Energy Management System (EMS)

Why have your own system?

We couldn't find a solution on the current market that met our expectations.

Our EMS was developed as proprietary software so that we could have full control over energy technology management and offer our customers solutions that truly correspond to today's energy sector. It was designed by a team of IT and energy specialists and combines work with data, predictions, operational logic, and economic management. Thanks to its cloud-native and API-first architecture, it can be easily expanded, connected to other systems, and operated from anywhere, without the limitations typical of universal third-party platforms.

Low level of management

At the basic level, EMS ensures the safe and stable operation of the entire storage facility. It controls communication with batteries, inverters, safety features, HVAC, heating, and fire systems, and keeps all components in a defined mode without the need for operator intervention. It thus forms a reliable foundation on which higher predictive and economic logic can be built.

High level of management

In the upper layer, EMS works with real-time data and predictions—it evaluates electricity and gas prices from the OTE exchange, monitors weather forecasts and expected PV production, plans consumption for the site, and can estimate the energy balance in advance. Based on this information, it decides when it is advantageous to charge the battery, when to store energy for its own consumption, and when to automatically sell the surplus. This significantly shortens the return on investment, as the storage facility not only provides technical support for the site, but also acts as an active economic element.

EMS also coordinates the operation of photovoltaic power plants, batteries, cogeneration units, vehicle charging, and heating equipment. It can calculate when it is advantageous to generate heat from cogeneration units, when to store energy, when to purchase it cheaply at low or negative prices, and when it is effective to change the flow of energy to the grid. This ability to make automatic decisions and optimize trading can reduce the return on investment of storage even further compared to conventional systems.

SCADA

Our EMS includes our own SCADA, which unifies all technologies into a single, clear interface. It enables detailed monitoring of BESS, PV, KGJ, charging stations, and other devices, including working with historical data and remote control. We can connect to the customer's existing SCADA systems or replace them with our solution and connect data from already installed and newly delivered technologies into a single unit.

Peak shaving

Trimming the edges in both production and consumption.

Whenever additional machines that require high power for a short period of time are switched on during production, this is reflected in your electricity bill. Battery storage provides additional energy and covers short-term peaks in consumption. You can thus reduce the power consumption you have reserved with your energy provider and save money.

Advantages:

1. Reduction in reserved power consumption
2. More self-sufficiency
3. Reduction of penalties for exceeding consumption limits

Suitable for industrial enterprises, especially manufacturing and energy-intensive companies.

Load leveling

Peak shaving with a schedule that determines how the battery storage will be charged/discharged based on known data or weather conditions. The PLC then discharges/charges the batteries according to the requirements of the scheduled window. However, even in this mode, peak shaving takes priority so that the customer never exceeds their quarter-hourly maximums.

Fail-safe mode

Production backup similar to UPS (backup system). In the energy unit, inverters run separately at the input and output, with battery storage between them. This feature is useful for customers who work with sensitive equipment or substances (robotic manufacturing, chemical production). If you do not need a completely fail-safe system, we can offer a solution that works with a failure time in the order of milliseconds.

Start from dark

A blackout can threaten both consumers and power plants themselves (if they do not have island operation secured). For power plants, BESS can become a third source of energy that they can use in the event of a failure of the main and backup energy sources, or it can function as the main backup source. Thanks to BESS, a power outage can be a momentary issue that has only a minimal impact on operations. For consumers, BESS can be the only backup source that offers energy to restore appliances immediately. The storage facility is capable of starting up on its own without an external network.

Frequency control

The frequency in the grid may fluctuate outside the specified range. The BESS system is capable of charging and discharging at the power level, installed capacity level, or according to preset combinations of operating modes. These actions return the frequency to the required range in real time (within seconds).

Power factor regulation

Suitable for industrial enterprises, especially manufacturing and energy-intensive companies. The main purpose of reactive power compensation is to reduce the apparent power consumption and the current flowing through the power supply line. Compensation is therefore an important energy-saving measure that reduces the load on the power line, thereby reducing losses and increasing the service life of the line.

Voltage regulation

The voltage in the network may fluctuate due to various influences. BESS It is capable of automatically regulating voltage by charging and discharging batteries. For energy producers, battery storage increases the resilience of equipment against adverse effects originating from the central grid.

Island mode

Your independence from the network

In areas with insufficient electrical grid coverage, a combination of electrical power sources can be used. (PV, KGJ, etc.) and battery (BESS). Excess electrical energy is stored in it at times when its production exceeds consumption (for example, when the sun is shining and consumption is not so high), and this energy is consumed at times when consumption is higher than what the connected source is capable of producing.

Power Balance Services

We are able to meet the conditions for providing power balance services (mFFR, aFRR).
