Memphis Light Gas & Water is exploring alternatives to the Tennessee Valley Authority after a Siemens study suggested potential savings of up to $1.9 billion over two decades by generating its own power and joining MISO. While bond rating agencies warn that leaving TVA could negatively impact Memphis' credit rating and borrowing costs, proponents argue that cheaper wholesale power from alternative suppliers could help lower electricity bills for residents.
