Battery storage: grid charge optimization through peak load capping
One effective way to reduce energy costs in intralogistics is to avoid peak loads. The use of a battery storage system is a good idea here, because it steps in as an alternative energy supplier precisely when the company’s power consumption is particularly high – optimally adapted to the individual work processes and without interfering with sensitive production processes.
What is meant by “load peak”?
A company’s electricity consumption can be subject to extreme fluctuations depending on the time of day or season. For example, if several machines are started up at the same time, a higher amount of electricity is required. This maximum load on the power grid is then referred to as “peak load,” “load peak,” or “peak.”
Why should peak loads be avoided?
When calculating electricity costs for industrial companies, energy suppliers not only take into account the energy they purchase (= labor price), but also the peak loads that occur (= power price). As a result, electricity providers are significantly increasing electricity rates for businesses – regardless of how often the electrical load spikes occur or how long they actually last. The load peaks are therefore decisive for the calculation of the network charges by the energy supplier, which is why a reduction in load peaks leads directly to cost savings for the company.
How can peak loads be reduced?
Peak shaving (also called peak shaving or peak reduction) is the process of shaving off peak loads. There are two ways to do this:
This enables companies to avoid peak loads, for example, by delaying the start of machines or shutting down production facilities. However, this represents a serious intervention in often sensitive manufacturing processes. Alternatively, other power sources can step in during peak loads in addition to grid power, such as a battery storage system.
How does Peak Shaving work with a battery storage system?
The intelligent battery storage system steps in when a particularly large amount of energy is needed: Above a certain level, it cuts the peak loads and meets the energy demand that exceeds this level with the energy stored in the battery storage system. At times when little power is needed, the battery storage system stores new energy again to be ready for the next peak load. So as soon as a certain power threshold is exceeded, the battery storage system supplies your company with energy and thus keeps your power price low.
Optimally tuned and versatile
So peak load capping using a battery storage system is a sustainable way to drastically reduce energy costs in your business. It is important that the storage system is correctly dimensioned and optimally aligned to the individual conditions of your company. That’s why, in a first step, we analyze your operating data and create a load profile so that the battery storage system – perfectly adapted to your individual processes – can work as efficiently as possible and always provide the energy exactly when it’s needed.
Moreover, the use of a battery storage system is not limited to individual applications. Simultaneous multiple use generates synergies and significantly reduces the payback period of the investment. A combination of the different operation management strategies self-consumption optimization, peak shaving, time-of-use or charging of electric cars increases your benefit and creates sustainable added value.
