1 10-Year Study Results California Resource Option

2 Renewable Options Under High Load Cases The Basics Study Concept Starting case: 2022 High Load (PC1-5) –Increase WECC annual energy demand 8% Results in additional 12,000 GWh of RPS resource requirements (per statutes) Model added 12,000 GWh in regions throughout WECC (w/ transmission) Goal Compare different resource and transmission options Total (capital and production) cost comparisons –Will be shown at a later date

3 Add: 12,000 GWh to meet WECC RPS Add transmission Renewable Options Under High Load Cases Increase WECC-wide load 8% 1 2 3 For these regions

4 Increase WECC-wide load 8% 1 8% 8% increase to peak and energy 10% 10% decrease to energy Higher Load = Additional RPS Energy

5 Calculate ratios of planned renewables in TEPPC 2022 Common Case Do not include existing resources Do not include DG IRP and LRS data Apply ratio to study build-out of 12,000 GWh Concept: development trends are best the representation of what could be added to each state More resources available than what is identified in WREZ More granular information from CPUC/CAISO Locate resources using WREZ peer-analysis tool Extrapolation Method Add 12,000 GWh to meet WECC RPS 2

6 Wind Solar PV Solar Thermal Small Hydro Geothermal Biomass RPS Resource Option Studies Breakdown of Incremental 12,000 GWh

7 Higher load and new resources = 1- Check PRM 2 - Add CTs (if needed)

8 PC1-5 High Load PRM Gap 1) Added CTs in 100 MW increments to make up this 11,426 MW PRM Gap 2) CT’s were adjusted in Renewable Options Under High Load studies

10 3 fewer CTs needed in Basin This makes sense: 3,000 MW wind × 10% = 300 MW to peak = 3 fewer CTs

12 Now to the results… 1)Resource assumption overview 2)Portfolio Case generation results (versus PC1-5 High Load) 3)Transmission projects overview 4)Expansion case generation results (versus PC1-5 High Load and Portfolio Case) 5)Path flow results - Reviewed duration plots for key WECC paths. Will show some that are interesting in this presentation.
