Battery energy storage for peak-shaving household energy

What is peak shaving in battery energy storage?

Battery energy storage systems (BESS) offer a host of benefits to your wider energy management strategy. One aspect of this, which can be vital to addressing rising energy costs, is known as peak shaving.

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.

How can on-site generation and battery storage improve peak shaving?

Sites with on-site generation such as solar can combine this with battery storage to make their peak shaving of electricity even more effective. On-site generation technologies are already effective at reducing a site’s grid electricity demand, but struggle to provide guaranteed peak shaving due to the inflexible nature of their generation.

How can a battery energy storage system improve battery life?

Self-consumption and oversized photovoltaic integration with batteries is analyzed. Peak shaving level is optimized for each strategy, maximizing monthly savings. Battery lifetime analysis emphasizes the strategies’ impact on battery degradation. Battery energy storage systems can address energy security and stability challenges during peak loads.

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.

What is battery energy storage?

Battery energy storage helps to resolve that problem, ensuring electricity generated when the sun is shining is available when needed for peak shaving. Peak shaving in practice can be difficult to manage effectively, and typically requires the support of an experienced partner to ensure that maximum savings are secured.
