Why battery storage for businesses may be worthwhile in 2021
While private individuals draw their motivation for a home storage system from their commitment to a sustainable energy supply, profitability plays a much greater role for business and industry. While you certainly want to make your business sustainable - otherwise you probably wouldn't be reading this blog post - the endeavor should also be profitable.
In this article, we'll show you why the popular belief that electricity storage is only profitable with lavish subsidies and generous rebates no longer holds true, and why and for whom commercial storage may be worthwhile in 2021.
How do commercial battery storage facilities work?
In principle, electricity storage units for commercial and industrial applications function in exactly the same way as their smaller siblings for the home. They make energy available for flexible use at any time. The most classic use case is in conjunction with a solar system. If a lot of energy is generated by the PV system during the day, it often happens that electricity consumption is lower than generation. Without a storage system, this energy would be wasted. With a battery storage system, excess electricity can be collected and then used in times of bad weather. But even without a PV system, electricity storage can be profitable.
Steadily falling battery storage prices
For a long time, electricity storage systems were unprofitable and expensive, which is why progress in electromobility has been so slow. But times have changed - the production of lithium-ion batteries has picked up strongly in recent years and is expected to reach a capacity of 1.3 TWh by 2030 , a quadrupling of production capacity in 2019. The price of lithium-ion batteries , on the other hand, has fallen by ~88% from 2010 to 2020. This is also reflected in the storage market, with approximately 88,000 home storage units installed in the home sector in Germany in 2020. im Jahr 2020 ca. 88.000 Heimspeicher installiert. Auch der Commercial storage sales also increased by ~23% percent in 2019.
In addition, there are numerous subsidy programs for PV systems & electricity storage in the DACH region, also for businesses. Below you can see a summary of the funding programs of the EU, Germany incl. the individual countries, Austria and Switzerland. The information below can also be found in the pv-magazine's funding atlas.
Commercial storage reduces your operating costs - even without photovoltaics
For home consumption, it's clear: an electricity storage system coupled with the PV system makes you independent of rising energy prices and helps to sustainably reduce energy costs in the household. But what about commercial customers, who often have to pay much lower electricity costs? Here, too, it is often worthwhile to install an electricity storage system.
In addition to the classic application with a PV system to increase self-consumption, there are interesting ways to reduce operating costs, especially for businesses. For companies with high peak loads, for example when starting up production machines, a commercial storage system can reduce power prices.
Offer charging stations
If you want to offer the possibility to charge electric cars, it may well be that your grid connection capacity is too low and you will have to pay expensive fees to your electricity provider to increase the grid connection capacity. This is especially relevant for fast charging stations. Here a commercial storage system provides a remedy: it can be charged continuously with the low grid connection power and provides the necessary power when an electric car is connected to the charging station.

Individual consideration is necessary
In general, economic efficiency is always related to the specific project. Contact us today and we will check together with our partners whether you have the prerequisites for economic operation. For this purpose, we at STABL Energy are available as inverter manufacturers together with our partners as consultants.
The fact that electricity storage systems are expensive and only something for sustainability enthusiasts is no longer the case in 2021. Thanks to falling storage prices, the wide range of possible applications and attractive subsidy programs offered by the federal states, you as a business owner can make your operation more economical in a sustainable way. Finally, we at STABL Energy have a tip for you:
Keeping efficiency in mind!
An important consideration in operating costs that is often overlooked is the efficiency of the system. During the storage and discharge processes, losses occur due to energy conversion, which can have a negative impact on operating costs. The inverter, in particular, plays a significant role here. Learn more about how STABL Energy's inverter outperforms conventional inverters in terms of efficiency on our website.
