According to Paraguayan news [1] (Spanish), the failure was on the Argentina side of the Yacyretá hydroelectric (which is shared by Argentina and Paraguay), not at the plant itself. Only a few Paraguayan towns close to the hydroelectric itself were affected, while Argentina and countries it resells electricity to were out of power.

I can confirm, at Paraguay, only two small towns (Pilar y Ayolas) where affected and for a short period of time. Source: I live at Paraguay.

Nice to see Paraguay present here on HN, I live here in Asunción.

I also heard of some people near Luque without power Sunday and Monday, but I'd guess it was an unrelated ANDE incident.
