An enhanced electrical power generating system. In a described embodiment, an electrical power generating system for use in a subterranean well includes a flow passage formed through a tubular string in the well, a flow region in communication with, and laterally offset relative to, the flow passage, an electrical power generator operative in response to flow of fluid through the flow region and multiple flow restrictors in the flow passage. The flow restrictors are operative to influence at least a portion of the fluid to flow from the flow passage through the flow region.
