ADB financing first large-scale floating solar PV in hydro reservoir in Viet Nam

The Asian Development Bank (ADB) has signed a $37 million loan agreement with Da Nhim–Ham Thuan–Da Mi Hydro Power Joint Stock Company (DHD) to finance the installation of a 47.5-MW peak floating photovoltaic (PV) solar facility on the man-made reservoir of DHD’s existing 175-MW Da Mi hydropower plant.

The project marks the first large-scale installation of floating solar PV panels in Viet Nam and the largest installation in Southeast Asia, ADB says.

“This project will help to boost the share of renewable energy in Viet Nam’s overall energy mix and decrease the dependence on imported fossil fuels such as coal,” said ADB Private Sector Operations Department Deputy Director General Christopher Thieme. “The pairing of these two clean energy technologies — hydropower and solar — is a simple but a highly innovative achievement, which can be replicated elsewhere in Viet Nam and across Asia and the Pacific.”

DHD, a subsidiary of the Viet Nam Electricity (EVN) Power Generation Corporation 1, owns and operates four hydropower plants: Da Mi, Ham Thuan (300 MW), Da Nhim (160 MW), and Song Pha (7.5 MW). DHD’s total generation capacity is 642.5 MW, about 1.7% of Viet Nam’s total capacity.

“We are proud to be the first company in Viet Nam to construct a floating solar power plant on a hydropower reservoir,” said the Chairman of the Board of DHD Nguyen Trong Oanh. “This project aligns with DHD’s strategy of investing in renewable energy to decrease dependence on fossil fuel, contribute to energy security, mitigate climate change, and promote environmental protection and sustainable socioeconomic development. Hydropower reservoirs in southern Viet Nam have vast solar power potential.”

The financing package includes a $17.6 million loan from ADB’s ordinary capital resources. This is supplemented by $15 million of blended concessional cofinancing provided by the Canadian Climate Fund for the Private Sector in Asia and its follow-on fund, the Canadian Climate Fund for the Private Sector in Asia II. These funds were established by the Government of Canada to encourage private investment in climate change mitigation and adaptation projects in Asia and the Pacific.

The package also includes a $4.4 million parallel loan from the Leading Asia’s Private Infrastructure Fund (LEAP), supported by Japan International Cooperation Agency through a $1.5 billion equity commitment.

ADB is committed to achieving a prosperous, inclusive, resilient and sustainable Asia and the Pacific, while sustaining its efforts to eradicate extreme poverty. In 2018, it made commitments of new loans and grants amounting to $21.6 billion.
