Notice of Utility Tariff Filing
The REGULATORY COMMISSION OF ALASKA (Commission) gives notice that Chugach Electric Association, Inc. (Chugach) filed TA436-8, proposing an annual update to its generation and transmission (G&T) line loss factor based on operating results for the year ending December 2016. 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. The updated G&T line loss factor is 2.810 percent. By means of comparison, previous line loss factors (measured at generation) were 2.414 percent and 2.312 percent based on 2015 and 2013 operating results, respectively.
Additionally, Chugach proposes removing “Eklutna Line Losses” from its calculation. Chugach states that Eklutna line losses are no longer relevant to its G&T Loss Factor since the line segment between Briggs and the Eklutna Hydropower Plant was reconfigured to a radial line when Matanuska Electric Association, Inc. separated from Chugach’s system. Chugach also proposes adding International Substation Transformers 1 and 2 to the Transformer Losses table. Chugach states that these transformers serve both Chugach distribution load and G&T customers via the International Generation Station (IG). Therefore, Chugach removed losses associated with distribution load while losses associated with IGT production remain within the total loss factor.
Finally, Chugach proposes making other adjustments to the calculation that have no impact on results, including removing defunct lines and expanding line descriptions.
This notice does not contain all requested revisions and the Commission may approve a rate or classification which varies from that proposed.
