Power grids frequently produce excess
     Energy that is wasted during non-peak
          Times of day (or week, month, or year).
               Especially with intermittent renewable
                    Energy production, there can be a lot
                         Of waste, with limited options for use
                              Therefore
                         We need users of energy who do use
                     The excess energy when produced,
                Yet remain able to shut down quickly
           When the energy is required for users
     During peak energy consumption times.
