So, I got curious…
Now I know most of these companies are not nearly as big as Centerpoint (Southern Company is probably the closest comparison, but they also generate power, in addition to distributing it). But I still thought the info is interesting.
CEO Alabama Power - BS chemistry and biological sciences; started as a lab tech with the company 35 years ago
CEO Mississippi Power - started with the company in 1984 as a co-op student, BS electrical eng (EE)
CEO Georgia Power - 33 years with Southern Company (the parent to GA, AL, and MS power), BS in engineering science and mechanics, MS in biomedical engineering
CEO Southern Company - been with the company since 1988, can't find what his BS is in, but I'll give him a pass since all the subs have technically strong leadership
CEO Entergy - 25 years with Entergy, BS mechanical eng
CEO TVA - BS mechanical eng
Southern Company and its subs also hire "locals". The CEO of MS Power is from MS, CEO of AL Power is from AL.
Florida is a little weird - they don't seem to have any technical people at the highest exec level. They do have some engineers as VPs (not listed here)
CEO NextEra Energy/Chairman Florida Power and Light - JD, BS economics
CEO Florida P&L - BS accounting
CEO NextEra Energy Resources - BS Public Policy
NextEra Energy Chief Risk officer - BS accounting (this one is a head scratcher)
