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.
