Iowa's SOO Line Could Bolster Renewable-Sourced Transmission

September 29, 2025--Researched by Industrial Info Resources (Sugar Land, Texas)--The U.S. Midwest could see a new avenue open for the transmission of renewable energy, despite a significant drop in support for a similar project earlier this year. The SOO Green Link Project is designed to carry up to 2.1 gigawatts (GW) of electricity sourced from wind and solar facilities in Iowa about 350 miles to north-central Illinois. Last week, its developers signed a final municipal franchise agreement in Iowa, where the bulk of construction will take place. Industrial Info is tracking about $4 billion worth of projects within the SOO development, as well as more than $9 billion worth of active and proposed renewable-energy projects in Iowa. The SOO project is being developed by energyRe and Copenhagen Infrastructure Partners.
