For example, if a customer pays for electricity on a time of use plan from their power company, a lighting device that stores energy when the electricity rates are low and uses the stored energy when the electricity rates are high may save money on their electric bill by using that stored power intelligently.  In a similar example, a customer can reduce the amount of power it consumes from the power company by using a local power source to power a lighting device helping the power company deal with periods of time when there is a peak in energy consumption that puts a strain on their ability to supply power.

A single lighting device may not make an impact in shedding power however when scaled up such that many devices can be installed in an area to create a highly distributed energy storage system, the grid-shifting lighting device can have an impact in reducing demand through peaks in power usage.  Demand response and peak shedding applications are popular to reduce load on an oversubscribed electrical grid.
