NYSEG will spend several years rebuilding Dansville substation

A massive rebuild is underway at a decades-old power substation in Dansville as NYSEG kicks off a $122 million upgrade project expected to stretch through the end of the decade.

The Meyer Substation, located on Frontage Road and originally built in 1948, is getting a complete overhaul aimed at improving reliability for about 6,740 customers in the Dansville area—and thousands more across New York who rely on it through NYSEG’s transmission network.


Phase one of the project includes a new transformer and breakers that will boost capacity and reduce outages. That work is expected to be completed and in service by 2026. Phase two will begin in 2027 and wrap up by 2029, adding two more transformers, modern components, and room for future expansion.

“This is a significant substation project that has benefits throughout NYSEG’s service territory,” said Marc Geaumont, president of NYSEG. He said customers should see fewer service interruptions, especially during extreme weather.

NYSEG is owned by Avangrid and says this effort is part of a larger $7 billion investment to modernize critical grid infrastructure across New York by 2030.

The announcement drew praise from local and state leaders, who say grid upgrades like this are essential for growth and development in rural communities. Officials from Livingston and Steuben counties both pointed to the project’s importance in attracting clean tech and supporting local industry.

NYSEG says it invested nearly $880 million in capital projects last year alone and continues to focus on strengthening service for the roughly 1 million customers it serves across the state.
