Maritime Link - Loss Factor

NSPML has recalculated the Transmission Loss Factor as required by the Emera and NALCOR Transmission Service Agreements.

The calculated loss factor to be applied for Maritime Link transactions for the period above is 4.15%.

Change from Last Period

To calculate the loss factor as outlined in the Energy and Capacity Agreement, transfers from the thirteen-month rolling window of August 2021 to August 2022 as well as estimated station losses for valve cooling, transformer cooling and auxiliary systems are utilized. As this is the first reporting period using the update calculation, the loss factor cannot be directly compared to the previous period.

 

Last period, covering  August 15th, 2022, to September 14th, 2022, inclusive, had a loss factor of 4.60%. The next update will be published by October 10th, 2022.
