Transmission and Delivery Are Material Immediate Monetization Constraints

Claim

Transmission and delivery readiness are material immediate constraints on monetizing available electricity. The evidence does not yet rank transmission conclusively against domestic demand, market access and dispatch constraints in every season.

Evidence

• The NEA Annual Report FY 2024/25 records continued reinforcement of strategic transmission lines, substations and distribution networks while installed generation reached 3,591 MW. This establishes that network expansion remains an active system requirement.
• The eastern Dhalkebar–Inaruwa section of the Hetauda–Dhalkebar–Inaruwa 400 kV Backbone has operated since June 2024, while official NEA outage notices document conductor-stringing work on the Hetauda–Dhalkebar section in early July 2026. The notices do not establish completion or energisation of the western section. See NEA Hetauda–Dhalkebar Construction Notices, July 2026.
• The NEA Annual Report FY 2025/26 says the newly commissioned Markichowk–Bharatpur 220 kV line enables "power evacuation of generators in Marsyangdi basin at their rated capacity", and that Khimti–Barhabise 400 kV strengthens evacuation from the Tamakoshi and Sunkoshi basins (PDF p.13). NEA also names minimising generation curtailment as a challenge, without publishing a volume (PDF p.12). This is direct utility evidence that specific corridors limited delivery, not a national curtailment total.
• On 7 October 2026 NEA's executive director said transfer between Hetauda and Dhalkebar was limited to about 300 MW pending completion of the section, against about 2,000 MW once complete (Spotlight Nepal, 7 Oct 2026).
• Cross-border delivery depends on corridor hardware, project-level approvals and scheduling rules. India Cross-Border Trade in Electricity Guidelines (2018) and India — Energy Relationship with Nepal document that these are separate constraints rather than a single export-capacity number.
• Stranded Generation and NEA Operational-Reporting Portals (2026) show the central measurement gap: annual generation, capacity and trade totals cannot be converted into a national curtailment estimate without plant-level availability, accepted energy, dispatch events and reason codes.

Confidence Rationale

Medium-high. The physical mechanism and the existence of unfinished or constrained delivery infrastructure are well supported. Confidence is not high because the public evidence cannot quantify national curtailed energy, attribute all lost production to transmission, or rank transmission against demand and market-access constraints across all periods.

Unresolved Issues

• Energisation of the Hetauda–Dhalkebar section, announced as imminent in October 2026 but not verified by 4 November 2026.
• Plant-level available energy, accepted energy, curtailed MWh and reason codes.
• Load-flow and N-1 studies showing which transmission or substation elements bind under specific dispatch conditions.
• Separation of domestic network congestion from export approval, scheduling and buyer-absorption limits.

Boundary Conditions

• This claim does not provide a current national curtailment total.
• It does not claim that every low-generation outcome is caused by the grid; hydrology, maintenance, forced outage and plant availability can produce the same observation.
• It does not claim that transmission completion resolves seasonal firmness, storage needs or weak demand.
• “Material constraint” is not a permanent ranking of transmission as Nepal's single largest bottleneck.
