Actually what's most important to know is if they would actually keep thermite on hand, in some sort of safe storage, for potential repairs, or rely on a thermite-welding service or department that wasn't local for this. Thermite is stable, but sensitive to the right atmospheric or external ignition agents. They wouldn't keep it stacked in big sacks.

Because if they didn't store thermite in the basement/sub-station (which would actually explain molten, lava-like flows of slag and other metal by-products), then thermite is still not really logical as a presence in the dust that issued from the collapses - unless the stored thermite found a pocket of air or another escape through the tons of material crashing down on it.
