AGT Pipeline Conditions for 7/12/2019


Notice Text:

For Gas Day July 12, 2019, 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 36% secondary out of path nominations that exceed entitlements sourced from points west of its Stony Point Compressor Station (Stony Point) 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 78% 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 approximately 33% 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 48% secondary out of path nominations that exceed entitlements sourced upstream of the G system for delivery on the G system. No increases in nominations sourced upstream of the G system for delivery on the G system, except for Primary Firm No-Notice nominations, will be accepted.

As previously posted, as part of its DOT Pipeline Integrity Program, AGT has determined that further detailed investigations are required on its J System Line 1.

Valve Section 4 & 5:
Tentative Detailed Investigations Dates: June 10 - July 14, 2019
Isolation Dates: July 9 - July 14, 2019

During the isolation dates meters 00027, 00028, 00089 and 00826 are required to schedule any physical takes from meter 00271.

Additionally, during the isolation dates, deliveries to meters within the isolated area sourced from outside the isolated area and receipts from meters or head of laterals within the isolated area for delivery outside of the isolated area will not be allowed.

As previously posted, AGT has limited operational flexibility to manage imbalances. AGT requires all shippers and point operators to carefully review demand for gas and schedule gas consistent with daily needs and to tender and receive gas consistent with confirmed nominations regardless of their cumulative imbalance position unless otherwise coordinated with your operations account representative.

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.

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.
