The price of a diesel generator is often the first question, and the hardest to find online. At Solution NRJ, our prices are posted. Here is what you need to know to set your budget in 2026.

Prices by power rating

Prices in Canadian dollars, before taxes, for our enclosed Perkins diesel generators with a sound-attenuated enclosure:

The Perkins 200 kW is $59,000; the 25, 300 and 400 kW models are available on request. We also offer a Kubota 40 kW generator at $28,000 with an enclosure or $26,000 as an open unit. All our diesel generator prices.

The bigger the unit, the cheaper each kW

The price does not double when the power doubles. A 10 kW works out to about $1,250 per kW, a 100 kW to about $440 per kW. If you are hesitating between two sizes, the larger one often costs little more and leaves room to add equipment later.

A new Perkins 20 kW costs $21,000 before taxes; what it includes and why some ads are cheaper: see the price of a 20 kW diesel generator.

What changes the price

  • Power rating: the main factor (see the table).
  • Enclosure: an open model, without a sound-attenuated enclosure, costs less. It always comes with a 200 L tank.
  • Voltage: the same model costs the same in 120/240 V, 120/208 V or 600 V.
  • Options: more advanced controller, larger tank, and so on.

What is included

  • Perkins diesel engine and genuine Stamford alternator.
  • Deep Sea DSE6120 controller.
  • Block heater, glow plugs and smart battery charger.
  • Full preparation: oil and Prestone antifreeze.
  • 1-year or 1,500-hour warranty, whichever comes first.
  • CSA and EPA certifications.

Other costs to plan for

The generator price is not the total project cost. Depending on your installation, plan for:

  • The transfer switch, sold separately: it moves the building onto the generator (see our article on automatic transfer switches).
  • Transport to your site.
  • Installation: concrete or gravel base, electrical connection by a master electrician, permits where required.

These costs depend on distance, access and your electrical panel: we assess them with you in the quote.

What about taxes?

In Quebec, add GST (5%) and QST (9.975%). Example for the Perkins 40 kW:

  • Price: $29,000.00
  • GST: $1,450.00
  • QST: $2,892.75
  • Total: $33,342.75

A 30% deposit on the total is required with the order.
