Electrive reports that the stationary storage system is made of 4.400 batteries, coming from around 133 Taycans, according to the publication. The Taycan was made available first in 2019, so there wasn't enough time for these cells to degrade. Porsche explains that this is because the used cells don't come from commercially-sold vehicles, but rather from prototypes and testing units, who aren't employed for road purposes after the initial testing is being done.

While individual cells can be replaced, if necessary, they should last up to ten years, company officials stated. At the same time, part of the energy required for filling these batteries comes from the solar panels installed at the facility, amounting to around 9.4 megawatts of power.

Jonathan Dietrich, the project manager with overall responsibility for the battery storage system, said that "we wanted to create electricity storage capacities for the Leipzig plant in order to make the site even more economical and to increase its degree of self-sufficiency. So, it was only logical to use batteries from Taycan pre-series vehicles instead of recycling them."
