In unfastened rhythm operation, the unit will present a nett capableness of 292.95 MWe, with a nett ratio of 39.5%.

In the 2nd phase, the conversion into a combined rhythm state turbine (CCGT) unit will beryllium completed, with the installation of a vigor betterment steam generator (HRSG), which will beryllium connected to the state turbine exhaust stack astatine its base. The generated steam will provender a steam turbine (ST) with a nominal capableness of 144.05 MWe, to beryllium installed adjacent within the turbine hall.

Under combined rhythm operation, the works will person a gross nominal capableness of 438.60 MWe and a gross ratio of 59.60%, while nett capableness will scope 430 MWe, with an estimated nett ratio of 58.44% under section notation conditions. The timeline foresees the commencement of first-phase works successful the coming August, with the unit entering trial cognition successful October 2027 and commercialized cognition pursuing successful December of the aforesaid year.
