Local driver Porteiro lapped the Spanish track in 1:20.989s to become the fourth different pole sitter in the four races so far this season.
Porteiro's Epsilon teammate and Championship leader Robert Kubica will start alongside him on the front row, after securing the fastest time in his session. It is the first time this season that one team has annexed the front row.
Frenchman Eric Salignon will line up third after securing the second fastest time in Porteiro's 'faster' session, just 0.226s off the Spaniard. American Colin Fleming will start fourth, after finishing 0.018s behind Kubica in the 'slower' session.
The World Series by Renault cars are split into two 15 minutes qualifying sessions to limit the problem of traffic ruining hot laps.
Because Porteiro posted a faster time than Kubica, the drivers in the Spaniard's session will start on the odd-numbered grid slots. The drivers in Kubica's slower session will start behind him on the even numbered grid slots.
