    Romania is entering a phase where renewable capacity alone is no longer enough; the market now rewards projects that deliver predictability, flexibility and rapid operational stability. Enexus — acting simultaneously as developer, EPC and long-term operator — approaches this moment with a model built to reduce complexity, shorten the path from commissioning to full performance, and give investors the confidence to scale. As the company prepares to deliver more than 150 MW of new renewable and hybrid assets next year, its leadership underlines that the transition between construction and stable operation is no longer a purely technical milestone, but a decisive business advantage in a grid that is becoming more congested and more closely regulated.

    Against this backdrop, Enexus places early-stage storage integration, revenue-stacking readiness and insurance alignment at the centre of its strategy. The company argues that hybrid PV+BESS assets will reshape profitability, risk modelling and investor expectations across the region — and that Romania’s market must adapt quickly. By combining engineering, procurement, execution, O&M and investor support under one coordinated structure, Enexus aims to turn uncertainty into bankable outcomes and help define the standards for the next generation of renewable infrastructure in Romania.

     

    Enexus aims to deliver over 150 MW of installed renewable + storage projects next year in Romania. Given your dual role as developer + EPC + operator, what are the principal operational challenges you expect between the commissioning phase and full ramp-up of new capacity?

    One of the main challenges will be managing the transition from construction to operations, particularly ensuring that EPC contractors, grid operators, and off-takers are fully aligned during performance testing and data validation.

    Another priority is establishing robust monitoring, diagnostics, and predictive maintenance capabilities from day one to secure high availability, reduce curtailment risk, and stabilize performance throughout the ramp-up period.

    From a broader perspective, this phase is also where investor expectations and technical realities must converge. Romania is entering a stage in which the grid is becoming more congested and regulatory scrutiny is increasing, so the ability to deliver stable output early is not just an engineering challenge — it’s a business advantage.

    As an investor-first EPC, Enexus sees this ramp-up window as the moment when trust is validated. The sooner a project reaches predictable performance, the faster investors can scale their portfolios. This is why our model integrates EPC, O&M and investor support from day one: to reduce complexity, shorten reaction times and ensure a smooth path from commissioning to full profitability.

     

    With a contract for a 20 MWp solar park in Dâmbovița County, how do you assess the local supply-chain, construction cost escalation and land/permitting risk in Romania right now — and how are you planning to mitigate these risks?

    Romania still faces pressure on construction materials, logistics, and skilled labor, all of which can affect EPC timelines and costs. Land and permitting processes remain lengthy, especially regarding environmental procedures and grid-connection approvals.

    We mitigate these risks through early-stage due diligence, framework agreements with key suppliers to secure pricing and delivery, and proactive coordination with authorities to anticipate documentation requirements well ahead of execution.

    At industry level, Romania remains an attractive but demanding market: investor appetite is high, but consistency in execution is what differentiates the strong players. Enexus has learned that high-performing projects rely on disciplined preparation and long-term partnerships with suppliers who can match our standards of speed, reliability, and transparency.
    For foreign investors entering Romania, these risks are often amplified by a limited understanding of the local environment. Part of Enexus’ role is to translate this complexity into clear, predictable steps — turning uncertainty into bankable project pipelines.

     

    As you scale up, how are you integrating battery storage or hybrid solutions (for example coupling rooftop, ground-mounted PV with BESS) in your roadmap? What trends in revenue stacking, ancillary services or flexibility markets in Romania are you considering to future-proof your business model?

    A solar project without integrated storage loses technical flexibility and limits financial optimization. Our strategy is to maintain full readiness for large-scale deployment once the regulatory framework for storage and flexibility services matures in Romania. We are actively evaluating multiple revenue-stacking opportunities, capacity, balancing, peak shaving, and ancillary services for both co-located and standalone BESS assets.

    Hybrid projects are becoming the new frontier of competitiveness in the region. And one of the strongest signals from the Türkiye–Romania Energy Forum that Enexus organized, was exactly this: storage is becoming the defining trend shaping the next investment cycle. Turkish investors, European developers and regional utilities all expressed the same expectation: projects must deliver flexibility, stability and long-term value, not just installed MW. This shift is essential for Romania as well. Storage will shape profitability windows, investor confidence, and the grid’s ability to integrate new renewable capacity at scale.

