The Electric Power Board of the Metropolitan Government of Nashville and Davidson County is a mouthful. Its operating name, Nashville Electric Service (NES), sounds much better. And talking of sound, the legendary "Nashville Sound" would be hard to hear without the resources of this power distributor, which serves more than 360,000 customers in central Tennessee. NES is one of the largest government-owned utilities in the US. The company is required to purchase all its power from another government-owned operator, the Tennessee Valley Authority (TVA).
