Peak Shaving – saving energy costs by smoothing load peaks
The network user charges, which are based on the highest purchased service in the billing period (monthly or annually), account for a large proportion of electricity costs. The more uniform the electricity purchase, the lower the price of the electricity usage charges, hence lower electricity costs.
Battery storage provides the ability to time-intercept and reduce peak loads by discharging the stored electricity during the duration of peak loads. With optimal load management, the system keeps the total supply below a predefined level.
By charging battery storage by regenerative energies (such as PV, wind), the self-consumption rate of green electricity could be increased to a desirable level.
