Ancillary services ensure the stable operation of the power system. Responsibility lies with the grid operators—both transmission system operators and distribution system operators. To maintain a secure electricity supply at all times, frequency, voltage, and power flows must be kept within defined limits. This does not happen automatically, but through continuous interventions as part of ancillary services.
One of the best-known services is balancing energy. Even in the event of large-scale disruptions such as a blackout, ancillary services help restore the grid quickly. Ancillary services include frequency and voltage control, system operation management, and system restoration.
We’re happy to provide you with a comprehensive insight into using our storage systems in your project.
The balancing services market is required to maintain grid frequency (50 Hz) stability:
Procurement takes place via the balancing energy market through a market-based auction process. Three products are distinguished:
The main difference lies in the speed of activation: PCR must be fully activated within 30 seconds, aFRR within five minutes, and mFRR within fifteen minutes.
TESVOLT Energy focuses on primary and secondary control reserve.
The power grid must remain stable at all times. Even the smallest imbalances between generation and consumption must be corrected.
To achieve this, grid operators specifically pay for flexible systems. Ancillary services are financed through grid fees.
Battery storage systems are ideally suited, as they:
They provide flexibility—and are remunerated for it.
Your battery alone does not generate revenue. Only through intelligent integration into energy markets does your flexibility become economically viable.
TESVOLT ensures that your system is seamlessly integrated into professional market structures.
Through our digital infrastructure, your energy system is connected to the most relevant markets.
This works when system, control, and market access interact optimally:
Connection to a trading or market access platform is provided via TESVOLT Energy .
The entire market participation is fully automated:
With the TESVOLT Energy platform, you always have full visibility:

Don’t settle for just one market.
Cross-market participation combines two revenue streams in one system: the balancing services market and the wholesale market (e.g., EPEX Spot). This ensures that the available flexibility of the storage system is used optimally.
Your system always operates where the greatest economic value is created.
