By delivering low-cost electricity to consumers, SOO Green will help protect ratepayers from rising energy costs driven by growing demand.
The SOO Green project will unlock billions in social benefits, including a reduction in harmful air pollutants and associated improvements in health. It will also help accelerate economic growth by providing energy for growing sectors like data centers and AI.
SOO Green HVDC Link is a proposed 350-mile underground transmission line from Central Iowa to Western Illinois that would enable the delivery of 2,100 MW of reliable energy and connect two of the nation’s largest power markets (MISO and PJM). SOO Green will increase the capacity of the electric grid and deliver billions in benefits.
Installed underground along existing rail corridors, SOO Green offers an innovative model to deliver abundant energy to help Illinois create good-paying union jobs and produce billions in ratepayer savings.
