Two New York Utilities Propose Utility-Owned Energy Storage Projects

As part of newly filed rate cases, New York State Electric & Gas Corporation (NYSEG) and Rochester Gas and Electric Corporation (RG&E) (collectively, the Companies), the Companies are seeking authority for utility ownership of four energy storage projects

The Companies propose developing four additional energy storage projects -- two in NYSEG’s territory and two in RG&E’s territory -- providing a total of approximately 12 MW of capacity for load relief and up to 105 MWh of available energy.

All four projects will be interconnected at various intermediate voltage class level (12.47 kV - 4.8 kV) distribution substation locations.

In testimony, the Companies said that it is appropriate for the utilities to own these energy storage projects because, "These projects address multiple substation issues that require significant integration into utility operations and processes while ensuring a safe and reliable distribution system."

"The proposed energy storage solutions are more conducive to utility ownership due to the complex nature of the solution required and the multiple grid benefits being provided," the Companies said
