State filed suit against Entergy, an electricity provider regulated by the state PSC, alleging that Entergy violated its duty to Mississippi customers under the PSC’s rules by charging higher prices for electricity in Mississippi than in other states, with no justification in costs. The case alleged violations of the state’s consumer protection act, fraud and unjust enrichment, as well as one antitrust claim, alleging restraint of trade on the production of electricity and that Entergy engrossed and forestalled electricity markets in the state.
