Save on Your electricity cost during peak times

Use Fortress Power Batteries to store energy when electricity rates are cheapest,
and discharge during peak usage periods.

Reduce Peak Charges

If your utility charges Time-of-Use (TOU) rate, you may be paying 2-3 times more for the electricity that you consume during the peak hours.

Time of use rates are a kind of electricity billing arrangement in which the price of electricity changes based on the time of day.  They make electricity more expensive during “peak hours,” when there is high demand, and less expensive during hours of low demand.

You can avoid the high peak charges by storing the energy from the solar panels or from the grid when electricity rates are cheapest, and discharging the battery power during peak usage periods.
