1. An electrically controlled subsea production system, comprising:
- a subsea electrical distributor that receives a high direct current (DC) voltage, wherein the electrical distributor converts the high DC voltage to a lower DC voltage; and
a plurality of subsea trees coupled to the subsea electrical distributor, wherein valves of the subsea trees selectively operate based on the lower DC voltage.
