It depends on what usual residential power factor is.  I am used to
230/400 volt systems serving tens of houses per transformer with very
little air conditioning load.  Power factor was unity at peak loads
and we designed the distribution network on that basis.

There was one city with no gas and open fires discouraged which was
awash in surplus MVAr's because of almost unity residential power
factor and the capacitance of its extensive 66kV and 11kV cable
networks.
