If you use 250kw for only one hour during one week of one month, your monthly demand charge will be based on the capacity required to deliver 250kw of electricity throughout the entire month, even though you may often be using significantly less power during the rest of the month.
Thanks to Arista’s Power on Demand system, commercial electricity users can level the power demand on the grid and lower (“shave”) the peak demand spikes that create these costly demand charges. Power on demand is designed to generate energy from wind turbines and/or solar arrays and to also store energy from the grid itself when energy costs are low. Our real-time, dynamic monitoring system then releases stored power for use during peak demand periods so that peaks in power demand are drawn from the PoD storage system rather than the grid. Stored energy is released only when electricity charges would be highest. The monitoring system continuously maintains power demand from the grid within optimal levels that also prolong battery life.
The result is lower “peak” demand on the grid, reduced demand and consumption charges, a dramatic savings on electricity costs and a Return on Investment (“payback period”) that no stand-alone renewable energy system can match.
In fact, while most stand-alone renewable energy systems have a payback period of 15 to 20 years or more, our Power on Demand system can provide a payback period as short as 2 to 6 years.
