Transmission Is the Missing Link in America's Energy Future

For years, conversations about America’s energy future have largely focused on generation. How do we build more power? How do we meet growing demand? How do we ensure reliability?

Those questions remain important. But increasingly, the challenge isn’t simply producing enough electricity. It’s delivering that electricity where and when it’s needed.

As demand rises from data centers, advanced manufacturing, electrification, and population growth, transmission is one of the most important pieces of infrastructure in the country. Yet it’s also one of the most overlooked.
The reality is the United States simply isn’t building enough transmission.

A modern economy depends on the ability to move electricity efficiently across long distances. Yet in many parts of the country, the transmission system is aging, congested, and struggling to keep pace with changing patterns of supply and demand. The result is a growing disconnect between where power is generated and where it is needed most.

This isn’t a challenge unique to any one energy source. Transmission benefits every form of generation. Whether electricity comes from natural gas, nuclear, hydropower, wind, or solar, it provides the pathway that allows those resources to serve customers and support economic growth. Without sufficient transmission capacity, even the most reliable generating resources can’t deliver their full value.

The economic case is equally compelling. Grid congestion costs consumers billions of dollars each year, raising electricity prices and increasing costs for businesses. Study after study has shown that major transmission investments deliver benefits that significantly exceed their costs.

At the same time, policymakers and regulators should examine whether today’s regulatory frameworks fully reward the most efficient investments. Traditional utility models have often favored building new infrastructure over maximizing the performance of existing assets. Updating those incentives to value efficiency, performance, and capacity gains alongside new construction could unlock faster, lower-cost solutions while continuing to support utility investment.

But transmission is about more than economics. As extreme weather events become more frequent and electricity demand continues to skyrocket, a stronger and more interconnected grid provides flexibility and resilience. When one region faces generation shortfalls or unusually high demand, transmission allows power to flow from neighboring areas, improving reliability and reducing the risk of outages.

Transmission is also a critical factor in America’s competitiveness. The industries driving future economic growth depend on reliable and affordable electricity. Companies cannot invest with confidence if energy infrastructure cannot keep pace with demand.

At the same time, the global competition to build that infrastructure is accelerating. During the 2020s alone, China has completed more than 8,200 miles of ultra-high-voltage transmission lines, while the United States has built only about 375 miles of comparable high-voltage infrastructure. The contrast highlights a broader reality: energy infrastructure remains foundational to economic strength.

The lesson isn’t that America should copy another country’s approach. It’s that every major economy understands a simple truth: modern infrastructure underpins growth, competitiveness, and energy security.

The good news is that solutions already exist. New transmission lines remain essential, but technologies such as dynamic line ratings, advanced sensors, and high-performance conductors can also unlock additional capacity on the existing grid, often faster and at lower cost.

Realizing this potential will require policy to keep pace with technology. Streamlining permitting, improving long-term interregional planning, and creating regulatory incentives that reward both expanding the grid and getting more from existing infrastructure can significantly accelerate progress. America doesn’t have to choose between building new transmission and making better use of what we already have. We need both.

Meeting future demand will require an all-of-the-above approach that leverages every available source of reliable power. But regardless of where that power comes from, it must be able to reach the homes, businesses, factories, and communities that depend on it.

If the United States wants to lead the next era of economic growth, we must invest not only in producing more power, but also in delivering it.
