Abstract

A modification method and system. The method includes detecting and monitoring by a computing system, a frequency signal associated with an input voltage signal used for powering a plurality of power consumption devices at a specified location. The computing system compares the frequency signal to a predetermined frequency value. The computing system determines that the frequency signal comprises a first value that is not equal to the predetermined frequency value. The computing system calculates a difference value between the first value and the predetermined frequency value. The computing system compares the difference value to a second value. The computing system enables a load adjustment modification process associated with the plurality of power consumption devices. The computing system generates and stores a report associated with the load adjustment modification process.
