John G. Klauberg

John regularly counsels on transactions involving regulated utilities and unregulated power companies, including owners of competitive power generation assets, as well as power trading companies on both the wholesale and retail levels. He also has been involved in transactions involving the purchase and sale of energy assets and contract portfolios arising from some of the largest bankruptcies and restructurings in the independent power sector.

John also represents clients in renewable and distributed energy transactions—including acquisitions, divestitures, and structured transactions—with matters often involving long-term off-take arrangements with utilities or other traditional off-takers or with corporate purchasers.

Chambers and Partners’ Global and US guides, The Legal 500 US, and IFLR1000 consistently rank John as a leading lawyer in the energy transactions field. In 2016, Law360 named him an MVP of the Year for transactional work in the electric power area, one of only five attorneys nationwide to receive the honor.

Before joining Morgan Lewis, John was co-chair of the power projects practice of a national law firm and previously was co-head of the utilities, power, and pipelines industry sector group of another global law firm.
