In Portugal a three phase connection is rare due to costs. The electrical bill is structure so that you pay for the peak power consumption (kVA's) and how it's structured to favor 1 phase connections. 1 phase kVA options: 1,15; 2,30; 3,45; 4,60; 5,75; 6,90; .... 3 phase kVA options: 6,90; 10,35; .... The kVAs levels increase by 5 Amps on each phase so you get much more levels on 1 phase connections.
