6.12Schedule 12 - Rate Mechanism for the Recovery of the Highway Facilities Charge (“HFC”)

6.12.1Applicability

6.12.1.1This Schedule establishes the Highway Facilities Charge (“HFC”) for the recovery of that portion of the costs related to Highway System Deliverability Upgrades (“Highway SDUs”) required for deliverability under Section 25.7.12 of Attachment S of the ISO OATT that are allocated to Load Serving Entities (“LSEs”). This Schedule shall not apply to: (i) the extent that a Highway SDU is addressed and funded as part of a transmission project undertaken in accordance with the Comprehensive System Planning Process pursuant to Attachment Y of the ISO OATT; (ii) costs for System Upgrade Facilities or System Deliverability Upgrades that are allocated to Developers or Interconnection Customers in accordance with Attachments S, X or Z of the ISO OATT; (iii) costs of transmission expansion projects undertaken in connection with an individual request for Transmission Service under Sections 3.7 or 4.5 of the ISO OATT; (iv) transmission facilities eligible for cost recovery pursuant to another rate schedule of the ISO OATT; and (v) transmission facilities for which costs are recovered through the Transmission Service Charge (“TSC”) or the NYPA Transmission Adjustment Charge (“NTAC”) determined in accordance with Attachment H of the ISO OATT.

6.12.1.2The HFC shall be calculated in accordance with the formula in Section 6.12.3 using the revenue requirement related to each Highway SDU filed with the Commission by a Transmission Owner pursuant to Section 6.12.2 and approved or accepted by the Commission. The costs that may be included in the revenue requirement for calculating the HFC include all reasonably incurred costs, as determined by the Commission, related to the development, construction, operation and maintenance of any Highway SDU undertaken pursuant to Attachment S of this tariff (including costs for a Highway SDU that is subsequently halted through no fault of the constructing Transmission Owner) that are allocated to LSEs.  These costs include, but are not limited to, a reasonable return on investment and any incentives for the construction of transmission projects approved under Section 205 or Section 219 of the Federal Power Act and the Commission’s regulations implementing those sections.  The HFC established under this Schedule shall be separate from the TSC and the NTAC determined in accordance with Attachment H of the ISO OATT, and any charge for transmission facilities eligible for cost recovery through another rate schedule of the ISO OATT.

6.12.2Recovery of Transmission Owner’s Costs Related to Highway SDUs

Each Transmission Owner shall file with the Commission the rate treatment, prior to the implementation of any HFC, that will be used to derive and determine the revenue requirement to be included in the HFC for Highway SDUs undertaken pursuant to a Class Year Deliverability Study and allocated to LSEs in accordance with Section 25.7.12 of Attachment S of the ISO OATT.  The rate treatment will provide for the recovery of the full revenue requirement for that portion of a Highway SDU that is allocated to LSEs consistent with the provisions of Attachment S and this Rate Schedule.  Pursuant to a determination by the ISO that the threshold for construction of a Highway SDU has been crossed in accordance with Section 25.7.12.3.1 of Attachment S of the ISO OATT, the Transmission Owner(s) responsible for constructing the Highway SDU will proceed with the approval process for all necessary federal, state and local authorizations for the requested project to which this HFC applies.

6.12.2.1Upon receipt of all necessary federal, state, and local authorizations, including Commission approval or acceptance of the rate treatment, the Transmission Owner(s) shall commence construction of the project.

6.12.2.2The portion of the cost of the Highway SDU to be allocated to LSEs will be reduced by any Headroom payments made to the constructing Transmission Owner by a subsequent Developer or Interconnection Customer prior to the completion of the project.

6.12.2.3The period for cost recovery will be determined by the Commission and will begin if and when the Highway SDU for which a portion of the costs thereof are recovered pursuant to this Rate Schedule 12 enters service, is halted, or as otherwise determined by the Commission.  The Transmission Owner(s) will make a filing with the Commission to provide for its review and approval or acceptance of the final project cost and resulting revenue requirement to be recovered through the HFC pursuant to this Rate Schedule 12The Transmission Owner(s) shall bear the burden of resolving all concerns about the content of the filing that might be raised in such proceeding.  The ISO will begin to calculate and bill the HFC in accordance with the period for cost recovery determined by the Commission after the Commission has accepted or approved the filing.

