Real-Time Data Shows Energy Storage Smoothing
Below, real-time graphics show how the batteries work to smooth solar power when clouds are present. The batteries react to the sudden decrease in power output by immediately discharging the exact amount of stored power needed to fill the gap created by the clouds. When the battery system is smoothing it dispatches power in a consistent manner for continuous power, despite fluctuations in solar output.
When the battery system is shifting, it is dispatching stored power onto the grid. See real time shifting simulation here.
