Scenarios• “In-area”
– Each transmission area meets 35% of its load from wind and solar sites in that area
• “Mega projects”– Each transmission area meets 35% of its load from wind and solar sites that have the
least cost of delivered energy
• “Local priority”– Similar to Mega projects but with small bonus given to in-area sites
• “High solar”– Similar to Mega projects or Local priority but with ~10% solar penetration
• “High capacity value”– Each transmission area meets 35% of its load from wind and solar sites that are best
correlated with load -have highest capacity value
• “High geographic diversity”– Each transmission area meets 35% of its load from wind and solar sites that are
geographically diverse

Preliminary Analysis
(being revised)
Study area wind penetration by capacity is 137% of min load and 49% of max load
The highest penetration rates are in Southern Nevada with wind as 217% of min load and in Northern Nevada with wind as 66% of max load

April 2006 (being revised)
Net load (load minus wind minus solar) is highly variable with some negative net load for a few hours this month

Tasks and Schedule• Stakeholder Meeting (5/23/07)• Data Collection (second half ‘07)
– Wind and solar mesoscale modeling (3TIER, SUNY, NREL)– Utility load, generator, transmission data (Exeter)
• Preliminary Analysis (first half ‘08) - GE – Extensive statistical analysis with various options for wind/solar sites and
transmission• Scenario Development (8/08) - GE
– In-state vs out-of-state resources– Geographically diverse resources– Mega projects– Best correlated with load
• Stakeholder Meeting (8/14/08)• Revise statistical analysis and scenarios with new wind data• Run Scenarios (start Jan ‘09) - GE
– Examine costs due to regulation, load following, unit commitment– “Dives” to investigate issues such as Hoover– Examine mitigation strategies/options– Determine contributions to reliability and capacity value
• Stakeholder Meeting – Preliminary Results (Apr/May ‘09)• Stakeholder Meeting and Final Report (Sep/Oct ‘09)
