Solar Capture Rate

THE cannibalization metric — solar-weighted vs flat average LMP

What It Does

Solar capture rate: Capture Rate = Solar-Weighted Average LMP / Flat Average LMP. A rate of 0.80 means solar earns 20% less than the flat average. CAISO SP15 capture rates have been declining steadily as more solar comes online.
