Section 1100-2.22 - Exhibit 21: Electric System Effects and Interconnection

Exhibit 21 shall contain:

(a) A detailed description of the proposed electric interconnection, including:

(1) The design voltage and voltage of initial operation;

(2) The type, size, number and materials of conductors;

(3) The insulator design;

(4) The length of the transmission line;

(5) The typical dimensions and construction materials of the towers;

(6) The design standards for each type of tower and tower foundation;

(7) For underground construction, the type of cable system to be used and the designstandards for that system;

(8) For underground construction, indicate on a profile of the line the depth of the cable and the location of any oil pumping stations and manholes;

(9) Equipment to be installed in any proposed switching station or substation including an explanation of the necessity for any such switching station or substation;

(10) Any terminal facility; and

(11) The need for cathodic protection measures.

(b) A system reliability impact study, performed in accordance with the Federal Energy Regulatory Commission-approved Open Access Transmission Tariff (OATT) of the New York Independent System Operator, Inc. (NYISO), available at www.nyiso.com, that shows expected flows on the system under normal, peak and emergency conditions and effects on stability of the interconnected system, including the necessary technical analyses (thermal, voltage, short circuit and stability) to evaluate the impact of the interconnection. The study shall include the new electric interconnection between the facility and the point of interconnection, as well as any other system upgrades required.

(c) An evaluation of the potential significant impacts of the facility and its interconnection to transmission system reliability at a level of detail that reflects the magnitude of the impacts.

(d) A discussion of the benefits and detriments of the facility on ancillary services and the electric transmission system, including impacts associated with reinforcements and new construction necessary as a result of the facility.

(e) An estimate of the increase or decrease in the total transfer capacity across each affected interface, and if a forecasted reduction in transfer capability across affected interfaces violates reliability requirements, an evaluation of reasonable corrective measures that could be employed to mitigate or eliminate said reduction.

(f) A description of criteria, plans, and protocols for generation and ancillary facilities' design, construction, commissioning, and operation, including as appropriate to generation technology:

(1) Engineering codes, standards, guidelines and practices that apply;

(2) Generation facility type certification;

(3) Procedures and controls for facility inspection, testing and commissioning; and

(4) Maintenance and management plans, procedures and criteria.

(g) For facilities where it is contemplated that a portion of a new interconnection substation to be built will be transferred to the transmission owner:

(1) Describe the substation facilities to be transferred and the contemplated future transaction, including a timetable for the future transfer;

(2) Describe how the substation-interconnection design will meet the transmission owner's requirements; and

(3) Define the operational and maintenance responsibilities for the substation and how they will meet the transmission owner's standards.

(h) If the applicant will entertain proposals for sharing above-ground infrastructure with other utilities (communications, cable, phone, cell phone relays, and similar facilities), criteria and procedures for review of such proposals.

(i) A status report on equipment availability and expected delivery dates for major components including towers, turbines, solar panels, inverters, transformers, and related major equipment.
