Estimated Costs. The total estimated costs (+30%/-15%) of the work associated with the Attachment Facilities and upgrade facilities required for the interconnection of the Large Generating Facility are presented in the table below. SERVICE AGREEMENT NO. 2475 In addition, the estimated cost for Developer’s share of the Thermal Transfer Limit Upgrades is $3,850,774.00. As described in the Part 1 Facilities Study for the Large Generating Facility, the estimates provided herein exclude: • application fees, • applicable surcharges, • overall project sales tax, • property taxes, • escalation beyond estimated project completion date shown in milestone schedule, • future operation and maintenance costs, SERVICE AGREEMENT NO. 2475 • recurring monthly communications circuits’ charges, if any, responsible by the Developer to the communications utility, • allowance for funds used during construction (AFUDC) assuming Developer upfront payment, • adverse field conditions such as rock, water, weather, and Developer electrical equipment obstructions, • extended engineering and/or construction hours to minimize outage time or National Grid’s public duty to serve, • cost associated with graveling a section of the existing transmission line ROW for construction and maintenance access, • the cost of any temporary construction service, or • any required permits or property acquisitions. Cost adders estimated for overtime will be based on 1.5 and 2 times labor rates if required for work beyond normal business hours. Meals and equipment are also extra costs incurred for overtime labor. Any modifications to the Large Generating Facility, as defined herein, may impact the requirements set forth in this Appendix A and associated cost estimates. The Developer’s responsibility for the costs of any required System Upgrade Facilities or System Deliverability Upgrades that are above the Project Cost Allocation for these facilities identified in the Class Year 2017 Interconnection Facilities Study and accepted by the Developer shall be determined in accordance with Section 25.8.6 of Attachment S of the NYISO OATT.
