Milbank, Tweed, Hadley & McCloy and Latham & Watkins had the lead roles on a $1.17 billion financing to build a geothermal power plant in northern Indonesia.

Two Japanese companies—trading house Itochu Corp. and utility Kyushu Electric Power—are leading a consortium developing the plant that also includes PT Medco Power Indonesia and Israeli renewable energy company Ormat Technologies Inc. The consortium is also working with Indonesian state-owned Pertamina Geothermal Energy, which will take a 10 percent stake in the project.
