How does storage penetration affect ELCC?
Higher storage penetration can lead to diminishing marginal ELCC as additional units compete for the same surplus energy and discharge opportunities. Duration: The length of time a storage unit can discharge at full capacity. Longer-duration storage can sustain output during extended demand peaks, increasing ELCC.
Does the ELCC of storage increase or decrease?
The ELCC of storage can increase with longer duration or changes to system conditions, such as adding more baseload/variable generation up to a point of saturation beyond which the ELCC decreases, as demonstrated in Figure 9. However, the diminishing returns from storage penetration persist regardless of these improvements.
