Sustainability assessment overview
The Bakun Hydroelectric Project (HEP) began operations in 2011 and was fully commissioned in 2014. Since acquiring the project in 2017, Sarawak Energy (SEB) has extended its sustainability systems to Bakun HEP, strengthening environmental management, stakeholder engagement, and biodiversity initiatives.
An assessment in 2024 identified gaps in meeting the Hydropower Sustainability Standard (HSS), particularly in social and environmental areas. SEB has since taken steps to address these, including improving community engagement, enhancing water quality and dam safety measures, and expanding ESG reporting. Some challenges remain, particularly related to social impacts, but efforts to address them are ongoing.
The public consultation period for the Assessment Report of the Bakun Hydroelectric Project ended on 10 June 2025.
