Meyer Substation in Dansville, New York, first built in 1948, is a NYSEG/Avangrid transmission and distribution substation currently undergoing a US$122 million upgrade. The overhaul project will increase grid capacity and resiliency for roughly 6,740 local customers and also strengthen transmission support across the region. The project is also part of Avangrid’s broader US$20 billion grid modernization plan through 2030, aimed at supporting growing energy demand and improving reliability in the face of extreme weather. On the same note, Avangrid’s landmark transmission project in the northeastern US, New England Clean Energy Connect has also reached a permit milestone ahead of end-year 2025 completion.
Avangrid Begins $122 Mn Overhaul at Meyer Substation in New York
Reported August 27, 2025 – In a crucial move to bolster New York’s increasingly strained power grid, construction has officially commenced on a major overhaul of the Meyer Substation in Dansville under Avangrid. New York State Electric & Gas (NYSEG) is investing $122 million into the project, a direct response to recent reports highlighting growing reliability concerns across the state as older power plants retire and electricity demand surges. This vital initiative is designed to significantly improve energy capacity and enhance grid resiliency. Furthermore, ensure a more reliable power supply for thousands of customers in the Dansville community and the surrounding region.

A Phased Approach to a Modern Grid
The modernization of the Meyer Substation is a meticulously planned, multi-year effort set to unfold in two distinct phases. The first phase, which is now underway, focuses on rebuilding the core of the substation. In addition, this includes the critical replacement of an aging transformer to accommodate modern energy needs, along with the installation of new, state-of-the-art breakers and support structures designed to proactively prevent power outages. This initial stage of construction is a complex undertaking, with a clear target for completion set for 2026. Following this, the project will seamlessly transition into its next phase.
Building for the Future; 2027 and Beyond
Looking ahead, the second phase of construction is scheduled to begin in 2027 and is projected to conclude by 2029. This stage will further expand the substation’s capabilities by adding more transformers. Additionally, strategically reusing a current one to maximize efficiency and value. This comprehensive upgrade is a key component of a much larger strategic vision by NYSEG’s parent company, Avangrid. The Meyer Substation project is part of Avangrid’s planned $20 billion investment through 2030, a massive commitment aimed at modernizing critical grid infrastructure across its service territories to meet the demands of the 21st century.

Why This Upgrade Matters
The urgency of the Meyer Substation project is underscored by a recent report from the New York Independent System Operator (NYISO). The report warned of a potential reliability gap as early as 2025. This is due to the retiring fossil fuel plants and the increase in electricity demand from data centers. Also contributing to the increase is the push for electrification in homes and vehicles. The Dansville substation is a key node in the regional grid, and its modernization is not just about replacing old equipment. It’s about creating a “smarter” grid that can better handle fluctuating power loads. It will also integrate renewable energy sources such as the Cider Solar Farm more effectively. Once upgrade, it will also reduce the frequency and duration of outages for its approximately 20,000 customers.
