40 MW Raghuganga Hydropower Project Connects to National Grid, Boosting Nepal's Energy Security

Nepal's journey towards energy self-sufficiency has received a significant boost with the successful connection of the 40-megawatt (MW) Raghuganga Hydropower Project to the national transmission grid. Developed by Raghuganga Hydropower Limited, a subsidiary of the Nepal Electricity Authority (NEA), this crucial project located in Myagdi district has commenced electricity generation from its two 20-MW units, seamlessly integrating into the national system as of Wednesday.

The electricity generated from the Raghuganga project is now being transmitted through the vital Kaligandaki Corridor 220 kV transmission line, a key infrastructure backbone for evacuating power from various projects in the region. Following this successful integration, the project is set to declare its test production phase, as stipulated by the Power Purchase Agreement (PPA) between Raghuganga Hydropower Limited and the NEA. A successful 15-day test production period will pave the way for the commencement of commercial electricity generation, marking a new milestone in Nepal's energy sector.

Dirghayu Kumar Shrestha, Executive Director of the Nepal Electricity Authority and Chairman of Raghuganga Hydropower Limited, highlighted the immense challenges overcome during the project's construction. He acknowledged the difficult and complex geographical conditions, the unprecedented disruptions caused by the COVID-19 pandemic, and recurring natural disasters like floods. Despite these formidable obstacles, Shrestha emphasized that the project was completed through persistent efforts and unwavering commitment. He further underscored the project's strategic importance, particularly its ability to operate at full capacity for four hours daily during the evening peak demand period. This capability is expected to significantly contribute to managing electricity demand during the dry season, a period when Nepal often faces power deficits and increased reliance on imports. The Raghuganga project is projected to generate an impressive 247.9 million units of electricity annually, with approximately 34% of this output expected during the critical dry months.

The Raghuganga Hydropower Project represents a substantial investment in Nepal's energy future, with an estimated cost of NPR 9.17 billion, excluding interest incurred during the construction period. The financial architecture of the project involved significant investment from the Government of Nepal and the Nepal Electricity Authority, complemented by a concessional loan obtained under a Line of Credit from the EXIM Bank of India. This blend of domestic and international financing underscores the collaborative effort required for large-scale infrastructure development.

The project's development journey was not without its complexities. The Engineering, Procurement, and Construction (EPC) contract for the civil structures and hydromechanical works was awarded to Jaiprakash Associates Limited, India, through an agreement signed on November 21, 2017, which became effective on May 24, 2018. Subsequently, the contract for electromechanical works was secured by Bharat Heavy Electrical Limited (BHEL), India, on October 15, 2019, with its implementation commencing on December 4, 2019. The overall construction supervision was meticulously handled by WAPCOS Limited, India, ensuring adherence to quality and safety standards.

Interestingly, the Raghuganga Hydropower Project initially began under the direct supervision of the Nepal Electricity Authority with an original capacity of 32 MW. However, due to unsatisfactory performance by the initial contractor, the contract was terminated. This led to a strategic decision to enhance the project's capacity to 40 MW and develop it under a "company model" through an NEA subsidiary, a move aimed at improving efficiency and accountability. This revised approach, coupled with new contractual agreements, successfully propelled the project to its completion.

The integration of the Raghuganga Hydropower Project into the national grid is a testament to Nepal's ongoing commitment to harness its vast hydropower potential. It not only adds crucial generation capacity but also enhances the reliability and stability of the national power system. As Nepal continues to strive for energy independence and sustainable development, projects like Raghuganga play a pivotal role in reducing the country's carbon footprint and fostering economic growth by providing a stable and clean energy supply to industries and households alike. This achievement marks a significant step forward in Nepal's ambitious goal of becoming a net exporter of clean energy in the region.
