Delivery-only utilities

These cents cover delivery charges reported to EIA. In Texas they are the TDU, not the retail plan.

No delivery-only utility in this state meets the data threshold.

EIA state adjustment

Form EIA-861 includes a balancing row for Maryland, utility number 99999. The sales file names that row Adjustment 2025. It is not a company, the ownership field is blank, and the service-territory file lists no counties. The 2025 file does not have a complete residential price on that row. Read the adjustment row.

These utilities stay linked from this page. Most serve fewer than 10,000 residential customers, or the 2025 file is missing a price, a bill, a usage figure, or enough history.