6.12.3Calculation and Recovery of HFC and Payment of Recovered Revenue

The HFC is to be invoiced by the ISO separately for each Highway SDU for which a portion of the costs thereof are recovered pursuant to this Rate Schedule 12 and paid by the LSEs allocated in accordance with Section 25.7.12.3.2 of Attachment S of the ISO OATT.    The ISO shall collect the HFC from LSEs.  The LSEs,, including Transmission Owners, non-Transmission Owner LSEs, municipal systems, competitive LSEs and any other LSE, to which the costs of the Highway SDU have been allocated (each a “Responsible LSE”) will be invoiced by the ISO and shall pay the HFC.

6.12.3.1The revenue requirement filed by the Transmission Owner pursuant to this Schedule and approved or accepted by the Commission, as may be subsequently adjusted in accordance with Section 6.12.4.1.3 below, will be the basis for the HFC that shall be charged by the ISO to each Responsible LSE for the Billing Period based on the Responsible LSE’s proportionate share of the ICAP requirement in the statewide capacity market, adjusted to subtract locational capacity requirements, as set forth in Section 25.7.12.3.2 of Attachment S of the ISO OATT.

6.12.3.2The HFC for the Billing Period shall include operation and maintenance costs for the proportionate share of the Highway SDU funded by LSEs.

6.12.3.3LSEs will not be responsible for actual costs in excess of their share of the final Class Year estimated cost of the Highway SDU if the excess results from causes within the control of a Transmission Owner(s) responsible for constructing the Highway SDU as described in Section 25.8.6.4 of Attachment S of the ISO OATT.

6.12.3.4As described in Section 25.7.2.2 of Attachment S of the ISO OATT, the Transmission Owner(s) responsible for constructing a Highway SDU for which a portion of the costs thereof are recovered pursuant to this Rate Schedule 12 shall request Incremental TCCs with respect to the Highway SDU in accordance with the requirements of Section 19.2.4 of Attachment M.  As it relates solely to a Highway SDU for which a portion of the costs thereof are recovered pursuant to this Rate Schedule 12, the Transmission Owner(s) responsible for constructing the Highway SDU shall not be a “Transmission Owner” for purposes of Section 20.2.5 or Section 20.3.7 of Attachment N of the ISO OATT.  Accordingly, the Transmission Owner(s) responsible for constructing the Highway SDU shall not receive Net Congestion Rents pursuant to Section 20.2.5 of Attachment N of the ISO OATT or Net Auction Revenues pursuant to Section 20.3.7 of Attachment N of the ISO OATT as it relates to a Highway SDU for which a portion of the costs thereof are recovered pursuant to this Rate Schedule 12.

6.12.3.4.1The Transmission Owner(s) responsible for constructing a Highway SDU shall exercise its right to obtain and maintain in effect all Incremental TCCs they are awarded with respect to the Highway SDU, as further described in Section 25.7.2.2 of Attachment S of the ISO OATT.  The Incremental TCCs awarded with respect to a Highway SDU may not be sold or transferred through a Centralized TCC Auction, Reconfiguration Auction or the Secondary Market.  The Transmission Owner(s) responsible for constructing a Highway SDU for which a portion of the costs thereof are recovered pursuant to this Rate Schedule 12 shall receive congestion payments pursuant to Section 20.2.3 of Attachment N of the ISO OATT for any Incremental TCCs related to the Highway SDU for which it is the Primary Holder.  The congestion payments received by the Transmission Owner(s) responsible for constructing a Highway SDU from any Incremental TCCs it holds related to the Highway SDU will be used in the calculation of the HFC.  The HFC and adjustments related to Incremental TCCs shall not require and shall not be dependent upon any reopening or any review of : (i) the Transmission Owner’s revenue requirements for the HFC for another Highway SDU for which a portion of the costs thereof are recovered pursuant to this Rate Schedule 12; (ii) the Transmission Owner’s revenue requirements for the TSCs and NTAC set forth in Attachment H of the ISO OATT; or (iii) the Transmission Owner’s revenue requirements for the charge for a transmission facility eligible for cost recovery pursuant to another rate schedule of the ISO OATT.

6.12.3.4.2As it relates solely to a Highway SDU for which a portion of the costs thereof are recovered pursuant to this Rate Schedule 12, the Transmission Owner(s) responsible for constructing the Highway SDU shall receive outage charges for any Incremental TCCs related to the Highway SDU it holds pursuant to Section 19.2.4.10 of Attachment M of the ISO OATT for any hour in the Day-Ahead Market during which the Highway SDU is modeled to be wholly or partially out of service as an entity not subject to Section 20.2.5 of Attachment N of the ISO OATT with respect to the Highway SDU.  Accordingly, the Transmission Owner(s) responsible for constructing the Highway SDU for which a portion of the costs thereof are recovered pursuant to this Rate Schedule 12 shall not be charged or paid O/R-t-S Congestion Rent Shortfall Charges, U/D Congestion Rent Shortfall Charges, O/R-t-S Auction Revenue Shortfall Charges, U/D Auction Revenue Shortfall Charges, O/R-t-S Congestion Rent Surplus Payments, U/D Congestion Rent Surplus Payments, O/R-t-S Auction Revenue Surplus Payments or U/D Auction Revenue Surplus Payments pursuant to Attachment N of the ISO OATT.

