SB 1600 requires data centers in Tennessee with over 20 megawatts of power capacity to register with the Tennessee Public Utility Commission (TPUC) starting January 1, 2027. Electric and water utilities serving these registered data centers must report monthly usage and service rates to the TPUC, which will compile and publish this data on its website. The law imposes penalties of up to $1,000 per day (capped at $25,000) for late registration or failure to update registration details. This bill directly affects large data center operators and their utility providers, creating a public reporting system to track energy use and costs for these facilities.
