Philippines president Ferdinand Marcos Jr attended as construction began on what is thought to be the world’s largest power plant to combine solar PV and battery storage.
The Southeast Asian country’s presidential communications office announced last week (21 November) that Marcos Jr. attended the groundbreaking celebration for the Meralco Terra Solar project in Gapan City, about 100 km from the capital Manila.

The project will include 3.5GWp of solar PV generation capacity and a 4.5GWh battery energy storage system (BESS), which will be built across 3,500 hectares of land in the two provinces of Bulacan and Nueva Ecija.
The government has prioritised its speedy development. In August, the national Board of Investments (BOI) fast-tracked Meralco Terra Solar with the issue of a so-called ‘green lane certificate’.
This would expedite the permitting and licensing process for the plant, as reported by Energy-Storage.news. The BOI is an agency of the government Department of Trade and Industry with a remit to stimulate investment into different kinds of projects that align with national policy objectives.
Although at that time, the total cost of the project was estimated to be PHP185 billion (US$3.14 billion), the presidential communications office statement yesterday quoted a figure of PHP200 billion.
In a speech, the president said that the project represents “decisive action towards helping address global warming and climate change.” The Philippines’ main island of Luzon, where Manila and Gapan are both located, has just been struck twice by super typhoon Pepito. According to BBC reporting, it is the sixth typhoon to hit the country within a month.
A claim that the project is the largest in the world appears to hold up.
The world’s biggest solar PV plant is the 5GW Xinjiang Solar project in the northwest of China’s Xinjiang region, which went online earlier this year through state-owned Ürümqi Zhonglvdian New Energy Co Ltd, but does not include battery storage.
Meanwhile, developer Terra-Gen’s Edwards & Sanborn solar-plus-storage project in California, US, is thought to feature the world’s biggest lithium-ion (Li-ion) BESS facility to date at 3,287MWh, alongside 875MWdc of solar PV.
Edwards & Sanborn, built and commissioned in phases, went fully into commercial operation at the beginning of this year.
That said, over in Latin America, a project pairing 2GW of solar PV and up to 11GWh of battery storage is currently being built in seven phases in Chile. Spanish IPP Grenergy is developing the Oasis de Atacama project, and its first four phases are due to be in operation by the end of 2026, with Chinese BESS suppliers BYD and CATL contracted to work on them.
Meanwhile, Meralco Terra Solar is scheduled to go into commercial operation by 2027, Marcos Jr said. It will connect to the grid via an existing 550kV transmission line and later linked to a new-build transmission line in the region.
Last week, Terra Solar Philippines awarded the project’s engineering, procurement and construction (EPC) contract to China Energy Engineering Group (Energy China).

PV Tech has been running PV ModuleTech Conferences since 2017. PV ModuleTech USA, on 17-18 June 2025, will be our fourth PV ModulelTech conference dedicated to the U.S. utility scale solar sector. The event will gather the key stakeholders from solar developers, solar asset owners and investors, PV manufacturing, policy-making and and all interested downstream channels and third-party entities. The goal is simple: to map out the PV module supply channels to the U.S. out to 2026 and beyond.
