2019 Nomination Procedure and Schedule

In 2019, Nicor Gas will again follow an administrative procedure to handle nomination requirements on NYMEX holidays when Nicor Gas is open for business and to better align nomination schedules with market trading in situations where trading for the month has ended.    

Nicor Gas will continue to send a DAILYNOM file each business day containing requirements for the following gas day(s).  However, when Nicor Gas is open for business on NYMEX holidays, or when trading for the month has ended, Nicor Gas will not change the group’s Estimated Use and Daily Delivery Range on those days from what was published as their estimates in the previous day’s DAILYNOM file – except when needed to meet Critical Day requirements, Operational Flow Orders or as needed to meet business or operational needs.  

 

We hope this process continues to streamline operations for suppliers participating in the Customer Select program. Nicor Gas reserves the right to modify this process in the future as needed to meet future business requirements.
