How to Speed Microgrid Development for Data Centers

Two energy giants come together with a new strategy

The global data center boom is colliding head-on with one of the most pressing bottlenecks in the energy sector: access to reliable, timely power. In this episode, host Elisa Wood sits down with Jim Mozell, senior director of strategic partnerships at Siemens Energy, and Juan Colina, data center and IT segment leader at Eaton, to discuss how together they are trying to overcome interconnection delays and provide “speed to power” for microgrids.

While many data center developers scramble for quick fixes—from reviving retired plants to chasing speculative nuclear projects—these two energy giants came together to propose a “power to chip” approach. The result, they say, is faster deployment timelines, optimized efficiency, and a more financially sustainable way to meet AI-driven compute demand.

This conversation explores:

●  Why interconnection delays (often 7–9 years) are driving data centers to rethink power strategies

●  How Siemens and Eaton’s microgrid design enables modular, onsite generation—scalable from 250 MW to a gigawatt

●  The critical role of redundancy, efficiency, and combined-cycle technology in meeting massive compute demand

●  How data centers can shift from being heavy consumers to becoming good grid citizens

●  Global regulatory challenges and opportunities across the U.S. and Europe

●  Why slowing down the “frenzy buying” of energy deals could save operators money and optimize long-term sustainability
