Idaho Public Utilities Commission Taking Comments On Avista’s Integrated Resource Plan

0

Conservation measures and plant upgrades will not be enough to meet energy demand for Avista Utilities' customers over the next 20 years, according to its integrated resource plan filed with the Idaho Public Utilities Commission (PUC). Comments will be taken through Dec. 8.

To meet an anticipated 1.7% yearly growth rate in energy sales, Avista plans to add 750 MW of natural gas-fired generation and 350 MW of wind generation over the next 20 years. It also hopes to save 226 MW of cumulative energy over the next two decades through energy efficiency measures.

New conservation measures should account for 26% of future load growth, according to Avista. The utility does not plan to add any coal-fired generation to its resource

If nothing is done to add generation or conserve current use, Avista estimates it will begin to experience energy deficits by 2018.

Avista anticipates it will gradually add 250 MW natural-gas generation by 2019, another 250 MW by 2024 and another 250 MW by 2027. The plan anticipates an added wind generation of 150 MW by 2012, another 150 MW by 2019 and another 50 MW by 2022.
