This paper discusses reverse power flow from a home co-generation system (H-CGS) in terms of energy conservation and influence on electric power systems. Data of actual electricity and hot-water demand observed in a family including 2 adults and 2 children for a year was used as a case study for a typical installation. When the reverse power flow is allowed with the exception during mid-night, considering the influence on electric power system, the reduction in annual primary energy consumption can be increased by about 40% relative to that in the operation without reverse power. The reverse power flow is large during the daytime in winter-season, because the power output of H-CGS is large for meeting large hot-water demand. Even if the reverse power is allowed throughout a day, the primary energy conservation is almost same with that in part time reverse power operation, while the reverse power during mid-night is as large as that during daytime. Finally, the economic value of reverse power flow as a measure for reducing CO<sub>2</sub> emission was evaluated. The result shows the economic value of reverse power flow in PR operation corresponds to 23,000 yen/t-C.
