Interim City Manager Marvin Townsend brought up the matter on the April 8 City Council agenda, saying there was little the council could do about the increase.
Center Point Energy had sent a notice to the city that the base charge for natural gas service would increase on May 30.
Residential customers will see their base rates increase by a dollar a month, from the current $16.89 to $17.89.
The general service base rate for commercial customers will go up by $2.03 a month, from $25.91 to $27.96.
The rate for large volume users will jump by $12.54 a month, from $135.55 to $148.09.
Those new rates will not include the price of gas used by customers.
Townsend said all Center Point Energy customers in the South Texas area will see the increases. He said the council could ask the Texas Railroad Commission to suspend the increase for up to 45 days and then hold a full rate hearing if the commission believes a review is necessary.
But the city has not had the ability to appeal a rate increase independently in some time, because of changes in state law.
Townsend said the last time the company increased rates was three years ago, in April 2011.
