At Yotta 2025 in Las Vegas, our founder Nina Sadighi joined an incredible panel alongside Nancy Novak (Compass Datacenters), Peter Gross, Sean James (Microsoft), and Jim Simonelli (Schneider Electric) to tackle one of the industry's hottest topics: "So much power, so little space" — exploring the future of data centers from chip to grid.
A few key themes stood out in our discussion:
Power as the new real estate — Access to reliable energy is now the gating factor for site selection and growth. While utilities can generate enough electricity, grid congestion and years-long interconnection delays are slowing deployment. On-site generation (fuel cells, renewables, and microgrids) is becoming essential for resilience.
The density challenge — Racks pushing 40–100 kW are quickly becoming the norm, changing how we think about risk, redundancy, and cooling. Liquid and immersion cooling are moving from "emerging" to mainstream technologies.
Storage as a core asset — UPS systems are evolving far beyond backup. Today, storage supports peak shaving, load shaping, and renewable integration, improving both uptime and sustainability.
Heat rejection as the silent bottleneck — At these densities, cooling is just as critical as power. We discussed the role of absorption chillers and trigeneration, which use waste heat from on-site generation for cooling — achieving efficiencies up to 95% while reducing both costs and carbon.
The takeaway: addressing data center growth isn't about solving any single issue. Success will require integrated strategies across power, density, storage, and cooling — all working together.
