Absolutely!!! Have used Omron networked PLCs in fully automatic base load diesel generator power stations several times. Christmas Island, RAAF Base Scherger, Weipa etc.

Electric utilities

Yes, my last job was using Allen-Bradley 5/20e, 5/40e PLCs and 1400e PanelViews. Ethernet communications over a three ring fiber optic network.
S.C.A.D.A. of three main substations and switchyards, 138kv with 50 branch substations all monitored and controlled from a switchboard control center. The system also contained 250vdc generation and distribution as well as 6600vac 25HZ generation and distribution.

Note: Allen-Bradley120vac Triac input cards will work on 25-cycle power.
