Common use of System Deliverability Upgrades Clause in Contracts

System Deliverability Upgrades. The least costly configuration of commercially available components of electrical equipment that can be used, consistent with Good Utility Practice and Applicable Reliability Requirements, to make the modifications or additions to the existing New York State Transmission System that are required for the proposed project to connect reliably to the system in a manner that meets the NYISO Deliverability Interconnection Standard for Capacity Resource Interconnection Service. System Upgrade Facilities – The least costly configuration of commercially available components of electrical equipment that can be used, consistent with good utility practice and Applicable Reliability Requirements to make the modifications to the existing transmission system that are required to maintain system reliability due to: (i) changes in the system, including such changes as load growth and changes in load pattern, to be addressed in the form of generic generation or transmission projects; and (ii) proposed interconnections. In the additions to the existing New York State Transmission System that are required for the proposed project to connect reliably to the system in a manner that meets the NYISO Minimum Interconnection Standard. Tariff – The NYISO’s Open Access Transmission Tariff, as filed with the FERC, and as amended or supplemented from time to time, or any successor tariff. Upgrades – The required additions and modifications to the Connecting Transmission Owner’s portion of the New York State Transmission System or the Distribution System at or beyond the Point of Interconnection. Upgrades may be System Upgrade Facilities or System Deliverability Upgrades Distribution Upgrades. Upgrades do not include Interconnection Facilities or Jointly Owned Interconnection Facilities. Attachment 2 Detailed Scope of Work, Including Description and Costs of the Small Generating Facility, Interconnection Facilities, and Metering Equipment Equipment, including the Small Generating Facility, Interconnection Facilities, and metering equipment shall be itemized and identified as being owned by the Interconnection Customer, or the Connecting Transmission Owner. The NYISO, in consultation with the Connecting Transmission Owner, will provide a best estimate itemized cost, including overheads, of its Interconnection Facilities and metering equipment, and a best estimate itemized cost of the annual operation and maintenance expenses associated with its Interconnection Facilities and metering equipment.

A. PROJECT DESCRIPTION Plant Address: 0000 Xxxxxxx Xxxxxxxx Xxxxxxxxxx, XX 00000 The Interconnection Customer constructed a 20 MW wind generation facility in the towns of Lackawanna and Hamburg, New York interconnecting to the existing NG-NM Bethlehem Steel 115 kV buses on the Gardenville 149 and 150 Lines via a 115 kV service lateral connection and the existing Station 11A which the Interconnection Customer took ownership of (“Collection Station”). The Project consists of eight (8) Clipper Liberty 2.5 MW wind turbines operating at 0.690 kV with output stepped up to 13.8 kV through individual pad mount 2.5 MVA transformers. Two 13.8 kV feeders brings the combined power output of the 8 units to the Collection Station where it connects to the 13.8kV side of the transformer TB A1101, is stepped up to 115 kV via the 25/33/41.6 MVA 115/13.8Y kV (11.2% impedance) and 25/33/41.6 MVA 115/13.8Y kV (11.3% impedance) transformers (TB A1101 and TB A1102, respectively), and then brought to the Bethlehem Steel 115 kV bus on the Gardenville 149 and 150 lines. The Collection Station is also used to provide service to Mittal Steel, a load customer of the Connecting Transmission Owner. The Point of Interconnection (“POI”) for the Project is defined as the Bethlehem Steel 115 kV Bus on the Gardenville 149 and 150 Lines.
