Southeast Asia has become one of the most closely watched regions for corporate clean energy deals. As data centers and manufacturing investments spread across the region, global companies are increasingly looking for ways to secure renewable power alongside their expansion plans. The demand is there, but the pathways are still taking shape. Rules differ from market to market, timelines are uneven, and developers often find themselves working with frameworks that are evolving in real time.
These conditions are familiar to Shizen Energy, which has been operating across several Southeast Asian markets after expanding from Japan. Speaking with Rei Ushikubo, Head of Carbon Free Solutions, the focus is on practical considerations: how to gauge the maturity of local regulations, how to work with on-the-ground partners, and how to match project development timelines with corporate demand. That approach is illustrated in Shizen’s first major corporate power purchase agreement (PPA) in the region.
