Rate Matters [Abstract] |
Rate Matters | 9. Rate Matters From time to time, the Company files applications for rate increases with the PPUC and is granted rate relief as a result of such requests. Most recently, the PPUC authorized an increase in rates effective March 1, 2019. The PPUC permits water utilities to collect a distribution system improvement charge, or DSIC. The DSIC allows the Company to add a charge to customers' bills for qualified replacement costs of certain infrastructure without submitting a rate filing. This surcharge mechanism typically adjusts periodically based on additional qualified capital expenditures completed or anticipated in a future period. The DSIC is capped at 5% of base rates, and is reset to zero when new base rates that reflect the costs of those additions become effective or when a utility's earnings exceed a regulatory benchmark. During its most recent quarterly reporting period, the Company's earnings were below the regulatory benchmark and the Company began recognizing DSIC in June 2021 for bills rendered after July 1, 2021 that included June consumption. The DSIC provided revenues of $25 for the three and six months ended June 30, 2021 and $0 for the three and six months ended June 30, 2020.
