Solar and wind power projects with or without energy storage that are on Slovenia’s priority list can be submitted for grants from the European Union’s Modernisation Fund. The round is worth EUR 29.5 million and the deadline is January 7. Notably, of the 1,117 projects for renewables and cogeneration approved for state support so far, only 254 were completed by the end of 2024.

The Ministry of the Environment, Climate and Energy launched a public call for cofunding under a mechanism for the modernization of energy systems in Slovenia and improvement of energy efficiency. It is for projects for solar and wind power plants, with or without storage, from the so-called A list of indicative, priority investments.

Eligible companies can receive support from the EU’s Modernisation Fund under the RES Scheme (Part A). It was approved by the European Investment Bank. The list was published in March of last year.

Total planned support amounts to over EUR 84 million and the selected projects must be completed by the end of September 2030. The deadline for submissions in the current round is January 7, 2026.

The grants can cover up to 45% of the costs for photovoltaic and wind power systems and a maximum of 30% of the electricity storage segment, the documentation shows. Storage capacity must be at least 0.75 kWh per kW of the nominal capacity of the power plant.

All five eligible projects are within state-owned HSE Group

There are 21 items on the A list and most are power grid investments. Only five are for renewables, of which Dravske elektrarne Maribor (DEM) is present with its controversial Ojstrica wind farm project, the proposed expansion of the Zlatoličje-Formin solar park, and the ZOOP photovoltaic project for 9.9 MW in peak capacity on the former Pobrežje waste landfill.

The largest priority investment among the ones that can apply in the current round is HSE’s proposed floating PV plant with batteries

The company is part of state-owned Holding Slovenske elektrarne – HSE. Another subsidiary on the list, Soške elektrarne Nova Gorica (SENG), intends to expand its recently commissioned Kanalski Vrh solar power plant.

HSE itself has the largest project – for the Družmirje floating solar power plant, which would include storage. It also plans to produce green hydrogen using electricity from the facility.

Few completed energy production projects among ones selected through public calls

The Energy Agency of Slovenia has so far approved 1,117 renewables and cogeneration projects to enter the support scheme, selected through 13 public calls. The combined planned capacity is 794 MW, of which there were 996 renewable energy projects, for 682 MW.

However, only 254 endeavors, with 112.6 MW altogether, were completed by the end of last year. In the previous round, the agency selected 507 projects, for a total nominal capacity of just over 259 MW, mostly for PV plants.

Of note, lengthy procedures, strict environmental rules and local opposition are keeping Slovenia at the bottom of the European Union’s wind power capacity chart in the European Union. The country hosts just three standalone wind turbines and DEM has contracted the fourth one.
