A method and system for controlling voltage and reactive power for electrical grids includes monitoring the output of the energy generation facilities at the point of interconnection (POI) of each energy generation facility to the power transmission system of the electrical grid. In addition, the voltage at a point of utilization (POU) is monitored to determine when the output voltage of the energy generation facilities must be adjusted to maintain voltage at the POU. In addition, when it is determined that energy generation facilities are exchanging reactive power, the voltage set points of the energy generation facilities are adjusted to reduce the exchanged power.

The invention involves an energy monitoring and control system that monitors and controls the peak energy demand so that demand charges are reduced. The system includes an electrical load which receives an aggregate power signal having grid, battery, and solar power supply components. An energy monitoring panel determines the grid and solar power components. A battery-demand modulator panel determines a charge cycle for a battery power supply. An energy gateway processor receives information from the battery-demand modulator panel regarding the charge cycle for the battery power supply and information from the energy monitoring panel regarding the grid and solar power components. The battery-demand modulator panel modulates the charge cycle for the battery power supply, in response to a signal from the energy gateway processor, to adjust the battery power supply component of the aggregate power signal.
