A typical usage might be 2,000 kW-hrs, which equates to $258 plus $10 customer charge, $268? Your usage will vary and you should look at your current usage to see how to estimate.
CoServ also operates the gas company and you can find information on it at the same website.
Water is provided by the City of Frisco.
There is a $22 customer charge per month, which includes 2,000 gallons of water in and out. For each 1,000 gallons above that, you pay $5.19.
