The announcement, which follows other plans unveiled by the US software giant, raises to nearly 6.7 billion euros Microsoft's planned investment in Aragon, regional leader Jorge Azcon told reporters.

It also follows a similar announcement by Amazon which in May said its cloud computing division would invest 15.7 billion euros to expand its data centres in Aragon, where it currently has three operating.

"This is great news for the Aragonese economy," said Azcon, highlighting the economic benefits expected from this investment which he believes will have "a knock-on effect" in attracting other companies.

Microsoft had in October announced its intention to build a data centre campus in Aragon to provide "cloud services to European companies and public bodies" without saying how much investment that would entail.

Citing figures provided by the IDC consultancy, Microsoft said the project with its 88-hectare (217-acre) campus could "contribute to the creation of more than 2,100 technology jobs in Aragon between 2026 and 2030".

"Data centres will undoubtedly play a fundamental role as the first link in the chain... that will generate investment, innovation and a wider range of digital services in our community," Azcon said.

For months now, big tech has been increasing its investment in data centres, where servers are housed to store the huge amounts of information used by both companies and individuals.

This growth is in line with the needs driven by the demand to develop generative artificial intelligence which requires locations with a robust electrical capacity because these data farms consume a vast amount of energy.

In that respect, Aragon is an ideal location given it is a sparsely populated region with ample sunshine and strong wind exposure that is home to both solar and wind farms, and well connected to Spain's communications networks.
