Headroom Study

Overview

The Headroom Study page allows users to assess a scenario by year both visually and in terms of some key headroom metrics

1. The Headroom study page can be found within a Scenario in the navigation pane on the left.
2. Refresh the data if there have been any recent changes to the scenario.
3. Once in the Headroom Study Page, browse the years of your simulation with the timeline. This will generate a visualisation of generation vs load for the given year, as well as a table of Headroom Metrics. The visualisation shows a comparison of the total daily Load and Generation, holding Ctrl + scrolling will let you zoom in on the part of the graph you are hovering over.

Headroom Metrics

• Backup - This is the percentage of maximum load that the generators and battery output can supply. For example a value of 110% would be that your on site supply could meet 110% of the sites maximum demand.
• Curtailment - This is the percentage of output from energy sources of the annual generation of the site that is unable to be exported due to an undersized connection. If this were 100% it would mean none of the energy generated on the site supplied the site or was exported.
• Endurance - This is how many hours the backup batteries backups on site can last, a negative value means the on site generation can run the site indefinitely as long as they are fuelled.
• Headroom - Headroom is the maximum value of generation added to the size of the incomer divided by the demand, if this value is less than 100% then the site power will fail to meet demand.
• Provisioning - This value is the potential percentage of the total demand of the site provided by generators and batteries.
• Island Mode - Is true if the site can run independent of the grid or is false if the site dependant on the grid for importing or exporting energy.
• Incomer/Export Capacity Sufficient - Is true if the site power demand can be met without exceeding the capacity of the connection to the grid.
