Ufo monitoring power grid and electricity.

As I was walking south down a sidewalk on Recker and Guadalupe, I heard an electric surge from power lines above me, and when I looked up there was this silent military sized large drone object hovering about 500-1000 feet above the power lines. At first it kind of floated, and a contraption extended from it, like the head of the robot from the 80s film, "Short Circuit," and it seemed to monitor the power lines. Then for about 20-30 seconds the drone remained stationary above the power lines at a hover.  The ufo was the shape and form of a playstation controller.  When I moved north to get a better look at it the ufo did a slight glide manuever and then vanished without a trace.  If it was a drone I would've seen it as it fled but this thing literally just vanished in thin air. I believe it was analysing or monitoring the power grid. I don't think the electric company has sophiscated drones like this to send out and monitor power lines, it was a uf! o!
