The Tennessee Valley Authority has introduced a significant change in its electricity rate structure, specifically for data centers, affecting its seven-state territory, including parts of western North Carolina.
During the utility’s recent board meeting in Memphis, Tennessee, the new rate was approved alongside the progression of its Integrated Resource Plan. This plan, which dictates the utility’s energy strategy until 2050, has sparked debate among environmental advocates across the region.
The Integrated Resource Plan notably reduces TVA’s investment in renewable energy sources such as solar and wind power, opting instead for coal, gas, and nuclear energy. This decision has been met with criticism from environmental groups concerned about the reliance on fossil fuels.
The revised rate, set to be implemented on October 1, 2026, will introduce an approximate 10% increase, which will be phased in over a period of three years.
TVA spokesperson Scott Brooks highlighted the utility’s commitment to staving off further rate hikes for its electricity consumers. “One of TVA’s missions is economic development,” Brooks stated. “We try to balance that line where we welcome economic development, but, but not at the cost or the expense of people who pay their power bills.”
Under the new structure, large customers will encounter an upfront cost. TVA anticipates a surge in its electric load, projecting it to rise between 9 and 33 gigawatts by 2040.
According to WPLN’s report, data centers accounted for 10% of TVA’s electric load last year. Board members foresee continued growth and justify the strategic shift as necessary to accommodate this demand.
Despite delaying coal plant closures and a new gas plant investment in Cheatham County, board members argue these steps are crucial for consistent growth. However, critics warn this prolongs reliance on fossil fuels, the primary drivers of climate change, and could impose financial burdens due to high maintenance costs, such as the projected $730 million for the Cumberland Fossil Plant.
Stephen Smith, executive director of the Southern Alliance for Clean Energy, expressed concern: “You’re about to be run over by a truck, and instead of taking a big step to get out of the way, TVA took a tiny step that basically still leaves you in the path.”
The Southern Alliance for Clean Energy published an op-ed suggesting the changes could result in costs being transferred to consumers. Maggie Shober, a research analyst for the organization, raised several questions during the board meeting. Clarification is needed on whether the rate applies to all large customers or specifically data centers, how stranded assets would be managed if a data center ceases operations, and how these centers’ costs will be calculated.
Stephen Smith warned, “Making them only pay 10% more is no guarantee that those costs are not going to be spread onto the customers.”
