Exelon Cuts High-Probability AI Data Center Power Pipeline by 40%
Utility introduces transmission security agreements to weed out speculative projects
Exelon Corporation has slashed its high-probability data center load projection by nearly 40 percent in the second quarter of 2026. The Chicago-based utility has introduced strict transmission security agreements to filter out speculative projects from its grid queue. This major shift highlights a growing effort by utility operators to protect residential ratepayers from the immense infrastructure costs of unverified AI developments.
Key details
During its second-quarter 2026 earnings call, Exelon announced that its "high probability" data center load forecast dropped to 11 gigawatts (GW), down from 18 GW at the end of last year. This nearly 40 percent decline is the direct result of the utility requiring developers to sign Transmission Security Agreements (TSAs). These agreements include strict financial provisions, such as credit obligations, committed revenue contributions, and shortfall payments, to ensure developers bear the financial risk of grid upgrades.
In addition to filtering out speculative workloads, Exelon reduced its overall data center pipeline estimate from 43 GW to 36 GW. As part of this weeding-out process, Exelon subsidiary Commonwealth Edison (ComEd) notified the Federal Energy Regulatory Commission (FERC) on July 24, 2026, that it has canceled a previously approved TSA with PowerHouse Hillwood Holding. The canceled contract was tied to a planned 1.8 GW, $20 billion data center development in Joliet, Illinois.
Why this matters
The rapid expansion of AI has led to an unprecedented surge in power requests, straining regional grids and prompting warnings of supply deficits. However, because developers often submit multiple speculative requests to secure grid capacity, the actual demand has been difficult to quantify. By enforcing TSAs, Exelon is establishing a precedent that prevents speculative projects from clogging the grid queue and shifting multi-billion-dollar infrastructure costs onto existing residential utility customers.
Context
Exelon's actions align with a broader national trend where both regulators and utility providers are tightening rules for large-load integrations. Grid operators like PJM Interconnection have seen capacity prices hit record caps due to rising power demands. Meanwhile, other state and federal leaders have proposed or expanded ratepayer protection pledges to prevent AI infrastructure costs from inflating home utility bills. Exelon’s implementation of TSAs provides a proactive, market-based mechanism to separate viable projects from speculative hype.
What happens next
Exelon plans to continue utilizing TSAs to verify the legitimacy of its remaining 36 GW data center pipeline, of which approximately $1 billion in collateral already backs signed agreements. Regulators and other major utility companies across the United States are expected to closely monitor ComEd's canceled contract at FERC as they consider implementing similar security agreements. This shift could lead to further downward revisions in national AI power demand projections as more speculative projects are weeded out.
