Member Notice: Proposed Rate Increase
Beartooth Electric Cooperative’s Board of Trustees is considering a proposed 4.5% total revenue increase, focused solely on updating Energy Charges. All Base Charges, System Charges, and the NorthWestern Energy Transmission Charge remain unchanged. If approved at the January 8, 2026 Board Meeting, the new Energy Charges will apply to electricity used on and after January 1, 2026 (appearing on bills mailed in early February).
This adjustment is part of BEC’s long-term plan to prepare for higher wholesale power costs expected in 2027, helping prevent a large single-year rate jump and keeping future rates more stable. For an average residential member using 843 kWh/month, the change equals about $5.05 more per month.
Members are encouraged to submit comments by December 30, 2025, or attend the January 8 Board Meeting. Full details and rate tables are posted at My BEC → Rate Design. Note, the rate table will become effective upon approval of the proposal.
Here is the Member Notice for review – Member Notice-Proposed Rate Increase

The Effect Of The Rate Structure On You—
What does this mean for your account? It depends on your energy use habits. This adjustment is designed to collect the Co-op’s costs fairly and give Members more control over their electric bills.
