Mobile Gas is going along with the Alabama Public Service Commission's adjustment to its rate structure, which will allow the new rates to go into effect in December.
The PSC voted in July to lower the range of return on equity for the natural gas utility that serves southwest Alabama. The range had been 13.35 percent to 13.85 percent, and the PSC lowered it to 10.45 percent to 10.95 percent.
The utility agreed, and the PSC accepted the company's consent with a unanimous vote Tuesday. The PSC estimates the average residential customer will save $31 annually with the change.
The lower return resulted from a series of public hearings. The PSC will begin the same hearing process Sept. 5 with Alabama Gas, the state's largest natural gas utility.
