US Data Center Developers Deploy On-Site Power to Bypass Grid

U.S. data center development is decelerating as critical power grid limitations and insufficient generating capacity hinder buildouts. A Wood Mackenzie report found that developers added only 25 gigawatts of electricity capacity to their project pipeline in Q4 2025, half the volume of the previous quarter. Despite nearly $1 trillion in commitments to AI infrastructure from hyperscalers like Alphabet, Amazon, Meta, Microsoft, and Oracle, utilities are struggling to keep pace with tech ambitions.

To bypass bottlenecks, data center developers are implementing on-site power solutions. Oracle is utilizing behind-the-meter natural gas for Stargate campuses, and xAI has used temporary gas turbines for its Colossus infrastructure. These temporary measures have drawn scrutiny from the United States Environmental Protection Agency over emissions and regulatory loopholes.

Developers are increasingly deploying battery energy storage systems (BESS) to avoid grid connection delays that can last three times longer than facility construction. By utilizing "bring your own capacity" (BYOC) programs and flexible grid connections (FGC), developers can potentially shorten wait times by three to five years. Portland General Electric has already applied these models, including a 30 MW/60 MWh battery solution for a project in Hillsboro, Oregon. Experts suggest a transition toward a hybrid power model, combining bulk power from gas turbines with the instantaneous response of BESS to meet the reliability needs of AI-intensive applications.
