BESS
As renewables rise, so does volatility. We bring balance – and business – with battery storage
Turning Green Energy into Real-World Stability
Battery Energy Storage Solutions (BESS) represent a strong opportunity for Copenhagen Merchants Group – driven by macro trends, sustainability goals and internal synergies.
With Danish energy consumption expected to double by 2050 and renewables rising to nearly 100%, large-scale storage is essential to balance the grid and make full use of green energy – without increasing emissions or wasting capacity.
At the same time, BESS technology has matured, enabling large-scale investment with limited tech risk. With over 30 years of terminal operations and available infrastructure, Copenhagen Merchants Group can leverage existing assets to enter a growing, future-proof market.

6Sites
Our six BESS sites are located across Denmark and cover both DK1 and DK2, giving us broad exposure to the Danish power market and a strong platform for delivering flexibility where the grid needs it most.
250MWh
Our six BESS projects represent 250 MWh of flexible capacity, strengthening the ability to balance renewable power across the grid. This corresponds roughly to supporting around 20,000 households during periods of peak demand.
Why Energy Storage Matters
+70% demand: Nordic consumption set to rise from ~380 TWh today to ~650 TWh by 2040
2× renewables: By 2040, Denmark’s installed wind + solar could supply twice peak load
Fossils phased out: Stable coal and gas plants are leaving the mix
BESS balances: Stores surplus green power and delivers it when the grid needs it most
How does it work?
Battery Energy Storage Systems
Battery Energy Storage Systems
Battery Energy Storage Systems (BESS) are designed to store electrical energy and release it when needed – creating a more reliable, flexible and sustainable power grid. A BESS typically consists of the following key components:
Battery
The core of the system. Electrical energy from renewable or conventional sources is stored in battery cells, organized into modules and packs. Stored energy can then be discharged to homes, businesses, industries, or directly into the grid.
Battery Management System (BMS)
The BMS monitors and protects the batteries, ensuring safe charging and discharging. It keeps track of parameters such as capacity, voltage, and temperature, so the system remains reliable and long-lasting.
Power Conversion System (PCS)
The PCS converts electricity between direct current (DC) and alternating current (AC). During charging, AC power from the grid or renewables is converted into DC and stored. When discharging, stored DC power is converted back into AC for use in the grid or applications.
Electric Energy Management System (EMS)
The EMS acts as the “control center” of the BESS. It decides when to store and when to release energy, based on grid needs and market signals. By coordinating all components, it ensures optimal performance and efficiency.
Security System
Supporting systems keep the BESS safe and stable. HVAC units regulate temperature and humidity, while fire protection systems detect smoke and prevent incidents.
