Client Challenges.
SMA Intercon required a contractor capable of delivering a battery energy storage system in rural Germany to support their commercial energy storage investment model. The project involved storing electricity purchased during off-peak periods and selling it back to the grid during higher-rate periods.
The project presented unique challenges with a split-site configuration requiring coordination across two separate locations approximately 600-700 metres apart – the 110kV AIS substation and the battery storage facility. This rural location demanded comprehensive permitting coordination with German authorities, extended temporary power solutions, and dual site welfare facilities. The client needed a design and build contractor with EPC capabilities who could navigate rural German regulatory requirements whilst delivering reliable infrastructure across the separated sites.
