The AI boom needs electricity, and a lot of it. Microsoft Corp. (MSFT) is tackling that reality head-on with a new partnership announced Tuesday with Spanish utility giant Iberdrola, combining renewable energy commitments with cloud technology adoption in a deal that checks multiple strategic boxes.
The agreement includes two long-term power purchase agreements in Spain totaling 150 MW, marking Microsoft's first such deals in Europe. The electricity will flow from the Iglesias wind farm in Burgos and the El Escudo wind farm in Cantabria, supporting Microsoft's ambitious goal of running entirely on renewable energy across Europe.
This isn't just a one-way transaction. Iberdrola is committing to expand its use of Microsoft's Azure cloud platform, deploy Microsoft Copilot across its operations, and implement security and compliance solutions to boost AI adoption throughout the organization. The utility has already migrated key business systems to Azure, signaling a serious commitment to digital transformation and operational resilience.
When you add these Spanish agreements to three previous PPAs Microsoft signed with Avangrid (Iberdrola's U.S. subsidiary), the partnership now encompasses approximately 500 MW of capacity spanning both the U.S. and Europe. That's real scale in the race to power AI infrastructure sustainably.
The Grid Is Feeling the Strain
Microsoft CEO Satya Nadella has been refreshingly direct about the challenge. He recently acknowledged that the company is ramping up data center investments to support AI growth, but warned that the sector's rising energy demands are putting "a lot of pressure" on the electric grid.
Nadella emphasized that AI must earn public approval by delivering broad economic benefits, pushing back against concerns about an AI bubble. He pointed to Microsoft's disciplined approach to AI spending and strong Azure performance as evidence the strategy is working. Azure revenue jumped 40% year-over-year, contributing to a 26% increase in total cloud revenue to $49.1 billion.
The CEO's message is clear: Microsoft's cloud and AI platforms, including Copilot tools, are driving widespread adoption and generating real-world impact that justifies continued investment in AI infrastructure and talent. But the energy equation remains a fundamental constraint that can't be wished away.
Meta Takes a Different Approach
While Microsoft is signing renewable energy deals, Meta Platforms Inc. (META) is trying something more unusual. A November report revealed that Meta is entering electricity trading to secure the massive power needed for its AI expansion.
The social media giant's strategy involves accelerating U.S. power plant construction by signing early, long-term agreements, hedging demand risks, and potentially reselling surplus electricity. It's a more aggressive, hands-on approach to the energy challenge.
The stakes are enormous. Meta's Louisiana data center campus alone requires multiple new gas-fired plants, and nationwide AI data center demand is projected to quadruple over the next decade. CEO Mark Zuckerberg has pledged to invest aggressively in AI infrastructure, even at the risk of overspending. The company initially planned to partner with experienced traders in competitive markets like PJM Interconnection and Midcontinent Independent System Operator.
The contrast between Microsoft's renewable energy partnership model and Meta's electricity trading approach highlights just how creative tech companies are getting as they scramble to power the AI revolution. The grid wasn't built for this level of demand, and everyone knows it.
