No. 27887 Service Date: June 18, 2021 DEPARTMENT OF PUBLIC SERVICE REGULATION BEFORE THE PUBLIC SERVICE COMMISSION OF THE STATE OF MONTANA IN THE MATTER OF NorthWestern Energy's Application to Update Base Power Costs and Credits in the Power Costs and Credits Adjustment Mechanism REGULATORY DIVISION DOCKET NO. 2021.04.047 NOTICE OF APPLICATION AND INTERVENTION DEADLINE On April 21, 2021 NorthWestern Energy Inc. ("NorthWestern") filed with the Montana Public Service Commission ("Commission") its Application ("Application") to Update Base Power Costs and Credits in the Power Costs and Credits Adjustment Mechanism ("PCCAM"). In its Application, NorthWestern asserts that the baseline of costs and credits (the "PCCAM Base"), last set in 2019, does not reflect an accurate forecast of NorthWestern's fuel and power costs. NorthWestern seeks Commission approval to update its PCCAM Base and qualifying facility ("QF") costs. The update would result in a $2.28 increase in the monthly bill of a typical residential customer using 750 kilowatt-hours per month. On June 15, 2021, NorthWestern filed a supplement to its Application, which requested Commission approval of a final PCCAM Base that uses recent, forward market prices and includes all capacity contracts entered into prior to a hearing on NorthWestern's Application. Copies of NorthWestern's filings are publicly available online at the Commission's website (http://psc.mt.gov) under Docket No. 2021.04.047. On March 20, 2020, the Commission issued a Notice of Operational Changes in Response to Coronavirus ("Notice"). Under the "Office Closed to Public" section of the Notice, the Commission outlined a temporary change for office closure during business hours. Due to the foregoing, copies of the filings are not currently available at the Commission's business office. Copies of the filings may be available at the office of the Montana Consumer Counsel ("MCC"), which represents consumer interests before the Commission, 111 North Last Chance Gulch, Suite 1B, Helena, MT 59601, telephone (406) 444- 2771.
