LONGi, a global leader in solar technology and energy storage solutions, and Enexus, a Romanian developer and EPC contractor, have signed a landmark agreement for 50 MWh of liquid-cooled Battery Energy Storage Systems (BESS) in Titu, Dâmbovița County, Romania.
The agreement marks Enexus’s first deployment of LONGi’s advanced BESS technology. It represents one of LONGi’s largest BESS orders in Romania to date one of its most significant deployments in Europe.
The deployment comprises two distinct PV-plus-storage projects in Dâmbovița County, designed to support energy shifting, capacity firming, and broader grid-support functions:
- Titu 1, with an installed capacity of 20 MWp and 15 MWh BESS. The park was developed in partnership with Akış Enerji, part of the Ulusoy Enerji Yatırımları A.Ş. group. It is fully completed and is currently awaiting grid connection.
- Titu 3, with an installed capacity of 35 MWp and 35 MWh BESS. Developed for FTZ Group, the project is currently under development.
Speaking on LONGi’s integrated solar-plus-storage vision, Dennis She, Vice President of LONGi and President of LONGi Energy Storage, emphasized: “The next phase of the global energy transition demands a total departure from fragmented, multi-vendor systems. Energy storage is no longer just an add-on; it is an essential stabilizer of the modern power network. Historically, developers were forced to piece together PV panels, batteries, and conversion units from disparate suppliers, creating integration bottlenecks and blurred accountability. By combining our generation technology with fully integrated BESS architectures, we offer one coordinated, grid-ready ecosystem. Our milestone project with Enexus in Titu demonstrates how turnkey solar-plus-storage solutions maximize plant economics, streamline execution, and deliver true grid resilience.”
The two Titu projects demonstrate the benefits of combining high-efficiency solar generation with utility-scale storage within an integrated equipment ecosystem. The 50MWh deployment comprises 10 units of LONGi’s liquid-cooled utility-scale BESS solution, paired with integrated medium-voltage (MV) skid systems.
Detailing the strategic choice behind the technology selection, Mesut Güler, Founder and CEO of Enexus, stated: “Our partnership with LONGi reflects a strategic choice as much as a technical one. Integrated equipment means easier planning, faster delivery, and more predictable payment structures for our investors, while giving our clients access to Tier 1 PV technology. Integrating BESS in PV project design is a strategic direction we outlined since last year, and we are living up to this commitment – with LONGi entrusting us with one of its largest BESS projects in Romania so far. For us it is a clear signal of the trust and technical alignment behind this partnership.”
