Wind power might require a costly grid expansion (JSOnline.com)

The Midwest could be crisscrossed with a new network of high voltage power lines to move wind-generated power from the windiest spots in the Dakotas, Iowa and Minnesota.
A group of utilities in 11 states, including Pewaukee-based American Transmission Co., is studying three alternatives, each of which would cost at least $23 billion over the next 20 years.
What's unclear: How much it will end up costing for Wisconsin's share of the projects. A more detailed analysis has been launched to help determine what the payoff could be in savings from increasing the flow of low-cost power around the region.
