Peak shaving, sometimes called load shedding, is the strategy used to reduce periods of high electricity demand. In this blog, our Technical Sales Manager, Jonathan Mann, explains how battery energy storage systems can help with peak shaving. Many businesses in the UK are susceptible to peak load spikes.
Peak shaving works by recognizing these high-demand durations and tactically handling energy intake to decrease the top lots. This can be attained via various approaches, such as using backup generators, moving non-essential energy use to off-peak times, or implementing power storage services like batteries.
Peak Shaving is one of the Energy Storage applications that has large potential to become important in the future''s smart grid. The goal of peak shaving is to avoid the installation of capacity to supply the peak load of highly variable loads. In cases where peak load coincide with electricity price peaks, peak shaving can also provide a reduction of energy cost. This paper …
