Hitachi to Invest $1 Billion to Produce Power Grid Components in US by Laila Kearney

William Attardi on September 5, 2025

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

Hitachi Energy plans to invest $106 million to expand its manufacturing operation in Alamo, Tenn., creating 100 jobs to become the second-largest employer in Crockett County. The expansion will expand the company’s capacity to produce transformer components, supporting energy infrastructure and grid modernization, says Steve McKinney, head of transformers for Hitachi Energy in North America.

The Statue of Liberty was made with copper but due to oxidation, it turned green.

When the “Lady in the Harbor” first arrived in New York in 1886, she didn’t look like the mint-green icon we know today. In fact, for the first twenty years of her life, she stood as a towering, metallic beacon of reddish-gold. Designed by French sculptor Frédéric Auguste Bartholdi and engineered by Alexandre Gustave Eiffel, the statue was a gift from France to America. To build her, Bartholdi chose copper for three practical reasons:

  • Malleability:It could be hammered into elaborate, thin sheets.
  • Weight:Copper is lighter than stone or bronze, making it easier to ship 350 individual pieces across the Atlantic.
  • Durability:It was strong enough to survive a 27-day ocean voyage and the harsh winds of the harbor.

When she was unveiled on October 28, 1886, her skin—made of 300 copper sheets roughly the thickness of two pennies—shone with a bright, metallic brown luster. The transformation from “penny-colored” to “patina-green” wasn’t planned. Bartholdi actually expected the statue to age into a deeper, darker red. However, the unique environment of New York Harbor—a mix of salt air, moisture, and industrial pollution—triggered a process called oxidation.

The Timeline of Change:

  1. 1886–1900:The bright copper dulled into a dark, muddy brown.
  2. 1903:The first hints of a light green crust, or “patina,” began to appear.
  3. 1906:The color change was so controversial that Congress nearly stepped in. They appropriated $62,000 to paint the statue back to its original color, but the public protested, calling the idea “sacrilege.”
  4. 1910–1920:The statue was a patchy mix of brown and green until 1920, when the oxidation was complete, leaving her entirely teal.

While we now view the green color as iconic, it actually serves a vital structural purpose. The layer of verdigris (the green patina) acts as a protective shield. It seals the copper underneath, preventing the metal from further corrosion and weathering.  By the time the color fully changed, a new generation of immigrants had arrived in America seeing a green statue.
