Rate Activity [Abstract]
Rate Activity	Note 11 – Rate Activity Completed Rate Case Proceedings On July 1, 2025, the Company’s natural gas operating subsidiary in Kentucky received an order from the Kentucky Public Service Commission approving the settlement agreement that allowed base rate increases designed to increase total annual operating revenue by $7,700 or 11.2%. New rates went into effect on July 1, 2025. On February 7, 2025, the Pennsylvania Public Utility Commission (“PAPUC”) issued an order approving, with certain minor modifications, the joint petition for non-unanimous partial settlement filed by Aqua Pennsylvania, Office of Consumer Advocate, and other groups, that allowed a base rate increase designed to increase total annual operating revenues by $73,000. New rates went into effect on February 22, 2025. At the time the rate order was received, the rates in effect also included $37,940 in Distribution System Improvement Charges (“DSIC”), which was 6.73% above prior base rates. Consequently, the aggregate annual base rates increased by $110,940 since the last base rate increase and DSIC was reset to zero. During the first six months of 2025, two of the Company’s water utility operating divisions in Ohio and its water and wastewater utility operating divisions in North Carolina also implemented approved base rate increases designed to increase total operating revenues on an annual basis by $5,820. Further, during the first six months of 2025, the Company implemented infrastructure rehabilitation surcharges designed to increase total operating revenues on an annual basis by $10,808 in its water and wastewater utility operating divisions in Pennsylvania and Ohio, by $2,468 in its water utility operating division in New Jersey, and by $542 in its natural gas operating division in Kentucky. On November 21, 2024, Aqua Illinois received an order from the Illinois Commerce Commission designed to provide an increase in revenues of $11,632 or 11.4% on an annual basis. New rates went into effect on December 5, 2024. On October 9, 2024, Aqua New Jersey received an order from the New Jersey Board of Public Utilities that was designed to provide an increase in water rates of $2,250 on an annual basis. The order also approved the recovery of customer-side lead service line replacement costs of $11,535, that have been deferred from April 2021 through June 2024, through the use of a customer surcharge over a three-year period. New rates went into effect on October 15, 2024. On September 12, 2024, the PAPUC issued an order approving the settlement agreement to the general rate case filed by the Company’s regulated natural gas operating subsidiary, Peoples Natural Gas, that allowed base rate increases designed to increase total annual operating revenues by $93,000 or 11.1%. At the time the rate order was received, the rates in effect included various surcharges and credits, such as the DSIC and Tax Cuts and Jobs Act (“TCJA”) amortization credits totaling approximately $21,000 on an annual basis. The order also provided an annualized change in gathering and other operating revenues of approximately $3,000. Consequently, the aggregate annual base rates increased approximately $111,000 as the DSIC was reset to zero, and the TCJA amortization credit, other surcharges and other operating revenues were adjusted. New rates went into effect on September 27, 2024. The order also approved the implementation of a weather normalization adjustment mechanism (WNA), which is applied to customer bills during the heating season of October through May each year. The weather normalization adjustment mechanism is designed to stabilize our residential and commercial customers’ distribution charges by adjusting billings based on temperature variances from average weather, which effectively decreases rates when the weather is colder than average, and increases rates when the weather is warmer than average. The Company expects the weather normalization adjustment mechanism to result in reduced earnings volatility during the heating season. On October 11, 2024, the Pennsylvania Office of Consumer Advocate appealed this rate case to the Commonwealth Court. On February 12, 2025, the Pennsylvania Office of Consumer Advocate discontinued its appeal on all but one non-revenue matter which can potentially be resolved through settlement. On September 12, 2024, the Company’s regulated water and wastewater operating subsidiary in Virginia, Aqua Virginia, received an order from the State Corporation Commission approving an increase in revenues by $5,490 or 23.8% on an annual basis. The Company implemented interim rates in February 2024 and refunded to customers the difference between interim and final approved rates in December 2024. Pending Base Rate Cases On July 30, 2025, the Company’s regulated water and wastewater operating subsidiary in Virginia, Aqua Virginia, filed an application with the State Corporation Commission designed to increase revenues by $7,927 annually. On June 30, 2025, the Company’s regulated water and wastewater operating subsidiaries in Ohio, Aqua Ohio and Aqua Ohio Wastewater, filed applications with the Public Utilities Commission of Ohio designed to increase rates in total by $14,653. On June 20, 2025, the Company’s regulated water and wastewater operating subsidiary in Texas, Aqua Texas, filed an application with the Public Utility Commission of Texas designed to increase rates by $29,149. On April 30, 2025, the Company’s regulated water and wastewater operating subsidiary in North Carolina, Aqua North Carolina, filed an application with the North Carolina Utilities Commission designed to increase rates by $32,847 in the first year of new rates being implemented, then an additional $5,915 and $6,000 in the second and third years, respectively.
