High Temperature Superconductor—TSS114 Northwest Substation

• Superconducting Bus Tie: Operating at 12kV and 3000 amps, the HTS system functions as a bus tie between two terminals, enabling an N-2 contingency configuration that significantly boosts system redundancy.
• Liquid Nitrogen Cooling: The system uses liquid nitrogen to maintain superconductivity, allowing for high-capacity power transfer with minimal energy loss.
• Strategic Location: The Northwest Substation was selected for its similarity to the Chicago Business District environment, making it an ideal testbed for urban grid applications.
