WIRES commissioned London Economics International LLC (LEI) to prepare a whitepaper that explores advanced transmission technologies (ATTs) and innovative practices in the U.S. electric grid. Drawing on extensive research, interviews, and a survey of transmission owners and technology providers, the report details the breadth of offerings, the benefits and challenges of their deployment, and presents real-world examples of how these tools are already being deployed by transmission owners to enhance system performance.
As demand on the electric grid intensifies, utilities are responding not only by investing in new infrastructure but also adopting innovative software, hardware, and advanced techniques methods in design, construction, and operations. These solutions are helping to improve reliability, resilience, and cost-effectiveness. While it is important to recognize that ATTs and Innovative Practices are not a substitute for building new transmission lines, they are increasingly seen as critical tools in the toolbox that can complement and support traditional investments by maximizing the capabilities of new and existing assets.
The report offers:
- An overview of the universe of advanced transmission technologies (ATTs) offerings and practices including their core benefits
- Case studies showcasing successful deployments and key lessons learned;
- Recommendations for policymakers and regulators to help facilitate adoption of these technologies – ranging from support for collaborative pilot projects, adoption of long-term planning frameworks, better information sharing, regulatory innovation, and realignment of financial incentives.
Together these insights aim to help transmission owners and stakeholders evaluate and implement ATT+ solutions more effectively – supporting the development of a more modern, resilient, and cost-effective electric grid.
