CWP Europe has achieved commercial operation at the 174 MWdc Studina solar plant in Romania, marking a significant step in the country’s renewable energy expansion. The facility, now the largest operational solar park in Romania, is projected to generate approximately 245,000 MWh of clean electricity annually, powering over 122,500 households and offsetting around 220,500 tonnes of CO₂ emissions each year. Built with advanced technology including bifacial modules and single-axis trackers, the project was delivered in collaboration with key contractors Siemens Energy, Solarpro, and Eximprod. A building permit for co-located battery storage has been secured, paving the way for future hybrid enhancements. This development underscores accelerating momentum in Southeast Europe’s solar sector amid broader energy transition goals.
Studina Solar Project Reaches Commercial Operation Date
CWP Europe has successfully brought online the Studina solar facility, a 174 MWdc photovoltaic installation located in Olt County, southwest of Bucharest. This achievement follows the project’s commercial operation date (COD), transforming what was once a development pipeline asset into a fully operational clean energy generator contributing directly to Romania’s grid.
Acquired by CWP Europe in 2023, the project advanced rapidly through construction phases, ultimately surpassing initial timelines that targeted end-of-2024 commissioning. The plant now stands as Romania’s largest operational solar park in terms of nameplate capacity at 174 MWdc, eclipsing the previous leader, the 155 MW Rătești facility developed by Econergy. While larger projects are in various stages of construction across the country, Studina’s entry into service represents a tangible milestone for utility-scale solar deployment in the region.
The facility employs high-efficiency bifacial solar modules mounted on single-axis trackers, paired with string inverters to optimize energy yield across varying irradiance conditions. This configuration enhances performance by capturing reflected light on the rear side of panels and allowing dynamic tracking of the sun’s path throughout the day. Such technical choices are increasingly standard in large-scale European solar developments, helping maximize output in temperate climates like Romania’s.
Annual energy production is estimated at around 245,000 MWh, a figure derived from site-specific solar resource assessments, system design efficiencies, and historical performance modeling. This output equates to supplying electricity to more than 122,500 average Romanian households, assuming typical per-household consumption patterns in the region. On the environmental front, the avoided CO₂ emissions—projected at approximately 220,500 tonnes per year—provide a substantial contribution toward national and EU decarbonization targets, displacing fossil fuel-based generation in the power mix.
Key contractors played instrumental roles in delivering the project on schedule. Siemens Energy provided critical electrical infrastructure and grid integration expertise, Solarpro handled engineering, procurement, and construction aspects with a focus on regional execution capabilities, and Eximprod contributed specialized components and systems integration. Their combined involvement ensured technical reliability, adherence to European standards, and efficient commissioning processes.
Looking ahead, CWP Europe has already secured a building permit for a co-located battery energy storage system (BESS). This forward-thinking addition positions Studina for hybrid operations, enabling energy shifting, grid stability services, and improved revenue potential through arbitrage and ancillary market participation. Construction of the storage component is slated as the next phase, aligning with growing trends across Europe where solar-plus-storage configurations address intermittency challenges and enhance overall system value.
The Studina project reinforces CWP Europe’s strategic footprint in Southeast Europe, where the company continues to build out a multi-gigawatt pipeline of wind, solar, and storage assets. Romania’s supportive regulatory environment, improving grid access, and attractive solar irradiation levels have positioned the country as a hotspot for renewables investment. With EU funds and national incentives accelerating deployment, projects like Studina demonstrate how private developers are driving the transition toward a cleaner, more resilient energy system.
