The Wawa project, with an estimated investment of US$2.57 billion, is designed to store up to 6,000MWh of energy daily. It will supply mid-merit and peak power to the Luzon grid, enhancing flexibility and reducing reliance on fossil fuels. Phase 2 involves constructing dams, an upper reservoir, an underground powerhouse, tunnel water conveyance systems, and a switchyard. SMEC’s responsibilities include project management, construction oversight, design reviews, contractual documentation, stakeholder coordination, and compliance monitoring.
SMEC contributed to Phase 1 by providing technical reviews and supervising components like the lower inlet/outlet, gate shaft, and part of the tailrace tunnel. Gabriel Zamudio Jr., SMEC Vice President and Regional Lead for Dams & Hydropower in the Philippines, stated: “In delivering this project, we’re not just building infrastructure – we’re helping shape the future of clean energy in the Philippines.”
Punitha Rajan Doraisamy, SMEC Regional Director for Dams & Hydropower ASEAN & Pacific, highlighted the project’s significance: “Phase 2 of Wawa PSP pushes the boundaries of pumped hydropower engineering. Through precision engineering and adaptive oversight, we’re delivering a solution that supports peak demand and grid flexibility on a national scale.” Recognized as a nationally significant energy initiative, the project is expected to bolster the Luzon grid’s stability and facilitate the integration of renewable energy sources.
The Wawa pumped storage project aligns with the Philippines’ commitment to sustainable energy development. By improving grid reliability and supporting renewable energy adoption, it contributes to the nation’s clean energy transition and long-term energy security objectives.
