What changed
Spain is retooling its plan after pushback from operators, shifting from an abrupt all-day 80% renewable mandate to targets tied to demand bands. Under the draft, data centers need renewables to meet 60% of their electricity use in peak hours labeled P1 until 2029. That threshold steps up to 70% in 2029 and 80% in 2032. The draft also sets a 60% renewable share during P2, the next-highest demand window.
New-build and eligibility rules
The update loosens the "new build" requirement for qualifying green power. Renewable plants can be as old as 36 months, versus 16 months in the earlier draft, and solar projects are carved out of the age limit altogether. Officials say the aim is to prioritize projects with a higher chance of getting built and to deter companies from tying up limited grid capacity without delivering.
The government first put the plan on the table in late August, which sharpened tensions with the industry. The latest proposal is slated to go to a key government consulting body on Tuesday.

Why it matters for investors
Spain has emerged as one of Europe's top data-center hubs thanks to relatively cheap power, drawing capital from Amazon.com Inc., Microsoft Corp., Blackstone Inc., and Merlin Properties Socimi SA. Industry group SpainDC expects IT capacity by 2030 to reach 2.5 gigawatts, which would be close to six times the 2025 level. That growth track is running into political resistance: the government warns data centers could lift electricity costs for other users and argues they add limited value to the wider economy, with Prime Minister Pedro Sánchez labeling them an "extractive" business.
For portfolios with exposure to hyperscale buildouts, renewables, or Spanish utilities, the bottom line is that compliance looks more staggered and potentially cheaper than the original plan, but scrutiny of grid impact and project value is not going away.
