Zusammenfassung:	Systems and methods for storing power from distributed generation systems or other loads and sources that affect line voltage are disclosed. In embodiments, a water heater can be powered in a way that absorbs excess power from the grid by heating water when a controller senses excess power generation in the grid. Excess power generation can be sensed by either an increase in line voltage amplitude above a predetermined standard, or an increase in line voltage frequency above a predetermined standard.
