AGT Pipeline Conditions for 6/7/2020


Notice Text:

For Gas Day June 7, 2020, 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% of interruptible and approximately 26% of secondary out of path nominations that exceed entitlements sourced from points west of its Burrillville Compressor Station (Burrillville) for delivery to points east of Burrillville. No increases in nominations sourced from points west of Burrillville for delivery to points east of Burrillville will be accepted, except for Primary Firm No-Notice nominations, will be accepted.

AGT has restricted 100% interruptible and approximately 4% out of path delivery nominations exceeding delivery entitlements at the Tennessee Gas Pipeline interconnect at Mendon (Meter station 00205). No increases in deliveries to Mendon will be accepted.

AGT has restricted 100% interruptible and approximately 42% secondary out of path nominations sourced at the Tennessee Gas Pipeline interconnect at Lincoln (Meter station 00206). No increases in receipts sourced from Lincoln 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 1:
Isolation Dates: June 4 - June 14, 2020

During the isolation dates meters 00027, 00028, 00032, 00057, 00074, 00080, 00089 and 00826 are required to schedule any physical takes from meters 00206 and 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.

Due to MNUS compressor station outage at the Westbrook Compressor Station. AGT has restricted the the following meters to -0-:

00837 - SALEM HARBOR STATION
00215 - SALEM ESSEX CO., MA (ESSEX,MA)
01215 - SALEM ESSEX CO., MA NORTH (ESSEX,MA)

The System wide OFO effective June 6, 2020 will remain in effect until further notice.

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.

AGT may be required to issue system specific and/or hourly OFO's pursuant to General Terms and Conditions Section 26.7(d) to impose further restrictions 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.
