Project Challenges:

In support of the REV initiative, New York utilities have been challenged to apply alternative “non-wires” solutions towards achieving their power reliability goals. When RGE/NYSEG faced a need to upgrade its infrastructure in 2016, the utility reached out to TRC experts to discuss a potential battery and inverter energy storage system – as an alternative to the more traditional approach of installing additional transformer banks.

TRC Solutions:

TRC partnered with the utility to assess whether the battery storage could achieve RGE/NYSEG goals: providing additional capacity at the substation level during high demand periods and backup power for a period of 12 hours (enough time to bring in mobile substation).

Our team performed a power system study, through which we:

  • Analyzed existing substation load and establish performance characteristics for the alternative battery storage system;
  • Reviewed vendor-proposed battery/inverter system for performance and risk management;
  • Evaluated potential use of battery/inverter system for active demand reduction/peak shaving;
  • Evaluated operation of substation and feeders for normal and islanded operations; and
  • Evaluated ability of the battery/inverter system to provide safe operation of protection devices.

At study conclusion, TRC provided the utilities with recommendations for the battery and system including modifications to the vendor proposal and utility systems. RGE/NYSEG will be implementing the storage solution over the next several years.

TRC is also developing operational plans for the storage solution, which will enable the utility to optimally maintain the system upon its completion.

Benefits:

Our recommended energy storage solution provided RGE/NYSEG with crucial substation reliability, without the installation of a second costly transformer bank. Further, this project served as a testing ground for the utility – as it sought to explore non-wires options for power system management in terms of long-term costs and benefits. The utility will be able to take the lesson learned from this project and apply them towards other investments going forward.
