Industrial voltage drop and peak shaving

Protect equipment, flatten the load profile, and lower the monthly demand charge with one piece of equipment behind the meter.

What this looks like in practice

Industrial sites with large motors, pumps, presses, and compressors need voltage support or brief moments of very high power. Those peaks set the demand charge the site pays every month and accelerate wear on every machine they spike through.

A flywheel sits between the grid and the load, protecting equipment and saving on maintenance, materials, and downtime. It also smooths the peaks when they come. The grid sees a flatter load profile, the monthly demand charge drops, and the equipment lives longer.

One hour of an industrial load profile

The peaks the equipment creates are what set the demand charge. A flywheel takes them out before they reach the meter.

Indicative one-hour load profile of an industrial site with multiple presses or pumps cycling. Demand charges in most European tariffs are billed on the highest 15-minute average during the billing period; cutting the peaks the meter sees lowers the bill directly. Exact savings depend on tariff structure, site load shape, and flywheel sizing.

Three jobs in parallel, one piece of equipment

A Teraloop flywheel runs all three modes automatically. Voltage support always wins if the others are active. The operator sees one piece of equipment and one HMI.

1

Voltage support

When grid voltage drops, the flywheel injects reactive current into the bus within 10 milliseconds to hold the voltage above the trip threshold of critical motors. Highest-priority mode.

2

Peak shaving

When a press or motor draws a brief spike, the flywheel covers it from stored energy. The meter sees a flatter profile, and the monthly demand charge drops.

3

Load shifting

Stores excess on-site solar or co-generated energy and releases it when demand is high, reducing purchases from the grid during peak tariff hours.

Why a flywheel here

Sub-10 ms voltage support

Holds the voltage above the trip threshold of critical motors and pumps before damage starts.

Made for daily cycling

Industrial peaks happen hundreds of times a day. Millions of cycles with no capacity fade. No replacement cycle inside a 25-year operating life.

Behind the meter, low maintenance

Containerised, plug-and-play, no flammable chemistry on the production floor. Minimal maintenance and no consumables.
