The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations. In September 2021, DOE launched the Long-Duration Storage Shot which aims to reduce costs by 90% in storage systems that deliver over 10 hours of duration within one decade. The analysis of longer duration storage systems supports this effort.
Building energy flexibility (BEF) is getting increasing attention as a key factor for building energy saving target besides building energy intensity and energy efficiency.

This study concludes that the maximum PV penetration will be equal to whatever the minimum load is on that specific feeder. That minimum load was assumed to be 25% of the maximum load on the feeder in [13], and if the PV penetration were 25% of the maximum load, only insignificant overvoltages occurred.
