MISO Market Capacity Emergency
Procedure
RTO-EOP-002-r17
effective date: JUN 01, 2014
1 Purpose
MISO is responsible for determining, declaring, and communicating when a
capacity or energy Emergency is forecasted, occurring, or has ended in the MISO
Balancing Authority Area (MBAA). MISO shall provide instructions to Local
Balancing Authorities (LBAs), Transmission Operators (TOPs), Generation
Operators (GOPs), and Market Participants (MPs) to manage capacity or energy
Emergencies.
Transmission System Emergencies that require immediate action will be declared
and resolved through actions identified in MISO RTO-EOP-004 Transmission
Emergencies Procedure. However, transmission constraints which result in
limitations in transferring energy into the MBAA or a sizeable sub-area of the MBAA
and result in a capacity or energy Emergency for such area will be managed
through this procedure.
This procedure serves as MISO’s capacity and energy Emergency plan for its
Balancing Authority (BA) and provides specific alert, warning, and event levels to
mitigate capacity and/or energy Emergencies. As conditions require, MISO may
provide instructions to move to any level or step in this procedure while providing
instructions to complete actions described in earlier levels or steps as time permits.
Expected implementation time to complete each level or step may vary depending
on the time of day and system conditions, which will be considered when deciding
to move to different levels or steps described in this procedure.
Implementation of this procedure may necessitate warnings, instructions or
directives for the entire MISO Reliability Footprint, MBAA or a sub-area of the
MBAA. A sub-area may consist of a single LBA Area, a group of LBA Areas, or
portions of an LBA Area(s) (for portions of an LBA area, a 1000 MW minimum
threshold will generally be used).
MISO, with regard to all of its responsibilities, shall render all available emergency
assistance to others as requested, provided that the requesting entity has
implemented its comparable emergency procedures, unless such actions would
violate safety, equipment, regulatory or statutory requirements. b
The MISO Reliability Coordinator and Balancing Authority Operator have the
responsibility and clear decision-making authority to take whatever actions needed to
ensure the reliability of its area and shall exercise specific authority to alleviate capacity
and energy Emergencies. c During normal and emergency conditions, operating
personnel have the authority to take or direct timely and appropriate real-time actions.
Such actions include shedding of firm load to prevent or alleviate System Operating
Limit (SOL) or Interconnection Reliability Operating Limit (IROL) violations. These
actions are performed without obtaining approval from higher-level personnel. d

Capacity Shortages m
3.1.1 MISO monitors capacity and energy adequacy conditions and commits
resources Day-Ahead and during the Operating Day to ensure forecasted
load is satisfied for the entire MBAA. n Additionally, the commitment process
recognizes transmission constraints and honors zonal operating reserve
requirements. Zonal operating reserve requirements are used by the MBAA
to meet load forecasting errors, load diversity, and operating contingencies
including Regional Reserve Sharing Agreement obligations for MISO within
each of its operating zones.
3.1.2 During an Energy Emergency Alert (EEA)-Level 3 Event, load reductions will
be administered pro-rata across the entire energy deficient area.
3.1.2.1 Pro-rata Load Shedding reliability directives will be issued, via the MCS
Firm Load Shed Tool or verbally as a backup, to LBAs within an event
area based on the ratio of the LBA’s forecasted or actual load to the total
forecasted or actual load of the event area, taking into account applicable
transmission security requirements. Analysis will be performed when
defining the event area to minimize the likelihood that actions directed to

relieve the energy Emergency will result in system operating limits being
exceeded.
3.1.3 Operating Reserve requirements for MISO’s BA are in accordance with
regional requirements. Please refer to the following for further information:

