Unless this coming winter is milder than expected (forecasts call for a colder winter than we are used to seeing here), you can expect a rate hike on your CPS bill.
CPS Energy has released a statement saying that they expect an increase of 9% on the coming winter month bills. This is due in part to the fact that this winter is expected to be quite colder than usual, plus a spike in the cost of natural gas prices.
CPS has stated that they will try to use cheaper sources of energy in order to pass those savings onto you, the consumer. Despite this, you can still expect an increase of $14.57 per month for the average-sized household. The amount your bill increases could be higher or lower depending on your consumption.
