FlexPower and encentive enable companies to automatically optimize their electricity consumption on the intraday electricity market for the first time.
What is a battery-simulation?
One battery-simulation is a digital analysis tool that makes the effects of a planned storage investment visible even before it is made. Based on real consumption data, dynamic price signals and realistic usage scenarios, it is possible to determine which storage strategy makes economic sense for a company. This allows companies to make well-founded decisions instead of relying on assumptions.
Why battery storage systems are gaining in importance?
Battery storage systems have long been more than just a topic of the future — they are becoming a decisive component of modern energy strategies. But why is the investment worthwhile right now? The expansion of renewable energy sources is constantly progressing — but their availability fluctuates. Sometimes there is too little electricity available, sometimes it is in abundance — with correspondingly severe price swings. It is therefore becoming increasingly important to store electricity when it is available cheaply and in large quantities from renewable sources. According to one Study by the Institute of Energy Economics at the University of Cologne does the rise volatility on the electricity market — an environment in which flexible storage solutions are becoming increasingly important.
In addition, there are new regulatory incentives to making energy consumption more flexible, the expansion of sector coupling and company-specific requirements that make battery storage economically attractive for many companies. Battery storage and other types of storage help with:
- Peak shaving
- Optimizing self-consumption
- Energy management based on price signals from the day-ahead or intraday market
- Stabilization of the power grid through short-term compensation payments
But the requirements are highly individual: consumption patterns, self-generation, electricity cost structure and purchasing strategy differ from company to company. This makes planning complex and battery simulation all the more important.
What makes a good battery-simulation stand out?
A battery-simulation is helpful for companies if it is practical, data-based and can be used strategically. The following aspects should be covered:
1. Digital image of your energy system
A good simulation realistically depicts a company's location: historical load patterns, current electricity price structures, PV generation and planned developments are incorporated. The simulation shows energy flows as if the storage system were physically on site. This allows you to monitor potential storage savings every day.
2. Variety of scenarios & goal orientation
Whether peak shaving, self-consumption or multiple goals at the same time (multi-use): Different use cases can be played out. Target figures such as profit, CO2 reduction or — depending on the application — even a higher degree of self-sufficiency are made measurable.
3. Profitability analysis
The battery simulation provides key KPIs such as payback time, savings potential and Levelized Cost of Electricity (LCOE). Operating costs with storage and without storage can be directly compared.
4. High-resolution data & realistic parameters
The simulation is accurate to a quarter of an hour, takes charging cycles into account and shows how capacity and charging performance affect the result.
5. Specific recommendations for action
A good battery-simulation answers your questions: Which type of storage is ideal for your company? What capacity and performance do you need? And how must the storage system be controlled according to design in order to develop its full potential?
Three learnings from practice
Theory is not the same as practice. That is why we have compiled the findings from various simulations that we have carried out together with companies from different industries:
- Real system dynamics count: Static models are not enough. Only dynamic simulations show the real benefits. Because power consumption and generation fluctuate throughout the day — a model must be able to capture these changes in order to deliver realistic results.
- High-resolution data is key: They form the basis for well-founded decisions. Data accurate to quarters of an hour makes it possible to see exactly when load peaks occur or when PV yields are being fed into the grid — crucial for precise design.
- Sizing is not linear: The choice of capacity and charging capacity has complex effects on profitability and savings. Larger storage is not automatically better — sometimes a smaller, more targeted solution is sufficient to achieve the highest economic benefit.
Conclusion: Battery-simulation before investment
A good battery-simulation is more than a simple calculation model. It is a strategic planning tool that minimizes risks, creates economic clarity and secures investments. Companies that invest in storage today should think of simulation and optimization together — for a shorter payback period, higher ROI, and maximum operational flexibility.
