SOO Green underground transmission line between MISO, PJM clears key hurdle with Iowa approval

Utility Dive, Sept. 18, 2023

The proposed SOO Green transmission line between the Midcontinent Independent System Operator and PJM Interconnection regions cleared a key hurdle when it was approved by Iowa regulators last week. The Iowa Utilities Board on Sept. 13 approved a petition by SOO Green HVDC Link ProjectCo, the project developer, for a franchise to build and operate the Iowa portion of the line. The 525-kV high voltage direct current line would run about 350 miles underground next to a railroad between Mason City, Iowa, and Yorkville, Illinois. Read more here.
