Enexus has signed an EPC (engineering, procurement and construction) agreement with Compeador Construct, part of the Turkish-backed Astor RO Energy, to develop a large-scale solar power project in Alba Iulia, Romania. The facility is planned with an installed capacity of approximately 75 MW. The agreement covers both the generation scope and associated grid connection works described by the developer.
220 kV substation and grid integration scope
Alongside the photovoltaic plant, the project includes construction of a new 220 kV transformer substation. The substation will be equipped with two 80 MVA transformers. Enexus said the transmission infrastructure is intended to support efficient integration into Romania’s national transmission system and to enhance grid stability.
Construction is already underway in an initial phase, covering solar generation infrastructure and high-voltage connection systems required for grid integration. The development approach combines power generation assets with critical transmission infrastructure from the outset.
Substation engineering focus as renewables expand
Enexus stated that the project reflects a broader transformation in renewable energy development, where new installations increasingly require strong integration with transmission networks and advanced system-support capabilities. The company emphasized that substation engineering and grid connection expertise are becoming essential as renewable penetration rises and system flexibility becomes more important.
Representatives of Astor RO Energy, the Romanian arm of Turkish group Astor Enerji, highlighted Romania as a strategic market within their regional expansion plans. They said long-term sector growth depends heavily on development of robust energy infrastructure.
Cross-border investment and regional expansion plans
Enexus executives also pointed to Romania’s growing attractiveness for cross-border energy investment. They argued that well-structured projects with strong grid integration and operational resilience could support broader regional expansion in the renewable energy sector.
