WAIVER OF MARCH 2023 EUT MONTHLY 3% STORAGE WITHDRAWAL LIMITATIONS (March 21, 2023)
FOR GAS SUPPLIERS THAT SERVICE EUT CUSTOMERS ONLY
During the month of March, monthly withdrawals from storage for end-use transportation (EUT) customers are limited to 3% of their contract ACQ (see Section E, sheet E-18.00 of DTE Gas Company's tariff).As a result of the ongoing mild temperatures and current storage operations, DTE Gas will waive the monthly withdrawal limit for all EUT customers for March 2023.EUT customers who exceed the 3% of ACQ monthly withdrawal limit during March will not be assessed an Unauthorized gas usage charge, unless the EUT customer uses DTE Gas' system supply (i.e., monthly consumption exceeds the sum of gas in storage and net deliveries to DTE Gas). If this occurs, then Unauthorized gas usage charges will be assessed. All other terms and conditions of DTE Gas Company's Rate Book and Gas Transportation Agreements remain in effect.
DTE requests that customers and gas suppliers proactively watch for updated operational notices on DTE’s eNominator system, the Gas Noms Webpage, and direct emails.
Please contact your DTE Gas account manager with any questions. For scheduling questions, please contact Gas Nominations at 1-833-383-6667.

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.
