Nio Inc (NYSE: NIO) has received approval for its battery swap stations in Sweden to participate in local grid frequency regulation, helping balance electricity demand during peak periods.
Sweden's national grid operator Svenska kraftnät has formally approved Nio's battery swap stations to join Sweden's frequency regulation system (FCR-D), the Chinese electric vehicle (EV) maker announced in a statement today.
This represents a significant step in integrating Nio's energy solutions into the broader power ecosystem, the statement noted.
"Our stations will not only continue to enable fast and seamless battery swaps -- they can now also support grid stability, store excess renewable energy, and help balance demand during peak hours," Nio said.
The company currently operates 60 battery swap stations in Europe, including 8 in Sweden. In China, it has 3,563 such facilities.
"Svenska kraftnät’s approval of our Power Swap Stations as part of the frequency regulation system is a breakthrough – not only for Nio but for the entire sector," said Kajsa Ivansson Sognefur , Head of Power, Europe at Nio.
Nio began exploring grid regulation participation for its battery swap stations in China several years ago, particularly during peak summer electricity consumption periods.
In overseas markets, Nio's sole battery swap station in Denmark began providing frequency regulation services to the grid as an energy storage facility in February 2024. However, a local user told CnEVPost that the site has been shut down.
Each station participating in this service generates annual revenue in the tens of thousands of euros, according to Shen Fei, then head of Nio's energy business. Shen now serves as president of Nio's sub-brand Onvo.
Update: Changed the text regarding Denmark, as the only battery swap station there has closed.
