In context: how this plant compares

At 1,000 MW, Khanyazwe Flexpower power station is well above the median gas plant in South Africa (670 MW). Its current lifecycle status is “Pre Construction” — so it is not yet, or no longer, generating at full output. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.
