VELCO is proud to have earned the Great Place To Work® Certification™, strengthening its status as one of the top employers in the region. This recognition is based on the Great Place To Work Trust Index survey, where VELCO employees shared their workplace experiences.
The tariff information on this page is historical. No service has been provided by VELCO since June 30, 2006, when VELCO transferred all its transmission facilities to Vermont Transco LLC (VTransco). VTransco provides service over such facilities pursuant to applicable tariffs, including Schedule 21–VTransco.
On February 14, 2011, VELCO filed a Notice of Cancellation of its Local Service Schedule, Schedule 21-VELCO, which is part of ISO-New England's FERC Electric Tariff No. 3 with the Federal Energy Regulatory Commission (FERC).
On February 24, 2011, VELCO made an Amendment to Filing to Correct Requested Proposed Effective Date in connection with its Notice of Cancellation of Schedule 21–VELCO. The effective date for cancellation is April 1, 2011. FERC issued a Letter Order on April 1, 2011, approving the cancellation of Schedule 21–VELCO.
Effective February 1, 2005, ISO-NE began operating as the Regional Transmission Organization (RTO) for New England. Transmission owning companies, as signatories to the Transmission Operating Agreement became Participating Transmission Owners (PTOs) in this RTO. The governing document for providing transmission service in New England is the ISO New England Transmission, Markets and Services Tariff (ISO-NE Tariff). Section II of the ISO-NE tariff, the ISO-NE Open Access Transmission Tariff or OATT, provides the rates, terms and conditions for transmission service over the regional transmission system. Schedule 21 of Section II of the ISO-NE Tariff provides the rates, terms and conditions associated with providing transmission service over the PTOs’ local transmission facilities. (Point-to-Point Service over the Phase I/II HVDC Transmission Facilities is provided for under Schedule 20a, as outlined in separate Business Practices for Schedule 20A.)
To apply for service over the system please go to the Rates, Tariffs and Business Practices page of Vermont Transco LLC.

Review 9/18/2014
Vermont Electric Power Company, Inc. (VELCO) and Vermont Transco LLC (VT Transco) (collectively, Companies) set forth below their procedures and plan (Procedures) for implementing the Federal Energy Regulatory Commission’s (the Commission) Order 717 relating to the Standards of Conduct for Transmission Providers. VELCO and Vermont Transco are Transmission Providers under Order 717.
VELCO is a corporation organized and existing under the laws of the State of Vermont, with its principal place of business in Rutland, Vermont. VELCO’s headquarters is located at 366 Pinnacle Ridge Rd, Rutland, Vermont 05701.
VELCO was the nation’s first statewide transmission-only utility, organized in the late 1950s to develop an integrated high-voltage transmission system that would interconnect electric utilities throughout the State of Vermont and provide access to low-cost power from the St. Lawrence River Project in New York. Over the ensuing decades, VELCO expanded its facilities and service to meet the needs of the Vermont distribution utilities who were both customers and owners.
In 2006, Vermont Transco LLC (VT Transco) was formed as a limited liability company for the purpose of acquiring and owning VELCO’s existing transmission assets and any new transmission facilities to be developed in Vermont. As described in the petition to FERC seeking authorization for the transfer of assets from VELCO to VT Transco (Docket No. EC06-115-000), the transaction allowed VT Transco to become the owner of Vermont’s transmission system. VELCO contributed almost all of the transmission facilities that it owned directly to VT Transco in exchange for membership units in VT Transco. In return, VELCO became the managing member of VT Transco, operating the transmission assets under the terms of a management services agreement. Thereafter, the Vermont distribution utilities contributed cash in exchange for membership units, thereby creating an ownership structure that closely paralleled VELCO’s.
The purpose of the transaction was to establish a more modern business entity that would be able to raise capital more effectively and efficiently. It also helped reduce rates to customers. Otherwise, the transaction was intended to be seamless for customers and regulators: i.e., the terms and conditions of services provided by VELCO and VT Transco, taken together, would be the same as the terms and conditions of services provided by VELCO prior to the transaction. VT Transco now provides service over such facilities pursuant to applicable tariffs, including Schedule 21-VT Transco, accepted by and on file with the Commission, to all of the electric distribution utilities in Vermont and also to certain distribution utilities in New Hampshire.
