At an October 7 event in Berlin, Sungrow described efforts to support European storage projects beyond supplying battery systems, including grid simulation, compliance testing and localized manufacturing. The company said its Polish battery factory is scheduled to open next year, with investment estimated at about €250 million; its expansion plans come as German tenders and proposed grid-fee rules create new project deadlines.
Sungrow set out plans to broaden its role in Europe’s utility-scale battery storage market at its Utility Connect event in Berlin on October 7, describing work on grid simulation, compliance testing and local manufacturing alongside battery supply. The strategy targets project developers facing lengthy grid-connection processes and changing network requirements, particularly in Germany and the wider DACH region.
The company said it is continuing work on a battery manufacturing facility in Poland, scheduled to open next year. Representatives told Energy Storage that the planned investment is now estimated at about €250 million. Sungrow said local production could help address European supply-chain exposure and lead-time bottlenecks, though the facility’s expected capacity and output were not specified in the report.
At the Berlin event, Sungrow presented market research, technical developments and customer insights, with an emphasis on services that can be completed before equipment reaches a project site. Those efforts include pre-connection grid simulation and compliance testing intended to help developers prepare for network-operator requirements and connection approvals.
Sungrow also described a 30 MW grid-simulation facility in China, where it tests hardware and controls under simulated grid conditions, including faults and low grid impedance. The company outlined grid-forming functions such as voltage-source operation, synthetic inertia and dynamic voltage regulation, and claimed response times of less than 10 milliseconds. The reported performance figures are company claims; the source did not provide independent test results.
Grid Readiness Could Shape Storage
The announcement reflects a shift in what utility-scale storage suppliers may need to offer as European projects encounter tighter technical requirements and lengthy connection processes. Developers must assess not only battery cost and delivery, but also how a system behaves on the grid and whether it meets local compliance rules. Pre-commissioning simulation and testing may help identify issues earlier, although the report does not quantify possible savings in approval time or project cost.
For Sungrow, the combination of hardware, power conversion experience and preparation work could support its stated goal of building a stronger position in storage. Company representatives estimated its share of Germany’s utility-scale solar PV market at about 30% to 40% and said it wanted a similar position in storage. That is a company estimate and ambition, not an independently verified storage-market share or a confirmed outcome.
Local manufacturing could also matter to buyers seeking more predictable supply, but the planned Polish facility’s contribution will depend on its eventual production scale, schedule and ability to supply European projects. Those details were not reported. The wider point for developers is that supplier services delivered before installation may carry added value when regulatory deadlines and grid connection requirements shape project economics.

German Auctions and Fee Rules
Sungrow’s focus on Germany comes as the market prepares for several developments relevant to storage projects. One is a planned 2 GW auction in May 2027 for new generation capacity that is open to batteries. According to the source report, this tender does not impose the same long-duration generation requirement as earlier auctions, which could create opportunities for shorter-duration battery projects. It is separate from Germany’s broader capacity-market plans.
Another issue is a proposal by Germany’s Federal Network Agency, known as Bundesnetzagentur or BNetzA, to change grid-fee rules. Under the proposed framework described in the report, developers seeking to retain an existing exemption would need to make a final investment decision before the new rules take effect and commission their projects by August 4, 2029.
The proposal also describes evidence requirements for demonstrating investment commitments. These include binding equipment orders covering at least 50% of investment volume, with supporting evidence due by March 31, 2027. The rules remain a proposal in the source material, not a final framework. The timing may affect procurement and project decisions, increasing the importance of clear equipment commitments and early technical preparation.

Factory Output and Rules Remain Open
Several details needed to judge the scale of the strategy were not provided. These include the Polish facility’s planned production capacity, which battery products it will make, how much output will be directed to European projects and whether its opening schedule could change. The report gives an estimated investment of about €250 million, but not a detailed construction or production timetable.
It is also unclear whether Sungrow’s grid simulation and compliance work will shorten connection approvals, reduce project costs or change approval outcomes. The company described its test facility and capabilities, but the source did not include independent performance data or confirmation from European grid operators that the tests satisfy specific connection requirements.
Germany’s grid-fee reforms are still presented as a proposal, and the final framework and effective date are not established in the source material. The May 2027 auction is described as planned; its final terms and the projects that may participate remain subject to the relevant process. Sungrow’s storage-market ambition should likewise be distinguished from a measured market position.

Deadlines Put Preparation in Focus
The next milestones identified in the report are Germany’s proposed investment-evidence deadline of March 31, 2027, the planned 2 GW battery-eligible auction in May 2027, and the proposed commissioning cutoff of August 4, 2029, for developers seeking to retain the existing grid-fee exemption. The exact timetable depends in part on how the proposed fee rules develop.
For Sungrow, the next visible test will be progress toward opening its Polish facility in 2027, along with whether it can translate the services presented in Berlin into project deployments and a larger storage presence. The source report does not identify specific customer contracts tied to the factory or give a confirmed rollout schedule for its European validation services. Developers and market participants will be watching for those details as auction conditions and grid rules become clearer.

Key Questions
What did Sungrow announce at its Berlin event?
Sungrow presented a European storage strategy that includes grid simulation, compliance testing and localized manufacturing, alongside its battery-system supply. The event took place on October 7, 2026.
Where is Sungrow’s planned European battery factory?
The company is continuing work on a battery manufacturing facility in Poland, which it says is scheduled to open in 2027. The investment is estimated at about €250 million, but the source did not report planned production capacity.
What German storage auction is planned for 2027?
The report describes a planned 2 GW auction in May 2027 for new generation capacity that is open to batteries. It says the auction does not impose the same long-duration generation requirement as earlier tenders and is separate from Germany’s broader capacity-market plans.
Are Germany’s proposed grid-fee rules final?
No. The report describes proposed rules from the Federal Network Agency. Under the proposal, projects seeking to retain an existing exemption would face investment-decision and commissioning deadlines, as well as requirements to document equipment commitments.
Has Sungrow’s claimed grid response time been independently verified?
The company cited response times of less than 10 milliseconds for its grid-forming capabilities. The source report did not provide independent test results, so the figure should be treated as a company claim.
