Is it realistic for me to self-study power engineering?
Background: I have a degree in physics from UC Davis, took some of the upper division EE courses there and have been working as a electronics/rf tech since in the Sacramento area. I've been frustrated by my lack of employability in more advanced roles (need experience to get experience!), or the need for a degree specifically in an engineering field, or a professional license, and am contemplating going back to school at Sac state for power engineering but it would be a long term plan because of conflict with my work schedule.
So I'm looking for opinions from people already in the field and with more knowledge on what companies/utilities would be open to a less traditional study route, is it even worth it in this economy to try to self-study? Are there any projects that would definitely make me be taken more seriously?
