Direct marketer interface

Lucrative use of surplus battery capacity

The direct marketer interface enables the facility operator to offer their electricity through a marketer. This is much more lucrative than the feed-in tariff and is compulsory e.g. in Germany from an installed capacity of 100 kW.

How you benefit

  • Cost savings, since demand is covered by the storage system
  • Earn money through direct marketing
  • Doesn’t require a great deal of effort or high investment costs

How does it work?

The TESVOLT Energy Manager can communicate with the remote control unit of the virtual power plant (e.g. next-kraftwerke). All the relevant data is transmitted to this power plant’s interface in real time, allowing it to act as a marketer and, for example, regulate the output. The user can therefore get involved in energy services with their battery storage system.


In the case of direct marketing, the electricity generated by renewable energy installations is no longer remunerated through the feed-in tariff. Instead, it is marketed on the electricity exchange by a direct marketer. This can generate attractive additional revenues. Direct marketing is even mandatory for new installations with an installed capacity of 100 kW or more and commissioned in Germany after 1 January 2016.
