Proposal requires large new electricity users, including data centers, to pay their fair share of the infrastructure built to serve them
BALTIMORE, Md. (Sept. 29, 2026) — To help protect Marylanders from paying for electric infrastructure needed by large new energy users, BGE, Delmarva Power, and Pepco filed a required Large Load Tariff with the Maryland Public Service Commission (PSC). The proposal would ensure that large new customers, including data centers, would pay their fair share toward the grid all customers rely on. The filing reflects the companies’ commitment to keeping bills as low as possible for customers through The Exelon Promise while supporting Maryland’s continued growth and evolving energy needs.
The companies submitted this proposal in accordance with Maryland’s Next Generation Energy Act and Utility RELIEF Act. It reflects input from stakeholders participating in the PSC’s Public Conference 72 process, which brings together a wide range of interests to identify practical solutions. The proposal may change given the on-going developments at both the state and federal level, as well as based on future PSC guidance and decisions. The proposal:
– Would ensure that large new customers, including data centers, would pay their fair share toward the grid all customers rely on.
– Provides clear financial safeguards before major transmission and distribution investments are made, while simultaneously protecting grid reliability for customers.
“As Maryland’s energy needs grow, this filing proposes clear customer protections so families and existing businesses are not left paying for large grid investments that may be delayed, scaled back or never move forward. It’s a commonsense approach that protects customers while supporting Maryland’s growing energy needs,” said Rob Leming, vice president of Regulatory Policy and Strategy, PHI.
This filing is intended to ensure that growth happens responsibly, with clear accountability for the costs it creates in a fast-changing energy landscape. It also builds on a broader, company-wide effort to protect customers as large-load demand grows. On Aug. 4, 2026, Exelon announced it secured more than $1 billion in customer protections through Transmission Security Agreements (TSAs) across its utilities. This filing brings those same principles into one official regulatory proposal covering BGE, Delmarva Power and Pepco in Maryland.
The proposal also recognizes that electric utilities have an obligation to plan for future growth and continue to do so through established regulatory processes. However, the rapid emergence of very large individual customers, including data centers, creates new risks that traditional planning processes were not designed to address. This filing is intended to ensure that when infrastructure must be built to serve those customers, existing customers are protected if projected energy use does not happen as expected.
Protecting customers and supporting reliable, affordable energy service remain central to BGE, Delmarva Power and Pepco’s approach under The Exelon Promise. This filing marks the beginning of a regulatory process to evaluate how those protections can be implemented within the broader framework being considered by regulators. As those proceedings continue, BGE, Delmarva Power and Pepco will work with stakeholders to support solutions that deliver meaningful customer protections for regulators to consider.
The PSC will hold a hearing on this matter on October 23, as well as additional hearings on Dec. 8-11, 2026.
