CWP Romania’s Largest Solar Plant Studina Goes Live, Battery Storage Next

The Studina solar power plant has entered regular commercial operation, developer CWP Europe announced. With 174 MW of peak capacity, the project is currently Romania’s largest operating photovoltaic plant, although several bigger utility-scale developments are already underway. The next milestone for Studina is the addition of battery energy storage.

Studina to Produce 245 GWh a Year in Olt County

CWP Europe estimates the Studina photovoltaic plant will generate around 245 GWh annually—enough electricity to supply more than 122,500 Romanian households. The site is located in Olt county, southwest of Bucharest.

At 174 MW nameplate capacity, Studina has taken the top spot among Romania’s operational solar facilities, surpassing Econergy’s Rătești plant (155 MW).

Bigger Solar Parks Already in the Pipeline

Studina’s lead is expected to be temporary as Romania’s solar pipeline accelerates. Nofar Energy is constructing the 282 MW Corbii Mari solar park, while the investment arm of Sweden-based Ingka Holding—the world’s largest IKEA franchisee—is developing the 300 MW Butimanu PV project, with completion targeted for April 2027.

Meanwhile, Enery is preparing to start construction on a major project of 750 MW peak capacity near Bucharest, alongside several other large-scale developments in progress.

Battery Storage Next: Permit Secured for Co-Located System

CWP Europe said Studina has also obtained a building permit for a co-located battery energy storage system, with construction planned as the next phase. The company added that the project was built in partnership with Renalfa.

EPC Partners, Contractors and Equipment

CWP Europe credited its construction team and engineering partners for delivering the project safely and on schedule. Chief Financial Officer and Chief Operating Officer Alex Sekulovic said close coordination and disciplined execution—together with EPC partners Solarpro and Eximprod—helped ensure quality standards and compliance with EHS (environmental, health and safety) requirements, with zero accidents reported during construction.

Solarpro is part of the Austria-based Renalfa Solarpro Group. Siemens Energy was among the contractors, while LONGi supplied Hi-MO 7 bifacial solar modules.

CWP Europe Executive Vice President Viktor Garbev said the project highlights the company’s ability to secure sites, build partnerships, navigate permitting, and deliver assets at scale in demanding technical and regulatory environments.

Grid Connection and Ownership: China Huadian Has Minority Stake

According to recent Romanian media updates, Studina has a 134 MW grid connection, and Chinese state-owned China Huadian Corp. holds a minority stake in the project company.

Related Deal: CCE Sells Horia 2 Project to Renalfa Solarpro

In a separate transaction, CCE sold its Horia 2 solar project to Renalfa Solarpro Group in January. The planned facility is sized at 293.3 MW peak capacity with a 269.2 MW grid connection. Located in Arad county, the site covers 349 hectares.

Romania Nears 3.35 GW in capacity prosumers as residential solar catches up with business installations

Romania had nearly 290,000 prosumers by the end of November, with a combined installed capacity of 3.35 GW, according to the national energy regulator. While prosumer projects have been the main driver of the country’s solar expansion for years, utility-scale developments moved to the forefront in 2025. At the same time, the prosumer segment is showing a notable shift: residential capacity has effectively converged with installations owned by legal entities, including small companies and institutions.

In its latest update, the Romanian Energy Regulatory Authority (ANRE) reported 287,985 prosumers at the end of November, together accounting for 3.35 GW of electricity production capacity. That represents a sharp year-on-year increase of 47.8% in the number of prosumers and 43.4% in installed capacity. The comparison with previous years highlights the scale of the boom: Romania counted just 303 prosumers at the end of 2019, and the country crossed the 3 GW prosumer threshold in August last year.

Households nearly match legal entities in installed capacity

ANRE’s data also point to a narrowing gap between households and non-household prosumers. The number of residential prosumers reached 257,748, compared with 30,237 legal entities. Installed capacity was almost evenly split between the two categories: households held 1.67 GW, while legal entities accounted for 1.68 GW.

Energy storage deployment also continued to accelerate. ANRE said 58,012 prosumers had integrated batteries alongside their rooftop solar systems. Households represented 55,962 of those installations, meaning more than one in five residential prosumers had storage.

Industry estimate: solar capacity exceeded 7 GW in 2025

Separately, the Romanian Photovoltaic Industry Association (RPIA) estimated that Romania’s total installed solar capacity surpassed 7 GW in 2025. The association assessed net additions at 2.2 GW over the year, up from 1.7 GW in the preceding 12-month period.

RPIA attributed the strongest momentum to utility-scale projects, estimating they contributed 1.2 GW of new capacity—almost double the level recorded in 2024—largely supported by renewable energy auctions conducted under contracts for difference (CfDs). Prosumers added an estimated 1 GW. RPIA further said residential systems reached 1.8 GW by the end of last year, broadly in line with commercial and industrial (C&I) installations.

Looking ahead, RPIA projects new solar capacity in 2026 at 2.5 GW. If delivered, that pace would bring Romania to its 10 GW target for 2030 well ahead of schedule.

In wider regional developments, Turkey is preparing to allocate 3.5 GW of capacity for self-consumption in 2026. Energy and Natural Resources Minister Alparslan Bayraktar said recently that priority would be given to local authorities, public institutions, and strategic, export-oriented sectors.
