Attachment 1
Attachment 1-EOP-011-4
Energy Emergency Alerts

Introduction
This Attachment provides the process and descriptions of the levels used by the Reliability
Coordinator in which it communicates the condition of a Balancing Authority which is
experiencing an Energy Emergency.
A.

General Responsibilities
1.

Initiation by Reliability Coordinator. An Energy Emergency Alert (EEA) may be
initiated only by a Reliability Coordinator at 1) the Reliability Coordinator’s own
request, or 2) upon the request of an energy deficient Balancing Authority.

2.

Notification. A Reliability Coordinator who declares an EEA shall notify all Balancing
Authorities and Transmission Operators in its Reliability Coordinator Area. The
Reliability Coordinator shall also notify all neighboring Reliability Coordinators.

B. EEA Levels
Introduction
To ensure that all Reliability Coordinators clearly understand potential and actual Energy
Emergencies in the Interconnection, NERC has established three levels of EEAs. The
Reliability Coordinators will use these terms when communicating Energy Emergencies to
each other. An EEA is an Emergency procedure, not a daily operating practice, and is not
intended as an alternative to compliance with NERC Reliability Standards.
The Reliability Coordinator may declare whatever alert level is necessary, and need not
proceed through the alerts sequentially.
1.

2.

EEA 1 — All available generation resources in use. Circumstances:
•

The Balancing Authority is experiencing conditions where all available
generation resources are committed to meet firm Load, firm transactions, and
reserve commitments, and is concerned about sustaining its required
Contingency Reserves.

•

Non-firm wholesale energy sales (other than those that are recallable to meet
reserve requirements) have been curtailed.

EEA 2 — Load management procedures in effect. Circumstances:
•

The Balancing Authority is no longer able to provide its expected energy
requirements and is an energy deficient Balancing Authority.

•

An energy deficient Balancing Authority has implemented its Operating
Plan(s) to mitigate Emergencies.

16

Attachment 1

•

An energy deficient Balancing Authority is still able to maintain minimum
Contingency Reserve requirements.

During EEA 2, Reliability Coordinators and energy deficient Balancing Authorities have the
following responsibilities:
2.1 Notifying other Balancing Authorities and market participants. The energy deficient
Balancing Authority shall communicate its needs to other Balancing Authorities and
market participants. Upon request from the energy deficient Balancing Authority,
the respective Reliability Coordinator shall post the declaration of the alert level,
along with the name of the energy deficient Balancing Authority on the RCIS website.
2.2 Declaration period. The energy deficient Balancing Authority shall update its
Reliability Coordinator of the situation at a minimum of every hour until the EEA 2 is
terminated. The Reliability Coordinator shall update the energy deficiency
information posted on the RCIS website as changes occur and pass this information
on to the neighboring Reliability Coordinators, Balancing Authorities and
Transmission Operators.
2.3 Sharing information on resource availability. Other Reliability Coordinators of
Balancing Authorities with available resources shall coordinate, as appropriate, with
the Reliability Coordinator that has an energy deficient Balancing Authority.
2.4 Evaluating and mitigating Transmission limitations. The Reliability Coordinator shall
review Transmission outages and work with the Transmission Operator(s) to see if
it’s possible to return to service any Transmission Elements that may relieve the
loading on System Operating Limits (SOLs) or Interconnection Reliability Operating
Limits (IROLs).
2.5 Requesting Balancing Authority actions. Before requesting an EEA 3, the energy
deficient Balancing Authority must make use of all available resources; this includes,
but is not limited to:

3.

2.5.1

All available generation units are on line. All generation capable of
being on line in the time frame of the Emergency is on line.

2.5.2

Demand-Side Management. Activate Demand-Side Management within
provisions of any applicable agreements.

EEA 3 —Firm Load interruption is imminent or in progress. Circumstances:
•

The energy deficient Balancing Authority is unable to meet minimum
Contingency Reserve requirements.

During EEA 3, Reliability Coordinators and Balancing Authorities have the following
responsibilities:
3.1 Continue actions from EEA 2. The Reliability Coordinators and the energy deficient
17

Attachment 1

Balancing Authority shall continue to take all actions initiated during EEA 2.
3.2 Declaration Period. The energy deficient Balancing Authority shall update its
3.3 Reliability Coordinator of the situation at a minimum of every hour until the EEA 3 is
terminated. The Reliability Coordinator shall update the energy deficiency
information posted on the RCIS website as changes occur and pass this information
on to the neighboring Reliability Coordinators, Balancing Authorities, and
Transmission Operators.
3.4 Reevaluating and revising SOLs and IROLs. The Reliability Coordinator shall evaluate
the risks of revising SOLs and IROLs for the possibility of delivery of energy to the
energy deficient Balancing Authority. Reevaluation of SOLs and IROLs shall be
coordinated with other Reliability Coordinators and only with the agreement of the
Transmission Operator whose Transmission Owner (TO) equipment would be
affected. SOLs and IROLs shall only be revised as long as an EEA 3 condition exists, or
as allowed by the Transmission Owner whose equipment is at risk. The following are
minimum requirements that must be met before SOLs or IROLs are revised:
3.4.1

Energy deficient Balancing Authority obligations. The energy deficient
Balancing Authority, upon notification from its Reliability Coordinator of
the situation, will immediately take whatever actions are necessary to
mitigate any undue risk to the Interconnection. These actions may
include Load shedding.

3.5 Returning to pre-Emergency conditions. Whenever energy is made available to an
energy deficient Balancing Authority such that the Systems can be returned to its
pre- Emergency SOLs or IROLs condition, the energy deficient Balancing Authority
shall request the Reliability Coordinator to downgrade the alert level.
3.5.1

Notification of other parties. Upon notification from the energy
deficient Balancing Authority that an alert has been downgraded, the
Reliability Coordinator shall notify the neighboring Reliability
Coordinators (via the RCIS), Balancing Authorities, and Transmission
Operators that its Systems can be returned to its normal limits.
Alert 0 - Termination. When the energy deficient Balancing Authority is
able to meet its Load and Operating Reserve requirements, it shall
request its Reliability Coordinator to terminate the EEA.

3.5.2

Notification. The Reliability Coordinator shall notify all other Reliability
Coordinators via the RCIS of the termination. The Reliability Coordinator
shall also notify the neighboring Balancing Authorities and Transmission
Operators.
