Acciona Energia, a prominent Spanish renewable energy firm, has commenced construction on what is anticipated to be the largest solar power facility in Croatia and the surrounding region. The Promina project, situated in Šibenik-Knin County, marks a significant step in the country’s transition towards renewable energy sources. Initial activities began in early January, focusing on site clearing and land preparation across a substantial area designated for the solar installation.
The Promina project is being executed through Acciona’s Croatian subsidiary and is strategically located within the municipality of Promina. Upon completion, this solar power plant is expected to achieve a capacity of 150 MW, positioning it as the largest solar installation not only in Croatia but also in neighboring countries. The anticipated timeline for project completion is set for summer 2027, with total investments estimated to reach around 120 million euros. The facility is projected to generate approximately 274 GWh of electricity annually, which would be sufficient to meet the energy demands of about 69,000 households.
The solar facility will encompass two distinct locations. The southern site will cover about 162 hectares and will host photovoltaic modules with a total capacity of 90 MW. Meanwhile, the northern site will span approximately 122 hectares, contributing an additional 60 MW of installed capacity. This division into two locations underscores Acciona’s commitment to optimizing land use while maximizing energy output.
A critical component of the project involves establishing a robust grid connection through a newly constructed 400 kV Promina substation. This substation will be built under a turnkey contract awarded to Končar, valued at 15.3 million euros. The contract covers comprehensive construction and integration services for the substation, which will link to existing Konjsko and Velebit substations via a new 400 kV transmission line. Notably, this development will mark the first substation of this voltage level constructed in Croatia since 2004, highlighting its significance in enhancing the country’s energy infrastructure.
The Promina project represents not only a substantial investment in renewable energy but also an important step towards achieving regional sustainability goals. As Croatia continues to advance its renewable energy capabilities, projects like Promina are essential for meeting future electricity demands while reducing carbon emissions.
