New report warns of rising electricity costs in TN as demand for data centers grow
A ThinkTennessee report reveals a sevenfold increase in data center electricity consumption in Tennessee between 2020 and 2025, leading to rising residential electricity costs and grid reliability concerns. Amidst active resident protests, the Nashville Metro Council approved bills for stricter data center regulations and a temporary moratorium on new data center proposals, both pending final approval.
A new report from the nonpartisan think tank ThinkTennessee reveals that data center electricity consumption in the Tennessee Valley region surged sevenfold between 2020 and 2025, reaching 8.3 million MWh, enough to power over 661,000 homes. This rapid influx is altering the state's energy landscape, which previously saw flat or declining electricity use. The report indicates that Tennessee now holds 16.7% of active data center construction capacity among emerging markets, with demand five times TVA's current data center load, raising concerns about grid reliability and increased residential electricity costs.
The analysis projects a 5.1% rise in residential electricity prices by 2027 in the East South Central region, noting that residential bills in Tennessee counties with data centers climbed 3.2% from 2023 to 2024, while commercial costs decreased. ThinkTennessee President Erin Hafkenschiel emphasized that planning, pricing, and infrastructure decisions are critical to determine who bears the costs of this growth, warning of potential risks to household energy costs. The report also highlights Tennessee's low ranking in national grid reliability metrics.
The report's release coincides with significant local opposition to data center developments in Nashville. During a recent Metro Council meeting, hundreds of residents spoke against proposed data centers, including one near the Nashville Zoo and another on Fisk University's campus. Metro Council President Angie Henderson noted that 245 people registered to speak on Bill 1391, which aims to implement stricter rules for data centers.
The Metro Council approved Bill 1391, which amends city codes to impose tougher regulations on data centers, and Bill 1448, proposing a temporary moratorium on all new data center proposals within the city and county. Both bills have moved to a third and final reading for full council approval, reflecting the ongoing pushback from the community and the government's response to the rapid growth of the data center industry in the region.
