Summary

The Solu Corridor Tingla-Mirchaiya 132 kV line is an operational 132 kV evacuation route whose public map geometry is reconstructed from NEA narrative and anchor points.

The Solu Corridor Tingla-Mirchaiya 132 kV line evacuates generation from the Solu/Okhaldhunga area south toward Mirchaiya. It is operational, but the public route geometry is still lower-confidence than the main 220 kV and 400 kV corridors because the current trace is reconstructed from NEA narrative and anchor points rather than an alignment atlas.

Map Interpretation

The map trace is a corridor-level reconstruction from the source-stated Mirchaiya and Tingla terminals, the Maruwa/Katari reroute context, and the municipal corridor through Okhaldhunga.

It should be read as a faithful directional corridor, not as final engineering alignment.

Confidence

Public decision: default-visible with explicit QA warning.

The line is important and operational, so it remains visible. The warning exists because the geometry is low-confidence and because NEA sources appear to mix route-km and circuit-km: the older yearbook describes a 90 km route, while later inventory-style reporting lists 180 km, likely double-circuit conductor accounting.

Limitations & Controversies

This corridor needs a true route-grade IEE/RAP/alignment source before it can be promoted. Until then, the map should keep the confidence caveat visible.
