Ljubljana – With the new year, changes in cross-border electricity trading will be implemented in the EU. The time window in which participants in the cross-border trading market can balance their portfolios within the day will be extended. This is expected to have positive effects on the market and the electricity supply. According to the announcement of the power grid operator Eles, Slovenia will introduce the novelty already in January.

The European Union Agency for the Cooperation of Energy Regulators (Acer) followed the proposal of the European transmission system operators with these changes, which it approved in mid-December.

The agency, headquartered in Ljubljana, expects that the change will contribute to better integration of flexibility services and renewable sources with rapidly changing production, while at the same time helping system operators maintain balance in the system and thus a reliable electricity supply.

Many European system operators have requested a postponement of the introduction of this change, but according to Eles, Slovenia will introduce it already in the first wave in mid-January. It will be introduced at the same time in Italy, Austria and Croatia, which means that the new rules will immediately apply to the exchange of electricity with most of Slovenia’s neighbors.
