• Point to Point Seasonal Transmission Loss Factors (PDF), May 1, 2022 through October 31, 2022

2022 System Average Transmission Loss Factor - As of January 5 2022

The System Average Transmission Loss Factor for 2022 is 2.2% of load. This number is reviewed annually. This is the loss factor to be used for Network Integration Service and is applied to the net demand of the eligible customer. Those Network Integration Service customers that are fed from distribution voltages incur an additional 1.75% to account for transformer loss.

 For Point-to-Point Service, the Transmission Provider will seasonally calculate loss factors to be used on a path-by-path basis. A separate document lists Point-to-Point loss factors.

 Per Schedule 9 of the OATT, Transmission Customers are required to provide the losses associated with their service. All Transmission Customers are required to include an amount of additional capacity in their service requests sufficient to carry the losses associated with their service.
