Over the past 30 years, JUWI has planned and built more than 3,500 megawatts of wind energy capacity and over 4,000 megawatts of PV capacity worldwide – around 1,000 megawatts of renewable energies will be added in the coming months. With the start of module assembly at the Greek solar park Triffyli, JUWI has reached the milestone of one gigawatt of capacity, which will be installed simultaneously on its many construction sites worldwide.
“This once again demonstrates our competence in successfully planning and implementing challenging projects. Our construction activities are currently in full swing,” emphasizes JUWI CEO Jost Backhaus. In total, JUWI currently installs around 1.3 million solar modules in twelve PV projects and implements 46 wind turbines at eleven locations.
The “Trifylli” solar park in northern Greece, about 400 kilometers north of Athens, is part of the “Clover” PV portfolio that JUWI is currently building for the investor Mirova. The cluster consists of a total of four projects with a total capacity of 156 megawatts, all of which are to be put into operation next year at the latest. In total, JUWI is currently building PV projects with a total capacity of over 400 megawatts at seven locations in Greece. In Greece in particular, the construction workers repeatedly come across historical finds. “Our planning and implementation teams are challenged to develop flexible solutions in order to minimize delays and constant adjustments to the system configuration,” Backhaus continues.
JUWI employees are also working on the implementation of renewable energy plants on the African continent. The “Grande Cote Operation” PV hybrid park in Senegal, which is being built for the mining and metals company Eramet, is almost complete. Around 100 kilometers northeast of the capital Dakar, JUWI is building a 20.3 megawatt PV plant together with a battery storage system (capacity: 11.12 MW). The PV construction sites in South Africa, on the other hand, are still in full swing: a total of four projects with a total capacity of around 350 megawatts are currently being implemented.
While the international focus is on the PV business, in Germany wind energy is the main sales driver for the JUWI Group. JUWI is currently building a total of 46 wind turbines with a total capacity of around 270 megawatts at eleven locations (Brandenburg, Rhineland-Palatinate, Lower Saxony, Saxony-Anhalt and North Rhine-Westphalia).
In addition, planning for the next construction projects is also in full swing in the USA and Italy. JUWI is thus continuing its successful project implementation in both countries, after the company commissioned two larger PV projects at the end of 2025: One of the two US solar parks is Axial Basin Solar, a 186-megawatt project in Moffat County in northwestern Colorado, about 250 miles northwest of Denver. The second PV system in the USA is Dolores Canyon Solar. This solar park has a capacity of 141 megawatts and is located in Dolores County, about 400 kilometers southwest of Denver.
JUWI Energie Rinnovabili S.r.l. also commissioned two large photovoltaic projects last autumn. In Sardinia, JUWI employees have connected a 41.7 megawatt park to the power grid. Here, too, the challenges during the construction phase were high: To the surprise of everyone involved, archaeologists had found numerous remains of historic buildings during the construction supervision. These are likely to be parts of a settlement area that is around 6,000 years old, including churches and graves. The second Italian project is located about 70 kilometers south of Venice in Rovigo. In the case of the Loreo solar park, the construction engineers had to struggle less with archaeological challenges than with the soft soil in the coastal swamp area.
