The aim of the project was to implement a 250 MW battery storage system (‘grid booster’) that compensates for short-term fluctuations in the transmission grid and reduces bottlenecks. It thus makes a decisive contribution to stabilising the German electricity grid and ensuring security of supply.

The main challenges lay in the large number of partners involved – from the general contractor and engineering firms to internal specialist departments – as well as the tight deadlines and the complexity of the innovative technology. Risks had to be identified early on and mitigated preventively in order to avoid delays.

Rensys took over central project management and established clear structures for planning, documentation and communication:

• Structured analysis of the contract documents, of the PM manual and the schedule with the general contractor
• Introduction of an audit-proof documentation system on SharePoint to ensure transparency and traceability
• Definition of work packages and milestones in MS Project, supplemented by continuous reporting to project management
• Weekly project meetings, carefully prepared, conducted and followed up to involve all stakeholders
• Efficient interface coordination between specialist departments, manufacturers and project management to ensure a smooth flow of information

The project was completed within the specified time frame and budget. Critical risks were mitigated at an early stage, and potential bottlenecks were resolved in close consultation with all parties involved. The grid booster was successfully commissioned and has since made a significant contribution to stabilising the German transmission grid.

With clear project management, reliable communication and well-thought-out process design, Rensys ensured the successful implementation of the network booster in Kupferzell. The project is a prime example of the combination of innovative strength and structured management – and sustainably strengthens the security of supply in the energy system.
