Smart energy storage: reduce costs and unlock new revenue streams
Modern battery storage systems today are far more than just a technical aid. They are developing into the backbone of modern energy infrastructure – as a flexible interface between power consumption, generation, and grid operation. Those who deploy such systems strategically not only reduce grid costs, but simultaneously unlock new sources of revenue and become less dependent on volatile electricity markets. A classic win-win situation, in other words.
Intelligently managing peak loads
In industry and among energy suppliers, peak loads occur regularly – for example when machines start up simultaneously or energy consumption increases sharply in short intervals. During these peak times, high grid usage costs hit particularly hard, as grid operators charge for the maximum power draw.
A battery storage system can target these peaks and, using a technique called peak shaving, essentially “break” them. With forward-looking peak-shaving algorithms, for example, excess energy is stored during low-load periods and released again during high-load phases. This smooths the load profile and reduces costs – permanently and, importantly, without operational intervention in ongoing operations.
Additional revenue from balancing energy marketing
Beyond this pure cost reduction in power procurement, a storage system opens up additional earning opportunities. Because battery systems, with their short reaction time, are ideally suited to provide balancing energy – whether for frequency regulation (primary control power) or for short-term compensation of grid fluctuations (secondary control power). However, this requires technical pre-qualification with the responsible grid operator. Once this is completed, the system can actively participate in the balancing energy market. The proceeds flow in addition to savings from peak shaving and make the operational model particularly attractive economically. Our project experience shows: when properly sized and operated, many systems pay for themselves within just a few years – while at the same time offering high flexibility in energy deployment.
Voltage under control – actively improving grid quality
Another advantage of battery storage systems, often underestimated in practice, is the provision of reactive power, which stabilizes voltage in the grid. The installed inverters can be controlled to flexibly feed reactive power in or out as needed. Particularly in regions with high levels of PV feed-in or weak grid infrastructure, this is a crucial contribution to supply quality.
A recent example came from the power outage on the Iberian Peninsula in April of this year, where a chain of technical faults, including lack of reactive power, led to widespread voltage dips. The incident clearly demonstrated how quickly a grid can become unstable and what a difference decentralized, responsive storage solutions can make.
Our systems respond in real time to such voltage fluctuations, thus protecting critical grid areas and making an active contribution to stability and supply security – all as a side benefit to their primary function.
No standard solution – size storage systems individually
Storage solutions are as diverse as the requirements they must meet. The size and configuration of a system depend on what it will be used for. Is the primary goal to smooth peak loads? Is balancing energy marketing the focus? Or should self-consumption be optimized? All these questions must be answered first.
In a first step, we analyse your load profile, assess your technical and economic objectives, and on this basis calculate the optimal storage size. Whether it is commercial storage in the lower kilowatt-hour range or a large-scale facility with several megawatt-hours in container format – we develop “your system”, one that fits your needs and operations.
