Investing in Croatia solar battery storage Solutions
Croatia is taking another significant step in its green energy transition. The national power company, Hrvatska elektroprivreda (HEP), has officially launched a call for bids for the construction of the Sukosan solar power plant, a major project that notably includes the option for a large-scale battery energy storage system. This development signals a clear commitment to modernizing the country’s energy infrastructure and embracing technologies that enhance grid stability and renewable energy integration.
The tender, published on the European Bank for Reconstruction and Development (EBRD) procurement platform, outlines a project with substantial capacity, set to become a key asset in Croatia’s renewable portfolio.
Project Details: A Closer Look at the Sukosan Solar Plant
The Sukosan project, officially known as PVP Sukosan, is designed with a forward-thinking approach that pairs solar generation with energy storage. According to the tender notice, the key specifications include:
- Installed Power: 56 MW
- Connecting Power: 45 MW
- Battery Storage: An optional but significant internal battery energy storage system with a capacity of up to 200 MWh.
The inclusion of a 200 MWh battery system is particularly noteworthy. This component would allow the plant to store excess energy generated during peak sunlight hours and dispatch it later, during periods of high demand or low solar output. This capability is crucial for ensuring a reliable power supply, stabilizing the grid, and maximizing the value of the solar energy produced.

Tender Process and Key Dates
The procurement is being managed as an open, two-stage tender process, beginning with an Invitation for Prequalification. This initial phase allows HEP to vet potential contractors based on their experience and capability to handle a project of this scale.
All official documentation and submissions are being handled through the EBRD’s Electronic Procurement for Projects (ECEPP) platform. Interested parties should take note of the following key details:
- Notice Type: Invitation for Prequalification
- EBRD Project ID: 56674
- Publication Date: March 31, 2026
- Closing Date for Prequalification: May 12, 2026, 20:00 UK time
Companies interested in participating must register on the ECEPP portal to access the full tender documents and submit their Prequalification Questionnaire (PQQ).
The Bigger Picture: Croatia’s Green Energy Ambitions
The Sukosan solar plant is more than just a single project; it’s a clear indicator of Croatia’s strategic direction in the energy sector. By pairing large-scale solar generation with battery storage, HEP is investing in a resilient and flexible grid that can accommodate a higher share of intermittent renewables.
This project aligns with both national energy goals and the European Union’s broader climate objectives. As Croatia continues to diversify its energy mix away from fossil fuels, projects like Sukosan will be instrumental in building a sustainable and secure energy future. For contractors and technology providers in the renewable energy sector, this tender represents a prime opportunity to contribute to a landmark project in one of Europe’s promising solar markets.
