Dear,

Transformers are designed for p.f. 0.8

Even if you make your power factor unity (which may sometime
disturb your source), you can not load transformer up to
100% of its capacity. It will raise threat to your costly
machines. Being good engineer, you should not let your
consumer exceed loading your transformer more than 90 % that
becomes 1350 kW (if p.f. is unity) and 1100kw (if p.f. is 0.8).
