Hitachi plans to invest $1 billion to expand its U.S. power grid infrastructure manufacturing, its energy unit said on Thursday, as the country faces record electricity demand from Big Tech’s build-out of AI data centers. The U.S. holds the biggest concentration in the world of data centers, which are expected to triple their energy use to consume about 12% of the domestic power supply in less than three years. As a result, many utilities are ramping up spending on the long-stagnating electrical grid. Nearly half of Hitachi Energy’s latest investment, or $457 million, will go towards building a new facility in South Boston, Virginia, to manufacture large power transformers. The facility will be the biggest U.S. producer of the massive transformers, which can run as large as a two-story home, Hitachi said.  Hitachi to invest $1 billion to produce power grid components in US | Reuters
