Missing from the article:
- Battery capacity: 1MWh [1]
- Charging power: 6MW (assuming they charge the full battery in the 10 minutes mentioned in the article)
Unfortunately, I cannot find the article, but I believe I once read that charging the batteries that quickly caused problems with power grid stability, so they had "auxiliary batteries" at the ports that they charged with lower power, and then transferred the energy from those batteries to the ship batteries with high power, which effectively tripled the battery cost. [EDIT: the issue is actually mentioned in article [1], where they have two 410kWh shore charging stations]
