GreenYellow, STOA & DEG Drive Southeast Asia’s C&I Solar Revolution

French impact investment firm STOA and Germany’s development finance institution DEG have joined forces with solar energy expert GreenYellow to jointly operate a commercial and industrial (C&I) solar platform targeting up to 400 MWp of installed capacity across Southeast Asia.

This newly established yieldco, originally initiated by GreenYellow, has officially reached financial close, according to a statement released on Tuesday. GreenYellow will retain a controlling interest with a 51% shareholding, while STOA and DEG will hold 29.7% and 19.3%, respectively.

Headquartered in Singapore, the platform currently manages a portfolio of 189 MWp in operational self-consumption solar projects located in Vietnam and Thailand. With the support of STOA and DEG, the venture aims to scale its portfolio significantly, targeting 400 MWp by the end of 2026.

GreenYellow emphasized that the collaboration combines its technical and operational strengths with STOA and DEG’s financial resources to accelerate the clean energy transition in the region. “This partnership reinforces the company’s leadership in Southeast Asia’s solar energy landscape,” GreenYellow noted.
