9. Risk of Prolonging Coal Plants
SB 350 Studies Predicted 9.8 million tons of CO2 reductions per year (tpy) by 2030 in Regional 3 Scenario.
Study assumed 5,000 MW of “Beyond RPS Wind” would be enticed onto the system.
Without the 5,000 MW of additional wind, 87% of predicted CO2 reductions in 2030 Regional 3 Scenario do not occur, leaving decrease of only approximately 1.3 million tpy.
Compare to just one coal unit: Huntington Unit 1 = 3.3 million tpy
Compare to eight units facing SCRs: 26.5 million tpy.

10. Solutions?
Start Cleaner: PacifiCorp addresses plan for transition of its coal plants.
Start Smaller: Begin regionalization with states that are more closely aligned with power mix and climate goals.
GHG Rules: Develop robust GHG mechanism in regional RSO that will account for GHGs in the region and will ensure that California’s consumption does not result in increased GHG emissions to the atmosphere.
Consider impact to out-of-state energy clearing price
Consider impact to in-state thermal generation
Consider complexity of single market with differently priced products
