Standby, prime and event power for buildings, industrial parks and job sites from Airdrie to Okotoks. Every package is prepared and proven on a load bank in our Red Deer yard, then trucked south with the transfer switch, cable and distribution it needs.
These cards come from the live inventory, so they show only what is free to rent right now. Check the voltage on each one against your service before you call — in Calgary it is often the detail that picks the unit.





















Calgary's temporary-power work is less about wellsites than the rest of the province. It is mostly buildings that cannot go dark, industrial parks ringing the city, and a construction market that keeps going through chinooks and cold snaps alike.
Server halls, telecom rooms and labs that already have a standby generator — until it is down for service, failed a test, or is being replaced. A rental with a transfer switch covers the gap so the permanent unit can be worked on properly.
Downtown and Beltline buildings taking a planned outage for switchgear or a service upgrade. The set is sized to what must stay on — elevators, life safety, tenants' critical circuits — rather than to the whole building.
Foothills, Shepard, Balzac and the east-side logistics parks, where a warehouse or shop needs power ahead of its permanent service, or through an outage it cannot afford to wait out.
New communities going up on every edge of the city need site power long before the utility energises the lots — trailers and tools in spring, and temporary heat for hoarding once the weather turns.
Rural properties west and south of the city, from Bragg Creek to Foothills County, where three-phase service is scarce and a shop, barn or pump needs more than a portable from the hardware store.
Calgary's summer is one event after another, most of them in parks and grounds with no power where the stage goes. Sound-attenuated sets and distribution sized for stages, vendors and lighting.
NexSource Power's Calgary office is on 4 Avenue SW, downtown. The generators are not parked there: the rental fleet is prepared in the Red Deer yard, about 150 kilometres north, where the NPI Series gas packages are also built.
That arrangement is deliberate. A unit leaving for a Calgary site has been fuelled, set to the voltage the site needs and run against a load bank before it is loaded on the truck — so the first time it carries real load is not on your commissioning day.
Field service answers 24/7, every day of the year. If a set faults on a Calgary site overnight, the call reaches people who know the unit rather than a dispatcher reading from a manual.

The city and the communities around it where Calgary-area rentals most often go. It is not a boundary — the same fleet goes anywhere in the province and beyond.
No. The Calgary office is downtown on 4 Avenue SW; the generators are prepared, fuelled and load tested in the Red Deer yard and delivered from there. For a planned job that makes no practical difference, because the unit arrives ready to connect. For an emergency, call (403) 887-4567 and ask what can reach the site and when.
Yes, and it is one of the most common Calgary requests. A rental set connects through a transfer switch, carries the critical load while the permanent unit is repaired, tested or replaced, and leaves once it is back. Send the building's load and the size of the existing generator.
Many Calgary commercial buildings run on 120/208 V, while industrial services are often 347/600 V or 480 V. Check the nameplate on the main switchgear or ask your electrician before requesting a quote. Matching the unit to the voltage is far cheaper than bringing a transformer to site later.
Yes. Tell us what is plugging in — the stage, the lighting rig, food trucks, washroom trailers — and how long the event runs. Sound-attenuated packages are the usual choice near an audience, with distribution laid out to the vendor rows so nobody is running extension cords across the grounds.
NexSource Power holds COR and ISNetworld registration. Many Calgary general contractors, facility managers and industrial owners ask for one or both before a supplier works on site, so mention it if your project requires them.
On many units, yes. Rent-to-own covers the NPI Series and parts of the wider fleet, with rental payments put toward buying the unit — useful for a Calgary site whose temporary power is starting to look permanent. Ask which units qualify when you request a quote.
Tell us what has to stay on, the voltage, the address and the dates. You will get a written quote for the unit, the transfer switch or distribution, and delivery from Red Deer — and sizing advice is free.
