Peak Load

When a company consumes a large amount of electricity at certain peak times – for example when several machines or systems are operated simultaneously – this creates an increased load on the power grid. This short-term maximum power draw is referred to as a peak load.

How do peak loads arise?

Peak loads frequently occur when several energy-intensive processes take place at the same time. In industrial and commercial operations, this can happen, for example, when production systems are started up or when several electrical loads are operated simultaneously.

Economic significance for companies

The level of the peak load plays an important role in the calculation of grid charges. Many electricity tariffs contain so-called demand charges, which are based on the highest measured power draw.

The higher a company’s peak load, the higher its annual electricity costs can therefore be.

Reducing peak loads

Companies can reduce peak loads through various measures. These include, for example, peak shaving, in which electricity consumption is distributed over time or cushioned by storage systems.

An industrial storage system can provide additional energy when electricity demand rises sharply at short notice.


Frequently Asked Questions (FAQs)

What is a peak load?

A peak load refers to the highest short-term power draw of a company or consumer within a particular period.

Why do peak loads arise in electricity consumption?

Peak loads frequently arise when several energy-intensive systems or machines are operated simultaneously.

Why are peak loads relevant for companies?

High peak loads can lead to higher demand charges and grid charges, since they determine the maximum grid load.

How can peak loads be reduced?

Peak loads can be reduced through load management, intelligent control of systems or through the use of battery storage.

What role does battery storage play in peak loads?

Battery storage systems can provide additional energy when electricity consumption rises sharply at short notice, and thereby reduce peak loads.
