How Idaho Power differs from the Idaho average
Eligibility / billing boundary: Schedule 5 energy charges effective January 1, 2026 are modeled. The tariff notes additional Schedule 54/55/91/95/96/98 adjustments or credits may apply; those are not folded into these base energy-period prices.
The state average is a benchmark, not a substitute for this tariff. A low or high encoded period is a marginal energy price and should not be interpreted as a complete monthly bill unless the page explicitly says whole-bill modeling is supported.
