TVA proposes new data center power rate starting in October, with 10% average increase
The Tennessee Valley Authority (TVA) has proposed a new electricity rate for data centers, set to take effect October 1, 2026, which includes an average 10% increase. This measure aims to accommodate the growing power demand from AI and hyperscale data centers without passing costs onto other existing customers. The proposal includes a "Ratepayer Protection Pledge" requiring data center companies to cover infrastructure costs and potentially procure their own power supplies.
The Tennessee Valley Authority (TVA) has proposed a new standard electricity rate for data centers, which is slated to take effect on October 1, 2026. The utility anticipates this new rate will result in an average all-in billing impact of approximately 10%, which will be phased in over three consecutive fiscal years.
The TVA states that the primary goal of this proposal is to manage the rapidly increasing power demand from artificial intelligence and other large computing facilities across its service territory. The new rate structure is designed to prevent the cost of serving these large data centers from being shifted to existing residential, commercial, and industrial electricity customers, aligning with what the TVA terms its "Ratepayer Protection Pledge." Under this pledge, hyperscale data center and AI companies would be responsible for developing or procuring new power supplies, funding necessary transmission and distribution upgrades, and paying for dedicated power and infrastructure.
Key provisions include capacity commitment provisions for data center B, C, and D rate schedules, introducing a Capacity Commitment Charge (CCC) for new or expanding loads above 5 megawatts to recover incremental capacity costs. Additionally, a "Power Interruption Provision" is planned to address reliability concerns for data centers starting operations before their dedicated power capacity is fully available. The TVA has indicated its openness to working with data center customers who wish to implement their own generation or alternative power solutions, provided these arrangements align with the principles of the Ratepayer Protection Pledge.
