Avista Submits 2017 Electric Integrated Resource Plan
As required by the commissions, Avista produces an electric IRP every two years detailing projected growth in demand for energy and the new resources needed to serve customers over the next 20 years. The IRP is developed through a public process that includes customers, environmental organizations and business groups, elected officials, utility commission staff, and Avista’s energy resource analysts.
The first anticipated resource acquisition is expected in 2026 with the return of demand response programs. The programs will temporarily reduce demand during times of peak energy use which helps delay the acquisition of new generation. Other anticipated future resources are updates to existing thermal plants and a natural gas-fired peaking facility.
In the 2018-2037 IRP timeframe, Avista anticipates customer load growth of 0.5 percent, replacing the 0.6 percent projected growth in the 2015 IRP. The lower load growth and addition of new hydropower contracts are contributing to the delay in the date for new resources which was projected in the 2015 IRP to be by the end of 2020.
“The IRP is a 20-year plan to meet customers’ needs for safe, reliable energy while balancing environmental responsibility, energy efficiency and cost,” said
Some highlights of the 2017 IRP include:
- Avista’s current generation resources remain cost effective and reliable sources of power to meet future customer needs over the next 20 years.
- Energy storage costs are significantly lower than the last IRP which for the first time makes the technology operationally attractive in meeting energy needs in the 20-year timeframe of the 2017 IRP.
- Avista has released a Request for Proposals to develop up to a 15 MW (DC) solar facility for the company’s new Solar Select Program for commercial and industrial customers.
- This study estimates conservation will serve 53.3 percent of future load growth.
Over 50 percent of Avista’s company-owned and contracted generation is from renewable energy, including hydro, wind and biomass. These current generation sources, plus new solar resources represent renewable options available to Avista.
