• Can Utilities Cash In on AI Without Making Consumers Pay?
  OilPrice · Sep 14, 2026

  As utilities increasingly explore the integration of artificial intelligence (AI) into their operations, the question arises whether these advancements can be leveraged for profit without passing costs onto consumers. AI technology has the potential to enhance efficiency, optimize energy distribution, and improve predictive maintenance, which could lead to significant cost savings for utility companies.
