Guidelines and Technical Basis
Many aspects of managing Interchange are supported by software applications. There are
fundamental tasks that each entity should be able to perform in an electronic manner as listed
below.
A Load-Serving Entity and Balancing Authority that submits Requests for Interchange should
have the capability to electronically:
•
Submit a Request for Interchange to a Sink Balancing Authority
•
Submit a request to modify Interchange
•
Receive distributions of Confirmed Interchange
•
Receive distributions of Reliability Adjustment Arranged Interchanges
Each Sink Balancing Authority should have the capability to electronically:
•
Receive a Request for Interchange
•
Receive a request to modify Interchange
•
Validate Requests for Interchange by verifying:
•
o
Source Balancing Authority megawatts equal Sink Balancing Authority megawatts
(adjusted for losses, if appropriate).
o
All reliability entities involved in the Arranged Interchange are valid.
o
Generation source and Load sink are defined.
o
Megawatt profile is defined.
o
Interchange duration is defined.
Validate request to modify Interchange by verifying:
o
Source Balancing Authority megawatts equal Sink Balancing Authority megawatts
(adjusted for losses, if appropriate).
o
Megawatt profile is defined.
o
Interchange duration is defined.
•
Distribute the validated Request for Interchange as Arranged Interchange
•
Distribute the validated Reliability Adjustment Arranged Interchanges
•
Receive communication of approval or denial of Arranged Interchange
o
Distribute notification as each entity approves or denies an Arranged Interchange.
o
Transition Arranged Interchange to Confirmed Interchange if all approvals are
received.
o
Distribute notification of whether Arranged Interchange was transitioned to
Confirmed Interchange or not.

INT-006-5 Supplemental Material
o
•
•
Submit a request to modify Interchange
Each Load-Serving Entity that approves or denies Arranged Interchange, and each
Balancing Authority and Transmission Service Provider should have the capability to
electronically:
o
Receive distribution of Arranged Interchange
o
Communicate approval or denial of the Arranged Interchange to the Sink Balancing
Authority
o
Receive notification of whether Arranged Interchange was transitioned to Confirmed
interchange or not.
o
Submit a request to modify Interchange
While Interchange is normally facilitated using electronic communication and software
tools, there are occasions with those electronic capabilities are reduced or unavailable. It
is recommended that all entities involved in aspects of Interchange should have, maintain
and implement a plan describing the manner and timing in which all capabilities listed
above will be provided when electronic capabilities are reduced or unavailable. Each plan
should address the following topics:
o
Alternate methods of communicating Interchange information between Purchasing
Selling Entities, Balancing Authorities, and Transmission Service Providers.
o
How to notify others that it is activating the plan
o
How it will process requests for emergency Arranged Interchange and Reliability
Adjustment Arranged Interchange.
o
Restrictions and limitations that may apply during the period of reduced or
unavailable capability (such as limits on volume, only accepting emergency
transactions, etc.).
o
Delegation of approval rights and proxy actions, if such approaches will be used.
o
How known Confirmed Interchange will be scheduled following a reduction in or loss
of capability.
o
Personnel plans for short-term and extended periods.
o
Training of personnel in the use of the plan.
Rationale:
During development of this standard, text boxes were embedded within the standard to explain
the rationale for various parts of the standard. Upon BOT approval, the text from the rationale
text boxes was moved to this section.
Rationale for R1:
Balancing Authorities must take action on a received Arranged Interchange within a certain
time frame. Requirement R1, Parts 1.1 and 1.2 provide reliability-related reasons that a
Balancing Authority must deny an Arranged Interchange, but Balancing Authorities may deny
Page 14 of 15
INT-006-5 Supplemental Material
for other reasons. If the conditions described in Requirement R1, Parts 1.1 or 1.2 are recognized
after approval is granted, the Balancing Authority may curtail the Confirmed Interchange prior
to implementation.
Rationale for R2:
TSPs must take action on a received Arranged Interchange within a certain time frame.
Requirement R2, Part 2.1 provides reliability-related reasons that a TSP must deny an Arranged
Interchange, but TSPs may deny for other reasons. If the conditions described in Requirement
R1, Part 2.1 are recognized after approval is granted, the TSP may curtail the Confirmed
Interchange prior to implementation.