VELCO does not own any generation assets; it is a “wires only” company. VELCO does not sell any retail electric energy to its customers. VELCO does not have an Energy Trading function, but it does have a power accounting department. This department is responsible for administration of the settlement contracts for a few of the distribution utilities. The power accounting department is involved in the settlement only portion of the markets. It does not provide market advice or transmission-related information to the Vermont distribution utilities. Therefore, VELCO’s power accounting department is not a “marketing function,” and does not include “marketing function employees,” under Order No. 717.
VT Transco is an electric transmission company operating under the laws of the State of Vermont. VT Transco through its manager, VELCO, serves the distribution utilities and other eligible customers in the State of Vermont. The headquarters is located at 366 Pinnacle Ridge Rd, Rutland, Vermont 05701. VT Transco does not own any generation assets; it is a “wires only” company. VT Transco does not sell any retail electric energy to its customers.1 VT Transco does not have any employees. VT Transco’s manager. VELCO, employs personnel that operate the transmission assets of VT Transco under the terms of a management services agreement between VT Transco and VELCO. Therefore, VELCO has transmission function employees.
Green Mountain Power Corporation (GMP) is a Vermont electric distribution utility that owns more than 10% of VT Transco and more than 10% of VELCO. Therefore, this Vermont electric distribution utility is considered an Affiliate of both VT Transco and VELCO for purposes of the Order 717 Standards of Conduct. Accordingly, VELCO and VT Transco apply the Standards of Conduct to marketing function employees of this utility.
Green Mountain Power Corporation is a Vermont electric distribution utility that owns more than 10% of VT Transco and more that 10% if VELCO. Therefore, it is an Affiliate of both VT Transco and VELCO

Information on this complies with FERC requirements to post information about Available Transmission Capacity, Transmission Reliability Margin, and Total Transfer Capacity.
Effective: April 1, 2011
Version: Original
[1] §37.6(b) Posting transfer capability. The available transfer capability on the Transmission Provider’s system (ATC) and the total transfer capabiity (TTC) of that system shall be calculated and posted for each Posted Path as set out in this section.
ISO is the regional transmission organization (RTO) for the New England Control Area. The New England Control Area includes the transmission system located in the states of Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. The New England Control Area is comprised of PTF, non-PTF, OTF, MTF, and is interconnected to three neighboring Balancing Authority Areas (“BAA”) with various interface types.
As part of its RTO responsibilities, the ISO is registered with the North American Electric Reliability Corporation (“NERC”) as several functional model entities that have responsibilities related to the calculation of ATC as defined in the following NERC Standards: MOD-001 – Available Transmission System Capability (“MOD-001”), MOD-004 – Capacity Benefit Margin (“MOD-004”), and MOD-008 – Transmission Reliability Margin Calculation Methodology (“MOD-008”). The extent of those responsibilities is based on various Commission approved transmission operating agreements and the provisions of the ISO New England Operating Documents.
Pursuant to CFR § 37.6(b)[1] of the FERC Regulations Transmission Provider’s are obligated to calculate and post TTC and ATC for each Posted Path.
Posted Path is defined as any control area to control area interconnection; any path for which service is denied, curtailed or interrupted for more than 24 hours in the past 12 months; and any path for which a customer requests to have ATC or TTC posted. For this last category, the posting must continue for 180 days and thereafter until 180 days have elapsed from the most recent request for service over the requested path. For purposes of this definition, an hour includes any part of any hour during which service was denied, curtailed or interrupted.
VTransco does not currently have a Posted Paths based on the above definition. However to extent that VTransco does in the future have a Posted Path VTransco will calculate TTC using NERC Standard MOD-029-1 Rated System Path Methodology as outlined below.Basic information on ATC and TTC may be found on VT Transco’s website at: www.vermonttransco.com.
