Grid scale BESS can be used for frequency regulation, peak shaving (i.e. reducing demand during peak hours to lower grid stress or avoid high tariffs) and grid stability. The 750 kW BESS project at the PECC2 Innovation Hub in Ho Chi Minh City is an example of this.
[pdf] Peak shaving refers to reducing electricity consumption during periods of peak demand when utility rates are highest. Energy storage systems play a crucial role by storing electricity during off-peak hours and discharging it during peak times, helping businesses avoid expensive demand charges.
[pdf] Lithium-ion batteries can play a significant role in both strategies—acting as the sharp edge of the energy-saving razor. Storing energy for future use is a valuable peak shaving strategy, and LiBs play a major role in these systems.
