MILAN, Italy – Sonnedix, a global renewable energy company with over 4GW of operating capacity, has expanded its Italian portfolio with the acquisition of five new projects in Sicily and Lazio, adding a combined capacity of 226MW.

These acquisitions mark a significant milestone in Sonnedix’s growth trajectory in Italy, where the company’s operating capacity now exceeds 800MW. With approximately 500MW currently under construction, Sonnedix is on track to achieve 1GW of operational capacity in the country by the end of this year. Looking ahead, the company’s development pipeline of around 1.1GW is expected to double its Italian capacity to 2GW within the next three years.

While Sonnedix has historically focused on solar, the company is broadening its portfolio across the renewable energy spectrum and investing in advanced energy storage solutions. Sonnedix has started the construction of its first Battery Energy Storage System (BESS) project in Italy, an 18MW /4H plant located in Sicily. The project will be co-located with a 70MW PV plant currently under construction. This investment underscores the continuation of Sonnedix’s hybridisation and optimisation strategy, delivering efficiency, flexibility, and value to customers.

Axel Thiemann, CEO of Sonnedix, commented:

“It's remarkable to see the growth we've achieved since entering the Italian market in 2010, when we operationalised Sonnedix’s very first solar plant – and these latest acquisitions are a testament to our long-term commitment to delivering clean, affordable, and reliable energy to customers. Looking ahead, our focus is on continuing to convert our pipeline, particularly exploring opportunities in battery storage and hybridisation. With our extensive knowledge of the Italian energy landscape, and long-term footprint in the market, we are well positioned for continued sustainable growth.”

Mario Volpe, Sonnedix’s Head of Growth for Southern Europe and Representative Director for Italy, said:

“These acquisitions mark a major milestone in our continued growth in Italy, and with a strong pipeline of projects currently under construction, we are accelerating towards our target of 2GW operational capacity by the end of 2028. As we grow, we continue focusing on developing battery energy storage solutions, and delivering a long-term, reliable, and 100% renewable, supply of energy to our customers.”
