Summary
Tamakoshi 3 is a 650 MW survey-stage Tama Koshi project in Dolakha, used in the wiki as a top-capacity and basin-concentration comparator.
Tamakoshi 3 is a 650 MW survey-stage project on the Tama Koshi in Dolakha. It is pinned in Layer: Top-10 Capacity Projects because it is the sixth-largest capacity marker in the display set and sits in the same high-head eastern hydropower geography as Upper Tamakoshi.

Why It Matters
Tamakoshi 3 matters as a scale comparator. At 650 MW, it is larger than the already-commissioned Upper Tamakoshi, but the two projects are at very different delivery stages. The contrast helps the wiki keep capacity and execution separate.
It also matters for basin concentration. Dolakha and the Tama Koshi corridor already carry major hydropower infrastructure; adding Tamakoshi 3 would deepen that eastern-central concentration and increase the importance of transmission evacuation through the Khimti/Tamakoshi grid path.
Status And Timing
The current layer treats Tamakoshi 3 as survey-stage. The IPSDP milestone ladder groups Tamakoshi 3 in the 2036-2040 project window. There is no confirmed construction start in the current wiki evidence set.
Map Interpretation
The marker is a river-aligned project reference derived from a registry point. It is suitable for top-10 capacity comparison, not final project engineering.
Limitations & Controversies
The current evidence set identifies Tamakoshi 3 as survey-stage and does not confirm a construction start, final design, financing, offtake structure, environmental approvals, or route-ready evacuation plan.
