DATA CENTER & POWER

Grid upgrades could improve power access for data centers

Federal support for existing transmission lines could ease some power bottlenecks. Data-center developers still need to establish when those improvements will reach their particular site.

September 26, 2026

THE DEVELOPMENT

What happened

On September 24, the U.S. Department of Energy selected 31 grid projects across 26 states for proposed support under its SPARK program. The package combines $1.9 billion in federal funding with $3.35 billion from recipients, for $5.25 billion in total investment. [1]

DOE expects the work to unlock more than 23 gigawatts of additional grid capacity through upgrades to existing infrastructure. That includes replacing or rebuilding more than 1,500 miles of transmission lines and installing technologies that improve use of nearly 21,000 miles. This is added ability to move electricity, not 23 gigawatts of newly built generation. [1]

PREMIA VIEW

What this means for operators and investors

For a data-center developer or its fiber provider, the useful question is whether a selected project removes a constraint on the path to a specific customer. A national capacity figure cannot establish that. We would map shortlisted campuses against the upgrades, then seek utility confirmation of the service date and remaining substation, interconnection, and generation requirements before accelerating construction.

WHAT REMAINS UNCERTAIN

Project selection and expected capacity gains do not establish a completed funding agreement, an operating date, or a firm power commitment to a particular data center. Benefits will depend on local conditions and delivery.

DECISION QUESTIONS

Three questions stakeholders should answer now.

  1. 01
    Which selected upgrade actually serves the target site?
  2. 02
    What still has to be built or approved before power is available?
  3. 03
    Can fiber and campus spending follow verified utility milestones?

WHAT TO WATCH

What to watch next

Final awards, recipient schedules, and written utility service commitments that translate the national program into usable local capacity.
