Romania's 761 MW Ogrezeni solar farm is not the largest project LONGi has ever built, that distinction belongs to utility-scale farms in China, but it represents something more structurally significant: a Chinese solar manufacturer betting €460 million in syndicated green financing on Eastern Europe as its next core market, not as a dumping ground for excess capacity. On June 22, 2026, LONGi announced it will supply more than 1.1 million of its Hi-MO 9 back-contact modules to independent power producer Enery's sprawling renewable pipeline in Central and Eastern Europe, with the Ogrezeni project in Romania as the flagship deployment. The facility pairs 761 MW of solar with over 1 GWh of battery storage and is scheduled to commission in 2027. That storage pairing is the tell: LONGi is not just selling modules. It is selling a regional architecture.
The Ogrezeni project arrives with unusual specificity about its engineering spine. LONGi's Hi-MO 9 modules use the company's proprietary Hybrid Passivated Back Contact (HPBC 2.0) cell technology, hitting 24.8% conversion efficiency at 670 W peak power per module, gains that matter when you are financing €460 million and need to defend per-megawatt costs against both European and American competitors. The battery storage (1 GWh) is sized not for grid arbitrage but for solar curtailment elimination, a problem that accelerates as CEE grids saturate with intermittent generation. Enery partnered with Romania's ENEVO Group as the main EPC contractor, anchoring engineering and construction locally while LONGi controls the technology pathway. That structure, Chinese module technology, European capital, local construction labor, is becoming the template for CEE solar. The Three Seas Initiative Investment Fund (3SIIF) co-financed the syndicated green facility, which speaks to the political envelope: Brussels and Warsaw see this project as infrastructure resilience, not commercial power generation.
What makes the capital figure material is what it unlocks downstream. As of early 2026, Enery operated 566 MW of installed capacity with 213 MW under construction, and holds a development pipeline of nearly 10 GW across 10 countries. LONGi is positioned as primary technology provider for roughly half that pipeline across 2026 and 2027. That is not a single-project win. That is a foothold that compounds. Once LONGi modules and specifications dominate Ogrezeni, they become the baseline for the next Enery projects in Poland, Hungary, Czech Republic, and the other CEE targets. European module manufacturers, SMA, Meyer Burger, even domestic Polish and Hungarian competitors, now face a Chinese competitor that is not competing on price alone but on capital deployment, project financing, and installed regional capacity. LONGi's President for Europe, Leon Zhang, framed it plainly: 'The Ogrezeni mega-project is a blueprint for the future of European energy combining giga-scale solar with massive energy storage.' That is not a description of one facility. That is a playbook for ten.
The implication cuts both ways. For grid operators in CEE, LONGi's presence lowers capital cost per megawatt, €460 million for 761 MW plus storage is credible at roughly €604 per kilowatt, in line with global utility-scale benchmarks and cheaper than many European-only projects. For European module makers and their supply chains, it signals market concentration in favor of Chinese manufacturers who can move capital faster and absorb lower financing costs. For Enery and similar independent power producers in the region, LONGi's commitment means they are no longer dependent on spot-market module pricing; they are tapping into global capital flows and technology parity directly. The risk: if Ogrezeni underperforms or faces grid integration delays in 2027, it becomes a proof point that Chinese-sponsored infrastructure hits headwinds in Europe, and LONGi's entire CEE strategy resets.
Watch three specific markers. First: Ogrezeni's actual commissioning in 2027 and the measured performance of that 1 GWh battery integration with the 761 MW array. Grid operators will examine curtailment rates and revenue stability before bankrolling similar projects. Second: whether LONGi's module pricing for Enery's remaining 1.5 GW pipeline holds or compresses as European competitors respond and Chinese financing becomes less favorable. Third: regulatory outcomes in Poland, Hungary, and Czech Republic around local-content rules and tariff treatment of Chinese solar imports, political pressure on CEE governments to favor European supply chains could disrupt LONGi's 10-country foothold before it hardens into market dominance.
