GMP is a vertically integrated utility that has Use Rights to a share of the Phase I/II interconnection facility between ISO-NE and Hydro Quebec TransEnergie (“HQT”). GMP uses a portion of the total maximum capacity from this interconnection along with the Highgate and Derby Line interconnection facilities to deliver 259.4 MW of firm power and energy under a long term contract with HQ ("HQ VJO Contract"). The HQ VJO Contract capacity will decrease to 230.0 MW starting 11/1/2012.  The HQ VJO Contract requires purchase by GMP of energy at an annual load factor of 75%. GMP has unused Phase I/II transmission capacityin those hours when GMP does not schedule energy under the HQ VJO Contract and/or when such transmission is not sold under a bilateral contract, subject to actual TTC.

 

HQ Interconnection Services

§  ISO-NE posts daily on behalf of GMP the GMP share of TTC for Phase I/II  based on a 9.26191% share of Phase I/II (combined percentage interest per Restated Use Agreement effective 6/1/2002). The GMP TTC share at maximum is 185.2 based on TTCs of 2000. The Phase I/II share includes interconnection rights of others per a brokering agreement, which is described on a separate posting on the GMP OASIS site.

§  For total TTC for Phase I/II and Highgate, see Hydro Quebec ties , which is updated daily by ISO-NE

§  FERC ordered to reinstate the HQ Interconnection Capacity Credit (HQICC) for the Phase II interconnection. The ICAP treatment of monthly transactions on Phase II has changed starting 6/1/2010. GMP intends to keep its entire share of the HQICC, so that no HQICC is transferred to the Transmission Customer.

§  GMP is only posting Non-Firm Transmission Services on the HQ Phase I/II Transmission Paths.

§  HQ Phase I/II Transmission Paths :

Into ISO-NE : NE/GMP/HQT-ISNE/NEHVDCBORDER-HQ_PHI_OR_II/

Out of ISO-NE: NE/GMP/ISNE-HQT/Q_PHI_OR_II-NEHVDCBORDER/

Other Services

§  Local Network Point-to-Point Service 

GMP posts rates for service over the GMP Subtransmission System, which are non-PTF facilities connecting to the PTF system, generally through the VELCO system, under ISO-NE Open Access RTO Tariff on OASIS. This is found under the unconstrained "NE/GMP/OTHER/Local" path, (ATC = 9999).  

Transmission Service Requests 

§  Transmission Customers of GMP may leave the price field of a transmission service request blank. If left blank, GMP will interpret the request price as that of the current rate posted for the highest cost pathname (interface) used by the request. GMP will reflect this in its seller comments associated with the request. 

§  The OASIS product only allows the posting of weekly offerings on a Monday to Monday basis. Regardless of the postings, transmission customers may request weekly transmission service for any seven (7) consecutive calendar days. To determine whether there is sufficient transmission capacity for such a request, query the daily offerings for the seven days for which service will be purchased.

Transmission Service Reassignment (Resale) 

§  Transmission Customers with Firm Point-To-Point Transmission Service rights may post those rights for resale once for each path (interface) used by the rights. To determine the paths used by the rights go to the ISO-NE Map and observe which paths (interfaces) are crossed only once as one traces their organization's rights from Point of Receipt (POR) to Point of Delivery (POD). Transmission Customers may not post on paths crossed once in each direction. Such rights make no net use of the path in either direction. If the rights do not cross any path only once, the rights may be posted by the customer under the generic interface called "OTHER" (see below).  

§  Regardless of whether a set of rights crosses an interface or not, a transmission customer may post those rights for resale under the generic path called "OTHER". The "OTHER" path represents a generic aggregation of all unrestricted transmission paths across the GMP Transmission System. It is posted with an ATC of "9999" to reflect the fact there is no commercial restriction to short-term commercial transactions unless those transactions use one or more of the posted paths (for example, NY to NE).  

§  As a courtesy for their potential customers, transmission customers posting rights for resale are strongly recommended to post the POR and POD of the rights under the "Seller Comments" of the posting.  

§  If an assignee (the purchaser of rights for resale) desires a change of POR and/or POD (or any other service specification) on a firm basis, it may be necessary for GMP to perform a System Impact Study before such specification changes can be accommodated. The Assignor (the Transmission Customer selling the rights) may request GMP to evaluate the need for a System Impact Study prior to accepting a service request from a customer looking to purchase the assignor's transmission service rights. Requests can be made by contacting GMP at 1-802-747-5534 (during normal business hours: 8 AM - 5:00 PM, non-holiday weekdays). GMP will respond to the inquiry under the "Provider Comments" area of the OASIS (if the transmission service request to the assignor was made on the OASIS) or under the "Want Ads" section of the OASIS (if the transmission service request to the assignor has been made off of the OASIS). If a System Impact Study is required, a study agreement will have to be entered into between the assignee and GMP before such study commences.  

Ancillary Services  

§  Unless specified in a transmission customer's service agreement, transmission customers will not be billed for Transmission Scheduling, System Control and Dispatch Service (T Scheduling) and Reactive Supply and Voltage Control from Generation Sources Service (Reactive). The cost of scheduling, as stated in Schedule 1 of the ISO New England Inc., FERC Electric Tariff No. 3, Section II – Open Access Transmission Tariff, are included with other Tariff charges. The rates for Reactive Ancillary Service are provided in Schedule 2, but GMP does not currently plan to apply this Schedule.  

§  The cost of Generation Scheduling, System Control and Dispatch Service (G Scheduling) from GMP (Schedule 1 of the of ISO New England Inc., FERC Electric Tariff No. 3, Section II – Open Access Transmission Tariff) is included in other charges.  

§  If a transmission customer is transmitting power to a load located on the GMP Transmission System, it may need to purchase Regulation and Frequency Response Service (Regulation), Energy Imbalance Service (Energy Imbalance), Operating Reserve - Spinning Reserve Service (Spinning Reserve) and Operating Reserve - Supplemental Reserve Service (Supplemental Reserve) (See Schedules 3, 4, 5 and 6, respectively, of ISO New England Inc., FERC Electric Tariff No. 3, Section II – Open Access Transmission Tariff).
