Rail Transmission Project Announced

Direct Connect Development Co. (DC DevCo) has announced the SOO Green Renewable Rail project, a proposed transmission line that would transport wind and solar energy underground from Mason City, Iowa, to the Chicago area in Plano, Ill.

SOO Green is a 2,100 MW, 525 kV high-voltage direct-current (HVDC) transmission line that would run underground along an existing railroad for 349 miles. The majority of the project’s route would be located along rail owned by Canadian Pacific.

SOO Green is designed to serve as a renewable energy hub by connecting two of the largest electric power markets in the U.S.: MISO and PJM. This would create a convenient location for a large number of renewable energy buyers and sellers to enter into standard transactions.

A high-voltage, direct current (HVDC) electric power transmission system uses direct current for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems.  For long-distance transmission, HVDC systems may be less expensive and suffer lower electrical losses.

HVDC allows power transmission between unsynchronized AC transmission systems. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power.
