Yeah one of the things about an engineering degree is that the base knowledge of an engineering degree often means you’re eligible as a low choice for any engineering field. I know mechanicals working in aerospace for example (and personally I regret going industrial instead of mechanical but it’s just not worth getting a second bs in engineering for that reason).

And yeah, the location thing is hard. I’ve seen some people stack courses like crazy to get in and out fast, but it’s generally understood that that’s unwise with engineering courses. If you don’t mind doing a few semesters in person you could reduce that time by finding a college thats credits transfer there with good online courses and doing all the non-engineering classes. At my university it was extremely common for engis to take math at the local community college because our university math department was notoriously bad for anyone that wasn’t a math major.

And yeah large power systems are cool as hell.
