Introduction
NPCC has established a Reliability Assessment Program to bring together the
work done by the Council, its member systems and Areas relevant to the
assessment of bulk power system reliability. As part of the Reliability
Assessment Program, NPCC reviews studies, assessments, or other documentation
associated with new generation, transmission, and electricity end-user facilities (i.e.
“new facilities”) intending to connect to the interconnected transmission system
within the region, to ensure that such new facilities, and the resulting bulk power
system, are in conformance with all applicable NPCC criteria, guides and
procedures (i.e. NPCC’s “facility connection requirements”).
The purpose of this guide is to summarize NPCC’s criteria, guides and procedures
as they pertain regarding new facilities, and to describe NPCC’s review process to
ensure conformance with these requirements. It will also describe NPCC’s role in
assuring compliance with the Section I.C. (Facility Connection Requirements) of
the NERC Planning Standards.
2.0
NPCC’s Role Regarding NERC Facility Connection Requirements
The Introduction to Section I.C. of the NERC Planning Standards states that,
“All facilities involved in the generation, transmission, and use of
electricity must be properly connected to the interconnected transmission
systems to avoid degrading the reliability of the electric systems to which
they are connected. To avoid adverse impacts on reliability, generation
and transmission owners and electricity end-users must meet facility
connection and performance requirements as specified by those
responsible for the reliability of the interconnected transmission systems.”
Further, Section I.C. contains the following Standards and Measurements
pertaining to facility connection Requirements:
Standards
S1.
Facility connection requirements shall be documented,
maintained, and published by voltage class, capacity, and
other characteristics that are applicable to generation,
transmission, and electricity end-user facilities and which are
connected to, or being planned to be connected to, the
interconnected transmission systems.

S2.
Generation, transmission, and electricity end-user facilities,
and their modifications, shall be planned and integrated into
the interconnected transmission systems in compliance with
NERC Planning Standards, applicable Regional, subregional,
power pool, and individual system planning criteria, guides,
and facility connection requirements.
Measurements
M1.
Those entities responsible for the reliability of the interconnected
transmission systems shall document, maintain, and publish facility
connection requirements for generation facilities, transmission facilities,
and electricity end-user facilities to ensure compliance with NERC
Planning Standards and applicable Regional, subregional, power pool,
and individual system planning criteria, guides, and facility connection
requirements. The documentation shall include the assumptions and
considerations used to establish the requirements, and shall be provided to
the Regions and NERC on request. (S1)
M2.
Those entities responsible for the reliability of the interconnected
transmission systems and those entities seeking to integrate generation
facilities, transmission facilities, and electricity end-user facilities shall
coordinate and cooperate on their respective assessments to evaluate the
reliability impact of the new facilities and their connections on the
interconnected transmission systems and to ensure compliance with NERC
Planning Standards and applicable Regional, subregional, power pool,
and individual system planning criteria, guides, and facility connection
requirements. The results of these assessments shall be documented and
provided to the Regions and NERC on request. (S2)
Within NPCC, the Council, its Areas and member systems share responsibility for
the reliability of the interconnected transmission systems in a hierarchical manner,
and, therefore, share responsibility for compliance with the above NERC standards
and measurements in accordance with their respective roles. The role of NPCC is
to establish appropriate facility connection requirements from the Regional
perspective, to monitor the conformance of the Areas and member systems with
those requirements, and to coordinate its review of the reliability impact of new
facilities with other entities’ assessments as appropriate. In monitoring the
conformance of the Areas and member systems, NPCC does not duplicate the
studies and assessments conducted by the Areas and member systems. Rather,
through the work of the Reliability Coordinating Committee and its task forces,
NPCC reviews the documentation of applicable studies and assessments completed
by the Areas and member systems.

NPCC may also request documentation from the Areas and member systems
regarding their facility connection requirements for the purpose of ensuring
compatibility with NPCC’s requirements.
3.0
NPCC Facility Connection Requirements
NPCC’s “facility connection requirements” are embedded within several of its
criteria, guides, and procedures. The NPCC documents that pertain most directly
to facility connection requirements are as follows:
A-2
Basic Criteria for Design and Operation of Interconnected Power
Systems, August 9, 1995

concerning Resource Adequacy and Transmission Capability.
Lead Task Force: Task Force on Coordination of Planning

Description: Objectives, principles and requirements are presented to
assist the NPCC Areas in formulating plans and procedures to be followed
in an emergency or during conditions which could lead to an emergency.
Lead Task Force: Task Force on Coordination of Operation
A-5
Bulk Power System Protection Criteria, August 9, 1995
Description: This document establishes the minimum design objectives
and recommends design practices to minimize the severity and extent of
system disturbances and to minimize possible damage to system equipment.

iC-29 Procedures for System Modeling: Data Requirements and Facility
Ratings, New Interim Document
Description: Procedure for collection of data needed to simulate and
analyze the performance of the bulk power system.
Lead Task Force:
Task Force on System Studies
The above requirements fall into the general categories of design requirements,
data requirements, and review requirements. The design requirements are intended
to ensure that the planned bulk power system, including planned new facilities,
meet minimum reliability standards. The system design requirements include
considerations for system design, operation, and protection. When connecting
new facilities to the bulk power system, generation owners, transmission providers
and end-user entities must coordinate various design and operational aspects of the
facilities, including equipment ratings and the availability and use of reactive power
capability.
The data requirements are necessary to ensure that NPCC, including its Areas and
member systems, and other Regions can analyze the reliability of their respective
systems.
The review requirements are necessary to ensure that the design requirements are
met. This will be discussed further in Section 4.0.

Process for Monitoring Conformance
The member systems are primarily responsible for ensuring that their facilities, and
those of non-member entities that connect to their system, are in conformance with
the NPCC criteria and guides. The member systems present documentation of
such conformance for review by the appropriate task force(s) in accordance with
the NPCC guides and procedures. The task force reports the results of their
review to the Reliability Coordinating Committee (RCC).
The Areas review the reliability of the planned bulk power system within their
respective Areas in accordance with the Guidelines for NPCC Area Transmission
Reviews (B-4). These reviews consider the collective impact of all new facilities
planned through the review period.
Again, the task forces review the
documentation provided in these Area reviews in accordance with the guideline,
and report the results of their review to the RCC.
Member systems or Areas may conduct ad hoc assessments of the impact of new
facilities on the reliability of the bulk power system with the results of such
assessments presented to NPCC as appropriate.
The Task Force on System Studies monitors the status of new facilities proposed
or planned to connect to the system, including the status of consideration of those
facilities in Area transmission reviews, through regular review and update of the
NPCC Major Project List.
