Transmission Information and Services for the Phase I/II HVDC-TF Intertie with Hydro-Québec ("Value-added" pages supported by ISO New England Inc.) - - -
An
Overview of the Phase I/II HVDC-TF Facilities
The
Phase I/II HVDC-TF is a 690/2,000 MW HVDC tie line in New England that is
an interconnection to the Hydro-Québec Control Area in the Province of
Québec. This multi-terminal
HVDC line has two termination points in New England (with paired operation
with complementary facilities in Québec). The specific facilities in New
England are: 1.
Phase
I: The Monroe HVDC Terminal,
which interconnects Northern New Hampshire and the Des Cantons HVDC
terminal of Hydro-Québec and, 2.
Phase
II: The Sandy Pond HVDC
Terminal, which interconnects Central Massachusetts and the Nicolet and/or
Radisson HVDC terminals of Hydro-Québec. Each termination
facility (Phase I and Phase II) has the capability to either import or
export energy between the two control areas, and thus each facility has a
Total Transfer Capability (TTC) in both directions. Note, however, that only one of
the two facilities can be in service at a time. ISO New England, Inc. is
responsible for the derivation of the TTC for these facilities. For imports into New England, the
Nominal TTC is 690 MW for Phase I and 2,000 MW for Phase II. In accordance with the Department
of Energy permit to operate the Phase II facilities, depending upon system
conditions in other control areas (particularly NYISO and PJM), the Phase
II TTC for imports into New England could be assigned a value less than
its Nominal TTC. The
Interconnection Rights Holders (IRH) are the entities that pay for and
hold exclusive Use Rights to the transmission capacity of the Phase I/II
HVDC-TF. Each IRH has a
certain share of the rights to use, or make available for use by others,
the Phase I/II HVDC-TF.
Posting of transmission service information on OASIS is required
for "any public utility that owns, operates, or controls facilities used
for the transmission of electric energy in interstate commerce." The subset of IRH that are public
utilities post their individual share of TTC for the facilities on the ISO
New England OASIS node. These
IRH are referred to as Schedule 20A Service Providers and they provide
Phase I/II HVDC-TF transmission service under Schedule 20A to Section II of the ISO
Tariff. The
offerings of certain Schedule 20A Service Providers may also include the
shares of other IRH (i.e., IRH that are not Schedule 20A Service
Providers). Each Schedule 20A
Service Provider is also obligated to post Firm/non-Firm Available
Transfer Capability (ATC) for its share of the Phase I/II HVDC-TF on its
Transmission Provider Page (TPP) on the ISO OASIS. ISO New England Inc. is not
responsible for the posting of ATC for the Phase I/II
HVDC-TF. IRH
Percentage Share and Transmission Service
Offerings
The
list of all IRH, including those that are Schedule 20A Service Providers,
and their respective Phase I and Phase II Percentage Interest and Combined
Percentage Interest MW share of the 2,000 MW Nominal Transfer Capability
of the Phase II tie, is provided in an accompanying
table. This table is presented in three
(3) sections: (A) the IRH that are Schedule 20A Service Providers offering
service over the Phase I/II HVDC-TF pursuant to Schedule 20A to Section II
of the ISO Tariff; (B) the IRH offering their share of the Phase I/II
HVDC-TF through a Schedule 20A Service Provider listed in section (A); and
(C) the IRH who are not currently offering their share of the Phase I/II
HVDC-TF. Clicking on the
highlighted Schedule 20A Service Provider will bring you directly to their
TPP on the ISO OASIS website where an eligible customer can query and
obtain Phase I/II HVDC-TF transmission services. You must acquire an
advanced reservation for transmission service from a Schedule 20A Service
Provider in order to move energy into or out of the New England Control
Area over the Phase I/II HVDC-TF. IRH Percentage Interest of Phase I/II HVDC-TF

This

ISO New England, Inc. These
TTC values reflect projections for the total facility and do not reflect
each individual IRH’s share of the TTC (see ATC offerings below for
offerings of individual IRH).

These
links will display a composite table showing the Available Transfer

transmission service for each Schedule20A Service Provider offering Phase
I/II HVDC-TF service. These tables, updated every fifteen (15)
minutes, show the amounts of Phase I/II HVDC-TF transmission service that
remain available after the updated TTC and existing sales of transmission
service have been taken into account. Clicking on the highlighted
Schedule 20A Service Provider company name in the column header of this
page is an alternative way to get to that provider’s Transmission Provider
Page (TPP), where an Eligible Customer can query and obtain Phase I/II
HVDC-TF transmission services.

Customers
wishing to move energy into or out of the Province of Québec over the
Phase I/II facilities owned by Hydro-Québec must purchase electric energy
transmission service under Hydro-Québec TransÉnergie’s Open Access
Transmission Tariff. Visit the TransÉnergie OASIS site. Transfer
Agreement Information and Notification Form (for IRH Use
Only)
An
IRH may enter into a Transfer Agreement to transfer their Phase I and
Phase II Percentage Interest to another entity. If such a Transfer Agreement is
entered into, the ISO must be notified. The following link will display
the Transfer Agreement Information and Notification Form (TA-1 Form) that
must be completed and submitted to ISO New England in order for the ISO to
recognize and process the transfer.
Additional information and requirements are listed on the TA-1
Form. To view a copy of the
