Partners in Israel’s Leviathan natural gas field have agreed to supply gas worth an estimated $190 million to the Ramat Hovav power plant in southern Israel, Delek Drilling said Sept. 24.

Supply of the 1.3 billion cubic meters of gas is expected to begin in December and last for 30 months, or until the Karish and Tanin gas fields begin commercial operation.

Leviathan is Israel’s biggest natural gas field and its partners, in addition to Delek, are Noble Energy and Ratio Oil Exploration.
