    The MRO Subject Matter Expert Team is an industry stakeholder group which includes subject matter experts from MRO member organizations in various technical areas. Any materials, guidance, and views from stakeholder groups are meant to be helpful to industry participants; but should not be considered approved or endorsed by MRO staff or its board of directors unless specified.

    Disclaimer

    The Midwest Reliability Organization (MRO) Standards Committee (SC) is committed to providing training and non-binding guidance to industry stakeholders regarding existing and emerging Reliability Standards. Any materials, including presentations, were developed through the MRO SC by Subject Matter Experts (SMEs) from member organizations within the MRO region.

    In 2014, SMEs in the field of System Operator Communications were brought together to prepare a guide for complying with NERC Reliability Standard TPL-001-4 (Transmission System Planning Performance Requirements).

    The materials have been reviewed by MRO staff and provide reasonable application guidance for the standard(s) addressed. Ultimately, demonstrating compliance depends on a number of factors including the precise language of the standard, the specific facts and circumstances, and quality of evidence.

    INTRODUCTION

    NERC Reliability Standard TPL-001-4 Transmission System Planning Performance Requirements (TPL-001-4) replaced the previous suite of Transmission Planning Reliability Standards - TPL- 001-0.1, TPL-002-0b, TPL-003-0a, and TPL-004-0a. The new standard, TPL-001-4, is applicable to Transmission Planners (TP) and Planning Coordinators (PC).

    There were many modifications in TPL-001-4, compared to the predecessor TPL Standards. A few notable modifications are:1

    • A system model maintenance requirement (R1) • Short circuit analysis and corrective action requirements (R2.3 & R2.8) • Spare equipment strategy requirements (R2.1.5) • Inclusion of dynamic load modeling (R2.4.1) • Higher system performance for extra high voltage contingency events, such as extra high

    voltage ( EHV) bus faults, internal breaker faults, N-1-1 Contingency events that involve a generator (Table 1)

    • Limitations on the amount of non-Consequential Load Loss following planning events (Table 1)

    • Addition of shunt device Contingency events (Table 1, P1-4, P3-4, P4-4, P5-4, P6-3) • Opening of a line section without a fault (P2.1) • Differentiation between Bus-tie and non-Bus-tie breakers (Table 1 P2 & P4) • Addition of generation plus another Element Contingency events (Table 1, P3) • Obligation to consider both stuck breaker and system protection relay failure events (Table

    1 P4 & P5) • Additional extreme event contingency events, such as loss of two Elements without system

    adjustment (N-2), loss of two generating plants (Table 1, Extreme Events) • Removed a few extreme event contingency events (such as non-redundant Special

    Protection System (SPS)/Remedial Action Scheme (RAS) Misoperation [former TPL-004- 0 D12 & D13] and power swing oscillations due to event in another Regional Entity area [former TPL-004-0 D14])

    OVERVIEW

    Purpose: Establish Transmission system planning performance requirements within the planning horizon to develop a Bulk Electric System (BES) that will operate reliably over a broad spectrum of System conditions and following a wide range of probable Contingencies.
