Also in operation at night - industrial and commercial operations

Given the current situation with sharply falling prices for PV and battery storage systems, rising electricity procurement costs, ambitious climate targets and the growing need for security of supply, it is clear that the use of decentralized, renewable energy systems will play an increasingly important role in industrial and commercial operations. Especially in these applications, linking PV systems with battery storage systems leads to considerable cost savings in power procurement - irrelevant whether through self-consumption, peak-shaving or also combined as a backup power system.

Peak Shaving - Compensation of peak loads

The amount of electricity required by every company, whether in office buildings, in the manufacturing industry or on farms, changes not only during the course of a day, but also every day of a week. In general, no specific measures are taken to compensate for fluctuations in demand, which are reported as consumption peaks. In commercial operations, these peak times usually occur at noon and in the evening, while on agricultural holdings they usually occur in the morning and in the evening.
Regardless of when peak loads occur in your company, they usually still determine the price you pay for electricity and thus make a significant contribution to the total cost of the electricity you use. This is because the highest consumption recorded is generally used to determine the electricity price.
Here the use of a battery storage system to cover the energy demand at peak times can mean significant cost savings. If this storage system is also combined with a PV system, the cheaper electricity generated by the PV panels can be used to charge the batteries instead of using the more expensive electricity from the grid. In many cases, peak loads can also be compensated by correlating the power usage patterns with the electricity from the PV system.

Self-consumption optimization - electricity at the right time

In addition to reducing peak loads, a battery storage system of the right size can also be used to optimize your self-consumption. If the electricity you generate from the PV system is not sufficient to cover the load, the electricity is taken from the battery storage. This means that a large part of the electricity you need in the evening can be covered very cost-effectively by the electricity generated by the PV modules during the day. You can also achieve even more savings by operating the battery storage system at the lowest tariff, i.e. charging at the lowest electricity price.
The installation of a battery storage system to increase the amount of electricity generated by small and medium-sized enterprises is an extremely beneficial approach in many places. The benefit of self-produced electricity, i.e. the reduction of the amount of electricity from the grid minus the missing feed-in tariff and the associated savings in electricity procurement costs, is greater than the investment required for the purchase of a storage system for excess PV electricity.
