Data center growth raises questions over East Tennessee power demand, who pays for expansion
Data center growth in East Tennessee is raising concerns about increased power demand and who will bear the costs of necessary grid expansions. An advocacy group is calling for an 18-month moratorium on new large data centers in Tennessee and four other Southeastern states, citing a need for greater transparency and accountability from utilities regarding infrastructure investments. The Tennessee Valley Authority (TVA) is set to discuss changes to its long-term energy plan concerning large electric loads.
The rapid proliferation of data centers across the Tennessee Valley is intensifying scrutiny on the region's power grid, particularly concerning electricity demand and the financial responsibility for infrastructure upgrades. According to WATE 6 On Your Side, the Tennessee Valley Authority (TVA) reports an accelerating demand driven in part by data centers and artificial intelligence, marking it as the largest electric load growth seen by TVA and other Southeast utilities.
The Southern Alliance for Clean Energy advocates for an 18-month moratorium on new large data centers across Tennessee and four other Southeastern states. The organization seeks greater transparency in agreements between utilities and major power users, along with improved protections if projected demand fails to materialize. In Knoxville, the Knoxville Utilities Board (KUB) notes it currently serves three data centers, with its largest contracted to consume up to 73 megawatts, enough to power over 60,000 homes. KUB asserts that these data centers have covered upfront costs for all necessary electric system upgrades, preventing residents and small businesses from subsidizing their growth. Additionally, KUB's larger data center clients have interruptible contracts, requiring them to reduce power usage during grid strain.
Concerns persist regarding TVA's accountability for ensuring large load users fund their infrastructure. The TVA Board is scheduled to convene in Knoxville this week to consider modifications to its long-term energy plan, specifically addressing how it manages electric loads exceeding 100 megawatts. TVA acknowledges making significant investments in generation and grid infrastructure to meet growing demand.
