AGT Pipeline Conditions for 1/24/2018


Notice Text:

For Gas Day January 24, 2018, Algonquin Gas Transmission (AGT) has approved and scheduled nominations at each pipeline segment and meter station up to AGT's operational capacity. The following locations have been restricted due to requested nominations exceeding AGT's operational capacity:

AGT has restricted 100% interruptible and approximately 98% secondary out of path nominations that exceed entitlements sourced from points west of its Stony Point Compressor Station (Southeast) for delivery east of Stony Point. No increases in nominations sourced west of Stony Point for delivery east of Stony Point, except for Primary Firm No-Notice nominations, will be accepted.

AGT has restricted 100% interruptible and approximately 99% secondary out of path nominations that exceed entitlements sourced from points west of its Cromwell Compressor Station (Cromwell) for delivery east of Cromwell. No increases in nominations sourced west of Cromwell for delivery east of Cromwell, except for Primary Firm No-Notice nominations, will be accepted.

AGT has restricted 100% interruptible and 95% out of path nominations exceeding receipt entitlements sourced at the Tennessee Gas Pipeline interconnect at Mendon (Meter station 00205). No increases in receipts to Mendon will be accepted.

AGT has restricted 100% interruptible and approximately 80% secondary out of path nominations that exceed entitlements sourced upstream of the G system for delivery on the G system, except for Primary Firm No-Notice nominations, will be accepted.

The OFO effective January 24, 2018 will remain in effect until further notice.

As previously posted, AGT requests that customers/point operators on AGT be aware of the impact non-ratable hourly takes from the system may have in causing delivery pressures reaching lower than desired levels. As a reminder, AGT's system is not designed to sustain delivery pressures above contract levels while making non-ratable/accelerated deliveries above scheduled quantities for more than 6 consecutive hours, to be followed by flows below scheduled quantity for the balance of any 24 hour period.

Although AGT currently has a system wide imbalance management OFO in effect, if customers/point operators don't manage hourly takes from the system, 1) delivery pressures will be impacted and /or 2) AGT may be required to impose further restrictions or courses of action in order to maintain the operational integrity of the system.

Additionally, AGT requires all Power Plant Operators to provide information mandated by FERC Order No. 698. Information required includes the hourly consumption profile of directly connected power generation facilities.

Customers are advised that capacity may become available as the nomination and confirmation process continues throughout the day.

Please contact your Operations Account Representative should you have any questions.
