Nio said on Tuesday that its battery swap stations in Sweden have been approved to participate in the country’s electricity grid frequency regulation system, a move that allows the Chinese electric vehicle maker to contribute to balancing electricity supply and demand during peak periods.
Sweden’s national grid operator, Svenska kraftnät, formally authorized Nio’s battery swap network to join its frequency containment reserve for disturbances (FCR-D), the company said in a statement.

“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.
Nio operates 60 battery swap stations across Europe, including eight in Sweden. In China, the company runs 3,563 stations, forming one of the world’s largest battery-swapping networks.
Kajsa Ivansson Sognefur, Head of Power for Europe at Nio, called Svenska kraftnät’s approval “a breakthrough — not only for Nio but for the entire sector.”

The company has previously explored grid integration in China during peak summer demand and began frequency regulation services in Denmark in early 2024, though that site has since been shut down, according to local reports.
Nio’s energy business has estimated that each station participating in grid regulation could generate annual revenue in the tens of thousands of euros.
