System Reliability. Notwithstanding any other provisions of this Tariff, the System Operator reserves the right, consistent with Good Utility Practice and on a not unduly discriminatory basis, to effect a Curtailment of Network Integration Transmission Service without liability on the part of the System Operator or the Participants for the purpose of making necessary adjustments to, changes in, or repairs on the Participants' lines, substations and facilities, and in cases where the continuance of Network Integration Transmission Service would endanger persons or property. In the event of any adverse condition(s) or NEPOOL Restated Open Access Transmission Tariff Original Sheet No. 185 disturbance(s) on the NEPOOL Transmission System or on any other system(s) directly or indirectly interconnected with the NEPOOL Transmission System, the System Operator, consistent with Good Utility Practice, also may effect a Curtailment of Network Integration Transmission Service in order to (i) limit the extent or damage of the adverse condition(s) or disturbance(s), (ii) prevent damage to generating or transmission facilities, or (iii) expedite restoration of service. The System Operator will give the Network Customer as much advance notice as is practicable in the event of such Curtailment. Any Curtailment of Network Integration Transmission Service will be not unduly discriminatory relative to the Participants' use of the Transmission System on behalf of their Native Load Customers. The Network Operating Agreement shall specify the rate treatment and all related terms and conditions applicable in the event that the Network Customer fails to respond to established Load Shedding and Curtailment procedures. NEPOOL Restated Open Access Transmission Tariff Original Sheet No. 186 46 Rates and Charges The Network Customer shall pay Transmission Providers for any Direct Assignment Facilities and its share of the cost of any required Network Upgrades and applicable study costs consistent with Commission policy and Schedule 11, along with the payment to the System Operator of the charges for Ancillary Services and the charge for Regional Network Service provided under this Tariff.
