NHPC starts wet commissioning of Unit-3 at Subansiri project

Dibrugarh: The National Hydroelectric Power Corporation Ltd (NHPC) on Saturday officially commenced the wet commissioning of Unit–3 at the Subansiri Lower Hydroelectric Project (SLHEP). The milestone was marked by the successful run of the 250 MW machine, signalling the start of the synchronisation process for the third unit.Strategically located along the border of Arunachal Pradesh and Assam, the project is a cornerstone of India’s transition towards sustainable energy, utilising run-of-the-river technology.By harnessing the natural flow of the Subansiri river rather than relying on massive reservoirs, the project significantly minimises its environmental footprint, while maximising energy output. The dam is designed to strengthen the national grid and reduce the country’s long-term dependence on fossil fuels.Bhupender Gupta, chairman and managing director (CMD) of NHPC, expressed immense pride in the technical milestone. “This achievement is a testament to NHPC’s engineering excellence and a powerful step towards India’s clean, green and self-reliant energy vision. This progress reflects the unwavering grit of the team in overcoming complex engineering challenges,” Gupta said.The CMD also lauded the project leadership, specifically the team led by Rajendra Prasad, executive director and head of project, urging them to maintain the momentum to ensure timely completion of the remaining units. Once commissioned, the project will supply electricity to 16 states across India.Crucially, the northeast is slated to receive a dedicated allocation of 1,000 MW.
