Key synergies and cooperation projects between ELES Group companies

Key synergies and cooperation projects between ELES Group companies


Custom-made auctions

We conduct custom-made auctions for the purchase of electricity in order to:

  • cover losses in the transmission network, and
  • perform tertiary frequency control.

Integration of power exchange markets

We run projects aimed at integration of the Slovenian power exchange market into a single European electricity market in the following segments:

  • day-ahead trading (at all borders of the Slovenian electricity system);
  • intraday trading (XBID project – developing technologies and procedures for the implementation of a single intraday market coupling).


Adapting the consumption

We manage our electricity consumption dynamically by:

  • responding to electricity grid demands and contributing to the stability of the transmission system;
  • supporting ELES as the transmission network system operator in case electricity flows need to be balanced due to grid instabilities.

FutureFlow Project

We participated in the pilot tests for demonstrating that prosumers can deliver high quality and flexibility services to the TSOs. An international research project was coordinated by ELES.
