  • *The peak demand time period and the peak usage time period in the area supply-demand forecast for the following week are time periods that the Organization for Cross-regional Coordination of Transmission Operators Japan (OCCTO) has specified as most often being the peak demand and minimum reserve rate time periods for that day based on past data. These time periods are not which maximum demand or minimum reserve rate is forecasted.
  • *These peak demand and peak usage time periods may change in the middle of the week as the OCCTO-specified time periods change by month and by the time of the month. It also differs by whether that day is a weekday, a Saturday or a holiday.
  • *The peak demand time period and the minimum reserve rate period (peak usage) may fall on the same time period.
  • *In the “Time period (flame)” row, “1” corresponds to 12 am to 12:30 am and “48” corresponds to 11:30 pm to 12 am.
  • *Past weekly forecasts are not available.
  • *The area supply-demand forecast for the following week will be posted around 6 pm next Thursday and may be updated at a later date.
  • *The forecast for two days ahead is updated every day around 6 pm and is marked with a blue box.
  • *The values to be published as the preparation notice for strain on supply-demand will be the ones that take into account additional supply capability in the actual minimum reserve time period. This may not match the forecasted values that are in the OCCTO-specified time period and do not take into account additional supply capability.
