The 2019 plan calls for less coal, more solar and additional transmission from the Pacific Northwest.
BOISE, Idaho — Idaho Power has released its long-term energy plan emphasizing the company’s clean-energy goal while it continues to provide reliable, affordable energy to a growing customer base.
The 2019 Integrated Resource Plan (IRP) was filed with public utility commissions in Idaho and Oregon on June 28. Regulators in both states will set a schedule for public review and comment, and they will provide their own responses later this year.
“This plan shows the way forward as we work toward our goal of providing 100% clean energy by 2045,” said Tess Park, Idaho Power’s Vice President of Power Supply. “We see less coal, more solar and increased transmission capacity from the Northwest, while hydropower remains the backbone of our system.”
The IRP is a 20-year plan that examines the cost, reliability and potential risks of the company’s current energy sources and new resources needed to serve growing demand. Taking input from a public advisory council, outside analysts and the company’s own experts, Idaho Power planners use a sophisticated computer model to evaluate a range of options.
The computer model simulates the entire western energy grid under a variety of conditions, such as changes in natural gas prices, potential costs for greenhouse gas emission, electrical demand and other factors. That analysis examined 24 possible energy-mix portfolios, looking at cost, reliability and risk.
The resulting preferred energy mix calls for exiting five of seven coal-fired generating units the company co-owns by the end of 2026 and connecting 220 megawatts (MW) of solar in the next four years. Bringing the Boardman to Hemingway 500-kilovolt transmission project on-line in 2026 will also add to the company’s available resources.
Those additional resources will be needed to serve an expected increase of approximately 10,900 customers each year during the next two decades. The company projects peak load — the period in the summer when demand is highest — will grow an average of 50 MW per year, and the energy needed will increase over 20 average MW per year.
