TVA board approves higher power rates for data centers
The Tennessee Valley Authority (TVA) board approved a new, higher electricity rate class for data centers, effective October 1. This change, phased in over three years, is expected to increase billing by about 10% and includes new capacity commitment charges for large facilities. The move aims to ensure the growing costs of serving data centers are not passed on to residential customers, with the impact expected in areas like North Alabama where companies like Google, Meta, and DC BLOX operate.
The Tennessee Valley Authority (TVA) board has officially approved a new, separate electricity rate class for data centers, set to take effect on October 1. The decision, made last Thursday in Memphis, aims to address the escalating power demand from the data center industry across the TVA region and ensure that associated costs are not borne by residential and other customers. This new rate structure, which will be phased in over three fiscal years, is projected to result in an average billing increase of approximately 10% for data centers.
The new policy reclassifies data centers out of the manufacturing category, placing them into four new categories based on their contract demand. Furthermore, new or expanding data centers with loads exceeding 5 megawatts will incur a capacity commitment charge of about $1.5 million per megawatt, payable over three to five years. TVA Chief Financial Officer Tom Rice stated that the measure reflects the costs of serving large data center loads.
The change is expected to significantly impact areas like North Alabama, where TVA supplies power to local utilities such as Huntsville Utilities. Major tech companies including Google, Meta, and DC BLOX operate data center campuses in the region, specifically in Bridgeport (Google) and Huntsville (Meta, DC BLOX). Google had previously announced a $1.5 billion investment in its Jackson County campus through 2027, committing to cover its power and infrastructure costs.
TVA Board Chair Mitch Graves emphasized that the new rates are intended to protect "hardworking American families and small businesses" from the rising electricity consumption of AI and advanced industries. The board also approved the utility's long-range power plan and a fiscal 2027 budget, which includes over $13 billion for generation and transmission work through fiscal 2029. U.S. Senator Tommy Tuberville also commented on the importance of power contracts for data centers in Alabama, noting the state's growing number of facilities.
