Is it conceivable that this was custom designed for the game? I've done a lot of research into the digital fonts of this genre and never seen this one before.

Thanks for your informed reply, Stephen. There's a chance this is custom, although from what I've seen, there isn't much precedent for using custom fonts in eurogames. I don't think they typically sell well enough to justify the cost of commissioning a custom design; in fact, I often see them using free or very cheap fonts.

I'm still holding out hope that there is an exact match that is commercially available somewhere. If it turns out that there isn't, I would very much appreciate a pointer to the closest alternative.

After I started this thread, I decided to look up and write the person who did the art for the game, Maura Kalusky. This morning, I got a reply!

It turns out that the typeface is called Russka, and it was designed by none other than his girlfriend. (Maura Kalusky is male.) It's actually one of two fonts of hers that are used in the Power Grid design; the other one is called Waldmeister, and it's used for some of the text elements on the game box.

According to Mr. Kalusky, Russka "should have some kind of silkscreen aesthetics", while Waldmeister "looks like printing with rubber stamps". Both fonts are available for purchase through him for €50 each.

Thanks, Spire! His contact info?

I contacted him via the private messaging system ("GeekMail") on BoardGameGeek.

His BGG username is maura.
