- Designed a 100MVA 138kV:25kV substation and 25kV distribution system to feed the client’s datacenter facility.
- Ensured that BC Hydro’s Technical Interconnection Requirements (TIR) were met and our team coordinated with BC Hydro throughout the project.
- Achieved less than 1% voltage drop during energization, removing any energizing restrictions and providing the client with maximum operational flexibility.
- Stage 1 of the substation was designed, constructed, and successfully commissioned and energized in 15 months.
- Stage 2 of the project was energized 4 months after the completion of stage 1.
Iris Energy contracted Primary to design a 100MVA 138kV:25kV substation and 25kV distribution system to feed their multi-building datacenter facility in Mackenzie, B.C. This included the design and integration of IPO circuit breaker architecture with a Point on Wave controller for each 50MVA transformer. These devices were deemed necessary to meet the utility voltage drop requirements during transformer energization inrush. We achieved less than a 1% voltage drop during energization, removing any energizing restrictions and providing the client with maximum operational flexibility.
Our team created the station design, equipment specifications and implementation of RTAC-based SCADA system to provide a communications backbone and SCADA interface for client operations. We also executed all applicable engineering studies such as load flow, protection, lightning, and grounding analysis.
Our design incorporated steel and wood structures to ensure long-term reliability while providing cost savings where possible. Stage 1 of the substation was successfully commissioned and energized in August 2022. Stage 2 of the system was energized in December 2022.
