Guwahati: The Northeast Frontier Railway (NFR) has achieved notable progress in solar power generation, reinforcing its commitment to green energy and sustainable development. According to official sources, the total installed solar capacity across NFR has reached 31.890 MWp as of February 2026, since the launch of its solarisation initiative in 2011. Significantly, 22.734 MWp has been added during the current financial year 2025–26 alone, indicating a sharp acceleration in renewable energy adoption.
Among the divisions, Lumding division, including the Guwahati section, has recorded the highest cumulative installation at 13.334 MWp, followed by Rangiya division with 8.941 MWp. Other divisions such as Alipurduar, Katihar, and Tinsukia have also made substantial contributions to the overall capacity. The enhanced solar infrastructure has translated into measurable operational gains. During 2025–26 (till February), NFR has been generating an average of around 9.18 lakh units of solar energy per month, resulting in estimated monthly savings of approximately ₹68.80 lakh. These developments highlight the railway’s focused efforts to reduce its carbon footprint while optimizing energy costs.

In addition, around 19.14 MWp of solar capacity is currently under various stages of implementation across divisions, with major projects underway in Lumding, Rangiya, Katihar, and Alipurduar. The ongoing initiatives reaffirm NFR’s proactive role in supporting Indian Railways’ broader vision of achieving net-zero carbon emissions, while promoting environmentally sustainable and cost-efficient operations.
