Below please find a list of National Grid NWA opportunities and their status. Clicking on the hyperlink for each opportunity brings you to National Grid’s System Data Portal. When you land there, click on the ellipse icon on the far right and then click on “DER Opportunity Documents.” National Grid also encourages you to explore and use other areas of the System Data Portal.
Baldwinsville
Substation MWh1 violation — Includes two substations and 5-6 overloaded feeders. The Sorrell Hill Substation currently exceeds the National Grid Distribution Planning Guidelines for Load at Risk and the Lysander Substation is nearing the point at which it will exceed this guideline as well. This opportunity is closed; solutions are being evaluated.
Old Forge
Area of poor reliability – looking to NWA to solve summer loading and reliability problems. Radial Sub-transmission line (46kV) that runs through the Adirondack park in the Mohawk Valley Region of National Grid’s territory. This opportunity is closed; solutions are being evaluated.
Brooklea Dr/Fayetteville
Loading on the step-down “ratio” transformer bank serving portions of the Village of Fayetteville has increased to a level that the step-down “ratio” transformer bank is overloaded during peak loading days. The area being considered for a NWA solution is located in Central New York southeast of the City of Syracuse. Relieve an overloaded step-down ratio bank on a Duguid Distribtuion feeder. 13.2kV WYE to 4.16kV WYE. This opportunity is closed; solutions are being evaluated.
Gilbert Mills
Loading on the Gilbert Mills substation serving the Towns of Schroeppel, Palermo and portion of Hastings has increased to a level at which that is projected to be overloaded to 100% of its normal rating. A single transmission or distribution (“T&D”) contingency results in approximately 1.7MVA load at risk. National Grid is evaluating alternatives to reduce the area load in order to maintain or improve reliability performance. This opportunity is closed; solutions are being evaluated.
Van Dyke
Loading on the substations serving portions of the Towns of Bethlehem and New Scotland and portions of the City of Albany has increased to a level at which the load at risk for a single transmission and distribution (“T&D”) contingency exceeds the risk threshold established in National Grid’s Distribution Planning Criteria. Additionally, 11.5MW of expected new commercial and industrial load in the Town of Bethlehem will cause feeder loading beyond normal ratings. National Grid is evaluating alternatives to serve this new load and to reduce the area load at risk to maintain or improve reliability performance. Responses were due January 19, 2018.
Golah-Avon
Golah – N Lakeville lines 216 and 217 projected to be above 100% of its summer emergency rating during a single contingency. Load relief is required to keep voltage within allowed criteria. Responses were due January 19, 2018.
Buffalo 53
Loading on Station 53 has increased to a level at which the capacity of the transformers and cables feeding the station exceed the threshold established in the National Grid Distribution Planning Criteria. National Grid is commencing evaluations of non-wires solutions including but not limited to demand response or distributed generation (Distributed Energy Resources “DER”) to reduce loading on existing cables and transformers to prevent overload conditions. Responses were due January 19, 2018.
FAIRDALE DSUB
Loading on the Fairdale substation serving the Town of Hannibal has increased to a level at which that is projected to be overloaded to 100% of its normal rating. National Grid is evaluating alternatives to reduce the area load in order to maintain or improve reliability performance. Responses were due October 8, 2018.
NEW CICERO SUBSTATION DSUB & D-LINE
In the North Syracuse area, there are significant capacity and outage exposure issues that need to be resolved. Two major substations that need to be relieved are the Pine Grove Substation and the Bartell Road Substation. In addition to the relief needed at these two existing substations, there are existing distribution feeders with thermal overloads that need to be addressed. Estimated RFP timing is Q1-Q2 2018.
BYRON F1863 – REBUILD /RECONDUCTOR
Looking to Increase capacity on existing feeder to enable stronger tie capabilities with neighboring feeder. Also, improve voltage conditions on the input side of several regulators which will improve their performance and reduce operational wear. Estimated RFP timing is Q2 2018.
NORTH BANGOR CONVERSION (D-LINE)
North Bangor is a single ended 34.5/4.8kV distribution substation. MWh violations are the main driver for this project. There are limited ties in the area and upon failure at North Bangor sub it would be difficult to carry the load long term. Estimated RFP timing is Q2 2018.
BUFFALO 23KV RECONDUCTOR – HUNTLEY2
Load Relief for underground sub-transmission cables beyond summer emergency ratings based on load projections. Estimated RFP timing is Q2 2018.
LHH – MALLORY 34.5 KV 22 LINE REG.
Sub-Transmission (34.5kV) voltage criteria violation during N-1 contingency events. Low voltage on stations on this Sub-T line during contingency events. Load relief and voltage support required. Estimated RFP timing is Q2 2018.
WATERTOWN NEW 115/13.2 KV SUBSTATION
Substation MWh violation — Includes one substation with two transformer banks in violation of the MWh violation, as well as 2 feeders approaching thermal limits. The Coffeen Substation currently exceeds the National Grid Distribution Planning Guidelines for Load at Risk. Estimated RFP timing is Q2 2018.
FORBES AVE – NEW SUBSTATION & D-LINE L
Loading on the substation and Sub-transmission lines serving the city of Rensselaer has increased. The Rensselaer station is a single bank station, with limited 13.2kV feeder ties. Additionally, 18MW of expected new commercial load in the City of Rensselaer will cause distribution feeder / sub-transmission, and station transformer loading beyond normal ratings. National Grid is evaluating alternatives to serve this new load and to reduce the area load at risk to maintain or improve reliability performance. Estimated RFP timing is Q2 2018.
SONORA WAY FEEDER
The NWA ask is to defer the construction of a new feeder at Sonora Way Station. The new feeder will be located in the Geneseo area. National Grid is evaluating alternatives to serve this new load and to reduce the area load at risk to maintain or improve reliability performance. Estimated RFP timing is Q2 2018.
