Rocky Mountain Power (PacifiCorp) - Wyoming: what it publishes for small generators (qualifying facilities) under PURPA, field by field, with the source for each. Checked on October 4, 2026.
When this may change: No fixed annual cycle printed in the tariff: prices are 'subject to change from time to time'; once 10 MW of resources are acquired under Schedule 37 the Company must file updated pricing within 30 days. In practice RMP files around June 30 (2025 and 2026); the 2026 update (Docket 20000-714-ET-26) is pending.
Rates, eligibility and contract terms change: confirm them with the utility or the state utility commission before relying on them.
