On May 1, 2019, Southwest Gas Corporation (“SWG”) filed an application for a permanent gross revenue increase with the Arizona Corporation Commission (“ACC”). On October 24, 2019, the Company filed an amendment to its application, proposing a $93 million revenue increase. After careful consideration of SWG’s filing and the positions of the other parties in the case, the ACC ized an increase of approximately $37 million, effective January 1, 2021, per Decision No. 77850 (Docket No. G-01551A-19-0055).
The residential basic service charge remains $10.70 per month. As reflected in the Decision, the $37 million increase is equivalent to a monthly bill increase of $3.50 (or 9.68%) for an average residential customer using 24 therms. Actual bills may be higher or lower than this amount, depending on customer usage and other rate adjustments.
