Monday was a bad day for data center planners. In Sacramento, Gavin Newsom signed seven bills. In Brussels, the European Commission proposed a labelling requirement. Same day, no coordination, and the same instrument in both cases: disclose rather than cap.
What California now demands
The seven laws bite in three places. On electricity, data centers have to pay their own share of grid upgrade costs instead of shifting it onto other ratepayers; they fall under state procurement rules and have to bring new clean supply onto the grid. On water, proposed facilities must give local governments and water suppliers information on use, supply, efficiency and drought planning, and pay for any upgrades themselves. On land, they lose their blanket environmental exemptions: anyone seeking judicial streamlining has to demonstrate first that no costs are being shifted and that state energy, water and fuel standards are met.
The bills are AB 1577 (Bauer-Kahan), AB 2383 (Zbur), AB 2469 and AB 2619 (both Papan), SB 886 and SB 887 (Padilla), and SB 1168 (McNerney). Newsom frames the purpose as a question of ownership: Californians stay in the driver’s seat, and anyone profiting from data centers should not do it at their expense.
Brussels hands out grades, not limits
The EU proposal is more cautious. Operators of facilities from 500 kW upward would have to report energy and water efficiency through an EU labelling scheme, plus how their water use relates to local water stress and whether they can give something back to the local energy system, such as waste heat.
What is missing says more. No caps on power or water, not even a requirement to disclose total consumption. The Commission treats the label as a precursor to later minimum standards. Data centers account for around 2.5% of EU electricity use according to a June report, and capacity is expected to more than double by 2030, from 12 to 28 gigawatts. Member states and lawmakers have two months to object, otherwise the rules take effect.
The industry threatens to leave
The Data Center Coalition warns that California’s rules create uncertainty and duplicate requirements, making the state unattractive in what it calls an already declining market. Jobs, clean energy and tax revenue would move to neighbouring states.
It is the standard threat, and weaker than usual this time. The pushback is not coming from Sacramento but from communities — and from Washington, where the House settled the question of who pays for grid upgrades by 417 votes to 3. Move across a state line to escape California and you land in the same mood.
Transparency is what everyone can agree on
Look at what neither side did. Nobody set a limit on how much power or water a data center may consume. Both simply require that someone write it down.
That is the common ground between an industry nobody wants to drive away and voters who read their own electricity bills. What finally moved politics was not the climate, it was the tariff. Newsom’s kill-switch order last week aimed at the models. These seven laws aim at the bill, and they will land a great deal faster.
