Hardin v. Kentucky Utilities Co.

Background

A federal agency, the Tennessee Valley Authority (TVA), and a private company, Kentucky Utilities, fought over whether two small villages—Tazewell and New Tazewell in Claiborne County, Tennessee—and a narrow corridor were inside TVA’s service area on July 1, 1957. TVA served about 62% of the county’s power users in June 1957, but supplied only a small share in the villages while Kentucky Utilities supplied most village customers. Local officials created a municipal system to take advantage of TVA’s much lower rates, and Kentucky Utilities sued to stop TVA from serving the new customers under the 1959 amendments to the TVA Act.

Reasoning

The central question was whether those villages and the corridor were part of the “area” for which TVA was the primary power source on the key 1957 date. The Court said the TVA Board’s factual finding that the county (including the villages) was a single service area was entitled to deference and should stand unless it lacked reasonable support tied to the statute’s purpose of limiting territorial expansion. Applying that standard, the Court reversed the Court of Appeals and affirmed the District Court: TVA’s Board decision had adequate factual support, so TVA could supply its low-cost power throughout the county, including the two villages.

Real world impact

The decision lets TVA provide its cheaper electricity to municipal customers in the disputed county area, reducing local electric rates and shifting customers away from Kentucky Utilities. It also makes it harder for private utilities to block TVA expansion when the TVA Board reasonably concludes an area is within its service region.

Dissents or concurrances

Justice Harlan dissented, arguing courts should review the TVA Board’s decision more strictly. He emphasized evidence that Kentucky Utilities served nearly all village customers in 1957 and said Congress intended tighter limits on TVA expansion.
