If you don’t manage your energy, you’ll pay the price.
Negative electricity prices, peak loads, lost self-consumption, a battery that’s half empty at the wrong moment—these aren’t just bad luck. They’re management issues. An EMS solves them.
Your system generates electricity. An EMS decides what happens to it.
An Energy Management System is software that actively controls your energy system. It continuously collects data: how much your system produces, how much your business consumes, what the electricity prices are on the market, and how the battery is currently performing. Based on this information, an EMS makes decisions automatically.
Five problems that disappear with the right control
Negative Electricity Prices
When your system feeds power into the grid at a time when the electricity price is negative, you pay to get rid of energy. When combined with a BESS, an EMS will proactively monitor this and store excess energy for later use.
Excessively high capacity charge
Your capacity charge is based on your highest 15-minute peaks per month and is billed annually. Just one extra peak costs you more than you might think. An EMS smooths out those peaks—even when the sun isn’t shining.
Lost self-consumption
Solar energy that you consume yourself is more valuable than electricity you feed back into the grid. An EMS coordinates production and consumption so that your solar energy delivers maximum returns.
Feed-in Limits and Grid Congestion
At locations with limited feed-in capacity, an EMS automatically controls your battery or flexible consumption points, such as charging stations. This allows you to fully utilize your system without overloading the grid.
Multiple assets, no coordination?
Do you have solar panels, a battery, and/or charging stations? Then you need a system that coordinates everything. Without an EMS, these three operate according to their own logic. With an EMS, they work as a unified whole: tailored to your consumption, the market, and your energy needs.
What an EMS Actually Does for Your Business
Three situations that occur daily in industrial and logistics environments—and how an EMS solves them.
Storing Excess Energy
Massive renewable energy production on the grid, low demand: the price goes negative. Anyone feeding power back into the grid at that point literally pays. An EMS detects these moments in advance based on market data and directs your battery to store excess energy instead of feeding it into the grid. You can then use that stored energy later when the price is positive.
Reduce Your Peak Consumption
When multiple processes run simultaneously, your consumption spikes briefly but sharply. That 15-minute maximum determines your capacity rate. An EMS recognizes this rising demand and automatically activates your battery to smooth out the peak. This results in lower total grid costs.
Smart scheduling for charging stations
Charging electric vehicles during peak times can significantly drive up your capacity rate. An EMS integrates your charging stations into the overall energy balance: when PV production is high and consumption is low, you charge at maximum capacity. When grid rates are high or your processes are already drawing a lot of power, you charge at minimum capacity. Automatically, without human intervention.
Frequently Asked Questions About EMS
An EMS continuously collects data from all energy assets in your business: your PV system, battery, consumption meters, and, if applicable, market prices. Based on that data, it automatically makes decisions about charging and discharging your battery, controlling flexible loads, and optimizing your energy balance. This happens in real time, without requiring any manual intervention.
A BESS (Battery Energy Storage System) is the physical battery: the hardware that stores and releases energy. An EMS is the software that decides when that battery charges or discharges—and based on which parameters. A BESS without an EMS is like a tank without a steering wheel: the capacity is there, but the intelligence is missing. Both are needed to harness the full potential of energy storage.
A BMS (Battery Management System) monitors the internal condition of the battery itself: cell voltage, temperature, state of charge, and safety. It is a protection system for the battery hardware. An EMS operates at a higher level: it decides when and how the battery is used within your overall energy system, based on market prices, consumption patterns, and grid conditions. BMS and EMS work together but fulfill fundamentally different roles.
No. EMS systems vary greatly in terms of their level of intelligence, the assets they can control, their integration capabilities with external data signals (such as market prices or weather forecasts), and the way they are configured. A generic, pre-configured product performs differently than an EMS that is configured for your specific installation, your consumption profile, and your energy needs. At Solora, we always tailor the EMS to your specific situation.
An EMS malfunction has no impact on your power supply or the operation of your system. Your solar panels will continue to generate power and your battery will continue to function—only the active optimization will be suspended. Solora monitors your systems remotely and is automatically alerted in the event of anomalies. We intervene proactively before a malfunction affects your energy efficiency.
That risk exists with suppliers who use closed systems and proprietary protocols. Solora prefers to work with open standards and systems that can be integrated with existing infrastructure and future technologies. We discuss this transparently during the proposal phase so that you know what the integration options and exit flexibility are.
Cybersecurity is a real concern with any digital energy solution. A properly configured EMS features secure communication protocols, segmented network access, and limited external attack surfaces. During implementation, we take your existing IT infrastructure and your industry’s requirements into account. For specific questions about security architecture, we’d be happy to discuss the details with your IT manager.
That’s a common misconception. Energy management isn’t reserved for large industrial players. An EMS tailored to an SME operates on the same principles—it scales with your installation and your needs. The complexity lies behind the system, not in front of it. You can see what’s happening via a dashboard; the system operates in the background. The return on investment is also tangible for smaller installations—especially when you combine a battery, a capacity tariff, and a dynamic contract.
Yes. An EMS can also be useful without a battery, for example, to avoid consumption peaks by intelligently managing flexible loads, to provide insight into your energy profile, or to prepare you for a future BESS investment. However, the full added value of an EMS—and certainly the optimization based on market prices—is only fully realized in combination with storage. We always assess what makes sense for your specific situation.
The cost of an EMS varies depending on the size of your installation, the number of assets to be integrated, and the desired functionality. A simple configuration for an SME with PV and a battery falls within a different price range than a fully integrated system for a large industrial site. The payback period is determined by the total savings: lower capacity charges, reduced losses during periods of negative prices, increased self-consumption, and any revenue from flexibility markets. In most cases, an EMS is not a standalone investment but part of a broader energy project in which the overall business case is calculated. We’d be happy to map this out specifically for your situation.
In most cases, yes. Whether your system is eligible depends on the age and type of inverters, the existing metering infrastructure, and the communication protocols supported by your current systems. Modern inverters and battery systems typically use open standards that enable integration. For older installations, an additional meter or gateway may sometimes be required. Solora always conducts a technical feasibility study before proposing an EMS integration, so you know what’s feasible and what it will require.
Monitoring records what’s happening: how much your system is generating, how much you’re consuming, and whether there are any anomalies. An EMS does that too, but goes a step further: it actively makes decisions based on that data and controls your assets. While monitoring tells you that your battery charged at the wrong time yesterday, an EMS would have prevented that from happening yesterday. Monitoring is valuable for insight and reporting. An EMS is valuable for maximizing returns.
