i agree with Mr Reddy.
Generator rated at 1000MVA at 0.8 pf 11Kv
In terms of KW the prime mover had been designed for this Gen is 1000 MVA X 0.8 = 800kw, any thing more can destroy your prime mover in the long run
now the alternator part is 1000 MVA AT 11KV
The max amps it can carry is 1000000/1.732/11000= 52.5A /phase
now you can operate the generator at any pf you want as long as you do not exceed 52.5 amps per phase.
