APPENDIX B
CERTIFICATION PROCESS FOR METERING FACILITIES
Paragraphs B1 to B3 of this Appendix describe the steps that ISO
Authorized Inspectors and the ISO will take to certify Metering Facilities of
ISO Metered Entities.
The steps described here will also be applicable to SC Metered Entities
where no certification requirements are imposed on a SC Metered Entity
by its Local Regulatory Authority.
Paragraph B5 of this Appendix describes the manner in which requests
must be made to the ISO to perform the certification of Metering Facilities.
B1
Documentation to be Provided by ISO/SC Metered Entity
The ISO Metered Entity or SC Metered Entity shall provide the ISO and
the ISO Authorized Inspector with schematic drawings (both detailed and
one line) of the Metering Facilities being considered for ISO certification.
Such drawings shall be dated, bear the current drawing revision number
and show all wiring, connections and devices in the circuits. Drawings
shall also be provided for instrument transformers to the meter and the
meter to the WEnet POP.
In addition, the ISO Metered Entity or SC Metered Entity will provide the
ISO and the ISO Authorized Inspector with a completed ISO Meter
Certification Form (a copy of which forms part of this Appendix) in respect
of each set of Metering Facilities being considered for ISO certification.
B2
Documentation to be completed by the ISO Authorized Inspector
The ISO Authorized Inspector will complete an ISO approved site
verification form (an internal ISO document) in relation to each set of
Metering Facilities that it inspects. The site verification form and the ISO
Meter Certification Form will be the official forms used to document
whether Metering Facilities meet the ISO certification criteria.
If there are any discrepancies between the ISO certified drawings on file
and the actual metering circuitry inspected by the ISO Authorized
Inspector or the ISO, then the ISO Authorized Inspector or the ISO will
document that discrepancy and revise the schematic drawings provided to
the ISO. The ISO Authorized Inspector will notify the ISO of the
discrepancy and give the ISO Metered Entity or SC Metered Entity a
notice detailing the discrepancies within 24 hours of that notification.
