The Asian Development Bank (ADB) has approved a $160 million loan to expand solar power generation in Bhutan through the deployment of at least 310 MW of new solar capacity. The project includes 120 MW Wobthang, 40 MW Pedseling, and 150 MW Dramthang solar farms. The initiative also includes 46 km of transmission infrastructure to connect the projects to the national grid.
ADB debt will finance most project costs, including DGPC’s equity investment in the PPP joint venture. In addition, a $500,000 IF-CAP grant and a $1 million ADB technical assistance grant will support green skills training, institutional capacity building, and solar policy development. The project is also expected to mobilise approximately $68.7 million in private equity and commercial debt. The initiative supports Bhutan’s target of achieving 5 GW of solar capacity by 2040.
In June 2026, the ADB approved a $63.44 million financing package to support the deployment of a 250 MW/500 MWh battery energy storage system at Cambodia’s Takeo substation. The financing package comprises a $40 million concessional loan and a $5 million grant from ADB, alongside $18.44 million in co-financing from the Green Climate Fund and the UK through the ASEAN Catalytic Green Finance Facility.
