TeraWulf (WULF) has started operations at its Nautilus Cryptomine facility, the first nuclear-powered bitcoin mining facility in the United States, with nearly 8,000 mining rigs online, representing computing power, or hashrate, of approximately 1.0 exahash per second (EH/s). According to a press release issued on Monday, the company expects another 8,000 rigs to be activated in the coming weeks, bringing capacity at the Nautilus facility in Pennsylvania to 1.9 EH/s by May. TeraWulf’s energy costs will be significantly reduced by Nautilus, which has secured a power agreement for 2 cents per kilowatt hour (kWh) of power for five years, bringing its average energy cost down to around 4 cents/kWh across its two facilities.
