The City of Medicine Hat needed to design a replacement for the aging infrastructure in a 69 kV generation substation

They hired Spark Power’s engineering services and expertise, and we completed the project in approximately 12 months and significantly helped to enhance the City of Medicine Hat’s operating system by creating a safer and more efficient environment.

• Engineered a package that allowed for the replacement of breakers, current transformers (CTs), potential transformers (PTs), and disconnect switches while maintaining operation in the substation.
• Upgraded substation protection to the current series.
• Created a design with minimal impacts to operations and almost zero downtime.
• Completed a site survey and added documentation for existing line structures that were previously undocumented.

• 69 kV generation substation modernized in approximately 12 months.Breakers, CTs, PTs, and disconnect switches replaced and protection upgraded to current series.
• Operations maintained throughout the project. Phased approach kept the substation running with almost zero downtime.
• Existing assets fully documented. Site survey captured undocumented line structures so the City has accurate as-builts going forward.
• Safer, more efficient operating environment. Upgraded protection and replaced equipment reduced arc-flash exposure and improved reliability.
