Renewable and Efficiency Technology Integration
Can we integrate 35% wind and solarin the West? Goal - To assess the operating impacts and economics of wind and solar on the WestConnect grid
• How do local resources compare to remote, higher quality resources via long distance transmission?
• Can balancing area cooperation help manage variability?
• Do we need more reserves?
• Do we need more storage?
• How does geographic diversity help?
• What is the value of forecasting?
Renewable and Efficiency Technology Integration
What WWSIS is Not
• Not a transmission planning study• Not a cost-benefit analysis
o Capital costs for wind, solar, or conventional generation build-out not included in operational cost impacts
• Not a reliability study• Does not address dynamic stability • Not an optimization study
Renewable and Efficiency Technology Integration
Study Methodology
1. Develop high temporal and spatial resolution wind and solar datasets
2. “Site” wind and solar plants and interconnect them into the transmission and distribution system
3. Conduct operational analysis for system with high penetration wind and solar
4. Quantify operational challenges and benefits

30% Wind/5% Solar Scenarios
•In-Area - each state meets target from sources within that state
•Mega Project - concentrated projects in best resource areas
•Local Priority - Balance of best resource and In-Area sites

How does the system operate with 35% wind and solar?
Mid-July
The operator now manages to load but would have to manage to net load
Load
Net Load = Load - Wind - Solar

How does the system operate with 35% wind and solar?
Mid-July Mid-April
Mid-April shows the challenges of operating the grid with 35% wind and solar. This was the worst week of the 3 years studied.

Operations during mid-April
No Wind/Solar 35% Wind/Solar
