Combined Wind and Solar

This dashboard provides the most recent and day-ahead forecasted wind and solar production amounts, both of which are derived using the High Sustained Limit (HSL) from Current Operating Plans (COP) of Wind Generation Resources (WGRs) and PhotoVoltaic Generation Resources (PVGRs), as well as the Wind and Solar Generation Hourly Averages up to the latest hour ending. 

The Wind Generation Hourly Average is represented with the solid blue line. The Solar Generation Hourly Average is represented with the solid orange line. The Combined Generation Hourly Average (a combination of the Wind and Solar values) is represented with the solid purple line.

The Wind COP HSL and Day-Ahead COP HSL are represented with dotted blue lines. The Solar COP HSL and Day-Ahead COP HSL are represented with dotted orange lines. The Combined COP HSL and Day-Ahead COP HSL are represented with dotted purple lines.

Note that the most recent and Day-Ahead COP HSLs are expected to be equal to or less than the Short-Term Wind Power Forecast (STWPF) and/or the Short-Term PhotoVoltaic Power Forecast (STPPF) for the corresponding time horizon. Also note that the drop-down selector at the bottom of the screen allows for views of the High Sustained Limit, the Short-Term Power Forecast, and the Resource Power Potential. 

Our forecasts attempt to predict HSL, which is uncurtailed power generation potential. This graph plots actual system-wide wind and solar generation, which is impacted by curtailment, shown as “Wind Gen Hourly Avg”, “Solar Gen Hourly Avg” and “Combined Gen Hourly Avg”. Because of this, the data in this graph should not be used to evaluate forecast performance. Steps will be taken to include Actual System-wide HSL in this graph in the future.

The following reports provide similar data points but may not provide a one-to-one match with the values currently displayed in the dashboard:

• NP4-732-CD - Wind Power Production - Hourly Averaged Actual and Forecasted Values
• NP4-742-CD - Wind Power Production - Hourly Averaged Actual and Forecasted Values by Geographical Region
• NP4-737-CD - Solar Power Production - Hourly Averaged Actual and Forecasted Values
• NP4-745-CD - Solar Power Production - Hourly Averaged Actual and Forecasted Values by Geographical Region
