The results for the associated transmission expansion projects follow immediately along with flow information on impacted WECC paths.
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 Renewable Options Under High Load CasesThe Basics
Renewable Options Under High Load Cases Increase WECC-wide load 8% 1 Add: 12,000 GWh to meet WECC RPS 2 3 Add transmission For these regions
Increase WECC-wide load 8% 1 8% 8% increase to peak and energy 10% 10% decrease to energy Higher Load = Additional RPS Energy

1- Check PRM 2 - Add CTs (if needed) = Higher load and new resources
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
3 fewer CTs needed in Basin This makes sense: 3,000 MW wind × 10% = 300 MW to peak = 3 fewer CTs

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