    ・Your understanding is appreciated that it will take approximately 5 to 10 minutes for the hourly results to show. Also, data cannot be updated from 0:00 to 1:00.
    ・For example, the hourly result for the 9 o'clock hour refers to the average electricity demand from 9:00 to 10:00.
    ・The maximum demand forecast and the hourly demand forecast are based on weather forecasts and actual demands, therefore the actual results may vary.
    ・"Five minutes intervals data" of the hourly demand forecast may not be temporarily shown due to communications problems.
    ・The maximum demand forecast, peak supply capacity and the hourly demand forecast may be suddenly revised in accordance with the status of supply and demands.
    ・The "Demand Forecast" will be posted from December 2nd to March 31th for the hours between 9:00-20:59 except on Saturdays, Sundays and Holidays.
    ・The specification of csv data may be revised without any prior notice.
    ・Due to the rounding off numbers, the actual hourly demand and the average of the five minutes interval data may not be equal.
    ・The peak supply capacity includes, electricity supply capacity, which is matched to the peak load (maximum capacity), comprised of base load capacities such as thermal and nuclear power, and pumped storage power which has a quick response generating capability when the demand and supply of electricity becomes tight. Furthermore, during urgent circumstances when electricity demand exceeds supply capacity, pumped storage power plants will be able to generate as an additional temporary source of electricity supply, but due to the limitations of continuing generation, pumped storage power has been excluded from the peak supply capacity.

Explanation of the colors used in the rate of electricity use
It indicates the tightness of electricity supply and demand condition (by colors) according to the consumption rate.
The calculation method of consumption rate
The consumption rate is calculated by dividing the total electricity consumption (total demand) by available electricity (total supply).

Information
March 28, 2019
On March 28, 2019, our website started providing information on solar power generation amounts and predicted highest temperatures.
December 1, 2018
Since December 1, 2018, our website has started offering power utilization forecasts of peak time zones when power utilization is at a maximum and supply becomes tight because of high demand.
April 1, 2016
As full liberalization of the electricity retail market began in April 2016, TEPCO Electricity Forecast shows electricity demand and supply in the service area, including not only TEPCO Group but also other electric power companies.
