TN HB2054

Creates the "Data Center, Artificial Intelligence, and Clean Transition Tariff Accountability Act" establishing voluntary clean transition tariffs for large energy-intensive users with peak electric demand of 25 MW or greater, including data centers, AI facilities, and crypto operations.

Requires large energy-intensive users to fund 100% of incremental clean power generation and bear proportional costs of transmission, distribution, and substation upgrades needed to serve their load.

Prohibits recovery of any infrastructure or generation costs from residential or small business customers (defined as 50 or fewer employees), requiring local power companies to demonstrate no rate impact before approving service.

Directs the Tennessee Public Utility Commission to coordinate with TVA and local power companies on tariff compliance, with annual reporting to the legislature beginning January 1, 2027.

Takes effect July 1, 2026, applying to all new or expanded large energy-intensive users seeking electric service on or after that date.
