UPDATE: April 8th, 11:00am

The second 700 MW high power pole trip test of the Labrador Island Link is complete. The system performed as expected without any customer outages. Power flows will stay at 675MW and be monitored for the next 12 hours as part of these ongoing tests.

Although early in our analysis, we are pleased with how the Labrador Island Link performed during these tests. This last phase of testing was an important step toward final commissioning of this asset. Thank you for your continued patience—We know you are counting on us to provide safe, reliable energy, and we take that responsibility seriously.

We will have more information in the coming days and weeks.

Newfoundland and Labrador Hydro is continuing to test the Labrador-Island Link this week.

We will be moving through a series of tests beginning March 30th, 2023. We’ll be monitoring the system closely during testing and will keep customers informed on the status of the system if issues arise. Updates will be added to this page, as well as to Facebook and Twitter.

Calibration Tests will be conducted over two days, March 30 and 31, between 8:30am – 6:30pm daily. Following successful completion of these tests, we will move into high power tests at 500 MW on April 1 and 700MW on April 2 and 6, tentatively.

During testing, there is a risk of a customer impact. If there is a power interruption, we are prepared and have supply available to restore customers quickly (typically under 30 minutes).

Running the Labrador-Island Link at higher power levels is an important step toward final commissioning of this asset. We appreciate your patience as we move through this next phase of testing. As we work to strengthen our electricity system, we know you are counting on us to provide safe, reliable energy and we take that responsibility seriously.

The Labrador-Island Link is the transmission line bringing power from the completed Muskrat Falls facility in Labrador to the Soldier’s Pond terminal station on the island.
