Ormat Technologies has appointed Aron Willis and Daniel Moelk to senior roles, enhancing operational leadership and geothermal drilling capabilities.
Ormat Technologies, Inc. has announced two strategic senior management appointments to support its continued growth in geothermal energy and advanced drilling technologies. The company welcomed Aron Willis as Executive Vice President, Electricity Segment, and Daniel Moelk as Senior Vice President, Resources, Drilling & EGS.
Effective June 4, 2025, Aron Willis assumes leadership of Ormat’s Electricity Segment.
