Romania installs 2.2 GW of new solar capacity in 2025

Romania connected 2.2 GW of solar PV in 2025, according to figures from the Romanian Photovoltaic Industry Association (RPIA), marking the third consecutive year of growth in the country’s solar market. Total installed capacity has now passed 7 GW, with around 1.8 GW each in the residential and commercial & industrial (C&I) segments, and roughly 3.5 GW in utility-scale projects.

Of last year’s additions, about 1 GW came from prosumers, with the remaining 1.2 GW delivered by large-scale solar plants. RPIA policy director Irene Mihai said deployment in the residential and C&I segments continued to be driven by upfront subsidies financed through the National Recovery and Resilience Facility and the Modernisation Fund, while the 2022 energy price crisis cemented solar’s role as a “cost-effective and competitive hedge against volatility.”

Utility-scale growth accelerated sharply, with 1.2 GW installed in 2025—almost double the 613 MW added in 2024. Mihai attributed this to projects launched in 2023–2024 reaching completion under a more streamlined development framework, as well as the first contracts-for-difference (CfD) auction in 2025, which awarded 1,488 MW of solar across 26 projects.

Based on the current pipeline, RPIA believes Romania is on course to surpass its 10 GW solar target by 2030 set in the National Energy and Climate Plan. Mihai expects around 2.5 GW of new capacity to be added in 2026, split between prosumers and utility-scale plants, but warned that maintaining momentum will require fine-tuning the regulatory framework. Key issues include Romania’s planned first-come, first-served capacity allocation for tenders, the need to align primary and secondary legislation for operational licensing so new plants can sell power immediately after commissioning, and ensuring smooth implementation of guarantees of origin as the country moves from observer status in AIB (from 2025) to full membership by January 2027.

Romania’s PPA market has already seen 29 deals signed—15 solar, 12 wind, and two hybrid projects—but Mihai noted that limited tradability of guarantees of origin is still constraining the pool of offtakers. Further alignment with the European Energy Certificate System is seen as crucial to unlocking more long-term corporate offtake and supporting the next wave of solar investment.
