As a new year approaches, so does our annual workshop on all things telecom.

At PTC ’25, Brianna Boudreau, Jon Hjembo, and Alan Mauldin will return to the conference stage to share fresh insights on pricing, interconnection, submarine cables, bandwidth, and more.

A big part of last year's conversation revolved around resolving the delays in new network supply that had plagued the industry for the last few years, and assessing the “new normal.”

Here’s what the TeleGeography trio will dive into in 2025.

The data center market is in the midst of an unprecedented shift that started—publicly at least—five years ago with the announced moratoria on new development in Singapore and Frankfurt. Those regulatory interventions highlighted the challenges the industry faces in securing sufficient power.

Since then, it turned out that data centers would need much more power than had been realized—just at a time when regulators and community organizations were growing increasingly critical of the sector's existing demand.

Our Data Center Research Service estimates that, as of 2024, colocation operators in the top ten data center markets by MW consume about 13 gigawatts (GW) of power.

That's enough power to generate electricity for roughly 10 million homes—or, in this case, only about 1,000 commercial data centers!

Home to several older but underutilized subsea cables, the Caribbean is a challenging market for operators. With small island nations dependent on subsea, connectivity is vital. As systems age, key stakeholders want new ones, but with difficult business cases, the debate is centering around what end of life means as the old 25-year rule continues to bend.

This is the brief for a panel TeleGeography’s Lilian Lea is moderating next month at Capacity CALA.
