplied include the radiators, fuel booster units, medium voltage switchgear, as well as the control and automation system. The scope also includes installation of the mechanical and electrical equipment, and final commissioning of the project.
“This latest collaboration strengthens our trusted, long-term relationship with Delta P and their parent company Vivant Corporation. With our strong presence and local service support in the Philippines we can ensure the engines run efficiently, bringing reliable power to the local people,” comments Ossi Ylinen, Managing Director, Wärtsilä Philippines.
The Wärtsilä engines and equipment are scheduled for delivery in summer 2026, and the expanded plant is expected to be fully operational by August of that year.
