Kansai Electric has secured a 14% share in the Wawa Pumped Storage Hydropower Project, marking the Osaka‑based utility’s first investment in a pumped‑storage facility outside Japan.
Deal structure and partners
The stake was acquired through PMJVCo Holdings, a subsidiary of Prime Infrastructure Capital (Prime Infra) that owns and operates the 600 MW project in Rizal, Philippines. Under the definitive agreements, Kansai Electric’s interest translates to an effective 12.18% indirect ownership of the hydropower plant.
Legal counsel on the transaction included a consortium of firms. Picazo Law advised the company on local matters, with Maureen Lizarondo leading the team and senior associate Kyle Dee providing support. “Picazo Buyco Tan Fider Santos & Dee (Picazo Law) advised Prime Infra on local matters relating to the transaction, including the conduct of the vendor’s due diligence,” Lizarondo told a regional business law journal.
Milbank represented the firm as well, fielding a team that comprised James Grandolfo, head of the Hong Kong office, and Andrew Whan, the Asia practice group leader of Milbank’s global corporate and M&A group, among others.
PJS Law acted for Kansai Electric, with co‑heads of the energy practice Najha Estrella and Rowena Salonga overseeing the investment. Ashurst Perkins Coie also advised the Japanese utility, led by Singapore‑based partner Kok Jin Ong.
Project significance
The Wawa facility employs variable‑speed pumped‑storage technology, allowing up to 6,000 MWh of daily energy storage. The Department of Energy in the Philippines has issued a Certificate of Energy Project of National Significance, confirming the government’s recognition of the project’s importance.
According to the filing, the project was developed by Olympia Violago Water & Power, a PMJVCo subsidiary in which the company holds the controlling stake. The investment aligns with its broader effort to expand a renewable‑energy portfolio, a point highlighted by Lizarondo, who said the transaction “represents another significant milestone in Prime Infra’s continued expansion of its renewable energy portfolio.”

The cross‑border nature of the deal reflects a broader trend of Japanese utilities seeking overseas renewable assets to diversify generation sources. Earlier moves have involved solar farms in Southeast Asia, suggesting a strategic pattern rather than an isolated case.
The immediate financial impact on Kansai Electric appears modest. The indirect 12.18% interest does not confer operational control, and the company will likely rely on Prime Infra’s management of the plant. The deal’s terms, including any profit‑sharing arrangements, have not been disclosed.
The Philippine government’s certification of the project as a national priority facilitated the transaction, according to the documents.
Future outlook
Analysts note that pumped‑storage facilities can provide grid stability by absorbing excess generation and releasing it during peak demand. The Wawa project’s capacity to store 6,000 MWh daily positions it as a valuable asset for the Philippines’ growing electricity market, which is increasingly reliant on intermittent renewable sources.
For Kansai Electric, the investment may serve as a stepping stone toward deeper involvement in Southeast Asian energy markets.
Stakeholders will watch how the partnership evolves, particularly as the Philippines pushes for greater renewable integration. The plant’s performance and its contribution to national energy security will likely influence future foreign‑direct investment in the region’s power sector.
