Each November, Southwest Gas files its Nevada Annual Rate Adjustment (ARA) Application to establish or modify various surcharges such as the Accumulation of Deferred Interest (ADI) rate in Southern Nevada, Unrecovered Gas Cost Expense (UGCE) rates, system Shrinkage Rates for transportation customers, Imbalance Commodity and Reservation Charges used to calculate transportation customer excess imbalance charges,
General Revenues Adjustment (GRA)
rates, Conservation and Energy Efficiency (CEE) rates, Infrastructure Expansion Rates (IERs), and Contract Transition Adjustment Provision (CTAP) rates.
Southwest Gas’ most recent Nevada ARA filing, submitted to the Public Utilities Commission of Nevada on November 15, 2023, requested authority to decrease rates statewide by approximately $11.4 million. The rate adjustments considered in the ARA typically become effective July 1 of the following year, however, because adjustments in this instance resulted in rate decreases for most rate schedules, the rate adjustments became effective May 1, 2024 to provide more timely rate relief to customers.
