I'm neither confirming or denying this is the issue, but if the existing mains was 63mm it would have cost a lot to replace it, also the old mains was delivering most of the water to ground level and 1st story, now it needs to go up considerably higher requiring a greater pressure, 90mm will allow 70% more pressure than 63mm.
My expertise is more of the electrical side of things and I believe that issue was a much simpler and cheaper fix as the capacity of the site is similar to what it was prior to the upgrades, the LED floodlights use around 50% less power than the old discharge ones (and deliver around 30% more lumens), which means that capacity was available for the main stand.
