The visualizations show a time series plot of the outage occurrence. Outages appear in black; regular grid operation appears in green.


The variables referenced on the Reliability tab include:



Generator runtime (hours/day)

Average number of hours per day that the generator is operating

Generator O&M ($/day)

Average operational costs of the generator

Generator fuel consumption (L/day)

Average fuel consumed by the generator per day

Generator fuel cost ($/day)

Average cost of the fuel consumed by the generator per day

Battery throughput (kWh/day)

Average kWh that the battery outputs per day

Capacity Shortage Hours (hrs)

Number of hours when capacity reserve was not met



If you want to explore outages in the Time Series, then select "Grid Demand Limit". This would go to 0 whenever there is an outage.
