• Wind is at the Bottom of the Generation Stack
• Due to High Off-Peak Wind, Cycling of Gas and Coal has Become More Common
– Leads to an Increase in Required Maintenance for Coal
• Nuclear Facilities in High Wind Areas Receive Lower Pricing Because of Inflexible Dispatch (eg. Duane Arnold)

Curtailment
• ISOs Can Curtail Wind Based on Reliability and Transmission Congestion
• All ISOs Have or Will Have a Penalty for Not Reacting to a Curtailment Request
• Wind generation is price sensitive, but will not voluntarily curtail until much lower than normal

• Limited Transmission Capability Near Existing Wind
• Wind Is Not Near Load Centers
• Increase In Congestion/Constraints Due to Installed Wind
• Transmission Needed to Meet State RPS Standards

Transmission Cost Allocation
• MISO Studied Needs for Transmission Portfolios to Meet State RPS Standards
• Cost of New Transmission Ranged from $16B-$22B
• Led to Candidate MVP Projects

Transmission Cost Allocation
• The Midwest ISO Filed Their New Cost Allocation Methodology on July 15, 2010
• FERC Approved Methodology in in December 2010
• Summary:– 100% Postage Stamp of Revenue to Load and Exports for MVPs– Unclear What Criteria Qualifies as MVP– Generation Interconnection is Unchanged– An Export Rate Will Be Developed to Eliminate Free Riders
Outside of MISO
• Generation Interconnection Costs Mostly Paid by the Interconnection Customer

• A result of the RGOS process• Predominantly 345 kV• Intended to interconnect RGOS zones to
existing infrastructure• Designed to be compatible with multiple
future transmission solutions• Included in MTEP 10 as possible suggestions
for addition and will be further analyzed in MTEP 11

• Dispatchable Intermittent Resources (DIRs)– Ability to Dispatch Wind Down
– MISO Filed with FERC
• Continued Growth In Wind– Tax Credits Last Until At Least 2012
– MISO Needs ~22,000 MW of Renewable Resources to Meet State RPS Needs (Does Not Include Exports)
• MISO Needs to Get Transmission Built– CapX2020 Is First Step
– Much More is Needed

• Continued Low Prices in Western MISO
– Particularly with Low Natural Gas Prices
• Limited Baseload Build in Western MISO
– Due to Economics
– Lmiited Transmission
• MISO Member Movement
– Do Not Want to Pay for Transmission
