Public Notice TA355-32 & TA356-32 HEA:
Transmission and Ancillary Service, Transmission Line Loss -
NOTICE OF UTILITY TARIFF FILINGS
The REGULATORY COMMISSION OF ALASKA (Commission) gives notice that HOMER
ELECTRIC ASSOCIATION, INC. (HEA), an electric utility, has filed tariff revisions TA355-32
and TA356-32 in anticipation of the January 1, 2014 termination of its existing all-requirements arrangement with Chugach Electric Association, Inc.
With TA355-32, HEA proposes to add new firm point-to-point transmission and related
ancillary service provisions to its tariff. The proposed inception rates were developed on
a reserved capacity (kilowatt) rather than volumetric (kilowatt-hour) basis. The
proposed tariff provisions were modeled after the Federal Energy Regulatory
Commission Open Access Transmission Tariff, and require two ancillary services to be
purchased for transmission service: scheduling/system control/dispatch, and reactive
power/voltage control.
With TA356-32, HEA proposes to add new tariff provisions governing line losses
resulting from transmitting energy from the Bradley Lake Hydroelectric Plant.
Transmission line losses will be calculated by measuring total HEA generation, total HEA
loads, and the total power flow at each relevant interchange point, and the results will
be compared to losses that would naturally exist on the HEA system if no transmission
service was provided.
