The document discusses International Energy Resources' IER Energy Saver device, which aims to optimize power factor and reduce energy costs for customers. It does this by precisely determining the capacitance needed for each inductive load and storing reactive power, allowing motors to function more efficiently. This can result in immediate power savings of up to 25% and pay for itself within 2 years. By improving efficiency and increasing capacity, the IER Energy Saver also benefits utilities by reducing fossil fuel usage and expanding the capacity of electrical systems.
