	Traditionally, there are close relation between load dispatching operation of power system and meteorological phenomena, such as demand fluctuation and temperature, hydro power generation fluctuation and precipitation, and faults and extreme weather like lightnings or typhoon. Load dispatching operators of power system, by gathering and utilizing available meteorological information, continuously monitor the constantly changing power demand and the power plant operation level to perform power supply demand management and power system operation. In recent years, the load dispatching operation of power system in Japan has been changing by the increase of extreme weathers and the rapid introduction of renewable energy like photovoltaic and wind generation. Thus, the highly accurate prediction and observation of weather condition are necessary to accomplish efficient load dispatching operations. Considering the evolving environment of the load dispatching operations, our R&D Investigation Committee examined the relation between load dispatching operation and meteorological information, the collection method and utilization of meteorological information, and the changes in load dispatching operation caused by the further introduction of renewable energy. Moreover, we have summarized possible issues and future visions on the expansion of renewable energy. In addition, we have investigated fault cases in power system both in and outside of Japan that are caused by extreme weathers.
