4 FAQs about Monrovia energy storage peak shaving project

Why is peak shaving Better Than Load shifting?

Load shifting allows for demand flexibility without compromising continuity . However, peak shaving offers continuity and peak load reduction by storing energy off-peak for later discharge on a peak, thus lessening capacity charges while also providing an opportunity for energy arbitrage .

Does peak shaving a battery save money?

According to the results obtained in this study, more than the economic savings achieved by the peak shaving operation of the storage system is needed to compensate for the battery investment, considering the typical costs of industrial battery storage.

Does fast-charging reduce optimum peak shaving level?

In general, the series in Fig. 9 reaffirm the results obtained in Fig. 8, with fast-charging as the strategy that lowers the optimum peak shaving level and, therefore, lowers the monthly average billing, followed by time-based and low-power threshold cases.

When should a battery be charged in a peak shaving application?

In a peak shaving application, the batteries must be discharged when the power demand exceeds a predefined threshold, namely the peak shaving level. However, battery charging can be performed according to different strategies: Low power threshold: charges the battery when the demand falls below a low power limit.
