Northwest Firmed Resource Option
This slide deck contains results from the 2012 TEPPC Study Program related to the Northwest Firmed Resource Option Studies. The generation results for the associated transmission expansion projects follow immediately along with flow information for the added transmission.
Hydro FirmingModeling Goal
• Compare different hydro dispatches in different wind conditions given various modeling techniques
• Compare path flows and production costs
Implementation StepsStart with 2022 PC23 NW Resource Option (+12,000 GWh)
1. Increase WECC annual energy demand 8%
2. Add 12,000 GWh of renewables to NW
3. Under the purview of high wind in a particular region, investigate how a nearby region’s hydro responds based on different types of modeling
4. Investigate how the changes listed above impact path flows
Add: 12,000 GWh to meet WECC RPS

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
