SZE International Conference 2023 announcement

The Slovenian Energy Association (SZE) is pleased to announce the SZE International Conference 2023. Organised is collaboration with Resalta as the main sponsor, the event will be held in Grand Hotel Bernardin, Portorož, Slovenia, from 4 to 6 June 2023.

Conference focus: Energy efficiency and sustainable, secure, and accessible energy supply

In an age when the climate is changing rapidly, sustainable, secure, and accessible energy supply is a vital factor in improving people’s welfare and achieving global competitiveness. Energy efficiency measures are instrumental in attaining these objectives.

Collaboration and cooperation are essential to meet carbon-neutral targets. Drawing on the EU Commission’s guidance, the SZE International Conference 2023 will discuss possible practical applications of new technologies and showcase business model examples that are based on cooperation across sectors. It is only by working together that we can achieve the set goals and reach across disciplines, industries, and sectors.

You are kindly invited to join us for the SZE International Conference 2023 and help us turn vision into real projects.


As one of its main activities, the Slovenian Energy Association (SEA) organises the annual International Conference on District Energy. Until 2017, the conference had focused primarily on district energy and had been organised by the Slovenian District Energy Association (SDDE), now the SEA. Ever since its beginnings, the association has believed that the only way to achieve its goals is through organised meetings and discussions.

The first edition of the conference was held at the inception of the association in Zreče, Slovenia, in 1998. All the following conferences took place in the seaside town of Portorož, where the nice Mediterranean spring setting provides a perfect backdrop for a successful implementation of the formal as well as informal parts of the meetings. With interesting presentations and using international contacts of the association members, we have managed, year after year, to attract a growing number of eminent and acclaimed speakers from far and wide. The international character of the conference has grown increasingly prominent thanks to a number of returning guests from more than 12 European countries, whereas participants have also joined us from China and the U.S. The conference offers attendees ample opportunities to exchange their opinions and experience in order to increase the energy and economic efficiency in designing new energy systems as well as managing and maintaining the existing ones. The conference also provides a venue for the encounter of diverse perspectives and views, and a chance to engage in a constructive dialogue to arrive at best possible solutions.

The many district energy upgrades and new solutions implemented in Slovenia suggest that our collective endeavours with the past SDDE/SEA conference editions have contributed substantially to improved efficiency and security of energy supply in Slovenia. We are proud to say that the conference organised by the Slovenian Energy Association has become one of the main events in the heat and power sector not only in Slovenia, but also in the region of the former Yugoslavia. This inspires us to continue our efforts for further successful conference editions in the years to come.
