Company Description

Mazama Energy is a geothermal developer that has differentiated technology to deliver and scale superhot rock geothermal. In 2025 Mazama achieved the highest temperature in an engineered geothermal system, 629 °F (331°C), at Newberry, Oregon, unlocking the potential to generate significantly more energy from fewer wells, use less land, water and capital, and thereby, lower the cost of power.
