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and superseded PRC-005-2.)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.
