Modernizing the Power Grid to Transform Cities

We're going underground

More than 20% of our electric lines are now underground rather than overhead. We plan to install most of our new electric lines underground as well as those that need replacement or upgrade. The cost of “undergrounding” has come down significantly. When considering the full life cycle cost of burying lines versus putting them overhead, the cost is about the same.

Underground wiring is five times more reliable.

• Fewer outages
• Increased performance
• Safer for people and wildlife
• No tree trimming costs
• More visibly appealing

Burying lines transforms an alley

Alliant Energy cooperated with a group in Marion, Iowa, that worked to transform an alleyway. Through removing the overhead power lines and putting them underground, the area became a usable and attractive public gathering space that showcases local artwork.
