LONGi Solar Europe and independent power producer Enery have announced a strategic alliance that positions the Chinese solar manufacturer as the primary technology provider for up to 50 percent of Enery's 1.5-gigawatt project pipeline scheduled for delivery in 2026 and 2027.

The partnership is anchored by the Ogrezeni hybrid mega-project in Romania, a 761 megawatt-peak solar installation paired with more than one gigawatt-hour of battery storage that stands as one of Europe's largest hybrid renewable energy facilities.

A Pipeline Built for Regional Scale

Enery's 1.5 GW development pipeline across Central and Eastern Europe has created the foundation for what both companies describe as a historic phase in their relationship. LONGi is actively working to serve as the primary technology provider across 50 percent of that pipeline, establishing a supply relationship that spans multiple markets in the region.

Leon Zhang, President of LONGi Europe, framed the arrangement as a convergence of Enery's regional ambitions and LONGi's manufacturing capability. "Enery's massive pipeline for 2026/2027 reflects their incredible regional leadership, and LONGi is proud to be working closely with them on this pipeline with our advanced technology," Zhang said. "The Ogrezeni mega-project is a blueprint for the future of European energy, combining giga-scale solar with massive energy storage."

Ogrezeni: Romania's Landmark Hybrid Project

Construction has officially commenced at the Ogrezeni site in Giurgiu County, Romania, where Enery is developing the flagship project of its current pipeline. The facility combines a 761 megawatt-peak solar photovoltaic array with more than one gigawatt-hour of battery energy storage, a configuration that developers say qualifies it as one of Europe's largest hybrid renewable energy projects.

The project is backed by USD 496.8 million in syndicated green financing and has received support from the Three Seas Initiative Investment Fund, known as 3SIIF. At peak construction, the project is expected to create 350 jobs.

LONGi will supply 1,167,120 of its Hi-Mo 9 Back Contact modules to the site. Alberto Martinez, Head of Construction and Operations and Maintenance at Enery, said technology selection was central to the project's execution strategy.

"Implementing LONGi's product Hi-Mo 9 BC technology with 660W peak power ensures our asset achieves industry-leading efficiency and energy yield," Martinez stated. He also highlighted the role of LONGi's local partner team in providing engineering and logistical support throughout the construction process.

Tripartite Structure Anchors Local Supply Chain

To connect international technology with local delivery, Enery brought in Romania's ENEVO Group as the main Engineering, Procurement, and Construction contractor.

This three-party arrangement between Enery, LONGi, and ENEVO is designed to strengthen national supply-chain resilience by sourcing core engineering, construction, and materials domestically.

Cristian Pîrvulescu, Chief Executive Officer of ENEVO Group, said the project demonstrates that Romanian engineering has reached a level of maturity capable of executing infrastructure at this scale. "Integrating 1.16 million LONGi Hi-MO 9 modules with a massive 1 GWh battery storage facility requires precise engineering, strong execution capabilities, and a robust logistical backbone," Pîrvulescu said.

"For us, this project is a clear confirmation that Romanian expertise can play a valuable role in delivering complex renewable energy infrastructure to European standards."

Hi-Mo 9 Technology at the Core

The Ogrezeni installation relies exclusively on LONGi's Hi-Mo 9 module, which is built on the company's proprietary HPBC 2.0 cell architecture, which stands for Hybrid Passivated Back Contact. The module delivers up to 660 watts of peak power and carries an efficiency rating of up to 24.8 percent, which LONGi describes as industry-leading.

The module features a front-side Zero Busbar design, referred to as 0BB, which the company says optimizes light absorption and allows more power to be generated from a smaller surface area. LONGi states that this configuration significantly lowers Balance of System costs and maintains an ultra-low linear degradation rate across a 30-year lifecycle.

Mirel Jarnea, Country Manager Romania at LONGi Europe, described the Ogrezeni deployment as a historic moment for Romania's energy sector, though the full text of his remarks was not available in the source material provided.

Green Financing and Regional Investment Framework

The USD 496.8 million syndicated green financing package underpinning the Ogrezeni project reflects a broader investment framework that includes participation from the Three Seas Initiative Investment Fund.

The Three Seas Initiative is a regional platform focused on infrastructure development across Central and Eastern European countries. The fund's involvement in the Ogrezeni project signals institutional backing for large-scale hybrid renewable energy development in the region.

The combination of private project financing, multilateral investment support, and a tripartite contracting structure positions Ogrezeni as a model that both LONGi and Enery intend to replicate across the broader 1.5 GW pipeline in the coming years.

Powering Your Pipeline: Intelligence That Keeps Europe's Energy Sector Within Reach

Across Europe, the race to modernise power infrastructure is accelerating at a pace that leaves little room for guesswork. Whether you are tracking grid expansion programmes, renewable energy mandates, or cross-border transmission investments, the difference between winning work and missing it often comes down to how early and how accurately you see what is coming.

The Global Project Tracking (GPT) platform by Blackridge Research is purpose-built for professionals who cannot afford to rely on fragmented data sources or delayed reporting. It brings the full landscape of European power sector activity into a single, structured intelligence environment, giving your business development and strategy teams a genuine competitive edge.

From offshore wind developments in the North Sea to grid modernisation schemes in Eastern Europe, the platform continuously monitors project movement so you are never caught reacting when you should have been preparing.