CBM is defined as the amount of firm transmission transfer capability set aside by a TSP for use by the Load Serving Entities. The ISO does not set aside any CBM for use by the Load Serving Entities, because of the New England approach to capacity planning requirements in the ISO New England Operating Documents. Load Serving Entities operating within the New England Control Area are required to arrange for their Capacity Requirements prior to the beginning of any given month in accordance with ISO Tariff, Section III.13.7.3.1 (Calculation of Capacity Requirement and Capacity Load Obligation). Load Serving Entities do not utilize CBM to ensure that their capacity needs are met; therefore, CBM is not applicable within the New England market design. Accordingly, for purposes of ATC calculation, As long as this market design is in place in New England, the CBM is set to zero (0). VTransco provides local transmission service over its non-PTF facilities that are connected to ISO-NE and the Vermont distribution utilities. VTransco does not reserve CBM for these paths, and the CBM is presently set to zero.
The ETCF are those confirmed Firm transmission reservation (PTPF.) plus any rollover rights for Firm transmission reservations (RORF) that have been exercised. There are no allowances necessary for Native Load forecast commitments (NLF), Network Integration Transmission Service (NITSF), grandfathered Transmission Service (GFF) and other service(s), contract(s) or agreement(s) (OSF) to be considered in the ETCF calculation.
The (ETCNF) are those confirmed Non-Firm transmission reservations (PTPNF). There are no allowances necessary for Non-Firm Network Integration Transmission Service (NITSNF), Non-Firm grandfathered Transmission Service (GFNF) or other service(s), contract(s) or agreement(s) (OSNF).
The Transmission Reliability Margin (TRM) is the portion of the TTC that cannot be used for the reservation of firm transmission service because of uncertainties in system operation conditions and the need for operating flexibility to ensure reliable system operation as system conditions change. It is used only for external interfaces under the New England market design. Since VTRANSCO provides transmission service over its non-PTF facilities that are connected only to the internal New England system, VTRANSCO does not reserve TRM for these paths, and the TRM is presently set to zero.
NERC Standards MOD-001-1 – Available Transmission System Capability and MOD-029-1 – Rated System Path Methodology defines the required items to be identified when describing a transmission provider’s ATC methodology.
As a practical matter, the ratings of the radial transmission paths are always higher than the transmission requirements of the Transmission Customers connected to that path. As such, transmission services over these posted paths are considered to be always available.
Common practice is not to calculate or post firm and non-firm ATC values for the non-PTF assets described above, as ATC is positive and listed as 9999. Transmission customers are not restricted from reserving firm or non-firm transmission service on non-PTF facilities.
As Real-Time approaches, the ISO utilizes the Real-Time energy market rules to determine which of the submitted energy transactions will be scheduled in the coming hour. Basically, the ATC of the non-PTF assets in the New England market is almost always positive. The ATC is equal to the amount of net energy transactions that the ISO will schedule on an interface for the designated hour. With this simplified version of ATC, there is no detailed algorithm to be described or posted other than: ATC equals TTC. Thus, for those non-PTF facilities that serve as a path for the VTransco Schedule 21Vermont Transco Point-to-Point Transmission Customers, VTransco has posted the ATC as 9999, consistent with industry practice. ATC on these paths varies depending on the time of day. However, it is posted with an ATC of "9999" to reflect the fact that there are no restrictions on these paths for commercial transactions.
For purposes of this Attachment A PH is any period before the Operating Horizon. Consistent with the NERC definition, ATCF is the capability for Firm transmission reservations that remain after allowing for TRM, CBM, ETCFPostbacksF and counterflowsF.
As discussed above, TRM and CBM are zero. Firm Transmission Service over Schedule 21-Vermont Transco that is available in the Planning Horizon (PH) includes: Yearly, Monthly, Weekly, and Daily. PostbacksF and counterflowsF of Schedule 21-Vermont Transco transmission reservations are not considered in the ATC calculation. Therefore, ATCF> in the PH is equal to the TTC minus ETCF
For purposes of this Attachment A OH is noon eastern prevailing time each day. At that time, the OH spans from noon through midnight of the next day for a total of 36 hours. At that time progresses the total hours remaining in the OH decreases until noon the following day when the OH is once again reset to 36 hours.
