From challenge to

completed project

AltaLink’s Duchess Substation needed modern protection, monitoring, and communications to support new connections to the grid. Spark Power upgraded the station’s high-voltage and P&C systems and added the supporting telecom infrastructure.

How we

solved it

  • Comprehensive substation upgrade to support system reliability and DER integration
  • Replacement and installation of 138kV high-voltage switching and protection equipment
  • Upgrades to protection and control systems including full commissioning
  • SCADA system enhancements for improved monitoring and control
  • Telecom system installation in a new building to support DER customer connectivity

The metrics

that matter

  • Improved substation reliability and system performance. New 138kV switching and protection equipment delivers measurable reliability improvements across the station.
  • Enhanced protection, monitoring, and remote control. Upgraded protection and control improve visibility and response capability.
  • DER integration enabled through modernized telecom infrastructure. New telecom building and systems provide the connectivity required for distributed energy resource customers.
  • Full protection and control system commissioned. All systems tested and verified to AltaLink specifications before handover.
