Public Notice...


    Pursuant to the Wyoming Administrative Procedure Act and the Wyoming Public Service Commission’s (Commission) Rules, notice is hereby given that a public hearing is scheduled regarding Rocky Mountain Power’s (RMP or the Company) Application of Rocky Mountain Power (RMP or the Company) requesting authority to increase rates on deferred Net Power Costs (NPC) pursuant to Tariff Schedule 95; and to decrease rates pursuant to Tariff Schedule 93, Renewable Energy Credits (RECs) and Sulfur Dioxide (SO2) emission allowances. The public hearing is set to commence on Tuesday, December 1, 2020, at 9:00 a.m., in the Commission’s hearing room located at 2515 Warren Avenue, Suite 300, in Cheyenne, Wyoming.

    RMP is a public utility as defined in Wyo. Stat. § 37-1-101(a)(vi)(C), subject to the Commission’s jurisdiction pursuant to Wyo. Stat. § 37-2-112.

    On April 15, 2020, the Company submitted an Application together with testimony, exhibits and revised tariff sheets requesting authority to revise and change rates pursuant to two different rate schedules: [i] its Energy Cost Adjustment Mechanism (ECAM) Tariff Schedule 95, requesting approval to increase rates by $7.4 million to recover deferred NPC; and, [ii] its REC and SO2 revenue adjustment mechanism (RRA) Tariff Schedule 93, requesting approval to decrease rates by $604 thousand to reflect the sale of RECs and SO2  emission allowances.  The total ECAM deferral from calendar year 2019 was a charge of approximately $13.9 million, which consists of: [i] deferred ECAM costs after the 30 percent (30%) sharing band; [ii] accrued interest of approximately $686 thousand; [iii] a credit of approximately $17 thousand from the 2018 ECAM; [iv] an decrease of approximately $16 thousand from the 2019 ECAM; and, [v] a credit of $100 thousand related to the settlement of the 2017 ECAM.

    On June 9, 2020, pursuant to due notice, the Commission approved RMP’s application on an interim basis.

    The following table summarizes the proposed price changes by tariff rate schedule.  Within each rate schedule, the percentage change to individual customers may be higher or lower than the average due to rate design, customer load factors, and usage characteristics.  The combined effect of the 2019 RRA and ECAM in this Application represents an overall proposed rate increase of approximately $13.9 million or approximately 1.13 percent (1.13%).
