German system integrator Intilion has delivered all the components for one of Switzerland’s largest standalone BESS.

“In addition to the battery containers; transformers, inverters, controllers, cabling, and other accessories have also arrived at the project site in Kappel,” the company said on Tuesday.

Intilion received the 25 MW/65 MWh BESS order from Swiss energy company Primeo Energie in December. At that point, construction was set to begin in spring this year.

Intilion carried out component delivery and international transport from the BESS factory in China, including customs formalities and approvals. The use of a warehouse near the project site, requested by Primeo Energie, enabled construction-area delivery flexibility, in line with progress at the site.

Transport of the BESS from Rotterdam to Birsfelden was carried out by inland waterway, rather than road, eliminating cross-border approval procedures such as those for special transports.

The project components will be assembled, wired, and installed before commissioning.

Opinion & Analysis

Falling li-ion battery prices mirror solar photovoltaics trends: Is there a role for second-life batteries before recycling? Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.
