NYSEG Investing in Critical Transmission Infrastructure to Strengthen Reliability Across New York
NYSEG updating more than 230 transmission lines across 800 miles through 2031
Company committed to strengthening system to support the reliable flow of energy across New York
BINGHAMTON, N.Y. — October 20, 2026 — New York State Electric & Gas (NYSEG) is prioritizing transmission upgrades to support a strong and reliable grid throughout New York State with its transmission line deficiencies (TLD) program. In 2026, NYSEG has corrected 200 asset condition issues across 35 transmission lines and is planning to update more than 230 transmission lines spanning approximately 800 miles through 2031.
Transmission lines act as the highway of the electric grid across New York. These high-voltage power lines move large amounts of electricity over long distances from power generation sources to local substations.
“Transmission lines are the backbone of electric infrastructure,” said Marc Geaumont, president of NYSEG. “Any disruption to the transmission network could have a ripple effect for customers. Maintaining this network is one of our key priorities when it comes to energy reliability in New York.”
NYSEG’s TLD program aims to proactively repair or replace infrastructure beyond its useful operating life and helps reduce outage risks for customers. Lines are prioritized based on the condition of the asset and its overall impact on the system if it were to fail. Some of this work includes replacing aging transmission poles, replacing deteriorated crossarms and hardware, and upgrading transmission structures. In 2025, the Company addressed more than 500 asset condition issues across 62 transmission lines. NYSEG’s goal is to address approximately 370 deficiencies by the end of the year.
Strengthening these lines is critical to ensuring the lights stay on for homes and businesses. By modernizing the transmission system, reliability will improve, be stronger during periods of extreme weather, support growing electricity demand, prevent larger and more costly problems, and support economic development in communities across the state.
