Torus Scales Hybrid Storage Output 76% in Utah
Utilities and grid developers buying hybrid flywheel-battery storage should watch whether rising factory output brings more standardized, lower-cost supply.

Should the U.S. expand large-scale battery and flywheel energy storage on the grid?
Torus says company-wide production rose more than 76% after its GigaOne factory in Salt Lake City came online about six months ago. The 545,000 square foot plant builds equipment for the Torus Station, a hybrid system pairing a flywheel with a lithium iron phosphate battery, and operators in energy storage should note the company's expanding manufacturing footprint.
Why it matters
Hybrid storage pairs a fast-responding flywheel with a longer-duration battery, a configuration that targets grid services like frequency support and peak management. The factory expansion matters because it signals a shift from one-off projects toward standardized, higher-volume production of storage equipment.
Torus reports a 76% company-wide production increase and a workforce growth from 88 to almost 300 employees since early 2025, but the company has not released unit counts or MW/MWh output for the period. Its 545,000 square foot GigaOne plant is roughly 14 times the size of its 37,000 square foot South Salt Lake facility.
The players
Torus
Torus is an energy storage company that builds hybrid flywheel and lithium-ion battery systems for grid and utility applications, operating manufacturing plants in Salt Lake City and South Salt Lake, Utah.
BEST
BEST is an energy storage publication that reported in 2020 on a hybrid lithium-ion and flywheel project in the Netherlands.
The details
The flywheel handles short, high-power events within milliseconds, while the lithium iron phosphate battery supplies sustained energy over longer periods. Energy is held mechanically in a rotor inside a vacuum-sealed steel enclosure installed below ground. Routing rapid load changes to the flywheel reduces high-power cycling on the battery cells, which the company says may lower degradation and how often the battery must be replaced.
Timeline
Approximately six months before this report, GigaOne came online and production increased.
In 2020, BEST reported on an 8.8MW Netherlands project combining 7.12MWh of lithium-ion storage with 3MW of flywheels.
At the beginning of 2025, Torus had 88 employees.
Market Landscape
Torus's hybrid Torus Station pairs its Spin flywheel, rated 10C with a six-minute full discharge and a claimed 25,000-cycle life, with its Pulse battery, rated 0.5C with a claimed 7,500-cycle life. The company's 2020 Netherlands project with BEST, an 8.8MW combination of lithium-ion and flywheel storage, shows the same hybrid approach deployed in the field earlier.
Operators in energy storage procurement should expect a growing number of hybrid flywheel and battery offerings as manufacturers scale up output. Utilities and project developers evaluating grid-services equipment should review cycle-life and degradation claims against independent testing before relying on them in procurement.
The takeaway
The expansion points to hybrid storage moving toward standardized, higher-volume manufacturing. Buyers should request independent cycle-life data and track whether Torus publishes unit output figures in future reporting.
