35.5 Interconnected Operation

35.5.1 Obligation to Remain Interconnected

The Parties shall at all times during the term of this Agreement operate or direct the operation of their respective Transmission Systems so that they remain interconnected except:

35.5.1.1 During the occurrence of an event of Force Majeure which renders a Party unable to remain interconnected;

35.5.1.2 When an Interconnection is opened in accordance with the terms of an Operating Instruction or, if the Operating Instruction does not anticipate a particular circumstance where there is an imminent risk of equipment failure, or of danger to personnel or the public, or a risk to the environment, or a risk to system Security or reliability of a Transmission System, which cannot be avoided through Good Utility Practice; or

35.5.1.3 During planned maintenance where notice has been given in accordance with outage procedures as implemented by the Coordination Committee.

35.5.2 Adherence to Standards Authority Standards, Policies and Procedures

The Parties are participants in multiple Standards Authorities and are required to comply with specified standards, criteria, guides and procedures (“Standards Authority Standards”).  Such Standards Authority Standards detail the many coordinating functions carried out by the parties, and this Agreement is intended to enhance those arrangements.  Such Standards Authority Standards include, and the Parties agree to, the provision of “maximum reasonable assistance” to a neighboring Balancing Authority Area.  Such maximum reasonable assistance will not normally require the shedding of firm load.

35.5.3 Notification of Circumstances

In the event that an Interconnection Facility is opened or if the Interconnection Facility transfer capability is changed, or if a Party plans to initiate the opening of an Interconnection Facility, or to change the transfer capability of the Interconnection Facilities, such Party shall immediately provide the other Party with notification indicating the circumstances of the opening or transfer capability change and expected restoration time, in accordance with procedures implemented by the Coordination Committee.

35.5.4 Compliance with Decisions of the Coordination Committee Direction

PJM shall direct the operation of the PJM Transmission System and the NYISO shall direct the operation of the NYISO Transmission System in accordance with the obligations of their respective tariffs, rules and standards and applicable directions of the Coordination Committee that conform with their respective tariffs, rules and standards, except where prevented by Force Majeure.  The Coordination Committee’s scope includes making decisions and jointly developing and approving Operating Instructions for many expected circumstances within the provisions of the Parties’ respective tariffs, rules and standards.  If decisions of the Coordination Committee do not anticipate a particular circumstance, the Parties shall act in accordance with Good Utility Practice.

35.5.5 Control and Monitoring

Each Party shall provide or arrange for 24-hour control and monitoring of their portion of the Interconnection Facilities.

35.5.6 Reactive Transfer and Voltage Control

The Parties agree to determine reactive transfers and control voltages in accordance with the provisions of their respective Standards Authority Standards.  Real and reactive power will be transferred over the Interconnection Facilities as described in Section 35.11.

35.5.7 Inadvertent Exchanges

Inadvertent power transfers on all Interconnection Facilities shall be controlled and accounted for in accordance with the standards and procedures developed by the Standards Authorities  and the system operators of each Party to this Agreement.

35.5.8 Adoption of Standards

The Parties hereby agree to adopt, enforce and comply with all applicable requirements and standards that will safeguard the reliability of the interconnected Transmission Systems.  Such reliability requirements and Reliability Standards shall be:

35.5.8.1 Adopted and enforced for the purpose of providing reliable service;

35.5.8.2 Not unduly discriminatory in substance or application;

35.5.8.3 Applied consistently to both Parties with the exception of subsection 35.5.8.5 below;

35.5.8.4 Consistent with the Parties’ respective obligations to applicable Standards Authorities including, without limitation, any relevant requirements or guidelines from each of NERC, or its Regional Councils’ or any other Standards Authority or regional transmission group to which either of the Parties is required to adhere; and

35.5.8.5 With respect to the NYISO, consistent with the NYSRC Reliability Rules.

35.5.9 New York - PJM IROL Interface (s)

The Parties will adhere to IROLs that each Party develops in accordance with its respective procedures.[1]    IROLs will be determined as needed to maintain acceptable steady-state and transient performance of the NYISO and PJM Transmission Systems.  Each Party will specify in its procedures the list of interfaces to which IROLs apply.[2]  Each Party will monitor these limits for their respective IROLs in accordance with this Agreement and independently determine the applicable import and export transfer limits.  Each Party agrees to operate the NYISO – PJM interface to the most conservative limits developed in real-time and the day-ahead planning process.  These operating limits shall be determined in accordance with Standards Authority Standards.  Both Parties will take coordinated corrective actions, when requested by either Party, to avoid an exceedance of any IROL identified.  If an exceedance occurs, actions will be taken to clear the exceedance as soon as possible, and in accordance with Standards Authority Standards.

35.5.10 Coordination and Exchange of Information Regarding System Planning

The Parties shall exchange information and coordinate regarding system planning and inter-regional planning activities in a manner consistent with Standards Authority Standards and consistent with the requirements of confidentiality agreements or rules binding upon either of the Parties.
