TVA SGPO

[Bradfield]

I've been invited for EEI testing for a TVA SGPO position. I'm currently in the petrochemical industry as an operator, and the compensation is quite good ($125K or so before OT). The SGPO compensation is approx. $80k for the first year, and I could manage on that income if my pay was to rise quite quickly after that first year. Is this a reasonable expectation?  Lastly what could I expect to top out in pay, and how long does that generally take. Sorry for the newb questions.
Thanks in advance
