Reliability Standard PRC-005-3 applies to entities registered with NERC as distribution providers (DP), generation owners (GO), and transmission owners (TO). However, the changes to the standard as compared to the one previously approved only affect TOs and GOs.
Reclosing relays are utilized on transmission systems to restore transmission elements to service following automatic circuit breaker tripping. There are several types of reclosing relays, including electromechanical, solid state, and microprocessor-based, which may be applied in a variety of scenarios. Most reclosing relays share three main functions: supervisory, timing, and output. According to NERC, a relay failure is most likely to occur as part of one of these functions. Reclosing relays are typically installed to lessen the burden on transmission operators of manually restoring transmission lines. Relays of this type also provide improved capability in restoration of overhead transmission lines. The degree to which such capability is improved depends on the nature of the fault (permanent or temporary) and on transmission operator practices regarding manual restoration.
While more efficient restoration of transmission lines following temporary faults does provide an inherent reliability benefit, certain applications of reclosing relays can result in undesired relay operation or operation not consistent with relay design, leading to adverse reliability impacts. Because certain applications of reclosing relays can have the potential to impact the Bulk-Power System, it is beneficial to reliability that those relays be included under the applicability of Reliability Standard PRC-005-3.
The change in burden is the result of new provisions related to reclosing relays in the approved PRC-005-3 Reliability Standard. The one-time burden is necessary so that respondents review and update their protection system maintenance programs according to the new standard.
(In addition we are removing the one-time burden of the now completed and superseded PRC-005-2.)
Our estimate regarding the number of respondents is based on an analysis of the generating plants within the footprint of the PJM Interconnection, LLC (PJM) that meet the inclusion criteria of the proposed standard. There are an estimated 23 generating plants in PJM that meet these criteria. These generating plants represent approximately 47,000 MWs of the approximately 184,000 MWs within PJM. Based on 2012 data, total installed capacity in the continental United States is 1,153,000 MWs. Applying the PJM ratio to this total results in 144 plant sites nationwide to which PRC-005-3 would be applicable. We also assume that a substation will be located within 10 miles of each plant site, resulting in an estimated total number of entities that meet the inclusion criteria of 288. Finally, we assume that all GOs and TOs must review their existing plant and substation sites to determine applicability under the proposed standard. We estimate that the burden on GOs and TOs to review their existing plant and substation sites is two hours. We assume that a portion of the two hours are spent by an engineer examining facility data to determine if specific sites meet the applicability of the standard. We assume that the remaining portion of the burden is for a manager to review and sign off on the engineer's analysis.
Entities that do have facilities that meet the applicability of the standard must perform a one-time review of their existing reclosing scheme maintenance program to ensure that it contains at a minimum the activities listed in Table 4 in Reliability Standard PRC-005-3, and that the activities are performed within the applicable maximum interval listed in Table 4. If the existing reclosing scheme maintenance program does not meet the criteria in Reliability Standard PRC-005-3, the entity will have to make certain adjustments to the program. We assume that the work to examine, adjust and get approval for program documentation will require an engineer and a manager a total of eight hours or one whole work day. This estimate is based on Commission staff experience. The record retention requirements are considered usual and customary for this industry.
