McLennan Site
Project of Cipher Mining
Where it stands
Cipher Mining's McLennan Site in central Texas targets up to 500 MW with estimated energization in 2028. In February 2026 Cipher exercised its option to acquire the SPE holding the purchase rights and was in the process of exercising those rights to buy the site. No construction or operating capacity is reported in the passages, and there is no newer information after February 2026.
