BESS systems — battery storage for commercial use

The Danish electricity grid is undergoing rapid change. More renewable energy is leading to greater price volatility, and the electrification of industry and transport is increasing the load on the grid. This presents challenges — but also concrete opportunities for businesses that act wisely.

A BESS (Battery Energy Storage System) enables your business to store electricity and use it strategically: when prices peak, when the grid is under strain, or when your own solar generation does not match your consumption. And with TSG as your partner, battery storage integrates seamlessly with solar panels, charging points and payment solutions.

TSG supplies BESS solutions ranging from 250 kW to several MWh — sized to suit your operations and tailored to the Danish energy market.

What a BESS system can do for your business

Cut energy costs

Charge the battery when electricity prices are low. Use the energy during peak hours and significantly reduce your power charges.

Earn money from system services

Supply FCR, aFRR and FFR directly to Energinet. Batteries respond in milliseconds and are the most competitive technology for grid balancing. The service runs automatically, 24/7.

Improve security of supply

A BESS provides backup power in the event of a power cut. Critical installations — production lines, refrigeration systems, data centres — continue to operate without interruption.

Make the most of solar panels

Surplus electricity generated by solar panels is stored and used when electricity prices are high. A high level of self-sufficiency and an improved ESG profile.

One partner for all your energy needs

TSG is more than just a BESS supplier. Because we cover the entire energy infrastructure, we can combine solutions so that they reinforce one another:

  • BESS + solar panels (TSG Solar): Maximise self-consumption and participate in the energy market
  • BESS + charging points (TSG Charge): Controlled charging with peak shaving — avoid power spikes from the charging point
  • BESS + payment and management systems (TSG Systems): A single integrated platform for energy, transactions and operations

This is precisely where TSG offers a unique advantage: not individual deliveries, but intelligent, comprehensive solutions — designed, installed and serviced by the same group.
