New Transmission Technologies Gaining Traction as Power Demand Challenges Electric Grid

States Adopt New Transmission Technologies to Meet Power Demand

As states across the U.S. confront mounting demands for electricity, innovative transmission technologies are beginning to take center stage in policy discussions. Led by organizations such as The Pew Charitable Trusts, these advancements are seen as vital to modernizing an aging infrastructure that has struggled to keep pace with contemporary energy needs.

The power grid functions similarly to a highway, delivering electricity from generation sources like solar farms and power plants to end-users. Unfortunately, much of the existing transmission infrastructure is outdated, often exceeding its intended lifespan. Experts assert that failure to upgrade could jeopardize grid reliability as energy consumption continues to grow rapidly.

During a recent webinar hosted by The Pew Charitable Trusts, Yaron Miller highlighted the urgent need for states to adopt Advanced Transmission Technologies (ATTs.) These technologies consist of both software and hardware tools that can be deployed swiftly to augment the capacity of transmission lines. While constructing new transmission lines is critical, it often takes up to a decade to complete. In contrast, ATTs can enhance grid efficiency and reliability in a much shorter timeframe.

Benefits of Advanced Transmission Technologies

Kelt Wilska, a consultant from Grid Strategies, discussed various types of ATTs that can help ease grid congestion. One of these is topology optimization, which reroutes electricity away from overcrowded lines. Another promising technology is the dynamic line rating system, which uses sensors to account for real-time weather conditions, allowing grid operators to safely increase electricity flow. Additionally, high-performance conductors—crafted with advanced materials—can amplify wire capacity by 50% to 110%.

During the seminar, Indiana state Senator Eric Koch and Virginia Delegate Phil Hernandez detailed the legislative measures they've championed to accelerate the deployment of ATTs in their respective states. Over the past few years, at least 16 states have implemented laws to promote the use of these technologies, with Connecticut, Indiana, Louisiana, New Mexico, Ohio, Oregon, South Carolina, and Utah all embracing new policies in 2025.

Legislative Measures to Promote ATT Adoption

In Virginia, Senate Bill 862, advocated by Hernandez, mandates that utilities conduct thorough evaluations of ATTs when formulating integrated resource plans (IRPs)—key documents outlining strategies for future energy demands. This law also requires utilities to justify the exclusion of ATTs in their plans, fostering an environment of accountability and transparency among energy providers.

Similarly, Indiana's legislation—unanimously passed by state lawmakers in 2025—compels utilities to incorporate ATTs in their IRPs. The state takes an additional step by allowing cost recovery for utilities investing in these technologies, effectively enabling them to earn a partial return on investments up front. This structure aims to provide the financial assurance necessary for quicker implementation.

Both Koch and Hernandez expressed optimism about the future of ATT technologies, urging other states to recognize their importance in resolving energy challenges. They jointly stated, “We need power, we need it to be affordable, and we need it to be reliable.” The urgency of their message calls for collaboration among legislators and energy stakeholders to brainstorm innovative solutions.

Conclusion

As more states initiate dialogues surrounding the adoption of Advanced Transmission Technologies through legislation and regulatory frameworks, the potential for a modernized and reliable power grid becomes increasingly attainable. This convergence of policy and technology promises significant benefits, not just for utilities but for consumers and families whose livelihoods depend on consistent and affordable energy. The situation calls for a collective effort to leverage every viable idea as society stands on the brink of a renewed energy landscape.
