When you place your cursor on each graph, you can see the actual demands and forecasts.

1. Today's actual demand (1hour)
   Hourly electricity consumption actual demands are shown in a graph.
2. Today's result (5 minutes)
   Electricity consumption actual demands (provisional), which are updated every 5 minutes are shown.
3. Today's forecast
   The hourly maximum electricity consumption actual demands from 9:00am to 8:00pm on weekdays are updated at around 8:00am.
   * The forecasts may differ from the daily maximum consumption, because they are adjusted according to the actual demands on the hour from 10:00am to 8:00pm on weekdays.

Max supply capacity

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.
* In the electricity consumption status graph, peak supply capacity is indicated in a line for the "Time zone during which electricity consumption is high (9:00am - 9:00pm)" in order to compare it to the consumption status or the forecasts.
