The U.S. electrical grid needs modernization at a speed and scale that requires adoption of technologies beyond status-quo solutions like new and upgraded lines and substations.

The magnitude and rate of change demands that we use technologies capable of timely and flexible deployment at cost-benefit ratios that ensure value to the end-consumers of energy. By making the most of existing grid assets and new investments, we maximize benefits for customers while managing change and diligently delivering reliability.

Dynamic Line Ratings (DLR), which is a system that uses real-time and forecasted conditions to continually calculate the thermal carrying capacity of lines, is just such a technology that flexibly unlocks grid carrying capacity faster and more affordably than status-quo solutions. Some DLR solutions, like that provided by LineVision, provide situational awareness about grid assets beyond the impact of ambient conditions on carrying capacity. The combined value of this DLR solution—improved ratings methodologies for efficient use of existing line carrying capacity and enhanced situational awareness of grid asset performance—improves the cost-benefit ratio for customers, allows for strategic investments and change, and increases grid reliability.

The Case Study shares AES’ experience in selecting DLR and LineVision’s solution as well as the planning for and the execution of deployment of 42 LineVision sensors across five AES transmission lines in Indiana and Ohio, each selected for their diverse characteristics and anticipated customer benefit. The Study summarizes initial results from the DLR system and highlights insights from lessons learned and next steps. The purposes of sharing information through this Case Study are to (a) increase market understanding of the beneficial uses of DLR and (b) accelerate future deployment of the technology throughout the U.S. electrical grid.
