This slide deck contains results from the 2012 TEPPC Study Program related to the Northwest Resource Option. The results for the associated transmission expansion projects follow immediately along with flow information on impacted WECC paths.

Renewable Options Under High Load CasesThe 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

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 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

3 fewer CTs needed in Basin

This makes sense:

3,000 MW wind × 10% = 300 MW to peak = 3 fewer CTs
