State-owned electricity transmission operator Elektro-Slovenija (ELES) is introducing electricity sharing in Slovenia.

The concept, brought in following an amendment to Slovenia’s Electricity Supply Act, will allow owners of solar power plants to transfer excess energy produced to designated recipients via the grid.

“The purpose of this measure is to use surplus electricity produced by solar power plants more efficiently,”  a statement published by ELES explains. “Sharing also has a solidarity effect in addition to the balancing effect – for example, helping a relative, friend, or acquaintance.”

Electricity sharing in Slovenia is set to go live on July 1. In order to participate, ELES explains the sender and recipient of the electricity must enter into a legally-binding formal agreement on shared use and inform the relevant distribution operators and electricity suppliers.

Nina Hojnik, Director of the Slovenian Photovoltaic Association (ZSFV), confirmed to pv magazine that registration to the system opened on June 1 via the unified web portal Moj elektro.

“The conditions, such as price, sender and recipient(s), must be identified and mutually confirmed on the platform upfront,” Hojnik explained. “Energy sharing is available to all final electricity consumers, with the exception of large companies and entities for which participation in energy sharing would constitute an economic activity.”

Hojnik added that the amount of electricity shared, as well as its price, is agreed upon in advance on a 15-minute interval basis. The allocation can be modified monthly and cannot exceed 100% of the electricity produced by the sender. Any allocated electricity not used by the recipient will then belong to the supplier.

ELES’ guidance states the price relies entirely on the two parties and can be “completely symbolic”. An electricity sender can enter into an unlimited number of agreements with electricity recipients. The two parties in an agreement do not need to live near each other, the guidance adds, with the only stipulation being that both parties are located in Slovenia.

The electricity sharing system will also be available to those in Slovenia that installed residential solar under the country’s net metering mechanism, but only as a transmitter of electricity.

Net-metering participants that join the scheme will have any electricity allocated for sharing deducted from the total amount of electricity they export to the grid during each 15-minute settlement period. The annual net metering calculation of all received and transmitted energy will still be carried out, except the transmitted energy will be reduced by the amount supplied for energy sharing.

ELES guidance gives an example of a net metering producer that takes 7,000 kWh of electricity from the grid during a certain billing period, while sending 9,000 kWh of produced electricity to the grid. If the producer then allocates 1,000 kWh for shared use, they would have 1,000 kWh left in the given billing period, which will be taken into account as a surplus during billing.

Hojnik added that the introduction of electricity sharing should contribute to future solar deployment, as well as to the active consumption of electricity produced by solar power plants.

Slovenia deployed 146.5 MW of solar in 2025, taking cumulative capacity to 1.57 GW.
