Transmission System Overview
Big Rivers constructs, owns, operates and maintains an electric transmission system in the northern portion of western Kentucky. High-voltage electric power is delivered to our Member-Owners’ systems through this robust transmission system that contains 1,303 miles of line, 22 transmission substations and 24 high-voltage interconnections with seven surrounding electric utilities.
Big Rivers works in conjunction with our Member-Owners to evaluate transmission expansion or improvement projects driven by reliability performance. We efficiently maintain our transmission system with a focus on reliability and electricity import/export capability, and we monitor the capabilities and expansions of surrounding transmission systems. Big Rivers complies with all NERC Reliability Standards and SERC regional standards and guidelines consistent with a corporate culture of compliance.
