In Romania, Enery is currently constructing one of Europe’s largest and most advanced hybrid plants for renewable energy. The project in Ogrezeni is setting new benchmarks for solar photovoltaics and battery storage across the CEE region in many different respects.
Strategic Impact: Building a Milestone for Romania’s Energy Transition
Approximately 762 megawatt peak of installed capacity. Over 1 gigawatt hour of storage capacity. Upon commissioning, a new green energy hybrid plant constructed by Enery in Ogrezeni, southeastern Romania, will be a milestone in the country’s decarbonization and energy security goals. Situated in the district of Giurgiu, the project is setting new benchmarks for scale, local value creation and technological integration even during its development phase.
Flagship Project: Local Value Creation and Full-Scale Execution
Turning a project of this magnitude from a blueprint into reality is a huge challenge. Official construction began in March 2026 in partnership with the Enevo Group, a Romanian EPC provider. Consequently, the entire development – photovoltaic (PV) plant, grid connection and battery energy storage system (BESS) – is being built entirely within the local value chain. And by tapping into regional engineering and construction expertise, the project also successfully bypasses many typical global supply chain bottlenecks. The on-site teams are driving an incredibly ambitious schedule, targeting completion and energization for the second quarter of 2026.
Manuel Maier, Enery’s Project Manager for Ogrezeni, explains the operational realities on the ground: “Project Ogrezeni is our flagship project not only on paper but also in execution – we will construct the PV plant using high-quality equipment from leading suppliers in the industry, bringing together a team of execution experts and working with proven and experienced partners.”
Construction works for the Ogrezeni project started in May 2026.
Technical Specifications of the Ogrezeni Hybrid Plant
Logistical coordination across such a vast area is exceptionally demanding. As Maier explains, “Despite its size and the allocation on 24 clusters over almost 1,000 ha, one of the main challenges will be to coordinate all workstreams throughout construction towards energization.” He adds, “The definitive highlight of this project will be to see the 400 kV grid infrastructure with its two 300 MVA power transformers and the co-located BESS of over 1,000 MWh come alive for the first time.”
The site combines large-scale solar generation, battery storage and high-voltage grid infrastructure in one integrated hybrid plant.
Community Impact: Local Benefits Beyond Green Electricity
A cornerstone of Enery’s project philosophy is the firm belief that the energy transition must deliver tangible benefits for the local people and environment. Therefore, the project in Ogrezeni represents much more than just a source of green electricity. To foster inclusive, equitable and diverse communities, early social initiatives have already involved renovating the local football pitch at the Aurel Solacolu secondary school, for example. Additional planned measures include installing local community PV systems to ensure that immediate neighbours can also directly enjoy the advantages of solar power.
Furthermore, the Ogrezeni project places a strong emphasis on long-term sustainability education. Enery plans to launch educational programmes at primary and secondary schools, covering topics such as renewable energy, general health and safety – with a specific focus on road and traffic safety – as well as biodiversity.
Biodiversity, Renaturation and Agri-PV Potential
From an ecological standpoint, the entire site is designed to harmonize with the local ecosystem. Thus, Enery is evaluating a biodiversity and renaturation strategy, which should incorporate systematic monitoring campaigns alongside an ambitious habitat restoration project aimed at achieving long-term positive effects for local species. Exploring innovative concepts for dual land use, Enery is also assessing an Agri-PV pilot project that combines agriculture with solar generation to maximize land utility without displacing local farming traditions.
Green Financing and Regional Energy Security
Backed by a €460 million green financing package recently concluded with a consortium of international banks, Ogrezeni represents a massive leap forward for regional energy security and the modernization of the power grid.
