Was macht ihr und was unterscheidet euch von euren Wettbewerbern?	At 8Energies, we believe that the energy transition must be followed by a flexibility transition. We have joined forces to make the European power grid more flexible, convinced that grid flexibility is the decisive next step on the path toward carbon neutrality and one of the most important challenges of the coming decades. Our core activity is the development, financing, and operation of large-scale stationary battery energy storage systems. With more than 40 years of combined management experience in rapidly growing technology companies, we apply lean, execution-driven processes to an area that has historically been complex, lengthy, and only partially digitized. Our exclusive focus is on making the entire project lifecycle, from identifying suitable sites and securing grid access to construction and commissioning, as efficient and scalable as possible. 8Energies operates as a next-generation lean energy company. By hiring only top-tier talent in technical and operational excellence, we are able to develop, finance, and operate large energy infrastructure projects with a small, highly effective team, enabling faster execution than traditional market players. Our large-scale battery storage systems make renewable energy available around the clock. They ensure that clean electricity can be delivered even when the sun is not shining and the wind is not blowing, making battery storage the missing link for long-term climate neutrality and a resilient renewable energy system. 8Energies was founded to accelerate the rollout of grid-scale battery storage. Our ambition is to bring projects online as quickly and as grid-beneficially as possible, not only participating in the expansion of storage infrastructure, but actively driving and accelerating it.
Wie schätzt ihr den Markt 2026 in eurem Tätigkeitsfeld ein?	Assessment of the market in 2026 within BESS Project Development By 2026, the European and particularly the German utility-scale battery storage market will have entered a new phase. The era of large-scale greenfield BESS development in Germany is effectively over. Demand for Ready-to-Build projects has significantly outpaced supply, driving RTB prices to record levels while grid connection points are increasingly overbooked or economically restricted. At the same time, the market is facing saturation effects much earlier than anticipated. According to BDEW data, at least 78 GW of large-scale battery storage projects above 1 MW have already received formal approval in Germany. This figure clearly indicates that the pace of BESS expansion has been widely underestimated. As a result, the market is shifting from a development-driven phase to one focused on execution and operations. We expect 2026 to become a boom year for projects going live, with substantially more battery systems being connected to the grid and reaching commercial operation than in previous years. This will accelerate the transformation of many early-stage developers into IFPs (Independent Flexibility Providers) and portfolio operators, making portfolio management, dispatch optimization, and risk management of flexible assets core competencies. Grid access will remain the key structural bottleneck. While Flexible Connection Agreements (FCAs) are increasingly used to manage grid constraints, their lack of standardization introduces technical and economic uncertainty that complicates project valuation and financing. In parallel, co-located battery storage will become a defining trend. As PV expansion continues to drive price cannibalization and negative price hours, co-locating batteries at existing PV grid connection points enables more efficient grid usage and creates additional, predictable revenues for PV assets. We expect this model to move rapidly into the mainstream, a development we address in detail in our upcoming whitepaper with Enspired and Goldbeck Solar. Finally, system design is evolving. By 2026, we expect a noticeable shift toward longer-duration storage, with four-hour systems accounting for a growing share of new deployments as revenue opportunities increasingly move beyond short-term services toward intraday optimization and system stability. Overall, 2026 will mark the transition from hype-driven development to industrial-scale execution. Competitive advantage will be defined by speed of delivery, grid intelligence, and the ability to operate and optimize flexible asset portfolios at scale.
Was sind eure größten Herausforderungen?	Our biggest challenge remains grid connection, both in terms of availability and process quality. Over the past two years, grid operators have been confronted with an unprecedented surge in battery storage connection requests. This has led to longer processing times, increasing procedural complexity, and limited transparency around actual grid availability. In many cases, developers are required to demonstrate advanced project maturity very early, even though grid capacity and connection conditions remain uncertain. This creates a structural mismatch between project development timelines and grid planning processes. Flexible Connection Agreements (FCAs) have emerged as an important tool to alleviate grid constraints, but in practice they often introduce new technical and economic uncertainties. Non-standardized requirements, restrictive ramping constraints, and unclear curtailment rules can significantly limit operational flexibility and revenue potential, complicating both project valuation and financing. A key additional challenge is the limited digitalization of many grid operators, which currently prevents the effective implementation of fully dynamic FCAs. Fully dynamic constraints require real-time or near-real-time grid forecasts, situational operating limits, and reliable, timely communication between grid operators and asset operators. While this represents the target model for many grid operators, the necessary forecasting, calculation, and communication capabilities are often not yet available at scale. As a result, most FCAs today remain static or rule-based, falling short of their full system and economic potential. Addressing these challenges will require greater standardization, clearer regulatory frameworks, and accelerated digitalization of grid operations. Without this, grid connection will remain the central bottleneck for scaling battery storage at the pace required by the energy transition.
Welche Wünsche habt ihr an an Politik, Netzbetreiber und andere?	To unlock the full potential of utility-scale battery storage, we see three key areas where action is needed. First, there needs to be greater awareness of the battery storage business case, particularly in the context of Flexible Connection Agreements. Technical constraints defined in grid connection contracts have direct and sometimes decisive impacts on revenue models, financing viability, and ultimately on whether projects can be built at all. We encourage grid operators to consider the operational and economic realities of BESS when designing FCA parameters, especially with regard to ramping requirements, curtailment rules, and compensation mechanisms. Second, we call for more transparency and clearer communication throughout the grid connection process. Developers need early, reliable information on grid availability, realistic connection timelines, and the concrete requirements for securing binding grid reservations. Standardized procedures, clear milestones, and defined response times would significantly reduce uncertainty, improve project quality, and lower transaction costs for all parties involved. Third, we see an urgent need to accelerate the digitalization of grid operations. Fully dynamic connection models represent a powerful instrument to integrate more storage without immediate grid expansion, but they can only work if supported by robust forecasting, data exchange, and communication systems. Policymakers and regulators should actively support the development of technical standards and regulatory frameworks that enable grid operators to implement dynamic, transparent, and scalable connection models. Taken together, these measures would not only reduce friction in the grid connection process but also help align grid planning, market design, and storage deployment. This alignment is essential if battery storage is to play its intended role as a system-relevant infrastructure for a secure, flexible, and climate-neutral power system.
