US States Implement New Power Tariffs for Data Centers

A wave of state-level regulatory actions is shifting the financial burden of electrical grid upgrades from residential ratepayers to high-demand industrial users. In May 2026, the Oklahoma House and Senate unanimously passed the Data Center Consumer Ratepayer Protection Act, requiring facilities adding 75 megawatts or more—including AI and cryptocurrency operations—to fund their own power plants and substations. The bill now awaits signature from Governor Kevin Stitt.

Similarly, the Public Service Commission of Wisconsin approved a payment structure requiring data center operators, including Microsoft and Vantage, to cover the full cost of generators and transmission infrastructure. This decision follows a push by We Energies to prevent ordinary industrial customers from subsidizing massive energy loads. In Oregon, the Public Utility Commission ordered Portland General Electric to implement a new tariff regime effective June 10, which includes a 1-cent-per-kilowatt-hour surcharge on mega-data centers to fund energy-efficiency projects.

In Louisiana, the Public Service Commission is currently developing large-load tariffs under the Lightning Initiative to accelerate economic development without penalizing existing customers. Commissioner Davante Lewis emphasized the need for these guidelines to ensure the state remains competitive. Meanwhile, legal counsel in Louisiana noted that the Federal Energy Regulatory Commission is expected to act on interconnection proceedings for significant new electrical loads by June 2026.
