NHPC has achieved a significant operational milestone with the successful launch of a new 250 MW unit at its Subansiri Lower Hydroelectric Project. This development marks substantial progress in the company's plan to bring the entire project to its full operational capacity of 2000 MW.

Project Development Progress

The launch of this new unit represents a crucial step forward in the development of the Subansiri Lower Hydroelectric Project. The project details highlight the scale and importance of this infrastructure development:

Strategic Significance

The addition of this 250 MW unit demonstrates NHPC's continued commitment to expanding India's renewable energy infrastructure. Hydroelectric projects like Subansiri Lower play a vital role in the country's clean energy transition, providing reliable and sustainable power generation capacity.

The successful commissioning of individual units within large-scale hydroelectric projects requires careful coordination and technical expertise. Each unit that comes online brings the project closer to its full operational potential and contributes to the national power grid.

Operational Impact

With this new unit now operational, the Subansiri Lower project moves closer to achieving its full 2000 MW capacity. The systematic approach to bringing units online aims to ensure stable integration with the power grid while maintaining operational efficiency.

The project's progression toward full operations represents a substantial addition to India's hydroelectric power generation capacity, supporting the country's growing energy demands through clean and renewable sources.

Major Milestone Achieved

NHPC Limited has declared the Commercial Operation Date (CoD) of Unit H2 (250MW) of its flagship Subansiri Lower Hydroelectric Project, effective from 00:00 hours on December 23, 2025. This marks a significant milestone for the 2,000MW project located on the Assam-Arunachal Pradesh border.

Project Commissioning Details

The company announced the commercial operation following successful completion of trial runs for the unit. Key details of the commissioning include:

Project Progress and Future Timeline

With Unit H2 now commercially operational, NHPC has successfully brought online the first unit of this strategically important hydroelectric project. The company has indicated that the Commercial Operation Dates for the remaining seven units of the Subansiri Lower HE Project will be communicated in due course.

Overall Project Status

The Subansiri Lower Hydroelectric Project represents one of India's largest hydropower initiatives:

• Total Capacity: 2,000MW across eight units of 250MW each
• Strategic Location: Positioned on the Subansiri River at the Assam-Arunachal Pradesh border
• Project Type: Run-of-the-river configuration for sustainable power generation

Regulatory Compliance

NHPC's announcement comes in compliance with Regulation 30 of SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015. The company has been providing regular updates on the project's progress through multiple communications to stock exchanges throughout the development phase.

Strategic Significance

The commencement of commercial operations at Unit H2 holds substantial importance for India's renewable energy sector:

1. Clean Energy Contribution: Adds 250MW of clean hydroelectric power to the national grid
2. Regional Development: Enhances power supply reliability in the northeastern region
3. Corporate Growth: Represents successful execution of NHPC's largest ongoing project

Investment Implications

The successful commissioning of Unit H2 presents several positive indicators for NHPC:

With the first unit now operational and generating revenue, NHPC is positioned to benefit from increased cash flows while progressing toward full project completion. The systematic commissioning of remaining units will provide sustained growth momentum for the company's hydropower operations.
