Forecast Tab

The Forecast Tab displays the interval forecast for the selected Medium Term Forecast. Three selection boxes on the toolbar control the data selection.

  • Medium Term Forecast Selection. This selection box specifies the Medium Term Forecast scenario.
  • Schedule Selection. This selection box specifies the contributing Schedule.
  • Contributor Selection. This selection box specifies the contributor to the Schedule. The first item in the selection box, "(All Contributors)", shows sum of all contributors to the Schedule.

The display consists of two parts. The top panel, Chart View, graphically shows the interval forecast. The bottom panel, Grid View, numerically shows the final forecast.

Chart View

The Chart displays three series. These series are described below.

  • Forecast. The final forecast including all adjustments and overrides.
  • Actual. The actual values when they exist.
  • Model. The model forecast values.

The series may be toggles on and off using the selection box in the upper right corner of the chart. Numerical values for a month may be viewed by moving the mouse over the chart. The full range of forecast data is available for viewing. However, the displayed range is based on the Zoom and the Data Range Selection Bar.

Grid View in Multi-Day Zooms

At these zoom levels (5 day, 7 day, …, All) the grid will show the Forecast values with one row for each forecast day with daily statistics shown in the last three columns. The values in the grid can be edited by direct entry or by using the Right Click menu options, Adjust Values, and Install Selection.

Grid View in One-Day or Two- Day Zoom

At these zoom levels (1 day, 2 day), the columns are used to show comparisons of the Forecast. The top rows show statistics for the column. In one-day zoom, these are statistics for that day. In two-day zoom, these are statistics across the two days. Statistics in each column are followed by interval data with one row per interval. The columns correspond to the displayed Chart series. The values in the grid can be edited by direct entry or by using the Right Click menu options, Adjust Values and Install Selection.

Right-Click Menu

On the Forecast Tab grid, the final forecast values can be modified through direct entry or by using the Right-Click menu.

  • Direct Entry. The user can directly enter forecast values on the Forecast Tab in multi-day views and in the Forecast Column in 1-day and 2-day views.
  • Install Selection. This option is available only on the 1-day and 2-day views. It allows the user to install a segment of data from one of the forecast steps (an individual weather provider forecast, Unadjusted model forecast, Tuned forecast or Scaled forecast) and install the selection as the Forecast. This operation copies the data from the selected segment and pastes the values into the Forecast column.
  • Adjust Values. In multi-day views, the Adjust Values option brings up a list of adjustment macros that will be applied to the selected forecast cells or to the selected column. In 1-day and 2-day views, the Adjust Values option is only available for the Forecast column.

The Right-Mouse Menu allow quick access to modifying the forecast using the Adjust Values and Install Selection option.

When the range is a part of a day, three Adjust Values options are enabled.

  • Add to Values. This option brings up an Adjust Values text box. Enter the value to add and press OK. The entered value will be added to all of the selected cells.
  • Multiply Values. This option brings up an Adjust Values text box. Enter the multiplier value (e.g., enter 1.02 to increase by 2%), and this multiplier will be applied to all of the selected cells.
  • Set Values. This option brings up an Adjust Values text box. Enter a value and this value will be pasted into all of the selected cells.

When the selected range is an entire day or set of days additional Adjust Value options are available. Some of these options involve adjusting maximum or minimum values up or down while adjusting other intervals to hold total energy for the day fixed. The offsetting adjustments are made proportional to the distance of each interval from the peak value in the case of an adjustment to the daily peak. When both maximum and minimum values are adjusted, the offsetting adjustments are made proportional to the distance of each interval from the midpoint of the load range.

  • Add Energy (e.g., add 500 MWh). This is the same as Add to Values
  • Multiply Energy (e.g., 1.02 for a 2% increase). This is the same as Multiply Values
  • Add Peak (e.g., add 30 MW to the peak). This adjusts the daily maximum to the desired value keeping total daily energy the same
  • Multiply Peak (e.g., 1.02 for a 2% increase to the peak). This adjusts the daily maximum value by the multiplier keeping total daily energy the same
  • Set Maximum (e.g., set peak to 500 MW). This sets the daily maximum to the entered value keeping total daily energy the same)
  • Set Maximum & Minimum (e.g., set peak to 500 MW and minimum to 250 MW). This sets the daily maximum and minimum to the entered values keeping total daily energy the same
