Empire State Line
- New 20-mile 345 kV transmission line crossing through five towns in Erie and Niagara counties.
- New 345 kV switchyard (“Dysinger Substation”) at the north end of the transmission line in the Town of Royalton, which is designed to loop in the existing Niagara-Somerset and Niagara-Rochester 345 kV lines.
- The Dysinger substation will feature a 700 MVA phase angle regulator making it the new 345 kV hub in western New York, providing connection for seven 345 kV lines, adding capacity and creating grid efficiencies for transmitting electricity between the Robert Moses Niagara Hydroelectric Power Plant and utility customers throughout Western New York.
- New 345 kV switchyard (“East Stolle Substation”) at the southern terminus of the transmission line in the Town of Elma featuring a new shunt reactor.
- The Empire State Line project’s phase angle regulator will provide additional operational flexibility to the region’s 345 kV system.
Project construction began in March of 2021. The targeted in-service date is June 2022.
The Empire State Line is expected to improve electric reliability across the New York State electric grid and support New York’s goal of maximizing the flow of energy from renewable resources in the region. Furthermore, the line, which will be capable of transmitting approximately 3,700 MW of renewable energy, is expected to save New York customers money by making the grid more efficient.
It will boost the local economy by creating jobs and generating additional revenue for Erie and Niagara counties.
