About John

For virtually his entire legal career, John Klauberg has represented companies involved in all types of transactional matters in the electric power and gas sectors. For more than 30 years, John has assisted clients in mergers and acquisitions of regulated utilities; acquisitions and dispositions of power generation facilities and similar “utility-type” properties as well as wholesale and retail electric and gas contract portfolios; and various types of joint venture arrangements in the energy space, including those involving both generation and electric transmission facilities. 

John, co-chair of the firm's power projects practice group, has industry transactional experience involving both regulated utilities and unregulated companies, including power trading companies (on both the wholesale and retail level), and has been actively engaged in transactions involving the purchase and sale of energy assets and contract portfolios arising out of some of the largest bankruptcies and restructurings in the independent power sector, including Enron and many others. John also represents numerous parties in renewable and alternative energy transactions, including wind, nuclear and solar, including acquisitions and divestitures and structured transactions, often involving long-term off-take arrangements with utilities or other traditional off-takers or with corporate purchasers.

John has received the highest rankings from Chambers & Partners’ Chambers USA (Band 1) for Energy: Electricity (Transactional) for energy transactional work for several years (2010-2018). He was selected as a 2016 Law360 MVP for transactional work in the electric power area, one of only five attorneys nationwide to be designated. He often serves as speaker at the annual SNL/Platts Utility Mergers & Acquisitions Symposium, as well as other energy industry conferences and seminars.

One client notes: ‘He understands our business better than any other lawyers we work with.’
