About the CEATI Transmission & Distribution Conference 2026

‍

Ampacimon will be exhibiting at CEATI's annual Transmission & Distribution Conference in Denver on November 17 and 18, at booth 207. We'll be showing how Dynamic Line Rating (DLR) helps utilities get more capacity out of the transmission lines they already operate. We'll also be on stage with Nova Scotia Power to share what it takes to deploy DLR at scale.

‍

The conference brings together more than 700 utility professionals. Its focus is practical, utility-led approaches to planning, designing, operating and maintaining the power delivery system. Sessions cover grid reliability and resilience, lifecycle management, advanced technologies, system operations, safety, vegetation management, and the integration of new resources and loads.

From Vision to Deployment: Nova Scotia Power's Roadmap for Large-Scale DLR Implementation

‍

• Speakers: Mike MacMillan, Nova Scotia Power, and Luke Howell, Ampacimon
• When: Tuesday, November 17, 3:45 PM
• Session: F3, System Planning, Operations & Protection

‍

Nova Scotia Power and Ampacimon have built North America's largest Dynamic Line Rating deployment, with real-time ratings integrated into NSP's energy management system. In this session, Mike MacMillan and Luke Howell will walk through the roadmap behind it, from the initial vision to deployment across the network.

More capacity from existing transmission lines

‍

Electrification and new loads are adding demand faster than new lines can be permitted and built. Yet most line ratings are still based on assumptions about the weather rather than on measured conditions, and those assumptions are conservative by design.

‍

Dynamic Line Rating bases ratings on the conditions the line actually experiences. That frees up capacity that was already there, reduces congestion costs, and helps defer major reinforcements. Ambient-adjusted ratings are a first step, but they still rely on weather data and a fixed wind assumption. Measuring the line itself captures what weather data can miss, especially the wind actually acting on the conductor.

‍

Inside GridBoost®, our Dynamic Line Rating platform

‍

GridBoost® is the platform our Dynamic Line Rating solutions run on. It hosts three complementary rating strategies that can be deployed on their own or combined across the same network.

‍

Sensor-based DLR: Sensors mounted directly on the conductor measure sag and wind in real time. This delivers up to 40% additional capacity compared with static ratings. The measurement method is patented: sag is derived from the low-frequency mechanical vibrations caused by wind and thermal convection. No calibration, conductor data or tower-mounted weather stations are needed. Sensors can be installed by drone on live lines, without an outage.

‍

OPGW-based DLR: The optical ground wire already strung across your towers becomes the measurement instrument. A single interrogator at substation level measures wind span by span, along up to 2 x 100 km per unit, with nothing added to the conductor. It gives you visibility of the whole route, including the spans that become limiting as conditions change.

‍

Sensorless DLR: On lines with no measurement hardware, weather data alone is used to produce ambient-adjusted ratings at low cost across a wide portion of the network.

‍

Whichever strategy you choose, the platform provides rating forecasts up to 10 days ahead and integrates with EMS, SCADA and market processes. Combining them gives you direct measurement where clearance is critical, distributed measurement across full routes, and ambient-adjusted ratings everywhere else.

Dynamic Line Rating in operation in the US

‍

PPL Electric Utilities was the first US utility to integrate dynamic line ratings into real-time and market operations. The project targeted three historically congested 230 kV lines. Across them, 75 sensors cover 186 km, or about 116 miles.

‍

PPL Electric began monitoring the lines in October 2022. Real-time ratings feed into its central operations system. Hourly day-ahead forecasts go to PJM Interconnection, which uses them in day-ahead analysis. A separate tool compares the sensor-based ratings with a static AAR table, so operators always have a backup reference. The project earned PPL the Edison Electric Institute's Edison Award in 2023

‍

The results:

‍

• Up to 16% more capacity
• A $50 million rebuild avoided
• More than $64 million in congestion costs saved on a single line
• Rates kept low for customers
