New York State Electric & Gas (NYSEG) is to pilot overhead transmission line monitoring to increase capacity and accelerate renewable energy growth.

NYSEG, a subsidiary of Avangrid, is to deploy LineVision’s non-contact LiDAR sensors to introduce dynamic line rating in the Hornell area of New York.

The goal of this ‘non-wires alternative’ is to reduce grid congestion with real-time data to enhance the capacity of the lines.

Traditionally, lines have been operated using ‘static’ line ratings based on fixed values.

However, with the real-time data combining properties such as sag, temperature and the forecast weather conditions, the capacity can be determined on a ‘dynamic’ basis to enable increases in the capacity without potentially large and costly upgrades.

“We know that we have a critical role in building a smarter, more resilient network that will enable us to deliver clean energy to more customers,” commented Patricia Nilsen, president and CEO of NYSEG and RG&E.

“Investments in innovation like this are very exciting because it will benefit our customers in multiple ways.”

The sensors will be installed on two of the company’s transmission lines – one from Elma in Erie County to Strykersville in Wyoming County and the other from Warsaw to Perry in Wyoming County.

Funding for the project was awarded to Avangrid and LineVision through round two of NYSERDA’s Future Grid Challenge programme.

Capacity optimisation is crucial for the large-scale integration of renewable energies, with their potential for congestion.

New York state’s Climate Leadership and Community Protection Act (CLCPA) goals to achieve 70% renewable electricity by 2030 call for an additional 10,000MW solar capacity and 9,000MW offshore wind capacity.

Such an increase would likely cause significant congestion on transmission lines.
