Kimathanka Arun HEP

Kimathanka Arun HEP is a 450 MW survey-stage project on the Arun in Sankhuwasabha. It is pinned in Layer: Top-10 Capacity Projects because it is the eighth-largest marker in the display set and part of the same Arun corridor that makes Arun 3 nationally important.

Summary

Kimathanka Arun HEP is a 450 MW survey-stage project in the upper Arun/Koshi corridor. The page tracks it as a later-horizon top-10 capacity marker linked to the same eastern basin logic as Arun-3.

Specifications

Why It Matters

Kimathanka Arun matters because it extends the Arun corridor story upstream. Arun 3 is the near-term, India-developed 900 MW anchor; Kimathanka Arun is a later-horizon state-promoted project that would add another large block in the same eastern basin.

That makes it important for transmission and sequencing. A 450 MW project in upper Arun geography is not just a generation question; it depends on road access, evacuation planning, environmental constraints, and how the broader Arun cascade is prioritized.

Status And Timing

The current layer treats Kimathanka Arun as survey-stage. The IPSDP milestone ladder groups Kimathanka Arun in the 2036-2040 project window. There is no confirmed construction start in the current wiki evidence set.

Limitations & Controversies

The marker is a river-aligned project reference derived from a registry point. Use it for corridor and top-10 comparison, not final site analysis.

The current wiki evidence does not confirm construction start, final design, financing, environmental and social approvals, evacuation arrangements, or COD timing. IPSDP places the project in a later 2036-2040 window, so it should not be treated as near-term supply.
