State rules
This docket is a full base-rate review. Selected charges can change on separate schedules without reopening every issue in this case.
Full base-rate review
No fixed recurring interval
A utility initiates a general rate increase by filing a new tariff. It cannot file another general increase for the same service until the prior request is decided or its maximum suspension period expires.
Rate period: Case-specific; Pennsylvania law sets the filing and decision clock rather than a standard single-year or multi-year plan.
Governing rule ↗Between full reviews
Purchased gas cost recovery
Annual rate · quarterly reconciliation
Large gas distributors file an annual gas-cost tariff and quarterly recalculations. Material differences can change the tariff between annual proceedings, with over- and under-collections reconciled.
Governing source ↗Distribution System Improvement Charge
Quarterly updates · annual reconciliation
An approved DSIC can recover eligible distribution investment between base-rate cases. The formula is updated quarterly and reconciled annually, subject to the utility's approved long-term infrastructure plan.