    For us, the BESS roadmap goes beyond being a technical upgrade, it’s a strategic evolution of our model. Integrating battery storage aligns perfectly with what investors expect from us: speed, predictability, and long-term asset performance. The players that master storage integration early will define the next decade of renewable development in Romania.

     

    How aware are local developers and EPCs of the specific technical and operational risks associated with BESS projects during the early design and construction stages?

    Local developers and EPCs are still maturing in their understanding of BESS-related technical, operational, and financial considerations. The biggest challenge is structuring viable business models within an evolving regulatory landscape, while keeping pace with rapid changes in technology and cost structures. There is broad recognition of the strategic value of storage, but further legislative clarity is essential to enable robust financial modeling.

    At market level, storage is currently where solar was ten years ago – high potential and limited practical implementation. Enexus’ cross-market exposure (Turkey, Italy, Romania, Ukraine) gives us a comparative advantage in anticipating risks early and educating stakeholders on what bankability truly requires. This advisory layer is increasingly valued by investors who want clarity in a sector still finding its regulatory shape.

     

    How do project stakeholders currently address insurance as a prerequisite for bankability, and what are the main gaps in understanding between developers, financiers, and insurers?

    Insurance remains one of the most critical yet least clearly understood elements of bankability. Divergent technical assumptions and risk perceptions between developers, lenders, and insurers often create bottlenecks during financial close. Greater alignment on technical standards, testing protocols, and risk allocation would help streamline financing and reduce uncertainty.

    In our experience, insurance is a defining element of investor trust. With more capital flowing into hybrid and utility-scale projects, lenders and insurers need clearer frameworks, standardization, and harmonized risk assumptions.

    Enexus often acts as an interpreter between parties, translating technical realities into financial language and aligning expectations. This reduces friction and accelerates time-to-financial-close, a metric that investors value deeply.

     

    What challenges have you seen when applying traditional insurance products to battery energy storage projects, and how could these be better aligned with real project risks?

    Traditional insurance products are often difficult to apply to BESS projects because the policies were not designed around battery-specific risks, performance characteristics, or degradation patterns. This misalignment introduces uncertainty for both underwriters and investors. Tailored insurance solutions that incorporate battery performance metrics, degradation modelling, and operational conditions would significantly improve risk assessment and coverage suitability.

    As pioneers of early BESS deployment in Romania, we see this as an opportunity: insurers need better data, and developers need clearer guidance. Enexus is working to close this knowledge gap by adopting international best practices, collaborating with specialized underwriters, and collecting high-quality performance data from our hybrid assets.

    How do co-located PV+BESS projects reshape insurance needs, and to what extent are Romanian companies ready to assess and model this new risk profile?

    Hybrid PV+BESS configurations introduce a combined risk profile that spans both generation and storage technologies. Romanian insurers and technical consultants are beginning to recognize these complexities, but advanced modelling tools and targeted education are still needed to properly assess hybrid system risks.

    Hybridization changes everything: design requirements, operational procedures, risk profiles, and ultimately investor expectations. As a result, insurers are adapting, but developers must take part in the conversation, have a role in educating the market and building a risk framework where hybrid assets become easier to insure, finance, and scale.

     

    What are the key on-site and integration risks developers should anticipate when deploying BESS alongside generation assets?

    Developers should anticipate challenges related to grid integration, SCADA and communication system compatibility, and real-time coordination between PV and BESS assets. Given that grid operators have limited experience with hybrid systems, connection and testing procedures may progress more slowly than expected. Strong coordination between the EPC contractor, BESS supplier, and grid operator is essential to ensure safe integration, stable operation, and long-term system reliability.

    This is where integrated models outperform fragmented ones. When engineering, procurement, execution, and O&M are managed by the same team, integration risks decrease significantly. As an integrated EPC and operator, Enexus can coordinate all parties with a single point of accountability — exactly what foreign investors appreciate when entering complex markets such as Romania.
