Java Substation

Java Substation, located in Lancaster Division, is a 34.5-4.8 kV substation with two distribution feeder circuits that serve approximately 1,665 customers. The existing 5 MVA bank has exceeded the nameplate rating and one circuit has significant load growth. The NWA project to postpone the transformer replacement was initiated with an RFP in 2016. If a cost-effective solution is developed, NWA resources to defer the transformer replacement project are expected to be in service by January 2019.

New Gardenville Substation

The New Gardenville Substation, located in the Lancaster Division is composed of two 230/115 kV transformers serving 1,517 customers.  The transformers have experienced low bus voltages and thermal overload.  The traditional wires project is to install a third 230/115 kV transformer at the New Gardenville Substation and operate it in parallel with the two existing transformers.  NYSEG has released an RFP requesting Non-Wire Alternatives solutions for this project. Responses were due February 2, 2018.

Stillwater Substation

Stillwater Substation, located in the Mechanicville Division, is a 2.8 MVA substation transformer that has been near or over its nameplate rating. Approximately 1,270 customers are served by this substation. The traditional wires project is to upgrade the Stillwater Substation with a new 34.5-4.8 X 12.5 kV, 10/12.5 (14) MVA, LTC transformer and convert approximately two miles of distribution circuit to 12.5 kV from the substation to Colonial Drive. NYSEG has released an RFP requesting Non-Wire Alternatives solutions for this project. Responses were due December 1, 2017.

Hilldale Substation

Hilldale Substation, located in the Liberty Division, is composed of three 34.5/12.5kV 10.5MVA substation transformers loaded to near their nameplate rating.  The substation now serves approximately 2,608 customers and significant building and load growth is planned for the area.  The substation has experienced many outages on the 34.5 kV sub transmission line. The traditional wires project is proposed to relieve transformer loading by upgrading the existing substation transformer to a 115/12.5kV 1-12/16/20MVA LTC unit, converting the existing 4.8 kV circuit to 12 kV operation and adding a 2nd 12.5 kV feeder. This transformer will be served off the 115 kV rather than the 34.5 kV transmission system. NYSEG plans to release an RFP requesting Non-Wire Alternatives solutions for this project in 2018.

Orchard Park Substation

Orchard Park Substation, located in the Lancaster Division, is a 34.5-4.8 kV station with three 4.8 kV distribution circuit feeders, serving approximately 3,326 customers.   The existing 9.38 MVA transformer bank has been near to or over its peak nameplate rating. The traditional wires project is to replace the existing 34.5-4.8 kV, 9.38 MVA transformer bank with two new 34.5-4.8×12.5kV, 12/16/20 MVA LTC Transformer Banks, convert the three existing 4.8 kV distribution feeder circuits 285,286,287 to 12 kV operation and establish a fourth 12 kV circuit.  NYSEG plans to release an RFP for NWA solutions in 2018.

Monsey

Capacity relief is needed beginning in 2019 for approximately 0.5 MW to be implemented annually during 2017 to 2019. To further defer traditional infrastructure, approximately 2.5 to 3.0 MW would be needed by 2021, depending on actual future growth. RFP closed on October 24, 2017.

Pomona

O&R has determined that 1.2 MW of load reduction by 2019 will satisfy current circuit contingencies. The present schedule for the projected new business load, in addition to the native load growth in the Pomona area, is expected to require approximately 6.0 MW of load reduction by 2025. RFP closed on February 7, 2018.

West Haverstraw Area – Distribution Circuit Relief

The scope of the Non-Wire Alternatives will be to reduce the loading on three area circuits to improve transfer capability during contingency scenarios.

Station 51 Substation

Station 51 Substation, located north of Rochester in the distribution area, is a reliability improvement project.  The station provides service to customers with significant loading.   If the station transformer were lost the area distribution would not be able to support the load during the summer peak. This project will increase station capacity and develop second source contingency.  RG&E plans to release an RFP requesting Non-Wire Alternatives solutions for this project in 2018.

Station 46 Substation

Station 46 Substation located in an urban area of Rochester in RG&E’s distribution service area, contains two 6.25 MVA transformer banks on which the loading has reached the upper limits of their nameplate ratings.  The station’s six distribution circuits serve approximately 6,356 residential and commercial customers.  Presently, loss of either transformer places the other in a situation where it is loaded well above its rating. The traditional wires project is to replace transformer banks #1 and #3 at Station 46 with two new 34.5-4.16×12.5 kV, 13.4/17.9/22.4 MVA transformer banks.  RG&E plans to release an RFP for Non-Wire Alternatives solutions in 2018.
