Gas Cost Recovery Factor Update
We evaluate the Gas Cost Recovery (GCR) factor every month to reflect the cost we expect to pay our natural gas suppliers. Once actual gas supply costs are booked, any cost adjustments are made to the GCR factor — an ongoing "true-up" process resulting in no profit to DTE. By law, the GCR factor is the actual price we pay for the natural gas you use with no markup. The Michigan Public Service Commission reviews and approves the price we charge for gas.
