Slovenia’s TSO ELES joins forces with army to develop hydrogen technologies

Slovenia’s transmission system operator ELES and the Ministry of Defence have signed a cooperation agreement for the Defence Resilience Hub Network in Europe – RESHUB project.

Last year, the Ministry of Defence of Slovenia initiated the Defence Resilience Hub Network in Europe (RESHUB) project, which aims to establish self-sufficient energy hubs in Slovenian military barracks.

As part of the initiative, the military barracks in Kranj will be transformed into a demonstration center for energy self-sufficiency, integrating military infrastructure with innovative solutions in renewable energy and hydrogen technologies.

Aleksander Mervar, CEO of ELES, and Marko Lovše, State Secretary of the Ministry of Defence, now signed the agreement, during the Slovenia-Japan Business Conference.

The deal outlines cooperation in the field of energy self-sufficiency and the development of hydrogen technologies, according to state-owned ELES.

The project will turn the Kranj military barracks into a demonstration center for energy self-sufficiency by integrating military infrastructure with innovative technology for renewables and hydrogen.

ELES will contribute to the development of the RESHUB (Resilience Hub) pilot project concept, which focuses on the production, storage, and use of hydrogen, the country’s TSO noted.

The company will be involved in all phases of the project — from preparing expert studies and technical groundwork to providing professional support for documentation development.

ELES considers hydrogen a potential key energy carrier for storing surplus energy from low-carbon sources

“At ELES, we recognize hydrogen as a potentially key energy carrier for storing surplus energy from low-carbon sources, which can later be reused in the energy sector, transport, and industry,” according to the company.

ELES recalled that in 2024 it established a consortium to build a hydrogen ecosystem based on low-carbon sources.

Collaboration with Japanese partners, who have been actively developing and, in some cases, successfully deploying hydrogen technologies for decades, is essential for the company. ELES has already established several partnerships with Japanese companies and is now exploring new opportunities for deeper cooperation in the further development and application of hydrogen technologies.

In recognition of Mervar’s outstanding contribution to strengthening bilateral economic and technological ties, Japanese Ambassador to Slovenia Akiko Yoshida awarded him an honorary recognition at the business conference.

Electricity prices for Slovenian firms among highest in EU in 2024

Last year, Slovenian households had cheaper electricity than the European Union average while the tariffs for other categories of consumers, including businesses, were among the highest in the EU, according to an analysis by Slovenia’s transmission system operator ELES.

The analysis, conducted by ELES CEO Aleksander Mervar, also showed network fees are significantly lower than the EU’s average.

Slovenia is in the bottom third of the list of the 27 member countries. As for its neighbors, domestic prices were higher than in Hungary and Croatia, and lower than in Austria and Italy, Naš Stik reported.

Last year, Bulgaria had the lowest prices in the EU, followed by Malta, Luxembourg, Hungary, and Croatia. When measured against purchasing power, prices in Slovenia are in the lower half of the list.

The Government of Slovenia has capped electricity prices for households

The analysis attributes the lower tariffs for households mainly to measures that the Government of Slovenia introduced. The two main interventions were setting a maximum price for 90% of consumption, and freezing the payment of a fee for subsidizing electricity production from renewables and high-efficiency cogeneration.

From January 1 to October 31, the maximum price was 8.2 eurocents per kWh in the lower tariff and 11.8 eurocents per kWh in the higher one. They were the maximum prices for 90% of consumption, while the remainder was set by suppliers in line with the market conditions.

Without government measures, the annual bill of the average Slovenian household, with an annual consumption of 4,000 kWh, would be higher by EUR 345.89 or 45.77%, according to the calculation.

ELES denies network fees impacted competitiveness of firms

The conditions for businesses were different. Prices for commercial and industrial consumers were among the highest in the EU. However, the domestic average was lower than in neighboring countries.

Businesses in Serbia experienced a similar issue last year.

ELES denied the claim by the Chamber of Commerce and Industry of Slovenia that high network fees lowered corporate competitiveness. The company argued they were significantly lower for commercial consumers, by 36.5% to 49%, than the EU average.

In addition, network fees are as much as 53% below the level in the countries surrounding Slovenia, according to the ELES analysis.

Network fees for households in Slovenia are among the lowest in the EU.
