The main large transfers of people happened in the "Temple Bus" situation and the way it goes it seems most of those transfers of people was powered by the energy of the abducted more than anything else.
Really the Negaverse seems to be reluctant to allow more than 3 out into the world at a time without the movements being powered by stolen energy to preserve their stores being used to revive the demon queen.
Hmm, that wasn't the impression I got from the episode, myself... May need to watch it again.
In any case, the end result is pretty much the same. Even if opening such a temporary portal did drain Mettalia's energy store, there's still nothing I can think of that indicates that it requires energy to maintain the youma's existence in the world. So it'd still be a one-time cost to create the bridge... but once they did that, they could send pretty much any number of youma through it. The usual low numbers I attribute more to their desire to keep a low profile than anything else.
Not to mention that they've still got the main portal in the cafe, which from its episode seems to be a stable connection, since once the Senshi found it, they could use it themselves; it was operational on a consistent basis.