Consistent with the NERC definition, ATCFis the capability for Firm transmission reservations that remain after allowing for ETCF, CBM, TRM, PostbacksF and counterflowsF.
As discussed above, TRM and CBM is zero. Daily Firm Transmission Service over Schedule 21Vermont Transco is the only firm service offered in the Operating Horizon (OH). PostbacksF and counterflowsF of Schedule 21-Vermont Transco transmission reservations are not considered in the ATCF calculation. Therefore, ATCF in the OH is equal to the TTC minus ETCF.
Because Firm Schedule 21-Vermont Transco transmission service is not offered in the Scheduling Horizon (SH): ATCF in the SH is zero.
ATCNF is the capability for Non-Firm transmission reservations that remain after allowing for ETC F , ETCNF, scheduled CBM (CBMS), unreleased TRM (TRMU), Non-Firm Postbacks (PostbacksNF) and Non-Firm counterflows (counterflowsNF).
As discussed above, the TRM and CBM for Schedule 21-Vermont Transco are zero. Non-Firm ATC available in the PH includes: Monthly, Weekly, Daily and Hourly. TRM U, PostbacksNF and counterflowsNF of Schedule 21-Vermont Transco transmission reservations are not considered in this calculation. Therefore, ATCNF in the PH is equal to the TTC minus ETC F and ETCNF.
ATCNF available in the OH includes: Daily and Hourly.
As discussed above TRM and CBM for Schedule 21-Vermont Transco are zero. TRMU, counterflows and ETCNF are not considered in this calculation. Therefore, ATCNF in the OH is equal to the TTC minus ETC F, plus postbacks of PTPF in OH as PTPNF (PostbacksNF)
As stated above, the ratings of the radial transmission paths are always higher than the transmission requirements of the Transmission Customers connected to that path. As such, transmission services over these posted paths are considered to be always available.
For those non-PTF Vermont Transco facilities that are primarily radial paths that provide transmission service to directly interconnected generators it is possible, in the future, that a particular radial path may interconnect more nameplate capacity generation than the path’s TTC. However, due to the ISO’s security constrained dispatch methodology, the ISO will only dispatch an amount of generation interconnected to such path so as not to incur a reliability or stability violation on the subject path. Therefore, ATC in the PH, OH and SH may become zero, but will not become negative.
As described above, the ATC values for VTransco’s non-PTF utilized for internal Point-to-Point transmission service are always positive, and are thus set at 9999. The ATC values for these internal posted paths are posted in accordance with NAESB standards on VTransco’s provider page of the ISONE OASIS website Common practice is not to calculate or post firm and non-firm ATC values for the non-PTF assets described above, as ATC is positive and listed as 9999. Transmission customers are not restricted from reserving firm or non-firm transmission service on non-PTF facilities.
When any of the variables in the ATC equations change, the ATC values are recalculated and immediately posted.
Schedule 21-Vermont Transco non-PTF has no external interfaces. Therefore it is not necessary to coordinate the values.
A link to the actual mathematical algorithm for the calculation of ATC for VTransco’s non-PTF internal interfaces is located on VTransco’s website.
Introduction and background
ISO is the regional transmission organization (RTO) for the New England Control Area. The New England Control Area includes the transmission system located in the states of Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. The New England Control Area is comprised of PTF, non-PTF, OTF, MTF, and is interconnected to three neighboring Balancing Authority Areas (“BAA”) with various interface types.
As part of its RTO responsibilities, the ISO is registered with the North American Electric Reliability Corporation (“NERC”) as several functional model entities that have responsibilities related to the calculation of ATC as defined in the following NERC Standards: MOD-001 – Available Transmission System Capability (“MOD-001”), MOD-004 – Capacity Benefit Margin (“MOD-004”), and MOD-008 – Transmission Reliability Margin Calculation Methodology (“MOD-008”). The extent of those responsibilities is based on various Commission approved transmission operating agreements and the provisions of the ISO New England Operating Documents.
Pursuant to CFR § 37.6(b)[1] of the FERC Regulations Transmission Provider’s are obligated to calculate and post TTC and ATC for each Posted Path.
