May 1, 2018: Update of transmission submarine cable in Straits of Mackinac

On May 1, 2018, upon completion of testing, one 138-kV transmission circuit, line 9903, will be returned to service to re-establish an electrical connection between Upper Peninsula and lower Michigan.  Updated return to service information can be found in the MISO outage scheduler application under CROW reference # 1-17710485. For more information about the Straits Cables event, go to atcatc.wpengine.com/StraitsCables.

April 9, 2018: Electric transmission submarine cables damaged in Straits of Mackinac

On the evening of April 1, 2018, both 138-kV transmission circuits that cross the Straits of Mackinac and electrically connect the Upper Peninsula to lower Michigan tripped offline about 30 seconds apart. The two circuits include a total of two overhead transmission lines that transition on land to six submarine cables. ATC owns the overhead line, riser stations on both ends and the underground and submarine cables.  International Transmission Company (ITC) owns the overhead portion of the lines in the lower peninsula of Michigan.

A patrol of the overhead elements showed no damage. The submarine cables, which contain a mineral-based dielectric fluid for insulation, were monitored overnight, and subsequently it was determined that two of them were releasing fluid. Lack of daylight and unfavorable weather conditions, including icing in the channel and on shore, hindered the damage investigation.  Once it was determined the leaks were in the middle of the channel, American Transmission Company (ATC) valved off the dielectric fluid to these cables to limit its release. These two cables are permanently inoperable. ATC is performing a condition assessment of other four cables in the Straits.

ATC is working with several organizations including the U.S. Coast Guard, U.S. Fish & Wildlife Service, Michigan Department of Environmental Quality, Michigan Department of Natural Resources, National Oceanic and Atmospheric Administration, Environmental Protection Agency, and the Michigan Public Service Commission as it continues to investigate and manage environmental impacts.

ATC is also coordinating with neighboring utilities, the Midcontinent Independent System Operator and Midwest Reliability Organization to determine short-term and long-term reliability plans. ATC has received many inquiries about this outage, and the discussion below addresses those inquiries:

Q: What transmission elements are compromised?

A: Two of six 138-kV submarine cables between Point Le Barbe and McGulpin Point were affected. A third cable is believed to be damaged, but has shown no signs of fluid release. Condition assessment of the three other cables continues.

Q: How many transmission lines are involved?

A: Two 138 kV circuits were affected.  Each circuit has three underground / submarine cables that are approximately 4 miles long crossing the Straits of Mackinac.  Two cables were determined to be releasing dielectric fluid – one on each circuit – and one additional cable was faulted.  Consequently, both transmission circuits across the Straits are currently out of service.

Q: What is the age and condition of these cables?

A: Four of cables were installed in 1975, and two other cables were installed in 1991 / 1992.  These cables have been maintained over their life and have shown to be in good operating condition.  They were recently inspected and tested in 2017.

Q: Does ATC know the cause of the cable failures?

A: ATC is investigating with cooperation of the Coast Guard and other agencies.  The Coast Guard has initiated a marine casualty investigation to determine if vessel activity is the cause of the damage to ATC’s cables.

Q: Does ATC know the extent of the damage to the cables?

A: The two cables that were releasing fluid cannot be repaired and have been rendered permanently inoperable. ATC plans to use a remote vehicle to do an underwater visual inspection as soon as possible to assess the condition of the remaining cables and develop both short-term and long-term solutions to restore these transmission circuits across the Straits of Mackinac in the near future.

Q: When will these transmission circuits be returned to service?

A: A return to service date cannot be determined until ATC can conduct an underwater visual inspection of the cables.  We are hopeful that one circuit can be reestablished between the Upper and Lower Peninsula.  Additional condition assessment will determine the feasibility and timeline. These outages are entered into the MISO outage scheduling system (CROW) under CROW #1-17710483 and #1-17710485. The end dates in the CROW system are tentative and will be updated after the condition assessment is completed.

Q: What type of cables are these?

A: The submarine cables are 500 kcmil Cu – Type CR SCFF submarine cables. Four of the cables were installed in 1975, and two additional cables were installed in 1991 / 1992 by Edison Sault Electric Company. ATC became the owner of these circuits in 2001 upon the formation of ATC.

Q: Are there any operating reliability concerns while these lines are out of service?

A: No.  Both ATC and International Transmission Company (ITC) are studying future operating scenarios as part of the review of both the short-term and long-term solutions to restoring these transmission circuits.

Q: What is the makeup of the dielectric insulating fluid?

A: The fluid is a mineral oil that is used industrywide as an insulator in submarine transmission cable packages of this vintage. Following this event, samples were taken by Mackinac Environmental Technology, sent to a certified lab, with the results provided to the Michigan Department of Environmental Quality and ATC on April 5. Preliminary results of representative dielectric insulating fluid samples from the submarine transmission cables indicate no benzene and no PCBs. Other common ingredients in insulating fluids (VOCs) were detected. The Coast Guard has indicated that given the dilution within the Straits and icing on the shoreline, there is low risk to contact with wildlife and humans.

February 5, 2007: ATC mistakenly failed to timely update organization chart on OASIS
On February 2, 2007, ATC Management Inc., as corporate manager of American Transmission Company LLC (ATCLLC), posted to the OASIS an update of its organization chart. It appears that the OASIS posting may be two days later than the seven business days posting requirement of 18 CFR Part 358.4(b)(3)(iv).

Organizational changes in ATCLLC’s Asset Management department were made effective on January 22, 2007. While the high level organizational changes were announced to Asset Management department employees, details pertaining to specific job titles were still under review and pending decisions, which were finalized on or around January 31, 2007. A corporate-wide announcement of the changes, and the distribution of the revised organization chart, was done on February 2, 2007. Upon the announcement of the organizational change on February 2, 2007, an assessment of the OASIS posting requirements was made. ATCLLC has conservatively concluded that an OASIS posting update should have been made on or before January 31, 2007. Upon recognition that the OASIS posting update was beyond the seven business day posting requirement, ATC expeditiously made an OASIS posting update which added the revised Asset Management department organization chart to the OASIS site on the afternoon of February 2, 2007.

January 30, 2007: The following notice is being posted at the request of We Energies
“At approximately 0735 on January 30, 2007, the WEC Balancing Authority during the course of routine communications with its affiliated generator operator and generator owners inadvertently disclosed an excursion on the system of about 300 MW relating to an unnamed, unaffiliated generator that at the time remained down. While the WEC Balancing Authority does not believe this posting is required, it is made out of an abundance of caution with the intent of compliance with FERC requirements.”

December 12, 2006: Empire-Forsyth 138-kV line rating
ATC has revised the summer ratings of the Empire-Forsyth 138-kV line to 195 MVA normal, 202 MVA emergency. The summer emergency rating is limited by the line conductor clearance.
