Weather determines the amount of energy used to heat your home and thus is the major factor in the size of your PCUD bill. Please be aware that the extremely cold spell at the end of December into January means PCUD customers can expect higher than normal January and February bills. When outdoor temperatures are colder, it takes more energy to heat your home. Even if you don’t turn up your thermostat, you use more energy to keep your home at the temperature you are accustomed to daily.
