@paulgc Though I didn't read the ofgem report, a few things to notice: it doesn't say "more than double" but "double". And where did that idea come from? I guess from the idea that the requested capacity is more than the current peak usage. But capacity is not usage. Data centres will certainly shift a big chunk of their load to offpeak, because the cost incentive is there. So it'll increase peak, but not double it. Hopefully an actual expert will give us a proper estimate...
