Forecast Tab

The Forecast Tab allows the long-term forecaster to view the forecast results. The top part of the Forecast Tab displays the actual and forecast values. The bottom part shows a grid with monthly data for a variety of forecast concepts. The Toolbar and View menus provide several standard options to control the way the data are presented. These include:

  • View > With Losses. This option shows monthly values including losses.
  • View > Annual Data. This option shows monthly values including losses.
  • View > Show Chart. This option turns the chart on and off.
  • View > Show Grid. This option turns the grid on and off.
  • View > Zoom. Zoom options are All, 1 Year, 6-3 months.
  • View > Data Range. Set the time range of the data to view.
  • View > Options. Include Zero, Variable Scale, Fixed Max/Min.

Drop-down lists on the Toolbar control the data that are shown. The first drop-down list is used to select the long-term model. The second drop-down list controls selection of the model contributor. The third drop-down list selects the energy concept to show. The final drop-down list selects the forecast scenario to view.

Forecasts can be viewed for a wide variety of energy concepts which are selected in the third drop-down list. These include:

  • Energy, HLH Energy, LLH Energy
  • Average MW, Average HLH MW, Average LLH MW
  • Peaks – Customer Peak (CP) or POD noncoincident peak (NCP)
  • Coincident loads at time of Customer (CP), GSP, TTSL, and CA peaks
  • Minimum load, Minimum Ratio, HLH Fraction
  • Coincidence Factors – Customer, CA, GSP, and TTSL
  • Load Factor, MVar, Power Factor

For a selected concept, several project data series are shown:

  • Actual. Actual monthly value.
  • Normal. Predicted value with normal weather.
  • Unadjusted. Statistical model forecast without calibration adjustments.
  • Calibrated. Statistical model forecast calibrated to Customer forecast (POD only).
  • Forecast. Calibrated forecast with user edits.
  • Project. Incremental load from associated Projects.
  • Total. Statistical forecast with calibration and edits plus Project forecasts.

Users can edit the forecast by typing directly in the grid in the Forecast column by typing or pasting values into the grid. Also, the right-click menu provides an Adjust Values Dialog with options to Add, Multiply or Set values. Only the forecast at the POD level can be edited. Customer Level forecasts will be re-computed from the edited POD level values.

When a user begins to edit data, a transaction will be started and the Save Changes and Discard Changes buttons on the Toolbar will be activated. Changes to a selected concept are applied to related concepts as described in the Monthly Data topic. In addition, the Total column is always recomputed to be consistent with the Forecast and Project columns.
