The new peak isn't hours, it's days. We're built for that.
Clean, compact multi-day electricity storage at the cost of gas. Built for the new peak.
A multi-day peaking event is when demand spikes — and then plateaus — for days.
Everyone talks about rising demand. The harder problem is what happens when it spikes and then stays high for days, not hours. A heat dome parks over a region for four days. An arctic blast creates competing heating and electricity demand. These events push prices to exceptionally high levels, which hurts businesses and customers. The tools built for the old peak were never designed for this one, and thousands of them are aging out right when we need them most.

The next generation of peak power.
Fourth Power covers the peak the way a gas peaker does, except nothing is combusted. The system converts low-cost electricity to heat, is capable of storing it for weeks, and returns it as electricity on demand.

Utilities and Power Producers
Reliable power for multi-day peaking events.
Peaker-class storage sized for the one-to-three-day events that keep getting more common — lower lifetime cost than new gas, on a single acre, with no air-quality review standing between you and a built project.
Data Centers & Large Loads
Flexible power for faster interconnection.
The wait to get connected is measured in years. Pair your load with flexible multi-day storage in order to lower your peak impact on the grid and interconnect faster.
