Abstract: A technique of managing electrical power sharing between consumers connected to a local power grid by determining for each consumer, the amount of electrical power stored in a power storage and the amount of electrical power required for consumption; receiving a retail tariff and an export tariff for electrical power; calculating a total power consumption tariff, based on the total stored and required amount of electrical power; calculating a power sharing tariff based on the received retail tariff, the export tariff, and the total power consumption tariff. Also, determining a consumer to share electrical power based on the calculated power sharing tariff; and allocating energy resources between the consumer and a power storage to maintain balance within the local power grid. Calculation of the power sharing tariff is based on maintaining the total power consumption tariff such that a portion of the electrical power is maintained within the local power grid.
