Houston energy company to invest $1B in U.S. electric grid manufacturing

grid boost

Hitachi Energy, whose U.S. headquarters is in Houston, has earmarked more than $1 billion to manufacture infrastructure for the U.S. electric grid, which is coping with greater power demand from data centers and AI platforms.

Of that sum, $457 million is dedicated to building a power transformer factory in Virginia. Hitachi Energy said it’ll be the largest facility of its kind in the U.S.

“Power transformers are a linchpin technology for a robust and reliable electric grid and winning the AI race. Bringing production of large power transformers to the U.S. is critical to building a strong domestic supply chain for the U.S. economy and reducing production bottlenecks, which is essential as demand for these transformers across the economy is surging,” said Andreas Schierenbeck, CEO of Switzerland-based Hitachi Energy, which generates revenue of about $16 billion.

The Hitachi announcement aligns with various priorities of the Trump administration. The White House is promoting more U.S.-based manufacturing, more power to accommodate data centers and AI, and greater use of U.S. energy resources.

“If we are going to win the AI race, reindustrialize, and keep the lights on, America is going to need a lot more reliable energy,” U.S. Energy Secretary Chris Wright said.

Texas still has its best solar days ahead of it, even as federal tax credit sunsets

Guest Column

If you follow energy policy, you already know that Congress repealed the 30% residential solar tax credit. This poses a significant challenge for continued growth in the market. It also provides an opportunity for the industry to grow in a smart, consumer-friendly way. That’s why in Texas, the story is what happens next: The state and the market are continuing to make going solar much simpler, better, and cheaper.

Policies are moving in the right direction. For example, starting this month, a bipartisan permitting reform takes effect that will cut red tape for home solar and batteries. It lets licensed third-party professionals review plans and perform inspections, requires agencies to post standardized rules and fees online, and allows homeowners to start work once those third-party approvals are submitted. It also shifts negligence liability to the third-party reviewer, thereby reducing municipal risk while accelerating safe, code-compliant installs. In plain English: fewer bottlenecks, faster installs, and lower “soft costs.”

As a result, Houston is already piloting the National Renewable Energy Lab’s free SolarAPP+ to auto-approve standard solar designs, which cuts roughly 12 days from typical timelines. Independent analyses estimate that these automated permitting rules could trim rooftop solar costs by thousands. In other words, even small, costless policy changes like this can save you almost as much money as the huge solar tax credit did, and these great reforms are happening all the time, and they make the process much more convenient and reliable.

While Texas is making solar simpler, it’s also helping consumers have a good experience when going solar. As of this month, Texas law now also requires solar salespeople to register with the Texas Department of Licensing and Regulation. The same bill standardizes contracts and provides for mandatory disclosures of upfront cost and financing terms. The whole solar industry benefits when customers have a good solar experience. Word of mouth is vital to keeping solar shining.

There's yet another pro-solar Texas law that's also going into effect this month: in addition to SB 1202 (streamlining solar permits) and SB 1036 (regulating solar sales tactics), the legislature is also supporting the dissemination of information about your options when going solar via SB 1697. You can read more about these three brand-new pro-solar state laws here.

The end of the solar tax credit is not the end of the solar industry. Far from it.
