You're wrong. The peak demand depends on a number of factors including what city/town it is, the season, the mix of residential/industrial usage, the time of day and the day of the week [1]. Also, if the peak time includes summer afternoon/evenings from 3pm to 9pm (as it does for several cities), a significant portion of that time is in daylight hours. In January in Sydney, sunset is after 8pm. You have lower (or no) power generation from solar at dusk so say 7pm but that's still 4 of the 6 peak hours where solar is impacting peak usage. Power companies will tend to point to residential peak demand to justify price increases while often just entirely excluding industrial usage that drops off at about the same time. Also, residential power usage (in Australia) is changing as building standards change (ie Australian houses are notorious for their energy ineeficiency, historically) and the rollout of residential solar. Smart meters, energy efficiency and batteries can really put a dent in peak electricity usage and this will only continue given how comparatively expensive Australian electricity is.
