Industry is betting big on America’s heartland. Global giants are pouring billions into new data centers, semiconductor plants, EV factories, and more across the Midwest and South, bringing jobs and economic revival to regions long overlooked. But is an aging power grid ready to support this surge in demand?
New Industries in the Heartland
After decades of offshoring, critical industries are now doubling down on U.S. production. Tech companies and manufacturers are migrating to middle America, drawn by affordable land, tax incentives, and access to energy. Semiconductor company TSMC is investing $100 billion in U.S. manufacturing, including chip factories in Arizona. Hyundai has pledged $20 billion toward American onshoring, including a $5 billion steel plant in Louisiana. And Meta recently bought 2,700 acres of farmland for its largest-ever data center, 45 minutes from the Mississippi River.
These projects are part of a larger shift toward domestic manufacturing and tech infrastructure. But these facilities are power hungry. A single hyperscale data center can consume as much electricity as a small city, and semiconductor plants require near-perfect grid reliability. Any disruption can halt production and cost millions.
The problem? Many of these projects are being announced in regions where the grid was designed for much lower energy needs. Electricity demand is growing at its fastest pace in decades, threatening to outstrip supply and strain an already struggling grid.
A Grid in Crisis
According to NERC’s 2024 Long-Term Reliability Assessment, summer demand is projected to grow by more than 122 GW over the next 10 years, increasing current peaks by 15.7%. Over half of the North American continent is at risk of blackouts within the next decade as data centers and electrification continue to drive demand. Yet, transmission infrastructure is struggling to keep pace. Without significant upgrades, heartland states could face bottlenecks, jeopardizing the very projects meant to revitalize their economies.
The issue isn’t just capacity, but reliability. Many of these industries require uninterrupted power, and renewable energy introduces intermittency challenges. Many manufacturers and data centers are looking at things like batteries or natural gas peaker plants, but there is still a huge gap between planned capacity and projected demand.
Closing the Gap
To prevent a crisis, utilities, policymakers, and corporations need to explore solutions—and fast. Things like transmission upgrades and long-range projects need to be prioritized. New technologies, such as advanced grid conductors and dynamic line ratings, could boost existing infrastructure’s capacity by up to 40%, buying time for larger expansions.
Some companies are taking matters into their own hands. Microsoft and Google are experimenting with small modular reactors (SMRs) and other onsite solutions to ensure off-grid power resilience. LS Power is planning to sell gas-fired generation directly to a 300-MW data center in Virginia, a model that could become more common as industries seek to supplement grid power with behind-the-meter solutions.
Keeping Business Booming
If the U.S. fails to modernize its grid, the heartland’s industrial revival could stall before it really even begins. Utilities must balance needed upgrades with cost concerns, exploring innovative rate structures to fund improvements without overburdening consumers.
For policymakers, the challenge is to accelerate permitting and get power where we need it now, not later. As one NERC director John Moura put it, “Our infrastructure is not being built fast enough to keep up with the rising demand. We’re here at a moment where collaboration, urgency and foresight are really non-negotiable.”
