Summary of New or Amended Reliability Standards and Criteria for which OEB Review Period is Closed 

The IESO is responsible for communicating to market participants new or amended reliability standards and criteria which may be subject to the Ontario Energy Board's (OEB) review. The OEB or any person may make an application for review of a reliability standard as long as actions are initiated within the time prescribed in sections 36.1 and 36.2 of the Electricity Act, 1998:

  • IESO posts a new or amended reliability standard on its website within seven days of it being notified by the standards authority.
  • There is a 21-day window for any market participant, including the IESO, to apply to the OEB for review of the reliability standard. The OEB is also able to initiate its own review within 120 days.
  • If there is no review, the standard would go into effect under the Market Rules upon the enforcement date of the reliability standard.
  • If reviewed, the OEB has the authority to stop the standard from applying in Ontario and to refer it back to the standards authority.

The table below provides a summary of  new or amended reliability standards and criteria for which the OEB review process was closed in 2009.

Approval of the following five (5) standards and twenty (20) definitions:
MOD-001-1 - Available Transmission System Capability
MOD-008-1 -Transmission Reliability Margin Calculation Methodology
MOD-028-1 - Area Interchange Methodology
MOD-029-1 - Rated System Path Methodology
MOD-030-2 - Flowgate Methodology

Interpretation4 of:
MOD-001-1 - Available Transmission System Capability, Requirements R2 and R8, and
MOD-029-1 - Rated System Path Methodology, Requirements R5 and R6

The proposed reliability standards and associated definitions significantly increase the rigor and structure of ATC calculations and related methodologies. They will promote Open Access Transmission Tariff reform through increased transparency, standardization, and consistency in ATC calculations.









The interpretation clarifies the applicability of the requirements of MOD-001-1 to "advisory ATC" used by NYISO and whether or not requirements R5 and R6 of MOD-029-1 could be met by certain outputs of NYISO's unit commitment and dispatch software.

This interpretation clarifies the meaning of the word "port" as used in Requirement R2.



The standard was modified to correct errors in the WECC Regional Differences section.



These revisions remove three waivers that were applicable to the Midwest Independent System Operator (MISO)





This interpretation clarifies the scope of R1 and specifically if it requires maintenance and testing programs for battery chargers, auxiliary relays and sensing devices, transmission line re-closing relays and DC circuitry. It also provides examples of associated communications systems as referred to in R1.

The interpretation clarifies when a special protection system should be regarded as "degraded" so that entities may inform their Reliability Coordinator.






The interpretation clarifies what is required for system simulations performed to meet the intent of R1.3.10, which is to "include the effects of existing and planned protection systems, including any backup or redundant systems".

Revisions to the following NERC standards:

PER-005-1- System Personnel Training

PER-004-2- Reliability Coordination - Staffing

PER-005-1 is a new standard that wholly supersedes approved Reliability Standard PER-002-0 and certain requirements in PER-004-1. It requires the use of a systematic approach to training in developing System Operator training programs, requires verification that System Operators can perform their assigned tasks, and sets minimum annual requirements for operator training. PER-004-1 was modified to remove the requirements now covered by PER-005-1

Errata for the following three NERC standards:
RO-006-4.1 - Reliability Coordination- Transmission Loading Relief (TLR)
MOD-021-0.1 - Documentation of the Accounting Methodology for the Effects of Controllable Demand-Side Management in Demand and Energy Forecasts
PER-001-0.1 - Operating Personnel Responsibility and Authority


NUC-001-2 - Nuclear Plant Interface Coordination

As defined in NERC Standards Committee procedures, errata are errors in approved standards that, if corrected, do not change the scope or intent of the associated approved standard and do not have a material impact on the end users of the standard. In the present case, these errors are discrepancies identified after the standards were initially submitted.







Existing standard, NUC-001-1, was revised in response to the FERC's directive in Order No. 716 issued on October 16, 2008. In Order No. 716, FERC expressed concern that Requirement R9.3.5 of NUC-001-1 was ambiguous in describing nuclear plant coping times for station blackouts and restoration of off-site power, and directed NERC to modify the requirement to clarify references to coping times and off-site power restoration. The revised standard meets this directive. NUC-001-1 will be retired upon the effective date of NUC-001-2.

Violation Risk Factors (VRFs) and Violation Severity Levels (VSLs) for each reliability standard approved by the NERC Board of Trustees.

Violation Risk Factors define the potential reliability significance of each requirement, which may be designated as a High, Medium, or Lower Risk. Violation Severity Levels define the degree to which compliance with a Reliability Standard requirement was not achieved and may be classified as Lower, Moderate, High and Severe.

Note:
  1. Last Date to Request an OEB Review is 21 days after the IESO posts the approved standards or criteria from NERC or NPCC to this website. Please note that the OEB has 120 days for its review period from the posted date.
  2. The mandatory enforcement dates of NERC reliability standards and NPCC criteria are governed by Chapter 5, sections 1.2.6 and 1.2.7 of the Market Rules.
  3. Applicability includes the IESO and Ontario Entities including T - Transmitters, G - Generators, W - Connected Wholesale Customers, PSE - Purchasing-Selling Entities, D - Distributors, and the OPA (Ontario Power Authority)
  4. An interpretation is offered by a designated Standard Drafting Team (SDT) in response to an industry request. It provides clarification of the intent of a requirement but may not expand or redefine it. If approved by the industry ballot pool and the NERC Board of Trustees (BOT), these interpretations are appended to the standard and filed with the OEB. When the affected Reliability Standard is next revised using the Reliability Standards Development Process, the interpretation will then be incorporated into the Reliability Standard.
