How Peak Shaving with Battery Storage Works. The basic concept behind peak shaving is very simple: With on-site storage, you charge your batteries whenever electricity rates are at their lowest (i.e. during off-peak hours or with your free solar energy) You then discharge those same batteries to avoid paying peak prices …

PEAK SHAVING. Load shifting, or demand response, optimizes electricity use and can reduce energy costs. While similar to peak shaving, with its goal to relieve stress on the electric grid within peak demand periods, the way load shifting achieves this is different. Load shifting involves moving energy consumption from high-demand (peak …
