UPS or generator
A UPS gives short-term power from batteries and conditions the supply. It keeps computers and network gear running through a brief outage and allows orderly shutdown. A generator provides longer-term power but takes seconds to start.
Many sites use both: a UPS to bridge the gap and a generator for extended outages.
Sizing matters. A unit that is too small trips under load, and one that is too large wastes fuel and money.
Decide what to protect
List critical loads such as refrigeration, life safety systems, medical equipment, servers, security and some lighting. Backing up everything is rarely needed and costs more.
A separate emergency panel for critical circuits keeps the system manageable.
Physical and code needs
Generators need an outdoor or ventilated location, fuel supply, exhaust routing, noise consideration and a transfer switch. Batteries need space, cooling and sometimes fire-rated enclosures.
Permits and landlord approvals may be required.
Natural gas, diesel and propane each have storage, supply and permit differences, so choose the fuel with the site in mind.
Coordination of trades
Our electrical and mechanical crews work together on the generator pad, exhaust, fuel lines and ventilation. A single team avoids finger-pointing between trades.
We also commission the transfer switch and test under load.
Maintain it
Backup systems fail when neglected. Run scheduled tests, replace batteries on time, and keep fuel fresh. Winter operation needs particular attention in Alberta, including block heaters and cold-weather fuel.
Keep a short written procedure for what staff should do when an outage occurs, and who to call. We answer calls 24/7/365.
Questions we hear
Does a generator need a permit?
Generally yes, for the electrical and gas or fuel work. Your landlord may need to approve it too.
Can a UPS run a whole office?
Usually only critical equipment. Whole-site battery systems exist but are far larger and costlier.
