Do I need additional power if I have an existing electricity connection?
If you’re working at a large commercial property or business which has an existing electricity connection (over 70kVA) and require additional power, we’re here to help guide you through the process. We highly recommend contacting an electrical contractor initially as they can help determine your power requirements.
Can a main electrical substation be upgraded without impacting operations?
A main electrical substation is a major component in an infrastructure portfolio and facility managers often face the problem of how to upgrade end-of-life equipment, without impacting operations. Sunnybrook Health Sciences Centre (Sunnybrook) faced these challenges when it undertook a project to upgrade its main outdoor electrical substation.
Why was a substation upgrade prioritized?
“To ensure our substation would meet future campus needs, a project that completely upgraded the existing installation was prioritized.” Given the large capital expenditure associated with building a new substation, an analysis of project goals and constraints was performed. Project Design Goals Included:
Can I change my connection agreement if my capacity decreases?
For decreases in capacity, we will agree to revise any connection agreement you have with us. We are able to facilitate changes from the 1st day of the month following your notification of the change, provided you promptly sign and return the amended agreement.
What if a change in equipment affects the electrical characteristics of my site?
We would recommend you contact us regarding any change in equipment that could impact upon the electrical characteristics of your site. The details of changes and details of equipment installed or removed can then be determined.
How is incoming utility service distributed?
From here, the incoming utility service is distributed within the campus either at the service voltage or at a lower voltage, through the use of step-down transformers.
