Subject: FAC 12, FAC 13

Marcie and Ed - here is the mapping of the two standards to the new standards:

Here is FAC 12:


The Reliability Coordinator and Planning Authority shall each document its current

methodology used for developing its inter-regional and intra-regional Transfer Capabilities

(Transfer Capability Methodology). The Transfer Capability Methodology shall include all of

the following:

R1.1. A statement that Transfer Capabilities shall respect all applicable System Operating

Limits (SOLs).

R1.2. A definition stating whether the methodology is applicable to the planning horizon or

the operating horizon.

R1.3. A description of how each of the following is addressed, including any reliability

margins applied to reflect uncertainty with projected BES conditions:

R1.3.1. Transmission system topology

R1.3.2. System demand

R1.3.3. Generation dispatch

R1.3.4. Current and projected transmission uses



ALL OF R1 IS EITHER IN THE METHODOLOGY ITSELF OR REQUIRED TO BE IN THE ATCID.  NOTE WE ASSIGN THIS TO THE TRANSMISSION OPERATOR BASED ON 1.) OUR UNDERSTANDING OF THE FUNCTIONAL MODEL, AND 2.) THE SCOPE OF THE METHODOLOGY CHOSEN IS USUALLY TARIFF BASED, NOT REGION BASED.  





R2. The Reliability Coordinator shall issue its Transfer Capability Methodology, and any changes

to that methodology, prior to the effectiveness of such changes, to all of the following:

R2.1. Each Adjacent Reliability Coordinator and each Reliability Coordinator that indicated

a reliability-related need for the methodology.

R2.2. Each Planning Authority and Transmission Planner that models any portion of the

Reliability Coordinator’s Reliability Coordinator Area.

R2.3. Each Transmission Operator that operates in the Reliability Coordinator Area.

R3. The Planning Authority shall issue its Transfer Capability Methodology, and any changes to

that methodology, prior to the effectiveness of such changes, to all of the following:

R3.1. Each Transmission Planner that works in the Planning Authority’s Planning Authority

Area.

R3.2. Each Adjacent Planning Authority and each Planning Authority that indicated a

reliability-related need for the methodology.

R3.3. Each Reliability Coordinator and Transmission Operator that operates any portion of

the Planning Authority’s Planning Authority Area.



R2 AND R3 ARE ADDRESSED BY MOD-001 R4 AND R5



R4. If a recipient of the Transfer Capability Methodology provides documented technical

comments on the methodology, the Reliability Coordinator or Planning Authority shall provide

a documented response to that recipient within 45 calendar days of receipt of those comments.

The response shall indicate whether a change will be made to the Transfer Capability

Methodology and, if no change will be made to that Transfer Capability Methodology, the

reason why.

NAESB IS HANDLING THIS.



And here is FAC-013

R1. The Reliability Coordinator and Planning Authority shall each establish a set of inter-regional

and intra-regional Transfer Capabilities that is consistent with its current Transfer Capability

Methodology.



THIS IS COVERED BY THE INDIVIDUAL METHODOLOGY STANDARDS THEMSELVES (SEE MOD-028 R7; MOD-029 R4; AND MOD-030 R2.6)



R2. The Reliability Coordinator and Planning Authority shall each provide its inter-regional and

intra-regional Transfer Capabilities to those entities that have a reliability-related need for such

Transfer Capabilities and make a written request that includes a schedule for delivery of such

Transfer Capabilities as follows:

R2.1. The Reliability Coordinator shall provide its Transfer Capabilities to its associated

Regional Reliability Organization(s), to its adjacent Reliability Coordinators, and to

the Transmission Operators, Transmission Service Providers and Planning Authorities

that work in its Reliability Coordinator Area.

R2.2. The Planning Authority shall provide its Transfer Capabilities to its associated

Reliability Coordinator(s) and Regional Reliability Organization(s), and to the

Transmission Planners and Transmission Service Provider(s) that work in its Planning

Authority Area.



THESE ARE COVERED BY MOD-001 R9 (DATA EXCHANGE)
