MO HB1289

Prohibits utilities from collecting, storing, selling, or transferring smart meter data to third parties, except for internal use for billing and compliance with utility regulations.

Requires utilities to destroy smart meter records containing identifying information about individual residences within one year; aggregate data without identifying information may be retained indefinitely.

Establishes civil penalties of $10,000-$25,000 for first violations and $100,000-$200,000 for second violations of data transfer or retention requirements, with potential for attorney fees and injunctive relief.

Makes smart meter information obtained in violation of the law inadmissible as evidence in Missouri courts, and renders any evidence discovered as a result of such information also inadmissible.

Allows smart meter evidence only when obtained through a proper Fourth Amendment warrant based on reasonable suspicion of criminal wrongdoing, issued before the one-year data retention deadline.
