MLGW rate increase (xAI context) Memphis Light Gas and Water
Memphis Light, Gas and Water implemented the final 4 percent step of a 12 percent multi year rate increase approved by the Memphis City Council back in 2023, adding about 5 dollars a month to a typical residential bill starting in January 2026.

TVA data center rate class proposal Tennessee Valley Authority
TVA is a federal agency, not a state regulated utility, so its own board sets rates rather than a public service commission. The TVA Board of Directors voted at its August 20, 2026 quarterly meeting to approve a dedicated data center rate class, moving data centers off the standard industrial rate; the new rate takes effect October 1, 2026, phased in over three fiscal years to about a 10 percent average bill increase for data center customers, plus new upfront capacity commitment charges of roughly 1.5 million dollars per megawatt for new interconnections.
