What the company said
NHPC has declared Commercial Operation (CoD) of Unit#5 of the Subansiri Lower HE Project from 00:00 hours on 23.10.2026. CoD is the point from which a unit is treated as commercially operational.
Project size and units
- Subansiri Lower HE Project is a 2000 MW project, built as 8x250 MW, located in Assam/Arunachal Pradesh.
- Unit#5 is a 250 MW unit.
- The company states that with this, CoD of five units — Unit#1, Unit#2, Unit#3, Unit#4 and Unit#5, 250 MW each — has been declared.
- CoD of the remaining units will be intimated in due course.
Why this matters to a retail reader
Hydro projects are built in stages, and each unit is declared commercially operational separately. A CoD declaration tells the market that the unit has moved from the construction or testing stage to commercial operation, so it can begin contributing to the company's operating capacity. This update covers one more unit of an 8-unit project.
What to keep in mind
The announcement is an operational update. It states which unit has been declared operational and with effect from when, and confirms that the rest of the units are yet to be declared.
