SAN FRANCISCO, June 20 Reuters Electric vehicle maker Rivian said on Tuesday it has agreed to adopt Tesla39;s charging standard, giving Rivian customers access to the biggest U.S. charging network and adding momentum to Tesla39;s bid to set the industry standard.

Customers of Rivian, which has its own small network of fast chargers, will be able to access 12,000 Tesla Superchargers with adapters in the United States and Canada as early as spring 2024, the company said. Rivian also said it will make a Teslastyle charging port standard on its vehicles starting in 2025.

Tesla has struck comparable deals in recent weeks with General Motors and Ford. While other automakers get access to Tesla39;s charging network, Tesla stands to profit from selling power to a bigger group of electric vehicle drivers.

Shares of Irvine, Californiabased Rivian rose as much as 6.6 on Tuesday before paring some gains to trade up 4. Tesla shares, which are up more than 40 since late May when the leading U.S. electric carmaker announced its deal with Ford, were also up 4.

Rivian39;s plan was first reported by Reuters.
