Any facility with 500 kilowatts or more of installed IT power must carry a label showing classes for power usage effectiveness and water usage effectiveness, with the first labels issued by 15 August 2027. The caveat that matters is that a label is not a limit: the regulation grades data centres, it does not yet cap what they may use, and the Parliament and Council can still object before it takes effect.","story":["The threshold is what makes this bite. Five hundred kilowatts of installed IT power is not a hyperscale campus, it is roughly a handful of high-density AI racks, which means the scheme reaches corporate server rooms and colocation halls across the continent and not only the named giants. Every one of them will carry a public class for how much electricity it wastes and how much water it drinks, renewed annually from 15 August 2027. Europe has run this play before, on fridges, on televisions, on buildings, and the pattern is consistent: the label arrives first and is described as information, then the worst classes get banned. The Commission is not hiding the second step. It has thresholds drafted already, 1.5 for power usage effectiveness and 0.4 for water, aimed at new and retrofitted sites.","The report published alongside it is more revealing than the regulation. Of the data centres the Commission believes are legally required to report, 770 did, which is 36 percent. The averages drawn from that minority look respectable, a power usage effectiveness of 1.36 and a renewable energy factor of 0.86, but they are the averages of the facilities that chose to answer, and nearly two thirds of the fleet is missing from the sample. A grading scheme with that much absence in it grades the compliant. Treat the grade as the instrument that makes a cap enforceable, and read the 36 percent reporting rate as the real constraint on all of it."],"trail":[{"d":"MAR 2024","t":"Delegated Regulation (EU) 2024/1364 creates the European database on data centres and the reporting scheme, the first step toward a rating."},{"d":"MAR 27","t":"The Commission opens its call for feedback on the draft rating scheme, with the consultation closing April 23 and adoption then targeted for the second quarter."},{"d":"SEP 16","t":"The United States House votes 417 to 3 to make data centres pay for the power lines built to serve them.
