• The 2013 appraisal estimated project completion by 31 December 2020.
• For Loan 2990, the original closing date of 30 June 2021 is now revised to 30 December 2028.

Relevance

This is the primary monitoring feed for Tanahu Hydropower Project. It supports package, finance and safeguard tracking rather than reliance on a single overall progress percentage.

Limitations

The project page's last project-data-sheet update, live financial data and individual document dates differ. The appraisal completion estimate, loan closing date, contract award and commissioning are separate milestones and should not be treated as interchangeable. An overall public progress percentage from another source should not be attributed to ADB unless it appears in an ADB document.
