peak season for energy storage demand
Peak Shaving with Solar and Energy Storage
Peak shaving involves proactively managing overall demand to eliminate short-term demand spikes, which set a higher peak. This process lowers and smooths out peak loads, which reduces the overall cost of demand charges. We believe solar + battery energy storage is the best way to peak shave.

Solar Integration: Solar Energy and Storage Basics
Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. So, storage can increase system efficiency and resilience, and it can improve power quality by matching supply and demand.
