Liberty Power, an electricity retailer that serves customers in about a dozen states, fired all its employees after suffering deep losses in the Texas freeze, Bloomberg News reported. The company was unable to give employees a 60-day notice because of “events which are outside our control that impacted our ability to predict future revenues to support continued operations,” President Derik Viner told staff late Sunday night in an email seen by Bloomberg News. Liberty Power is the latest power company to take a hit from the cold blast in February that left millions without power and killed more than 100 people. It follows Griddy Energy LLC, which exposed consumers to volatile power prices and quickly went out of business. The main Texas grid operator is still short almost $3 billion in payments from market participants.
