The Week in 5 Numbers: Data Centers Drive Load Growth in PJM and Texas

Latest industry figures show data centers are driving capacity costs and load queue growth, with broader implications for grid planning and regulation.
Published January 9, 2026, Utility Dive’s “The Week in 5 Numbers” highlights key statistics showing how data centers are influencing electricity markets and grid planning in the U.S. In the PJM Interconnection, market monitor data shows that data center load, both existing and forecast, accounted for $6.5 billion, or 40% of the total costs in the most recent capacity auction. In Texas, ERCOT saw its large load queue expand by roughly 300% in the past year, with more than 70% of that growth coming from data center requests. The article also touches on unrelated offshore wind construction freezes, a $1.2 billion MISO transmission project, and Vistra’s acquisition of generation assets, but the core regulatory takeaway centers on the load and capacity pressures data centers are placing on regional grids.
Data center load represented approximately 40% of costs in PJM’s most recent capacity auction.
ERCOT’s large load interconnection queue grew roughly 300% last year, driven largely by data center demand.
More than 70% of ERCOT’s load queue is from data centers, according to system planners.
The article also notes an ongoing offshore wind construction freeze that developers say is costing millions daily.
MISO expects to spend approximately $1.2 billion on a 765 kV transmission project in Wisconsin as part of its long-range plan.

CONCLUSION
Surging data center load growth has emerging regulatory and planning impacts in key U.S. regions, affecting capacity prices, reliability modeling, and interconnection procedures. As PJM and ERCOT confront these dynamics, regulatory responses and planning reforms will be necessary to ensure capacity markets remain efficient and grids can reliably integrate large, concentrated loads. For advanced transmission strategies, including HVDC corridors that span multiple regions, adapting regulatory frameworks to reflect changing load patterns will be essential to maintain system stability, support interconnection fairness, and provide clear pathways for long-term infrastructure investment.
