Torus Reserve is hybrid energy storage that pairs a millisecond-response flywheel for sudden sags and spikes with a chemical battery for sustained capacity. Utilities use our systems as flexible assets, dispatching them during peaks to maintain service and reliability for communities.
Reliable power for your community
Torus Reserve stabilizes the grid, integrates renewable energy, and makes existing infrastructure more efficient. This helps communities keep growing without putting upward pressure on electricity rates.
Less pressure on your utility bills
The typical alternative to a Torus system is a peaker plant that fires up when lines are congested or demand is high, which is costly and high in CO2. Instead, Torus stores power ahead of time, including renewables that would otherwise be curtailed, and discharges it when needed. Fewer peaker plants running and being built often translates to lower costs for everyone.
Faster path to reliable power
As load grows and shifts, utilities need capacity they can deploy fast enough to keep pace with demand. Adding Torus systems near load is a quick, easy way to keep the grid reliable and expand what it can power. Because it's faster and more cost-effective, utilities can bring capacity online without a long wait, so communities get reliable power sooner.
Firming renewables
When renewable generation outpaces demand, it can be curtailed. Torus Reserve absorbs the excess and discharges it during congestion to serve load, adding capacity for nearby homes and businesses.
Rocky Mountain Power
Rocky Mountain Power calls on Torus systems at commercial and industrial sites across its territory through its Wattsmart Battery Program. In 2025, that meant 359 demand response events. These assets provide support when the grid needs it most, improving resilience for communities.
