The Northeast Frontier Railway (NFR) has crossed 42.1 MWp of total installed solar power capacity as of July 2026, after commissioning a record 23.7 MWp of new solar capacity between January and July this year alone — the highest addition recorded by any zonal railway in Indian Railways during that period. NFR Chief Public Relations Officer Kapinjal Kishore Sharma confirmed the milestone, tying it to the zone's solarisation programme that has been running since 2011.
Within NFR's own network, the Lumding Division — which includes the Guwahati portion of the zone — leads all divisions with a cumulative 17.7 MWp of installed solar capacity, followed by the Rangiya Division at 9.6 MWp, with the Alipurduar, Katihar and Tinsukia Divisions also contributing meaningfully to the zone-wide total.
Background
NFR's solarisation initiative dates back to 2011, part of Indian Railways' broader, long-running push to cut its electricity bill and carbon footprint by fitting rooftop solar panels on station buildings, workshops, and other railway establishments across its zone, which spans Assam, and stretches into neighbouring states and parts of North Bengal and Bihar through its Alipurduar and Katihar divisions. The initiative sits within Indian Railways' stated national goal of becoming a net-zero carbon emitter, a target that has pushed all 17 railway zones to accelerate rooftop and ground-mounted solar deployment on railway land and infrastructure over the past several years.
What makes the FY26 numbers notable is the pace of acceleration: NFR's solar capacity stood at roughly 18.4 MWp as recently as February 2026, meaning the zone has more than doubled its installed capacity within about five months by adding 23.7 MWp — a rate of expansion that outstripped every other zone in the country over the same window and set a new internal NFR record for capacity commissioned in a single financial year.
Key Details
The core figures behind NFR's milestone, as confirmed by the zone's CPRO:
- Total installed solar capacity: 42.1 MWp as of July 2026, cumulative since the 2011 launch of the solarisation programme.
- New capacity commissioned, Jan-July 2026: 23.7 MWp — the highest addition by any zonal railway in India during this period.
- Leading division: Lumding Division (including Guwahati), at 17.7 MWp cumulative.
- Second-highest division: Rangiya Division, at 9.6 MWp cumulative.
- Other contributing divisions: Alipurduar, Katihar and Tinsukia, each adding meaningfully to the zone-wide total.
- Additional capacity in the pipeline: 9 MWp currently under various stages of implementation across NFR's divisions.
On the financial and generation side, NFR's solar installations generated approximately 114 lakh units of electricity during FY 2025-26, delivering savings of around Rs 8.6 crore for the railway. Both figures represent sharp year-on-year jumps — approximately 90% growth in solar energy generation and 95.45% growth in financial savings compared to FY 2024-25, reflecting both the new capacity coming online and fuller-year generation from panels installed in prior years.
At a Glance
| Metric | FY 2024-25 | FY 2025-26 |
|---|---|---|
| Solar power generation | Baseline year | ~114 lakh units (~90% increase) |
| Financial savings from solar | Baseline year | ~Rs 8.6 crore (~95.45% increase) |
| Total installed capacity (cumulative) | ~18.4 MWp (Feb 2026) | 42.1 MWp (July 2026) |
| New capacity added, Jan-Jul | — | 23.7 MWp (highest of all zones) |
| Leading division | — | Lumding: 17.7 MWp |
| Second division | — | Rangiya: 9.6 MWp |
Local Impact
For NFR, which operates across a geographically challenging zone spanning Assam's plains and hills as well as parts of North Bengal, the electricity cost savings translate directly into operational budget relief that can be redirected toward maintenance, safety upgrades, or further green-energy expansion. The Guwahati-inclusive Lumding Division's leadership position is notable given that Guwahati functions as NFR's most significant urban and administrative hub — meaning a large share of the zone's solar rollout is concentrated in and around one of the Northeast's largest railway junctions and passenger hubs.
For the wider region, the milestone is also a visible marker of how railway infrastructure — typically associated with diesel and grid electricity consumption — is becoming a meaningful, if modest, contributor to Assam and the Northeast's renewable energy footprint, alongside separate state-level pushes like APDCL's rooftop solar drive under the PM Surya Ghar scheme, which has separately brought Assam to roughly 415 MW of installed rooftop solar capacity across households and institutions statewide.
What Happens Next
NFR has an additional 9 MWp of solar capacity currently under various stages of implementation across its divisions, which would push the zone's cumulative installed capacity past 51 MWp once completed. Given the scale of the Jan-July 2026 addition, NFR is likely to continue prioritising rooftop and land-based solar deployment at stations, workshops and administrative buildings across Lumding, Rangiya, Alipurduar, Katihar and Tinsukia divisions through the rest of FY26 and into FY27, in line with Indian Railways' broader net-zero carbon emitter target.
Frequently Asked Questions

Northeast Frontier Railway has reached 42.1 MWp of total installed solar capacity as of July 2026, after commissioning a record 23.7 MWp of new capacity between January and July 2026 alone — the highest addition among all Indian Railway zones in that period.
Which NFR division leads in solar installation?
The Lumding Division, which includes the Guwahati portion of the zone, leads with 17.7 MWp of cumulative installed solar capacity, followed by the Rangiya Division at 9.6 MWp.
How much money has NFR saved through solar power?
NFR's solar installations generated about 114 lakh units of electricity in FY 2025-26, saving approximately Rs 8.6 crore — a roughly 95.45% increase in savings compared to the previous financial year.
When did NFR's solarisation programme begin?
NFR's solar power initiative was launched in 2011 and has expanded steadily since, with a sharp acceleration in capacity additions during 2026.
What other NFR divisions are contributing to the solar push?
Alongside Lumding and Rangiya, the Alipurduar, Katihar and Tinsukia divisions have also added meaningfully to NFR's zone-wide solar capacity.
How much additional solar capacity does NFR plan to add?
