Sunly is investing 100 million euros in an energy park in Latvia

The Estonian renewable energy developer Sunly plans to invest approximately 100 million euros in a large hybrid energy park in northern Latvia. The project combines solar and wind energy with modern battery storage systems and is intended to strengthen the region’s energy supply. The Latvian news agency LETA reported on this on May 28.

For years, the Baltic states have been pursuing the goal of expanding their energy independence and reducing their reliance on fossil fuels and previous Russian energy imports. Hybrid energy parks are considered a key component of the energy transition.

Sunly is one of the fastest-growing renewable energy developers in the Baltic region. The company focuses on solar, wind, and storage projects in the Baltic states as well as in Poland.

Hybrid model with solar, wind, and storage technology

The project is being developed near Matīši in the municipality of Valmiera. The plan is to combine solar and wind power plants with battery energy storage systems (BESS) operated via a shared grid connection.

According to Sunly, the existing solar park already has an installed capacity of 54 megawatts. The facility produces enough electricity annually to supply approximately 15,000 households.

The company has now also received the necessary building permits for the expansion into a full-scale hybrid energy park.

Significance for Energy Supply in the Baltic States

The overall project could become an important addition to the energy infrastructure in the Baltic region. The region is increasingly investing in renewable energy to enhance its energy security and drive the energy transition forward. The official opening of the energy park is scheduled for June 4.

During the event, Sunly also plans to announce a partnership with the British technology group Rolls-Royce. The collaboration will focus on the development of battery storage systems. According to LETA, this could result in Rolls-Royce’s largest energy project to date in the Baltic region.
