# Mazama Energy

> Mazama Energy is a Frisco, Texas geothermal developer building Enhanced Geothermal Systems that tap superhot rock (SHR) - underground formations above 374 C - to deliver low-cost, round-the-clock, carbon-free electricity. Incubated by Khosla Ventures and backed by Gates Frontier, the company reached a world-record 629 F (331 C) bottomhole temperature at its Newberry Volcano pilot in Oregon and aims to produce power at under 5 cents per kWh, with 10x the power density, 75% less water, and 80% fewer wells than conventional geothermal.

- **Founded:** 2023
- **Headquarters:** Frisco, Texas, United States
- **Founders:** AltaRock Energy (Founding company / geothermal EGS expertise), Blade Energy Partners (Founding company / oil & gas drilling expertise), Sriram Vasantharajan (Chief Executive Officer)
- **Team size:** About 22 employees
- **Products:** MUSE (Modular Unconventional Superhot Energy), Mazama Drill, Thermal Lattice, Heat Harvester
- **Notable:** Reached a world-record 629 F (331 C) bottomhole temperature - the hottest enhanced geothermal system ever demonstrated., Completed the first-of-its-kind Superhot Rock EGS pilot in Central Oregon., Drilled up to 2,760 feet through volcanic rock in a single bit run, at peak rates of 100 ft/hour, with zero downhole equipment failures.

## Products & services

- **MUSE (Modular Unconventional Superhot Energy)** — Mazama's integrated platform of proprietary technologies for creating and operating superhot rock geothermal reservoirs.
