Peak load reduction.
No money down.

Tumalow uses energy storage to reduce the peak load at commercial/industrial facilities.  Pay only 60% of the actual savings you see on your bill; nothing for the hardware, installation, or the engineering studies.  

We can offer this by putting the battery to work for the smart grid while the it isn't working for you.  So not only are you saving money you are helping New York's grid stay reliable and efficient.  We can do all this without net metering or exporting power out of your building.

Energy storage providers: connect your devices to the Tumalow network to deliver maximum value to your customers.
