After the finale of Dark, does Winden still have a nuclear power plant?

It seems that without Unknown to force the mayor to sign the document, the nuclear plant was never built in the origin timeline. There's an intersection with three traffic lights that we periodically see in the series, and long shots always show the two cooling towers in the background, one of them directly above the left light, as in the screenshot from this site:

And here's a screenshot showing the intersection in 1987, from episode 5 of season 2:

In the final shot of Jonas and Martha as they disappear, we see the same sort of long shot of the intersection with the three traffic lights (the bus stop seems to be positioned differently in the origin world, directly facing down the length of one of the roads leading away from the intersection rather than being positioned on the side of that road and facing its opposite side as in the 1987 shot, but the position of the traffic lights and the street light on the pole is the same in all these shots). But here, you can see that directly over the left traffic light there's just a patch of moonlit sky with no silhouette of a cooling tower (click to see a larger version of this image, and you may need to turn up your screen brightness):

I think it's implied that this is why Regina doesn't get cancer in the origin timeline, while she does in the two timelines of the knot--either she developed it from living around a nuclear plant her whole life, or her mother was already doing work at the plant before she was conceived and it affected her ova.

In the final dinner scene in the origin timeline we also see a family picture of Regina, Claudia, and Bernd, he looks like he's dressing more casually than in the other timelines where he ran the nuclear plant and was always seen wearing a jacket and tie:
