Riot Blockchain Inc., a US-based mining company, decided to create its own electrical substation to obtain higher profits. The company will build a 1.7 gigawatt (“GW”) electrical substation in Navarro County, Texas, to meet the electricity demands of its mining equipment without compromising the city’s power grid. This substation project is already underway. The first phase will kick off with an initial capacity of 400 megawatts (“MW”).
