| Environmental Remediation Obligations [Abstract] | |
| Environmental Commitments and Contingencies | Environmental Commitments and Contingencies We are subject to federal, state and local laws and regulations governing environmental quality and pollution control. These laws and regulations require us to remove or remediate, at current and former operating sites, the effect on the environment of the disposal or release of specified substances. MGP Sites We have participated in the investigation, assessment or remediation of, and have exposures at, seven former MGP sites. We have received approval for recovery of clean-up costs in rates for sites located in Salisbury, Maryland; Seaford, Delaware; and Winter Haven, Key West, Pensacola, Sanford and West Palm Beach, Florida. As of March 31, 2026 and December 31, 2025, we had approximately $3.3 million and $3.1 million, respectively, in environmental liabilities related to the former MGP sites, and related regulatory assets of approximately $0.2 million at the respective balance sheet dates for future recovery of environmental costs from customers. Environmental liabilities for our MGP sites are recorded on an undiscounted basis based on the estimate of future costs provided by independent consultants. We continue to expect that all costs related to environmental remediation and related activities, including any potential future remediation costs for which we do not currently have approval for regulatory recovery, will be recoverable from customers through rates. Remediation is ongoing for the MGPs in Winter Haven and Key West, Florida and in Seaford, Delaware. The remaining clean-up costs are estimated to range from $0.3 million to $0.8 million for these three sites. The Environmental Protection Agency has approved a "site-wide ready for anticipated use" status for the Sanford, Florida MGP site, which is the final step before delisting a site. The remaining remediation expenses for the Sanford MGP site are not material. The remedial actions approved by the Florida Department of Environmental Protection have been implemented on the east and west parcels of our West Palm Beach, Florida, site. These properties were sold to another party in December 2025, and no additional costs associated with remediation of the sites are anticipated.
