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 is 4.18%.
Change from Last Period
To calculate the loss factor as outlined in the ECA, transfers from the thirteen-month rolling window containing December 2021 to December 2022 as well as estimated station losses for valve cooling, transformer cooling and auxiliary systems are utilized. The loss factor has decreased slightly from the previous report, from 4.19% to 4.18%. This is a result of continuous bipole operation in December.
Last period, covering December 15th, 2022, to January 14th, 2023, inclusive, had a loss factor of 4.19%. The next update will be published by February 10th, 2023.
