> The ISOs managing grids cares about the GWs and expects batteries to optimize their utilization to create the largest value for the grid enabling them to balance supply and demand. Like how they expect coal plants to manage the size of their coal pile without having to be told how to do it. What you're saying is that the ISOs care about how they can much peaker capacity these batteries can replace. That makes "Nuclear plants" an interesting metric for comparison doesn't it? Ultimately, the important measure is how many tons of CO2 these batteries can prevent from being put into the atmosphere by gas peaker plants, which are their direct competitors. Something that is actually perfectly illustrated by the graph you've posted. You can see the usage of gas and imports reducing as renewables rise while the nuclear line does what it does, stay constant. The purpose of the batteries is to reduce the gas and imports lines to what they are while the renewable lines are at their peaks.
