257 MWp Solar Power Plant in Hoa Hoi, Phu Yen Province, Vietnam

One of the largest single operating solar power plants in Vietnam and in Southeast Asia

AFRY was engaged as Owner’s Engineer for the 257 MWp Hoa Hoi Solar Power Plant project in 2018 and was responsible for the engineering review, project management, procurement monitoring, construction and commissioning supervision. Phu Yen TTP Joint Stock Company, affiliated company of B.Grimm Power Limited, developed and operates the power plant.

The project was implemented based on two turnkey packages: one package to cover the complete solar PV plant with a single Solar EPC Contractor, and a second package to cover the terminal substation with a single Substation EPC Contractor.

The power plant delivers electricity to Quang Ngai and Nha Trang cities, as well as to the surrounding areas in the region. This milestone project contributes to the fight against climate change by building climate and disaster resilience and enhancing environmental sustainability, in addition to addressing and reducing social economical inequality.
