Market Growth Factors

Hyperscalers are also investing heavily in the Spain data center market. In May 2024, AWS announced an investment of EUR 15.7 Billion in the Aragon region of Spain, one of the largest single data center investments in European history. The investment will go towards the development of cloud regions, infrastructure, and hyperscale campuses, a sign of the strength of the hyperscaler market in Spain from major global hyperscale players. Besides sustainability, Amazon's plans for renewable energy and job creation in construction, operations and technology services also help consolidate Spain as one of the leading data center markets in Europe. Important investment and the presence of global hyperscalers attract other ecosystem partners, including colocation providers, connectivity providers and enterprise customers seeking proximity to major cloud players.

Renewable energy developments will provide a more cost-effective and stable input for data center facilities in Spain. The increase in solar and wind power generation capacity will give operators a more sustainable source of energy, reducing reliance on variable sources to meet their 24/7 requirements. In May 2024, Digital Realty signed a series of five power purchase agreements (PPAs) in France and Spain for a total of 134 megawatts of solar and wind energy, increasing the sustainability, reliability and energy independence of its European data center portfolio. Outside of meeting the needs of foreign hyperscalers with carbon neutral commitments, renewable power can help to strengthen the electricity grid in developing countries and extend growth beyond their main cities.

The rapid digital transformation of Spanish businesses has generated strong demand for data center space as the financial, healthcare, retail and manufacturing sectors increasingly adopt cloud, real-time analytics and artificial intelligence-enabled capabilities into their modernization strategies. IMARC Group's report states that the cloud computing market in Spain was estimated at USD 5.31 Billion in 2024, and is expected to see growth at a CAGR of 20.00%, in the forecast period (2025-2033). The growth is driven by government-sponsored digital projects in the country. The union of enterprise transformation and focused government policy creates a perfect environment for the data center sector to flourish.