6.12.3.5Cost Recovery Methodology

The HFC for the Billing Period shall be based on the ICAP requirement in the statewide capacity market, adjusted to subtract locational capacity requirements for those LSEs determined to be allocated the costs of the project in accordance with Section 25.7.12 of Attachment S of the ISO OATT.

6.12.3.5.1The ISO shall calculate each LSE’s share of the HFC for each Billing Period (i.e., LSE HFC Allocationp,l,B) as follows:

LSE HFC Allocationp,l,B  =  (Billing Period HFCp,B -  IncrementalTransmissionRightsRevenuep,B+ Outage Cost Adjustmentp,B) x (LSE ICAP Allocation %l,B)

Where:

l = the relevant Responsible LSE;

p = an individual Highway SDU for which a portion of the costs thereof are recovered pursuant to this Rate Schedule 12;

B= the relevant Billing Period;

Billing Period HFCp, B = the pro-rata share of the annual HFC for Highway SDU p, as discussed in Section 6.12.2 above and as may be adjusted in accordance with Section 6.12.4.1.3 below, allocated for Billing Period B;

LSE ICAP Allocation %l,B =  the LSE’s proportionate share of the NYCA ICAP requirement for Billing Period B, adjusted to subtract Locational ICAP requirements for Billing Period B, which shall be calculated as: 

(LSE total ICAP Requirement – Sum of LSE Locational ICAP Requirements for any Locality not located within another Locality)/(NYCA Minimum Installed Capacity Requirement – Sum of Locational Minimum Installed Capacity Requirements for any Locality not located within another Locality) 

Such ICAP requirements shall be the ICAP equivalent of the LSE’s UCAP requirements prior to any reduction for Locality Exchange MW;

IncrementalTransmissionRightsRevenuep,B = Congestion payments received by the applicable Transmission Owner for Billing Period B pursuant to Section 20.2.3 of Attachment N of the ISO OATT for any Incremental TCCs held by the Transmission Owner related to the Highway SDU p, as discussed in Section 6.12.3.4.1 above; and

Outage Cost Adjustmentp,B = the Outage charges for any Incremental TCCs held by the Transmission Owner related to the Highway SDU p determined pursuant to Section  6.12.3.4.2 above for any hour in the Day-Ahead Market during which the Highway SDU p is modeled to be wholly or partially out of service aggregated across all hours of Billing Period B.

6.12.3.5.2The ISO will collect the appropriate HFC revenues each Billing Period and remit those revenues to the appropriate Transmission Owner(s) in accordance with the ISO’s billing and settlement procedures.

6.12.3.5.3Billing true-ups to account for load shifting between LSEs will be based upon the existing ICAP methodology, as appropriate.  These true-ups will occur on a monthly basis pursuant to ISO procedures.

6.12.4Headroom Accounting

As new generators and merchant transmission facilities come on line and use the Headroom created by a prior Highway SDU, the Developers or Interconnection Customers of those new facilities will reimburse prior Developers or Interconnection Customers or will compensate the LSEs who funded the Highway SDU Headroom in accordance with Sections 25.8.7 and 25.8.8 of Attachment S of the ISO OATT.

6.12.4.1The Developer or Interconnection Customer of the subsequent project shall make a lump sum payment to the constructing Transmission Owner(s) proportional to the electrical use of the Headroom in the account by the Developer’s or Interconnection Customer’s project.

6.12.4.1.1Payment shall be made as soon as the cost responsibilities of the subsequent Developer or Interconnection Customer are determined in accordance with Attachment S of the ISO OATT.

6.12.4.1.2Payment to the constructing Transmission Owner(s) will be based upon the depreciated amount of the Highway SDU in the constructing Transmission Owner’s accounting records.

6.12.4.1.3The constructing Transmission Owner(s) will adjust their revenue requirement under this Rate Schedule 12 to account for any payments received from subsequent Developers or Interconnection Customers to lower the HFC charged to LSEs going forward and notify the ISO of the adjusted revenue requirement.
