Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power retail system which can achieve the equal quantity for equal duration duty more efficiently. SOLUTION: With this power retail system, a power retailer sends a power to a power user through transmission/distribution equipment 5 maintained and operated by the other power utility, and has supply and demand adjusting equipment 3. The supply and demand adjusting equipment has an energy storage apparatus 9, and a power reception/supply control apparatus 11 and can receive/supply a power from/to the transmission/distribution equipment. While a power larger than an estimated consumed power of the power user by a prescribed value is generated by power generating equipment 1, according to the relation between the generated power Wa and the power Wb actually consumed by the power user, if Wa>Wb, the excessive power is received from the transmission/distribution equipment and stored in the energy storage apparatus, and, if Wa
