The Spanish government is set to pass new legislation requiring data centers to source at least 80 percent of their electricity consumption from new renewable generation on an hourly basis.

First reported by Europa Press, the Spanish government approved the draft decree for fast-tracked legislation. The new requirements are expected to apply to data centers with a capacity of 1MW and more. The Spanish government is expected to put the proposal for public consultation prior to the rules being enforced.

The requirements will be applied to new data center projects, not facilities already operating.

The proposed rules would require data center operators to power at least 80 percent of their facilities from renewable sources until the country’s energy mix reaches 90 percent renewables. The renewable power would be in addition to the facilities' existing generation, with each new MW of capacity requirement matched with equivalent renewable generation installed within 18 months before the data center reaches operational status.
