I was under the impression that Belt and Road initiative was rails, trucks and ports / shipping / docking. Not so much power plants or EVs.

They do energy sector stuff as well. They've invested in several big hydropower projects over the years and a number of fossil fuel plants. I believe in the past year or two there's been an effort to refocus the projects towards clean energy as well, calling it the "Green Silk Road."

Of course, it appears somewhat controversial how successful these projects have been.
