Background on Wind on the Wires
• Non-profit Advocacy Organization launched in 2001 to overcome the
barriers to bringing wind energy to market in the Midwest.
• Members include non-profit environmental organizations, tribal
representatives, farm groups, wind developers and manufacturers,
American Wind Energy Association, businesses that provide goods and
services to the wind industry.
• Work in 3 areas:
– Technical – work with electric utilities and Midwest Independent
System Operator (MISO – regional “grid” operator) on transmission
planning for wind, market and operational rules that treat wind fairly
– Regulatory – actively participate in cases where states are approving
new transmission lines that will deliver wind energy
– Policy education/outreach/advocacy – work with governors, state
regulators, legislators, local elected officials, regional groups, colleague
organizations, general public on wind and transmission issues
• Support – Foundation grants and member contributions

MISO existing wind:
~8,000 MW
MISO State RESs:
~25,000 MW
MISO-wide 20% wind: ~50,000 MW
MGA 30% by 2030: 75-100,000 MW

On-Going Challenges for Wind Power and Transmission
• Transmission planning process needs to properly accommodate
public policy goals and move timely through the regulatory process
• Cost allocation – how to pay for new transmission. Cost for large,
regionally beneficial transmission facilities needs to be broadly
allocated
• Fair Market and operational “rules of the road” – must realize and
recognize unique characteristics of variable resources like wind
power
• Wind Integration issues – these issues show up in transmission
planning, the energy market and operations
• Siting/routing new transmission lines
Transmission to Support a Clean Energy Future
• Transmission Expansion
CapX 2020 Initiative
MISO Regional Generation Outlet Study (RGOS)
MISO Candidate Multi-Value Projects (MVP)
CapX 2020 Initiative
• CapX 2020 Initiative undertaken by Minnesota utilities
• Transmission planning done for a number of “future” scenarios out to 2020
– Minnesota generation build out
– Generation from west (North and South Dakota)
– Generation from east markets
• Lines moved forward that were common to all futures
• 3 345 kV lines – Fargo-St. Cloud, Brookings to Twin Cities, SE MN line
• Regulatory proceedings:
– Certificate of Need, including Environmental Report
– Siting/Routing
• All lines have received CON; 2 lines have received Site/Route permit;
currently in Siting/Routing for SE MN line
• Segments will be placed into service between 2013-2015
Regional Generation Outlet Study (RGOS)
•
Developed transmission portfolios needed to implement Renewable
Portfolio Standards or goals at the least cost for consumers while
continuing to reliably serve load.
•
RGOS summary:
– Renewable energy: ~ 40 GW of total wind (~28.5 GW new & ~11 GW ‘existing’)
– Iterative development of transmission plans; options include 345 kV, 765 kV, and
HVDC; analysis included power flow, production cost models (PROMOD), and
business case / value metrics
– The three transmission overlay plans represent potential investment of $16B to
$22B (2010 dollars) over the next 20 years and consist of new transmission
mileage of 6,400 miles to 8,000 miles
– RGOS identified a set of Starter Projects considered viable for near term
development; The estimated cost for this starter set is approximately $5.8 Billion
(2010 dollars), $4.4 billion of which is within the Midwest ISO borders
