Philippines constructing $3bn ‘world’s largest’ integrated solar/battery facility
04 December 2024
Terra Solar Philippines – a subsidiary of SP New Energy Corporation, which is also on the archipelago – announced a series of work contracts for what will be a US$3.3 billion integrated solar photovoltaic and battery facility; the ‘largest in the world’ the company said.

The Terra Solar project space stretches across 3,500 hectares, and it’s expected to deliver 3.5GW of solar energy, which will be paired with a 4.5GWh battery energy storage system. In addition to being the ‘largest’ integrated facility, it’s expected to be one of the largest solar farms, overall, once fully operational in 2027.
According to local news reports, Philippine President Ferdinand Marcos Jr attended a groundbreaking ceremony for the project last month. “A 13-kilometer, 500-kilovolt transmission line will connect this project to the power grid, ensuring that clean energy reaches Filipino homes and businesses with efficiency,” he was quoted as saying at the event.
It’s expected to meet 12% of the Philippines’ energy demand, delivered to more than two million households, once operational.
Contracts announced for Terra Solar Philippines’ project
Power Construction Corporation of China (Power China) received an EPC contract on the build. Details allegedly include warranties, defect resolution, and long-term operational and maintenance protocols to ensure reliability and sustainability.
The company will manage the east section of the project, which is said to cover about 1,505 hectares across sections of Gapan, General Tinio and Peñaranda (about 15km north of the capital, Manila). The value of the contract was not available.
US-based Jacobs, an infrastructure engineering and construction company, also announced work on the scheme. The firm is expected to deliver engineering services, technical advice and construction phase services. Financial information was not shared.

Jacobs Vice President Fiachra Ó Cléirigh also noted the project aligned with sustainability initiatives. He said, “The Terra Solar project will significantly reduce the country’s reliance on coal, decrease energy-related emissions and bolster progress toward a more sustainable, secure and resilient energy system. Our work will help scale innovation to make sustainable energy a reality faster and for more people, across the country.”
Jacobs said it will use advanced digital construction management tools and drone technology to manage field tasks, streamline site inspections and track progress across the more than 3,000-hectare site.
“Additionally, Jacobs will oversee supply chain and equipment delivery logistics, expediting the manufacture, inspection, shipping and installation of millions of solar panels,” the company said.
