The Sephu Solar Power Plant has so far injected about 13.55 million units of electricity into the national grid, with the highest monthly generation of 3.30 million units recorded in December.
According to Ministry of Energy and Natural Resources (MoENR), this trend is expected to continue for the next few months, helping to complement hydropower generation and reduce electricity imports.
The plant is designed to generate around 33 million units of energy per year, and according to MoENR, based on current trends, it is on track to meet the projected output.
The plant plays a key role during the winter lean season, when hydropower plants operate at their lowest capacity due to reduced river flows. In contrast, the Sephu plant is operating at its maximum rated capacity during this period, conforming with seasonal shortages. Over a year, the plant is expected to generate 33 million units, mainly during the lean season, which would otherwise need to be imported from India.
The total installed capacity of the Sephu Solar Project is 22.38 MWp, with Phase I at 17.38 MWp and Phase II at 5 MWp. Phase I was commissioned on 19th July 2025, and Phase II on 3rd November 2025. As of 4th February 2026, the plant had generated a total of 13.55 million units of energy.
Phase II experienced a delay of about one month, mainly due to incessant rainfall during the monsoon season, which slowed earthworks and piling activities, particularly in waterlogged and hilly areas. To address these challenges and avoid further delays, additional foreign technical experts were deployed to work alongside local staff to speed up installation. The contractor also extended working hours to fast-track critical activities and keep the project on schedule.
