NES aligns with TVA on higher electricity rates for data centers
Nashville Electric Service (NES) has officially adopted new, higher electricity rates for data centers, aligning with a recent decision by the Tennessee Valley Authority (TVA). This change, effective October 1st and phased in over two years, will increase power costs for data centers by approximately 10%. The move follows community backlash against data center development in Nashville and is intended to protect existing ratepayers.
Nashville Electric Service (NES) has officially adopted a new electricity rate class for data centers, aligning with the Tennessee Valley Authority’s (TVA) decision earlier this summer. The TVA's governing board unanimously approved separating data centers from its manufacturing service rate class, resulting in a roughly 10% increase in electricity costs for data centers. TVA leaders indicated this change supports a federal pledge to protect ratepayers amidst a national surge in data center development.
NES revenue and rates manager Barry Daniel confirmed that the rate change will take effect on October 1st, mirroring the TVA's implementation date. However, the increased rate will be phased in, with a 5% annual increase over the next two years. Daniel clarified that NES's actions are intended to ensure its billing structure remains aligned with how TVA bills NES.
This decision by the NES Electric Power Board follows earlier discussions on developing a separate retail electricity rate and requiring data centers to pay more upfront for construction costs. It also comes after a summer marked by significant community backlash against data center development within Nashville.
