Helping Fervo Energy Deliver 24/7 Clean Power
Summary
Fervo Energy, a U.S. energy technology company focused on next-generation geothermal power, partnered with Virginia Transformer to deliver a main power transformer (MPT) for its Cape Station Phase I, Fervo’s first commercial-scale geothermal project in Utah. The custom-engineered transformer will enable the delivery of 100 MW of firm geothermal power to the grid, supporting long-distance transmission to California, and accelerating the transition to 24/7 clean energy.
The Challenge: Delivering 100 MW of Firm Power - Reliably and On Schedule and Prepping for More
For Cape Station Phase I, scheduled to go online this year, Fervo requires a highly reliable main power transformer capable of stepping up and transmitting 100 MW of geothermal power, with Phase II planned for 2028 to expand total capacity to 400–500 MW. In a market where energy demand is always growing, transformer availability, performance, and delivery timing are critical to maintaining the project’s commissioning schedule.
The Approach: A Custom Main Power Transformer from Virginia Transformer
Virginia Transformer Corporation engineered and manufactured a large 340 MVA power transformer with an on-load tap changer (OLTC) on the high-voltage side, specifically tailored to Cape Station’s utility-scale geothermal requirements. Designed for long service life, dependable performance, and seamless grid integration, the unit helps ensure the reliable delivery of firm renewable power to the grid.
Results: Enabling Reliable, Long-Distance Clean Power
- Transformer shipped on schedule to Cape Station in Beaver County, Utah
- Helps enable delivery of 100 MW of firm geothermal power and support additional energy generation at the site
- Supports long-distance transmission to contracted California offtakers
- Positions Cape Phase I for on-time commissioning and grid connection
A Shared Commitment to Engineering Excellence
As electricity demand surges and grid reliability becomes increasingly critical, this project demonstrates how close collaboration and engineering excellence can overcome infrastructure constraints. The successful delivery of this transformer brings Cape Station Phase I one step closer to providing reliable, 24/7 carbon-free energy to the grid.
