Battery Maker Fluence shares jumped another 18% in premarket trading on Wednesday, following a 41% surge over the previous two sessions.

Fluence Energy expects US orders to make up a large share of its backlog next year as power demand surges from electrification and data center growth.

The company sees roughly half of global demand coming from the US, Chief Executive Officer Julian Nebreda said in an interview Monday.

US orders slowed earlier in the year amid uncertainty around tariffs but President Donald Trump’s big tax bill, which preserved incentives for battery storage, has helped restore some confidence in the market, Nebreda said. Fluence is on track to meet eligibility requirements for those incentives, he added.

“There has been a more recognition that the way to win in the US is offering a domestically produced market, and we’ve been working on it,” Nebreda said.
