Lipa, Batangas – Advent Upgrade Solar Inc. (AUSI) and Proterial Philippines Inc. signed a 20-year power purchase agreement (PPA), with the latter’s facility in LIMA Estate, Batangas to source power from a 1,587.20 kilowatt-peak ground-mounted solar photovoltaic system. 

Targeted to begin commercial operations in the first quarter of 2027, the project represents the first ground-mounted solar installation within the estate.

“Through this collaboration, we are taking a meaningful step toward reducing our carbon footprint, enhancing energy efficiency, and contributing to the country's transition to a more sustainable energy landscape,” said Proterial Philippines, Inc. President Yoshiaki Yamashita. 

“As a responsible corporate organization, we recognize the growing importance of renewable energy in addressing environmental challenges while supporting long-term economic growth,” he added. “Once operational, the use of the solar PV system is expected to avoid over 1,400 tons of carbon dioxide equivalent annually, or roughly about 28,000 tons over the 20-year term of the agreement.”

Proterial Philippines, Inc. (formerly Hitachi Cable Philippines, Inc. until its 2023 rebranding) is the local manufacturing arm of Japan-based materials manufacturer Proterial, Ltd., and has been a long-standing anchor locator at LIMA Estate  since 1997. 

“We are incredibly proud to partner with you on what is the very first ground-mounted solar facility in LIMA Estate. By pioneering this installation, Proterial is setting a new benchmark for industrial sustainability in the region,” said AUSI Chairperson and Upgrade Energy Philippines President and CEO Ruth Yu-Owen. 

“Together with Proterial and LIMA Estate, we are proving that industrial growth and environmental responsibility can move forward hand-in-hand, and we look forward to building on this partnership over the next 20 years.”
