Current through Register Vol. 39, No. 6, September 16, 2024
(a) On or
before the last day of each month, every public utility providing North
Carolina retail electric service shall file a Power Plant Performance Report
for the preceding month for review by the Commission, the Public Staff, and any
other interested party.
(b)
Definitions and methodologies used shall be consistent with the latest revision
of North American Electric Reliability Corporation (NERC) Generating
Availability Data Systems (GADS) Data Reporting Instructions.
(1) For purposes of subsection (c) of this
rule, the performance of generating units or power plants that meet both of the
following two conditions (Performance Reporting Plants), shall be reported:
(i) Having a (A) 400 or greater megawatt (MW)
Gross Maximum Capacity (GMC) rating for one unit or (B) 600 or greater MW GMC
rating for the aggregate of multiple generating units of the same type at a
single generation plant, and projected in the most recently filed integrated
resource plan or integrated resource plan update (as applicable) to operate at
35% or greater annual Capacity Factor for the most recent 12-month period
commencing January 1st of the next calendar year.
(ii) For purposes of this subsection
(b)(1)(ii), the determination of the Capacity Factor shall occur on an annual
basis after the filing of the integrated resource plan or integrated resource
plan update (as applicable) and prior to January 1st of the next calendar year.
Once established, the Performance Reporting Plants shall remain unchanged for
the entire calendar year.
(2) For purposes of subsection (d) of this
rule, the outage information shall be provided for each electric generating
unit that is projected in the most recently filed integrated resource plan or
integrated resource plan update (as applicable) to operate at 65% or greater
annual Capacity Factor for the 12-month period commencing January 1st of the
next calendar year (Outage Reporting Plants). For purposes of this subsection
(b)(2), the determination of the Capacity Factor shall occur on an annual basis
after the September 1st filing of the integrated resource plan or integrated
resource plan update (as applicable) and prior to January 1st of the next
calendar year. Once established, the Outage Reporting Plants shall remain
unchanged for the entire calendar year.
(c) The monthly Power Plant Performance
Report shall provide summaries of the generation by each generating unit of all
Performance Reporting Plants, with one summary for the reporting month and
another summary for the 12-month period ending with the reporting month. The
generation summaries for each generating unit of all Performance Reporting
Plants shall include the following:
(1) Gross
Dependable Capacity (GDC) or Net Dependable Capacity (NDC) in megawatts
(MW);
(2) Hours in
period;
(3) Total net megawatt
hours (MWh) possible in period;
(4)
Net MWh generated during period;
(5) Capacity factor (as a % of GDC or
NDC);
(6) Equivalent availability
(net MWh generation possible in period, less net MWh generation not available
in period) divided by net MWh generation possible in period); and
(7) Heat rate (in BTU per net kWh).
(d) The monthly Power Plant
Performance Report shall list each outage during the period for each generating
unit of the Outage Reporting Plants. The outage information shall include the
following:
(1) Generating unit affected by
outage;
(2) Date(s) of each
outage;
(3) Duration of each
outage;
(4) Cause of each
outage;
(5) Explanation for cause
of outage, if known;
(6) Remedial
action to prevent recurrence of outage, if any; and
(7) Whether the outage is forced or
scheduled, and if scheduled, the classification of the outage.
