An ordinary trailer can weigh 40 tons, and an ordinary oil column, for example - you need a set of generators.
Marine diesel generators (which can go in a container) are about 8 MW - there are 4 in the video.
Total peak power ~32 MW because one trailer was released - only half of the 16 MW.
The 16 MW is almost identical to the two Mi-26s (20 tons payload) with 11400 hp == ~ 8400 kW.
The maximum load for 2 trailers in total is ~ 40 tons -For example, 100.