Mathematical Algorithms | ||
| Planning Horizon | ATCF = (TTC-CBM-TRM-ETCF) | ATCNF = (TTC-CBM-TRM- ETCF- ETCNF ) |
| Operating Horizon | ATCF = (TTC-CBM-TRM-ETCF) | ATCNF = (TTC-CBM-TRM- ETCF- ETCNF + PostbacksNF) |
| Scheduling Horizon | ATCF = 0 | ATCNF = TTC |
Posted Path is defined as any control area to control area interconnection; any path for which service is denied, curtailed or interrupted for more than 24 hours in the past 12 months; and any path for which a customer requests to have ATC or TTC posted. For this last category, the posting must continue for 180 days and thereafter until 180 days have elapsed from the most recent request for service over the requested path. For purposes of this definition, an hour includes any part of any hour during which service was denied, curtailed or interrupted.
VTransco does not currently have a Posted Paths based on the above definition. However to extent that VTransco does in the future have a Posted Path VTransco will calculate TTC using NERC Standard MOD-029-1 Rated System Path Methodology as follows:
CBM is defined as the amount of firm transmission transfer capability set aside by a TSP for use by the Load Serving Entities. The ISO does not set aside any CBM for use by the Load Serving Entities, because of the New England approach to capacity planning requirements in the ISO New England Operating Documents. Load Serving Entities operating within the New England Control Area are required to arrange for their Capacity Requirements prior to the beginning of any given month in accordance with ISO Tariff, Section III.13.7.3.1 (Calculation of Capacity Requirement and Capacity Load Obligation). Load Serving Entities do not utilize CBM to ensure that their capacity needs are met; therefore, CBM is not applicable within the New England market design. Accordingly, for purposes of ATC calculation, As long as this market design is in place in New England, the CBM is set to zero (0). VTransco provides local transmission service over its non-PTF facilities that are connected to ISO-NE and the Vermont distribution utilities. VTransco does not reserve CBM for these paths, and the CBM is presently set to zero.
The ETCF are those confirmed Firm transmission reservation (PTP F.) plus any rollover rights for Firm transmission reservations (ROR F ) that have been exercised. There are no allowances necessary for Native Load forecast commitments (NLF), Network Integration Transmission Service (NITSF), grandfathered Transmission Service (GFF) and other service(s), contract(s) or agreement(s) (OSF ) to be considered in the ETC F calculation.
The (ETCNF) are those confirmed Non-Firm transmission reservations (PTPNF) There are no allowances necessary for Non-Firm Network Integration Transmission Service (NITSNF), Non-Firm grandfathered Transmission Service (GFNF) or other service(s), contract(s) or agreement(s) (OSNF).
The Transmission Reliability Margin (TRM) is the portion of the TTC that cannot be used for the reservation of firm transmission service because of uncertainties in system operation conditions and the need for operating flexibility to ensure reliable system operation as system conditions change. It is used only for external interfaces under the New England market design. Since VTRANSCO provides transmission service over its non-PTF facilities that are connected only to the internal New England system, VTRANSCO does not reserve TRM for these paths, and the TRM is presently set to zero.

For purposes of this Attachment A PH is any period before the Operating Horizon. Consistent with the NERC definition, ATCF is the capability for Firm transmission reservations that remain after allowing for TRM, CBM, ETCF , PostbacksF and counterflowsF. As discussed above, TRM and CBM are zero. Firm Transmission Service over Schedule 21-Vermont Transco that is available in the Planning Horizon (PH) includes: Yearly, Monthly, Weekly, and Daily. PostbacksF and counterflowsF of Schedule 21-Vermont Transco transmission reservations are not considered in the ATC calculation. Therefore, ATCF in the PH is equal to the TTC minus ETCF
For purposes of this Attachment A OH is noon eastern prevailing time each day. At that time, the OH spans from noon through midnight of the next day for a total of 36 hours. At that time progresses the total hours remaining in the OH decreases until noon the following day when the OH is once again reset to 36 hours.

