A Solar Facility With a Proven Track Record
GENERAL SANTOS CITY - The Santos Solar Power Plant is located at Sitio Changco in Barangay Siguel/Bawing, General Santos City. The Department of Energy’s 2026 records list the project under Astronergy Development GenSan Inc. as being in commercial operation, with a reported capacity of 20 MW in the department’s awarded-project table. A separate 2026 Energy Regulatory Commission record identifies the facility at 24.96 MW nameplate capacity, with 78,000 solar panels and a commercial operation date of December 3, 2019. These figures explain why the facility is commonly described as a roughly 25-MW solar power plant serving the Mindanao grid.
More Than Thousands of Panels on a Field
The scale becomes easier to appreciate through the equipment involved. ERC records identify the Santos Solar Power Plant as having 78,000 solar panels and 467 inverters, with a 24,960-kilowatt nameplate rating. The facility is also listed by the Independent Electricity Market Operator of the Philippines as a registered 24.96-MWp generation facility in the Mindanao market. Its operating history stretches back to 2019, making it an established solar installation rather than a newly proposed project. For General Santos, that history offers an interesting look at how utility-scale solar can occupy a place within a city better known internationally for fisheries, commerce, and industry.
GenSan’s Solar Story Is Still Developing
The Santos Solar Power Plant is also part of a wider renewable-energy picture emerging around General Santos and neighboring areas. The Department of Energy’s April 2026 list shows the Santos project continuing under commercial operation, while several other solar projects in General Santos and nearby parts of South Cotabato remain in development or pre-development stages. That distinction matters: proposed projects should not be presented as operating facilities. What can be said confidently is that GenSan already has an established large-scale solar plant, while additional renewable-energy proposals indicate continuing interest in the area’s potential. The existing Santos facility therefore provides a concrete example of solar generation already operating within the city.
