2007 Integrated Resource Plan
The 2007 Electric IRP public process began in February 2006. The plan was filed with the Washington and Idaho utilitiy commissions on August 31, 2007. Please contact Clint Kalich, Avista's Manager of Resource Planning and Power Supply Analysis, with any questions.
2007 IRP Highlights
- The company is currently long on energy and capacity until 2011, this position will be extended to 2017 for energy and 2015 for capacity with the addition of the Lancaster Generation Facility in 2010
- Avista’s Preferred Resource Strategy Model (PRiSM) developed an efficient frontier that balances both portfolio risk and cost considerations
- The Preferred Resource Strategy (PRS) includes 350 MW of CCCT, 300 MW of wind, 35 MW of other renewables, and 87 MW of conservation between 2007 and 2017
- Conservation acquisition is approximately 25 percent higher than in the 2005 IRP
- The PRS no longer includes coal-fired generation; fixed price natural gas takes its place
- Greenhouse gas emission costs are included in the Base Case;
I-937 requirements through 2016 will be met primarily with plant upgrades
