(Reuters) -Renewable energy storage firm Fluence Energy Inc said on Tuesday it is aiming to fetch a nearly $4 billion valuation in its U.S. initial public offering, as investor interest in such technologies soars alongside growing calls to limit climate change. The company, a joint venture between Germany’s Siemens AG and U.S.-based AES Corp, says it is looking to offer 31 million shares priced between $21 and $24 apiece. At the top end of that range, the IPO would fetch $744 million in proceeds. Arlington, Virginia-based Fluence serves major utilities, developers, as well as commercial and industrial businesses, promising increased efficiency through its digital platform designed for renewables. Global investors and lawmakers have begun pushing for more sustainable and environmentally friendly ways of doing business amid heightened climate change concerns. Tapping into this demand, other green energy-focused companies such as Bill Gates-backed Heliogen Inc and Goldman Sachs-backed ReNew Power agreed to go public earlier this year through blank-check mergers. The company said it expects total revenue of up to $699 million for the fiscal year ended Sept. 30, a nearly 25% jump from a year earlier. Subsidiaries of AES and Siemens will continue to hold more than 91% of the voting power in Fluence after the offering, the company disclosed in its filing. The company estimates that as of May, it has eliminated 145,000 metric tons of carbon per year, roughly the same as taking over 30,000 cars off the road annually. J.P. Morgan, Morgan Stanley, Barclays and BofA Securities are the lead bookrunners for the IPO. Reporting by Niket Nishant in Bengaluru; Editing by Ramakrishnan M.
