What it changes

For an operator, a utility or a community

An operator arguing that data centre load is a small share of any national grid should know that one European country has already passed a quarter. A utility can see what a decade of unconditioned connection produces on a small system. A community anywhere can ask its own statistics office for the same measurement, because Ireland shows that it can be produced from metering data.
