A pair of Dewey & LeBoeuf defectors now with Akin Gump Strauss Hauer & Feld are advising the Palestinian Power Generation Company (PPGC) on a 20-year, $1.2 billion deal to purchase natural gas from Israel’s Leviathan offshore gas field.

Announced Sunday at the historic American Colony Hotel in Jerusalem, the landmark deal calls for a group of energy companies to begin selling gas from Leviathan to the privately owned PPGC within three years. In turn, the PPGC will build a $300 million natural gas processing plant in the West Bank city of Jenin.
