Nepal completes 18-km cross-border power line under MCC compact

Nepal completes 18-km cross-border power line under MCC compact

Built World

The line connects the New Butwal substation to the India border; approvals remain before electricity can flow to India.

September 13th, 2026: 18-km cross-border section construction completed

Overview

Updated Sep 13

Nepal finished building an 18-kilometer, 400-kilovolt transmission line connecting its New Butwal substation to the India border, the first segment of a US-funded corridor designed to carry surplus Nepali hydropower across the frontier. The line was expedited at the request of Nepal's energy ministry and completed on time.

Construction is done, but power is not yet flowing. The line still needs cross-border permits and approvals from grid operators on both sides before it can be energized. That final stretch, not the steel and wire, will determine whether Nepal's generation surplus finally becomes export revenue.

Why it matters

If this line energizes, Nepal can export surplus hydropower to India at 400 kV for the first time, converting chronic oversupply into revenue.

  1. 18-km cross-border section construction completed

    Latest Milestone

    MCA-Nepal finishes the line from New Butwal substation to the India border.

  2. Finance ministry delays extension request

    Administrative

    Kathmandu Post reports the finance ministry has not forwarded MCA-Nepal's one-year extension request to MCC.

  3. 46 towers installed

    Progress

    MCA-Nepal reports 46 of the planned 52-53 towers now in place.

  4. 41 of 53 towers completed

    Progress

    Most towers on the 18-km section finished; foundation work on the rest advanced.

  5. Substation and line construction inaugurated

    Construction start

    Nepal's finance minister and US ambassador jointly inaugurate work on the New Butwal link.

  6. MCC operations resume after freeze

    Recovery

    Administration allows MCC global operations, including Nepal's projects, to continue.

  7. US foreign-assistance freeze halts MCC operations

    Freeze

    Trump-era pause on US aid stalls MCC payments globally, including Nepal.

  8. Transmission line bids cancelled

    Setback

    All bids for the 315-km line were far above the estimated cost; rebidding began.

  9. Nepal parliament ratifies MCC Compact

    Ratification

    Ends years of political standoff over the compact's provisions and terms.

  10. US and Nepal sign MCC Compact

    Agreement

    US commits $500M for roads and transmission lines; Nepal commits $150M (later $197M).

Scenarios

1

New Butwal line energized, first commercial power flows to India

Likely Resolves by Q2 2027

Discussed by: Kathmandu Post, urjakhabar

Both governments and the grid operators clear the remaining permits, and NEA energizes the New Butwal link. Nepal sells surplus hydropower to India at 400 kV, boosting export revenue during the wet season.

2

Permit delays push energization past 2027

Possible Resolves by End of 2027

Discussed by: Nepal Energy Forum

Contested rights-of-way, pending land compensation for some plots, and Indian grid-operator approvals drag on. The line sits energized-ready but idle through the next two seasons.

3

MCC declines extension, rest of 315-km corridor at risk

Uncertain Resolves by Q1 2027

Discussed by: Kathmandu Post, MCA-Nepal officials

If MCC rejects Nepal's one-year extension request, the remaining ~297 km of the transmission corridor may not be completed by the August 2028 compact deadline, leaving the cross-border section as an incomplete spur.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

September 2017 - February 2022

MCC Compact ratification fight (2017-2022)

Nepal's parliament spent more than four years debating the US grant, with leftist parties and street protesters alleging the compact masked a military component. Lawmakers finally ratified it in February 2022 after the US side clarified the aid had no defense-related purpose.

Then

The compact moved forward, and project planning began in earnest.

Now

The political fight delayed implementation by years and left the compact vulnerable to US domestic political shifts.

Why this matters now

The transmission line now nearing completion is the same project Nepali lawmakers almost scrapped over political suspicion.

October 2014 - ongoing

Nepal-India power trade expansion (2014-present)

Nepal and India signed a power trade agreement in 2014, revised in 2018, allowing Nepal to export electricity. Early exports were small and intermittent over aging lower-voltage lines.

Then

Nepal began exporting modest amounts of hydropower to India, mostly during the wet season.

Now

A 400-kV high-capacity link has been the missing piece for exporting power at scale.

Why this matters now

The New Butwal line is the infrastructure that turns a legal right to trade power into physical capacity to move large volumes.

2008-2018

Nepal's load-shedding era ends (2018)

For a decade Nepal's aging grid forced daily rolling blackouts of up to 14 hours. The crisis eased only after a wave of new hydropower plants came online from 2016 on.

Then

Nepal became self-sufficient in electricity generation by 2018-2019.

Now

It now generates a surplus in the wet season but lacks enough transmission and storage to use or sell it all.

Why this matters now

Nepal's problem shifted from making power to moving it; this line is the first high-voltage answer.
