Gas Cost Recovery Factor Update
In August 2016, the Gas Cost Recovery (GCR) rate changed from $0.344 per hundred cubic feet (Ccf) to $0.351 per Ccf. This change was implemented on a bills rendered basis beginning the first billing cycle in August 2016.
We evaluate the GCR factor every month to reflect the cost we expect to pay our suppliers. Once actual gas supply costs are booked, any cost adjustments over or under are made to the GCR factor — an ongoing "true-up" process resulting in no profit to us. By law, the GCR factor is passed on to customers without any profit or markup. Customers pay what we pay for natural gas. The Michigan Public Service Commission reviews and approves the price we charge for gas.