PostbacksF and counterflowsF of Schedule 21-Vermont Transco transmission reservations are not considered in the ATCF calculation. Therefore, ATCF in the OH is equal to the TTC minus ETC F. Because Firm Schedule 21-Vermont Transco transmission service is not offered in the Scheduling Horizon (SH): ATCF in the SH is zero.
ATCNF is the capability for Non-Firm transmission reservations that remain after allowing for ETC F , ETCNF, scheduled CBM (CBMS), unreleased TRM (TRMU), Non-Firm Postbacks (PostbacksNF) and Non-Firm counterflows (counterflowsNF). As discussed above, the TRM and CBM for Schedule 21-Vermont Transco are zero. Non-Firm ATC available in the PH includes: Monthly, Weekly, Daily and Hourly. TRM U, PostbacksNF and counterflowsNF of Schedule 21-Vermont
Transco transmission reservations are not considered in this calculation. Therefore, ATCNF in the PH is equal to the TTC minus ETC F and ETCNF.
ATC NF available in the OH includes: Daily and Hourly. As discussed above TRM and CBM for Schedule 21-Vermont Transco are zero. TRMU, counterflows and ETCNF are not considered in this calculation. Therefore, ATC NF in the OH is equal to the TTC minus ETC F, plus postbacks of PTPF in OH as PTPNF (Postbacks NF).
As stated above, the ratings of the radial transmission paths are always higher than the transmission requirements of the Transmission Customers connected to that path. As such, transmission services over these posted paths are considered to be always available. For those non-PTF Vermont Transco facilities that are primarily radial paths that provide transmission service to directly interconnected generators it is possible, in the future, that a particular radial path may interconnect more nameplate capacity generation than the path’s TTC.

This is VTransco's Capacity Benefit Margin Implementation Document (“CBMID”)
The Transmission Reliability Margin (TRM) is the portion of the TTC that cannot be used for the reservation of firm transmission service because of uncertainties in system operation conditions and the need for operating flexibility to ensure reliable system operation as system conditions change. It is used only for external interfaces under the New England market design. Since VTransco provides transmission service over its non-PTF facilities that are connected only to the internal New England system, VTransco does not reserve TRM for these paths, and the TRM is presently set to zero.

CBM is defined as the amount of firm transmission transfer capability set aside by a TSP for use by the Load Serving Entities. ISO-New England does not set aside any CBM for use by the Load Serving Entities because of the New England approach to capacity planning requirements in the ISO-New England Operating Documents. Load Serving Entities operating within the New England Control Area are required to arrange for their Capacity Requirements prior to the beginning of any given month in accordance with ISO Tariff, Section II.13.7.3.1 (Calculation of Capacity Requirements and Capacity Load Obligation). Load Serving Entities do not utilize CBM to ensure their capacity needs are met; therefore, CBM is not applicable within the New England market design. Accordingly, for purposes of ATC calculation, as long as this market design is in place in New England, the CBM is set to zero (0). VTransco provides local transmission service over its non-PTF facilities that are connected to ISO-NE and the Vermont distribution utilities. VTransco does not reserve CBM for these paths, and the CBM is presently set to zero.
| Path | TTC | ATC | TRM | CBM |
| VTransco- ISO-NE | 9999 | 9999 | 0 | 0 |
Non-firm transmission service under Schedule 21 is always available. Therefore, it is unnecessary to post daily non-firm service that has become available as a result of not scheduled firm transmission service.
TRM and CBM are presently set to zero will be reviewed as appropriate (at a minimum annually) to verify the values.
If a non-PTF path becomes constrained and the yearly or monthly ATC value changes because of a 10 percent or more change in TTC, VTransco will post a narrative for such path.
VTransco performs these calculations for its non-PTF internal interfaces. These calculations are consistent with the ISO calculations for Available Transfer Capability. TRM and CBM for VTransco’s non-PTF posted paths are zero.
ATCF = (TTC-CBM-TRM-ETCF)
ATCNF = (TTC-CBM-TRM- ETCF- ETCNF )
ATCF = (TTC-CBM-TRM-ETCF)
ATCNF = (TTC-CBM-TRM- ETCF- ETCNF + PostbacksNF)
