Arizona customers of Southwest Gas will see their monthly home bills rise an average $3.50, or about 9.7%, starting in January after state regulators approved a much smaller increase than the utility had wanted.
The Arizona Corporation Commission approved the new gas rates Wednesday on a 4-1 vote, after cutting millions of dollars in cost recovery for pipe replacement and some of the gas companyâs most recent system improvements.
Southwest Gas filed for new rates with the Arizona Corporation Commission in May 2019, seeking to increase its annual revenue by about $81 million, or 15.6%, to recover more than $667 million in costs for improvements made since its last rate case in 2016.
