Alsons Shifts Diesel Plant to 98.7-MW Solar

• Alsons Power inks deals with PowerChina to convert Sarangani’s diesel plant into a 98.7MW solar farm—cutting fuel dependence and boosting Philippine renewable capacity.

Alsons Power signed agreements with two units of China’s Power Construction Corporation (PowerChina) to convert an existing diesel facility in the Philippine province of Sarangani into a solar power project.

The plan would replace diesel generation with a 98.7-megawatt photovoltaic park, supporting Alsons’ efforts to reduce reliance on fuel-based power while expanding renewable capacity in the Philippines.

How will Alsons convert PowerChina’s Sarangani diesel plant to 98.7MW solar?

• Alsons Power will take over the existing diesel power site in Sarangani and repurpose it for solar generation instead of burning fuel for electricity.
  
• The target conversion is a 98.7MW photovoltaic (PV) facility, meaning the site’s output will be produced by panels converting sunlight into DC electricity and then into grid-ready AC power.
  
• Alsons’ agreements with PowerChina’s two units cover key development and implementation responsibilities for the repowering project.
  
• The diesel units’ role in day-to-day generation will be phased out as the solar plant comes online, shifting the site’s operating model from fuel delivery and combustion to solar asset operation and maintenance.
  
• During the transition, existing infrastructure at the facility—such as land arrangements, grid interconnection points, and electrical switching components—may be assessed and reused where feasible to reduce costs and schedule.
  
• The project will require design, procurement, and installation of major solar components, including PV modules, inverters, mounting structures, transformers, and protection equipment.
  
• Electrical works will include integration of the PV system with the local transmission/distribution network so the plant can deliver power reliably under Philippine grid requirements.
  
• Construction and commissioning will involve testing of electrical systems, performance verification of PV strings/inverters, and safety checks prior to commercial operations.
  
• Operational planning will focus on long-term renewables management, including routine maintenance for solar modules, vegetation/ground management, and monitoring systems to optimize output.
• The solar conversion is expected to help reduce operational exposure to diesel price volatility and improve energy sustainability by replacing fuel-based generation with a renewable resource.
