The Spanish government is drafting new regulations to manage the rising electricity demand caused by artificial intelligence and cloud infrastructure. The proposal targets data centres with at least 1 MW of grid-access capacity, requiring them to match at least 80% of their electricity consumption with additional renewable generation on an hourly basis.

To prevent competition for existing clean energy, the mandate suggests that operators use self-consumption or power purchase agreements with a minimum 10-year duration. Non-compliance may lead to penalties such as the loss of grid-access rights or network and system-charge surcharges of up to 500%. The regulations also aim to address water efficiency, power usage effectiveness, and digital sovereignty by requiring infrastructure operators to be established within the European Union.
