Commitments [Abstract] |
Commitments | 7. Commitments The Company was granted approval by the Pennsylvania Public Utility Commission, or PPUC, to modify its tariff to include the cost of the annual replacement of up to 400 lead customer-owned service lines over nine years from the date of the agreement. The tariff modification allows the Company to replace customer-owned service lines at its own initial cost. The Company will record the costs as a regulatory asset to be recovered in future base rates to customers, over a four-year period. The cost for the customer-owned lead service line replacements was approximately $2,058 and $1,961 through September 30, 2025 and December 31, 2024, respectively, and is included as a regulatory asset. Based on its experience, the Company estimates that lead customer-owned service lines replacements will cost $2,100. This estimate is subject to adjustment as more facts become available.
