Western Wind and Solar Integration Study - Phase 2:
Base Scenario
NATIONAL RENEWABLE ENERGY LABORATORY
Move to new production simulation tool
• Move from MAPS to Plexos because Plexos has capability to optimize around cycling/ramping costs/constraints and ability to model subhourly
• Need to build Plexos model. This is an opportunity to ensure base scenario is realistic and reflects current state of knowledge.
• Start with WECC TEPPC 2019 database, already built by Plexos
• Remember that WWSIS2 is not a siting study, so leveraging other, stakeholder-vetted siting efforts will be useful

WWSIS Phase 1: Siting Scenario
• Held wind energy (10, 20, 30%) and solar (1, 3, 5%) targets constant, as opposed to serving loads with the cheapest renewable source
• Solar was 70% CSP with 6 hrs storage and 30% rooftop PV. No centralized PV.
• Different targets for WestConnect and rest of WECC

Trade-offs in transmission buildouts
• Different siting scenarios behaved similarly in terms of operational impacts, when significant BA cooperation was assumed.
• Therefore we propose to select only one methodology for siting, although we will build it out to different penetration levels.

Build on other efforts
• Include centralized PV – now have reasonable dataset
• WECC considering study requests now and likely to include in next tranche:• 2022 33% RPS (6 GW solar in
S. NV, 9 GW WY wind)• 2032 33% RPS (12 GW WY
wind)• 2022 dataset update by end
Aug
• Last year’s TEPPC 2029 33% RPS• Renewables sited using
Western Renewable Energy Zone (WREZ) model
• Some issues in making this case work

Base Scenario
• Model year• Equal amounts of renewables throughout WECC• More solar especially in southwest• Increase PV from phase 1
• 50/50 split of PV and CSP. PV includes centralized PV plants
• Wind/Solar Siting Scenario • Use WREZ model results – consider starting with 2029 WREZ
