Just last year, Southwest Gas and its stockholders celebrated the largest revenue increase in company history, thanks to the company’s back-to-back rate hikes on Arizona customers in 2022 and 2023. Here we are in 2024 and gas company executives once again are making plans to hike utility bills for the third time in three years! Southwest Gas filed a new rate case at the Arizona Corporation Commission (ACC), seeking a $125.6 million increase to its revenues, which is a roughly 12% rate hike.
