Sighting near turkey point nuclear power plant Miami, Fl.

In miami Florida about 20 years ago.
I was outside, I looked up in the sky due south and saw a light illuminating the sky.
The light was soo bright it lit up the early evening sky. It moved in a odd and swift way. Many years later I realized that due south from where I was about 5 miles west from the coast is 'turkey point' which is a nuclear power plant. I wonder to this day if the power plant had anything to do with the sighting. I was with my mother and cousin and it lasted for a good 20 minutes.
