UAHEL Upper Arun Hydroelectric Project Page

Summary

Official UAHEL project page for the Upper Arun Hydroelectric Project, providing current public project parameters, power-evacuation plan, financing-preparation status, environmental/social status, and target construction schedule.

Key Findings

• UAHEL lists Upper Arun as a 1,063.36 MW peaking run-of-river project, including a 2.36 MW eco-flow plant.
• The current project page reports rated discharge of 235.44 m3/s, rated head of 508.26 m, and average annual energy of 4,518 GWh excluding the eco-flow turbine.
• The project page reports year-round minimum peaking of 697 MW for six hours daily at Q95 inflow.
• Power evacuation is planned through a 5.8 km 400 kV double-circuit line to Haitar substation in Sankhuwasabha.
• UAHEL reports target entry into construction in 2026 and target completion in December 2032.

Relevance

Provides the current project-parameter basis for Upper Arun Hydroelectric Project, replacing the earlier entity-page limitation that no public capacity, design-energy, or timeline parameters were available.

Limitations

• Developer source. This is the project company's own public page and should be cross-checked against NEA annual reports, DoED licenses, lender documents, and environmental approvals.
• Preparation-stage status. The page describes project preparation and target schedule; it does not prove financial closure, PPA execution, or construction commencement.
• Dynamic page. The project page may update without a versioned archive, so numbers should be rechecked during any future deep-research pass.
