Why a GridGenius variable speed generator
Burn a lot less fuel
Variable speed operation improves efficiency at all loads by up to 50%. Fuel savings run 20–50% depending on the application and time of year.
Run low loads without worry
The VSG runs continuously at low loads with high efficiency and no added maintenance risk. You no longer need several different sized gensets.
Simpler powerhouse
One GridGenius VSG can replace 2–3 fixed speed gensets. That means fewer spare parts, less training, and lower maintenance and logistics costs.
Utility-grade power quality
Power quality meets the highest specifications in every application. Clean power lowers consumption and extends the life of your equipment.
Ready for solar and wind
Add renewables later without curtailment. GridGenius supports up to 90+% renewable penetration for the lowest levelized cost of energy.
Watched around the clock
PowerView and FleetGenius software give you 24/7 remote monitoring, management and software upgrades, supported worldwide.
GridGenius VSG specifications
The GridGenius Variable Speed Generator decouples engine speed from electrical frequency control. The engine runs at the most efficient speed for the load at that moment, instead of being locked at a fixed speed. That is where the fuel efficiency comes from.
Every VSG is built around the GridGenius Energy Center with VSG software, so it can run islanded or grid-tied, grid-forming or grid-following. Multiple units parallel automatically as your load grows.
- Output: 250kW to 2.5MW in 250kW increments
- Fuels: diesel, biodiesel, natural gas, propane and biogas
- Qualified engine OEMs: Caterpillar, Cummins, MTU/Rolls Royce, Volvo Penta
- Up to 35% lower annual operating costs and emissions vs fixed speed gensets
- Up to 90+% renewable penetration without curtailment
- Islanded or grid-tied; grid-forming or grid-following
- Automatic paralleling between multiple GridGenius systems
- Also available as the Rapid Deployment Flex Microgrid, 250kW–2MW in a 40-foot mobile platform
Built on proven microgrid technology
“The team is excellent with extensive knowledge of energy and lowering costs. Have worked with Innovus for years and always found service to be very good.”
“Innovus Power has proven themselves as true professionals based on technical know how, unique advanced technology, and genuine customer service. Contrary to what Eugene XO posted, I personally saw Innovus go to great lengths to satisfy a customer who experienced a delay caused by supply chain issues (no fault of Innovus). Their technology is truly unique and allows microgrids to operate at greater efficiency and with more renewable (solar or wind) capacity then would otherwise be possible. I highly recommend Innovus Power.”

Frequently asked questions
How much does a variable speed generator cost?
Pricing is quoted on request. Cost depends on output, fuel type, engine OEM, enclosure and whether you add storage or renewables. Send us your load details and we will price it.
How much fuel will I actually save?
Fuel savings run 20–50% compared with fixed speed gensets, depending on the application and time of year. With renewables added, fuel use can fall by up to 80%. Our modeling tools estimate savings for your specific load.
What sizes and fuels are available?
250kW to 2.5MW in 250kW increments. Fuels include diesel, biodiesel, natural gas, propane and biogas. Qualified engine OEMs are Caterpillar, Cummins, MTU/Rolls Royce and Volvo Penta.
Can it replace my existing fixed speed gensets?
Yes. One GridGenius VSG running 24/7 can replace 2–3 fixed speed gensets, which simplifies the powerhouse and cuts maintenance, training and spare parts costs.
Do you ship outside the United States?
Yes. Innovus Power serves the USA, Canada, the Caribbean, remote Arctic locations and worldwide projects, with 24/7 remote monitoring and support.
Do you rent generators?
No. GridGenius systems are sold for purchase only. Project financing is available through our development partners. The Rapid Deployment Flex Microgrid can be deployed in timeframes similar to rental gensets.
