Managing Consultant, Data Center Strategy
For the data center industry, power availability is no longer just a hurdle, but a true barrier to facility development in a rapidly advancing market.
As traditional electrical grids struggle to keep pace, developers are being forced to rethink how and where facilities are constructed, meaning they must navigate complex utility constraints, public perception and pushback, and larger geographic reshuffling putting emerging regions like Greece on the investment map.
Throughout the interviews, Liolis discusses:
- Why securing adequate power capacity has replaced cost efficiency as the primary challenge for data center developers
- How modern closed-loop cooling systems function to correct misconceptions about water consumption
- Why the transition from saturated Tier 1 hubs toward emerging Tier 2 and Tier 3 markets, including opportunities in Greece and Western Macedonia, is critical
- How alternative energy pathways, such as from "behind-the-meter" solutions, renewable partnerships, and the eventual transition to nuclear power sources, are shaping the future of data center development
