MISO Fast Facts• Non-profit organization• Voluntary membership• Regulated by the Federal Energy Regulatory
Commission (FERC)• $41 billion energy market • 1,896 pricing nodes• Governed by independent eight member board• About 750 employees• Main office in Indianapolis, branch office in St. Paul.

Transmission – the Great Enabler
• Like an interstate highway system, transmission can enable access to lower cost electricity
• New transmission generally reduces wholesale prices by reducing congestion, improving access to lower cost energy. In aggregate, net benefits increase, but it can create winners and losers
• There are other benefits beyond lower production costs
• See simplified example on next slide

Apples and electricity *• Imagine 2 valleys, separated by a mountain range. The
apples on the west side cost $5/bushel, while the apples on the east side cost $10/bushel.
• A new highway goes through the mountain, allowing people on the east to buy western apples. The new market price of apples for everyone is $7.
• Western growers and eastern consumers are happy. Western consumers and eastern producers, not so much.
• Now substitute the word electricity for apples, and transmission for highway.
* At this point please refer to disclaimer on slide 3

Costs and Benefits• Of course building that highway or
transmission lines is not free• If you spend $50 million dollars to build a
transmission line that isn’t needed, you don’t produce net benefits, only costs
• MISO engineers conduct detailed studies of transmission costs and benefits in order to justify whether a line should be built, and optimize location, size, etc

Current Events
• Integrating renewables into the Grid– Transmission expansion– Integration challenges
• Cost Allocation (who pays)• Generator retirements (EPA, cheap natural
gas, aging plants) and its effect on reliability and prices
![Page 15: Citizens League Electrical Energy: Affordability and Competitive Pricing Working Team Electric Transmission.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649cec5503460f949b8816/html5/thumbnails/15.jpg)
Transmission Expansion to Integrate Renewable Energy
• Most states in the MISO footprint have Renewable Portfolio Standards (RPS’s) requiring a certain percentage of renewable energy
• MISO conducted 2 major studies to determine the amount of transmission needed to meet RPS’s.– Regional Generation Outlet Study (RGOS) – Regional
15 year plan to meet state RPS’s - $15 to $20 billion.– Candidate MVP Study - $5 billion. An in progress,
more detailed plan to justify the first phase of new transmission projects to meet RPS standards - $5 billion.

Candidate MVP Study
![Page 18: Citizens League Electrical Energy: Affordability and Competitive Pricing Working Team Electric Transmission.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649cec5503460f949b8816/html5/thumbnails/18.jpg)
Integrating Renewables
• Renewable Energy Sources (wind, solar) are variable or intermittent
• To integrate renewables:– Dispatchable Intermittent Resource (DIR)– Improved Forecasting– Benefits of Scale to Smooth Level of Variation– Energy Storage– Manitoba Hydro
![Page 19: Citizens League Electrical Energy: Affordability and Competitive Pricing Working Team Electric Transmission.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649cec5503460f949b8816/html5/thumbnails/19.jpg)
Cost Allocation
• How to pay for regional transmission?• Traditionally local area paid for local
transmission, or shared with immediate neighbor• Hard to make traditional model work for long-
distance renewable generation• In response, MISO developed the concept of
regional Multi-Value Projects (MVP’s)• Costs of MVP’s shared across entire MISO
footprint

MISO studies more than just transmission
• As Reliability Coordinator, MISO helps ensure the region has adequate supply of electricity
• For example, recently, MISO conducted an EPA Regulation Study to determine potential level of generator retirements likely under different EPA regulatory scenarios
• Summary – New Federal EPA Regulations will not have a dramatic impact on MISO supply, reliability, or prices
