Current through Register Vol. 54, No. 38, September 21, 2024
(a) An electric
public utility subject to the jurisdiction of the Commission shall include in
its electric tariff rules and regulations filed with the Commission the
following provision:
(1) RULE
EMERGENCY LOAD CONTROL.
(i) A load emergency situation exists
whenever:
(A) The demands for power on all or
part of the utility's system exceed or threaten to exceed the capacity then
actually and lawfully available to supply the demands.
(B) System instability or cascading outages
could result from actual or expected transmission overloads or other
contingencies.
(C) The conditions
exist in the system or another public utility or power pool with which the
utility's system is interconnected and cause a reduction in the capacity
available to the utility from that source or threaten the integrity of the
utility's system.
(ii) In
this case, the utility shall take the reasonable steps as the time available
permits to bring the demands within the then-available capacity or to otherwise
control load. The steps shall include, but are not limited to, reduction or
interruption of service to one or more customers, in accordance with the
utility's procedures for controlling load.
(2) RULE
EMERGENCY ENERGY CONSERVATION. An emergency energy
conservation situation exists whenever events result or, in the judgment of the
utility, threaten to result in a restriction of the fuel supplies available to
the utility or its energy vendors, so that the amount of electric energy which
the utility is able to supply is or will be adversely affected. In the event of
an emergency energy conservation situation, the utility shall take reasonable
measures that it believes necessary and proper to conserve available fuel
supplies. The measures may include, but are not limited to, reduction,
interruption or suspension of service to one or more of its customers or
classes of customers in accordance with the utility's procedure for emergency
energy conservation.
(b) A utility shall establish procedures for
controlling load and emergency conservation.
(1) These procedures shall include schedules
of load shedding priorities to be followed in compliance with subsection
(a).
(2) These procedures may be
revised by the utility, and shall be revised if required by the
Commission.
(3) A copy of the
procedures or of the revision currently in effect shall be kept available for
public inspection at the office at which the utility maintains a copy of its
tariff for public inspection, and another copy shall be kept on file with the
Commission's Bureau of Conservation, Economics and Energy Planning.
(c) In the event of either a load
emergency situation or an emergency energy conservation situation, as defined
under subsection (a), the following emergency notification procedures apply:
(1) During load emergencies, initial notice
shall be provided by telephone to the Commission no later than the time a
voltage reduction warning is issued on the electric system. If a utility does
not have the capability to implement system-wide automatic voltage reductions,
notice shall be provided to the Commission prior to the implementation of
emergency measures which would have a direct impact on firm customers.
Notification shall be provided to the Commission as each subsequent load
control procedure is either implemented or cancelled. During the course of the
load emergency situation, the affected utility shall provide other emergency
related information to the Commission that the Commission determines to be
necessary. Information shall be provided by fax at a minimum of every 3 hours
commencing with initial notification of an emergency situation and shall
include the following:
(i) System operating
capacity.
(ii) Current system
load.
(iii) Projected system peak
load and hour.
(iv) System
operating reserve capacity.
(v)
Capacity transactions.
(vi)
Unavailable generating units.
(vii)
Status of implementation of emergency operating procedures.
(viii) Customers and loads affected by manual
load shedding, if applicable.
(2) During energy conservation emergencies,
notice shall be provided by telephone to the Commission at the time of initial
implementation of measures which the utility determines to be necessary to
conserve available fuel supplies and which would have a direct impact on firm
customers. Notification shall be provided to the Commission as each subsequent
emergency conservation procedure is either implemented or cancelled. During the
course of the emergency energy conservation situation, the affected utility
shall provide other emergency related information to the Commission that the
Commission determines to be necessary. Information shall be provided by fax at
a minimum of every 3 hours commencing with initial notification of an emergency
situation and shall include the following:
(i)
Fuel inventories.
(ii) Fuel
deliveries.
(iii) Burn
rates.
(iv) Curtailment schedules,
if applicable.
(3) The
utility shall designate emergency contact individuals from which emergency
information may be obtained and provide the Commission with a current list of
contacts.
(4) Utilities which
operate within a power pool or similarly integrated bulk power system with a
single system operator shall provide notification and other emergency related
information to the Commission through their designated representative if the
emergency situation affects the entire integrated system, in lieu of individual
utility notification.
(5) Section
67.1 (relating to general
provisions) does not apply to either load emergency situations or emergency
energy conservation situations.
(6)
The Commission will provide information to the Pennsylvania Emergency
Management Agency during emergency situations.
(7) The Commission will designate emergency
contact individuals to be contacted by the utilities to meet the requirements
of this section. The Commission will provide the current list of Commission
contacts to the utilities and the Pennsylvania Emergency Management
Agency.
