TerraPower, a nuclear startup funded by Bill Gates, secured a $650 million investment round to construct its inaugural commercial power plant.
Nvidia's venture arm, NVentures, joined the funding, marking its first energy investment, alongside existing investors such as Bill Gates and HD Hyundai.
TerraPower began building its first power plant in Wyoming in June 2024, awaiting permits expected next year, facilitated by the favorable nuclear stance of the Trump administration.
The plant will feature Natrium reactors cooled by molten sodium, enabling more stable operation with excess heat stored for increased demand periods.
The reactors generate 345 megawatts of electricity, bridging the gap between current large reactors and future modular designs, facilitating steady-state operation.
TerraPower's storage system can provide 500 megawatts of electricity for over five hours, aiding in balancing solar and wind power generation.
Initially pursuing a different reactor design, TerraPower shifted to the Natrium design due to uncertainties and expects completion within three years after concrete pouring.
Although the first Natrium reactor might be cost-effective compared to recent U.S. counterparts, the project could amount to $4 billion, with potential Department of Energy funding covering half of the expenses.
