IS PEAK SHAVING A NECESSITY

Peak shaving and energy storage

Dynamic peak shaving automatically manages energy usage by discharging stored energy from the battery when demand exceeds the contracted capacity. This prevents overloading, ensures grid stability, and avoids costly demand charges. It makes sure you have sufficient energy during peak demand moments.

FAQS about Peak shaving and energy storage

How does energy storage facilitate peak shaving and load shifting?

Energy storage can facilitate both peak shaving and load shifting. For example, a battery energy storage system (BESS) can store energy generated throughout off-peak times and then discharge it during peak times, aiding in both peak shaving (by supplying stored energy at peak periods) and load shifting (by charging at off-peak periods).

Should you use battery energy storage for peak shaving?

The potential for cost savings when utilizing battery energy storage systems for peak shaving is significant. Considerable savings are even further evident for high-power demand loads like DC fast electric vehicle charging stations. The rapid increase in power demand while charging an EV can strain a local grid.

What is peak shaving?

Peak shaving is a term used in energy management to describe reducing the energy consumed during peak demand on the electric grid. Peak demand is a period when energy consumers use the most amount of electricity. Peak demand is usually in the morning when people wake up and in the evening when they return home from work.
