I love cooking poached eggs at home.

Assumption: This is all sea level (+/-15 metres).

I went to a hotel with glass walls to the kitchen and watched the way they prepared the morning cooked egg orders.

On one stove top, they had an enormous pot (felt like it would cover all four of my stove-tops at home), gently simmering away at some (unknown) temperature. (The water had almost zero egg-white scum floating in it).

The chefs would drop eggs from cups into it, set timers, and then pull the eggs out after the timer had gone off.

This seemed to be an amazingly polished perfection of the process of cooking poached eggs. There could easily have been 10 eggs in at once, with room for fifteen.

My question is: What is the temperature of the massive pots of water at hotels for cooking 10 poached eggs at once?

    If it's simmering (meaning you can see small bubbles), that tells you pretty much what temperature it is... so, are you using "simmering" in technical cooking terms where you can see small bubbles or if you just mean that it was over heat but there was otherwise no water movement.

    It would be the same temperature for cooking one egg.

    It was small bubbles rising from the bottom.

In scale operations, a large 'rondo' is usually used, and as the comments above indicate it is at 'simmer' which is essentially 212 F / 100 C. A small amount of vinegar is added to the water, which helps the loose parts of the egg white coagulate and gives a nicer shape to the poached egg.

Since the kitchen you describe has glass walls, they are taking extra care for the showmanship part of the operation, having eggs in individual cups to drop in the poaching vessel.

A large vessel is used to reduce the temperature rebound of adding the cold (maybe close to room temp) eggs. As each is added, it does not significantly reduce the temperature of the rest of the water in the large pot.

The fact that the water was clear means the station cooks are under directions to continually add vinegar and skim the water. After each egg, some bits come off that have to be cleared out. If the kitchen did not have glass walls, the water would not be that clear during a busy brunch !
