AES and Siemens' energy storage venture, which also counts Qatar Investment Authority as an investor, priced the offering above its range.

Fluence, the Germany-based energy storage system provider launched by industrial equipment producer Siemens and electric utility AES, is floating on the Nasdaq Global Market today in an $868m initial public offering.

The company priced 31 million shares at $28.00 each, significantly higher than the $21 to $24 range it had set for the offering last week.

Founded in 2018 as a joint venture between the corporates, Fluence produces grid-scale battery storage systems which improve the efficiency of renewable energy installations.
