NTPC's 800 MW Patratu Unit #2 enters commercial operation

NTPC said the second 800 MW unit of the Patratu STPP Phase-1, run through subsidiary PVUNL, was declared on commercial operation from 25 June 2026.

What was filed

NTPC informed the exchanges that Unit #2 (800 MW) of the Patratu Super Thermal Power Project, Phase-1, has been declared on commercial operation with effect from 00:00 hours of 25 June 2026. The unit is part of a planned 3x800 MW phase and is operated by Patratu Vidyut Utpadan Nigam Limited (PVUNL), a subsidiary of NTPC. The disclosure was made under Regulation 30 of SEBI's listing rules and continues an earlier intimation dated 18 May 2026.

Effect on group capacity

With this unit commercialised, NTPC stated its group totals — both the installed capacity and the commercial capacity — as updated figures (see the key-facts panel). Commercial declaration marks the point at which a unit's output is formally recognised as part of the company's operating fleet rather than under construction or testing.

Unit capacity: 800 MW
NTPC group installed capacity: 90,857 MW
NTPC group commercial capacity: 89,777 MW

Commercial operation means the unit's capacity is now formally counted in NTPC's commercial fleet, a step that holders may track as part of the group's reported generating base. The filing states only this declaration and the updated group capacity figures, with no financial details.
