An improvement in the storage levels of natural gas isn’t enough to make officials at the Public Service Commission adjust their prediction that Missouri consumers will see high heating bills this winter. PSC Energy Manager Warren Wood is encouraged by the improvement, yet still cautious because production is not keeping up with demand. Wood says consumers need to take steps now to prepare for increased heating bills this winter, especially if the weather turns colder than normal. He says though storage levels have improved, they still are too low and with supplies of natural gas remaining tight, the average heating bill for the entire five months of winter from November to March will likely jump $100 from last year.
