Idaho Power Raises Preliminary Forecast for Electricity Demand
Idaho Power’s preliminary planning forecast projects average annual electricity-sales growth of 8.9% over five years, compared with 8.3% in its 2025 resource plan. The utility also reported that large industrial customers increased their electricity use during the third quarter and are expected to continue ramping up. The forecast remains preliminary and covers Idaho Power’s service territory, rather than Treasure Valley alone. For industrial owners and investors, WCG’s takeaway is to confirm a property’s available electrical capacity, potential upgrades and delivery schedule before pursuing power-intensive users.
