Hilldale 115kV source, transformer bank upgrade, 2nd 12kV dist circuit Load Relief 2024 $18,708,000 2018
Orchard Park - Add a 2nd Transformer Bank Load Relief 2025 $8,677,927 2018
Old Fall substation - Install 2nd LTC Transformer Load Relief 2026 $3,500,000 2019
Holland Transformer Replacement Load Relief 2026 $115,306* 2019
Crafts - Add 2nd Transformer and 4th 13.2kV Circuit Position Load Relief 2027 $1,666,009 TBD
West Davenport Sub - Replace sub transformer with non-LTC 7.5/10.5MVA unit Load Relief 2037 $6,503,549 TBD
Sackett Lake Sub - Replace Transformer with 7.5MVA Unit & Convert Distribution to 12.5KV Load Relief 2032 $500,000* TBD

*The costs shown here are only those dollars from the filed CIP for calendar years 2017 - 2021. Capital Plan dollars do not in all cases include the full project cost if additional project expenditures are expected in years 6+.  For example, the Sackett Lake Sub - Replace Transformer project and the Holland Transformer Replacement project total costs are expected to exceed the $1,000,000 Suitability Criteria cost threshold.

**Because the Java Substation project is already in process of securing an NWA, the full project cost is not included in the filed Capital Plan.

Current Projects

Java Substation

Java Substation, located in our 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.

Upcoming Projects

New Gardenville Substation
The New Gardenville Substation, located in our 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.  We plan to release an RFP requesting NWA solutions for this project in Q3 2017.

Stillwater Substation
Stillwater Substation, located in our 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. We plan to release an RFP requesting NWA solutions for this project, in late 2017.

Hilldale Substation
Hilldale Substation, located in our 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. We plan to release an RFP requesting NWA solutions for this project in 2018.

Orchard Park Substation
Orchard Park Substation, located in our 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 34.5-4.8x12.5kV, 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.  We plan to release an RFP for NWA solutions in 2018.
