Regulatory Commission of Alaska: Notice of Utility Tariff Filing (Chugach)

Notice of Utility Tariff Filing

The REGULATORY COMMISSION OF ALASKA (Commission) gives notice that Chugach Electric Association, Inc. (Chugach) filed TA503-8 and TA383-121, the annual update to its generation and transmission (G&T) line loss factor based on operating results for the year ending December 2020.

This update reflects Chugach's acquisition of the Municipality of Anchorage d/b/a Municipal Light & Power and will update Chugach’s G&T calculation in its tariff for Certificate of Public Convenience and Necessity Nos. 8 (South District) and 121 (North District). The updated G&T line loss factor is used for the allocation of system costs in calculating the fuel surcharge and revenue requirement, and for determination of losses associated with transmission wheeling transactions. Chugach proposes a G&T line loss factor (measured at generation) based on 2020 operating results of 2.235 percent. By comparison, the line loss factor was 2.677 percent for 2019 and 2.589 percent for 2018.

This notice does not contain all requested revisions and the Commission may approve a rate or classification which varies from that proposed.
