Study Results California In-State Net-ShortCalifornia Out-State Net-ShortCalifornia Out-State Net-Short w SWIP N This slide deck contains results from the 2011 TEPPC Study Program. This study shows the results of moving renewable resources inside and outside of California and there transmission impacts.
Central Question: What is the impact on transmission congestion and generation dispatch of replacing out-of-state resources assumed in the California (CA) renewable resource portfolio in the 2022 Common Case with additional in-state resources? Change to starting input assumptions:Loads – NoneTransmission System – NoneGeneration – 6,201 GWh of out-of-state CA RPS resources replaced by in-state renewables 2022 PC2 In-State CA RPS Net-Short Sensitivity
Net short calculation:RPS requirement (33% of eligible retail sales) = 88,268 GWh less Existing renewables as of 12/31/2010 = 42,826 GWh Net short = 45,442 GWhIn-state net-short resources = 33,889 GWh, or 74% of total net-short resources2022 Common Case In-state vs. Out-of-state CA Net-short Resources
Strategy for Removing Out-of-State Resources Utilized CA CPUC modified cost-constrained resource stackDid not adjust TEPPC under-construction resourcesDid not adjust CPUC discounted core resourcesResulting out-of-state resources replaced: 1,787 MW for 6,201 GWhNew in-state/out-of-state split by energy: 87%/13% Net Zero
Utilized CA CPUC modified cost-constrained resource stackSelected only in-state resources Portfolio mix of additional in-state resources: 1,078 MW for 6,201 GWhStrategy for Adding In-state RPS Resources Net Zero
Resulting Load/Generation Balance Out-of-state CA RPS resources removed from analysis, replaced by additional in-state RPS resourcesNo deficits resulted Load Gen

Central Question: What is the impact on transmission congestion and generation dispatch of replacing in-state resources assumed in the California (CA) renewable resource portfolio in the 2022 Common Case with additional out-of-state resources? Change to starting input assumptions:Loads – NoneTransmission System – NoneGeneration – 11,168 GWh of in-state CA RPS resources replaced by out-of-state renewables2022 PC3 Out-of-State CA RPS Net-Short Sensitivity
Strategy for Identifying In-state RPS Resources to Replace Utilized CA CPUC modified cost-constrained resource stackDid not adjust TEPPC under-construction resourcesDid not adjust CPUC discounted core resourcesResulting in-state resources that could have been replaced: 4,720 MW for 15,709 GWh11,168 GWh (3,265 MW) of resources shifted for an in-state/out-of-state split (by energy) of 50%/50% More than in-state sensitivity (still net zero though)
