Current Status of the Tanauan and Maragondon Solar Projects

Both solar plants have progressed beyond construction and are currently operational. The Tanauan facility in Batangas began generating electricity after commissioning milestones in 2024, while the Maragondon plant in Cavite was also connected to the grid. Together, the projects deliver up to 128 MW of renewable electricity, supporting the national transition toward cleaner energy sources and supplying power to thousands of households.

The Philippines continues to expand solar power infrastructure alongside new energy storage investments. For instance, the $268 million ACEN San Marcelino solar park battery storage project in Zambales aims to strengthen grid reliability by integrating large-scale battery storage with solar generation.

Elevating Sustainability: Solar Power Plants in Philippines Surge with Solar Tanauan’s Innovations

The Tanauan and Maragondon solar power plants, boasting a combined capacity of 140 megawatts, will provide electricity to 84,000 households. Furthermore, they will significantly reduce coal consumption by over 100,000 tons annually.

Prime Infra, renowned for its role in infrastructure, celebrated significant solar project milestones. The April 2023 groundbreaking ceremony united stakeholders, suppliers, consultants, and contractors to celebrate this momentous achievement.

Guillaume Lucci, Prime Infra’s President and CEO, expressed great satisfaction in using advanced technology for Philippine solar plants. He emphasized their commitment to pioneering innovative solutions that promise a cleaner energy future. Solar Tanauan leads in using digital twin tech, drone verification, optimized sizing, and 24/7 quality control. Additionally, they’ve implemented a Front End Engineering Design (FEED) process to streamline procurement and construction phases.

Governor Jonvic Remulla of Cavite expressed his optimism about the substantial impact of renewable energy adoption on the future of the Philippines. Representative Collantes of Batangas welcomed the transition to solar energy as a conscious choice that not only benefits the present but also secures the future for generations to come. Mayor Collantes emphasized the pivotal role of public-private collaboration in driving progress and attracting investors, thereby creating valuable job opportunities.

This collaborative commitment highlights Solar Tanauan, Prime Infra, and partners’ dedication to advancing clean energy solutions in the Philippines. Indeed, solar power plants in the Philippines are paving the way for a brighter and more environmentally friendly future.