ReliabilityFirst (RF) – BAL-002-RFC-02

Midwest Reliability Organization – MBAL-002-0

SERC Reliability Corporation

SPP Regional Entity
3.1.4 The intent of the alerts, warnings, and event notifications is to keep all
affected system personnel aware of the forecast and/or actual status of the
MBAA. Notifications and summaries are communicated via MISO’s
Communication System (MCS), the www.misoenergy.org web site, and the
North American Electric Corporation (NERC) Reliability Coordinator
Information System (RCIS) to assure that all Members, LBAs, TOPs, and
neighbors receive the appropriate information. MISO will also post to MISO’s
Open Access Same-Time Information System (OASIS) a notice of the
existence and duration of the conditions requiring the implementation of this
procedure. More detailed information is communicated to LBAs and TOPs
as appropriate. Refer to Section 3.7 of this procedure on MISO
Communication Protocols. o
3.1.5 When the MISO BA declares an Energy Emergency, MISO’s RC will declare
an NERC EEA in accordance with the NERC EEA Levels and RTO-AOP-013
NERC Operating Conditions Procedure. MISO’s Reliability Coordinator (RC)
will also take appropriate steps in accordance with MISO’s Tariff to mitigate
the energy Emergency condition, including a request for emergency
assistance if needed. Should sufficient relief be obtained during the
implementation of one of the actions during an event step, subsequent
actions within that event step need not be taken. p q
Note: MISO will only use the assistance provided by the
interconnection’s frequency bias for the time needed to implement
corrective actions. r
Note: MISO shall not unilaterally adjust generation in an attempt to
return Interconnection frequency beyond that supplied through
frequency bias action and interchange schedule changes. s
3.1.6 MPs with registered Load Modifying Resources (LMRs) will be notified, time
permitting, to ensure LMR availability data in the MCS-LMR Tool is updated
and accurate as much as possible during Capacity Emergencies or other
applicable system conditions. In the event that LMR implementation is
ADM-01
Page 3 of 42
Public
MISO Market Capacity Emergency
Procedure
RTO-EOP-002-r17
effective date: JUN 01, 2014
required where there is no time for this notification, MISO will communicate
via the MCS-LMR Tool implementation instructions using the then current
availability information in the Tool, assuming it to be correct.
3.1.7 MPs and LBAs will be notified, time permitting, to ensure that Voluntary Load
Management (VLM) information is up to date in the MCS Tool during
Capacity Emergencies or other applicable system conditions.
3.1.8 MISO may call for a Max Gen Alert, Warning or Event, and/or EEA level prior
to the actual forecasted start time of such Alert, Warning, Event or EEA level.
The purpose of this would be to communicate forecasted conditions that
meet the criteria of these levels as well as to provide notice of certain
implementation steps which require longer notifications times. An example
would be an LMR which has an 8 hour notification time, requiring
implementation instructions to be sent prior to the actual start time of the
Event or EEA. Due to the dynamic nature of the Bulk Electric System (BES)
these preliminary declarations and instructions may be cancelled prior to the
actual start time of the forecasted Alert, Warning, Event or EEA as conditions
warrant. In the circumstance where the preliminary declaration is not
cancelled, MISO will attempt to complete all other preliminary steps in this
procedure prior to the start of the earlier declared step implementation.
3.1.9 Elevating an Interchange Transaction from Priority 6 to Priority 7 per NERC
EOP-002:
MISO is operating as a single BA, performing a centralized security
constrained economic dispatch to serve its entire load. An individual Load
Serving Entity (LSE) would not request the use of Capacity Benefit Margin
(CBM) since there will not be a single LSE considered deficient during
capacity emergencies. Given this fact, MISO Members in the MBAA who are
registered as LSE’s would not have a basis for requesting MISO to initiate a
NERC EEA as required of the deficient LSE’s in NERC EOP-002 R9.1
Capacity and Energy Emergencies procedure. t
MISO’s RC will use NERC EEA-Level 1 to forecast the change of the priority
of transmission service of an Interchange Transaction on the system from
Priority 6 to Priority 7. u
MISO’s RC will use NERC EEA-Level 2 to announce the change of the
priority of transmission service of an Interchange Transaction on the system
from Priority 6 to Priority 7. v
ADM-01
MISO will utilize CBM as needed only when experiencing a declared NERC
EEA-Level 2 or higher. w The method to utilize CBM is to elevate an
Interchange Transaction from Priority 6 to Priority 7 per NERC EOP-002 to
maintain the transaction. If a Transmission Constraint still exists (not enough
CBM available), this transaction will be curtailed in the same manner as
other firm transactions.

MISO Market Capacity Emergency
Procedure
RTO-EOP-002-r17
effective date: JUN 01, 2014
The Scheduling and Transmission Services Analyst (STSA) will evaluate all
requests for interchange using CBM by waiving all ramp and market timing
requirements. x
The STSA will approve, as a Transmission Provider, all requests for
interchange using CBM submitted by an energy deficient entity, if the request
is reliable and for a NERC EEA-Level 2.y
The STSA will modify E-tags for interchange using CBM from Priority 6 to
Priority 7 using the following criteria:



Only MISO transmission will be elevated.
Specific interfaces may be prioritized at the direction of the SM.
The STSA will take efforts to prioritize Day-Ahead Market transactions
over real-time Only
The MISO BA also has agreements with neighboring BAs to import
additional energy during such emergencies, as outlined in individual
Balancing Authority Agreements (BAAs).
MISO will post on its OASIS, a notice of the use of CBM at the time of CBM
usage. z MISO will also post a report following the use of CBM that
describes the events that led up to the use of CBM. Customers will be
notified of the circumstances, the amount of CBM that was used, and the
duration of the usage.

3.2
Maximum Generation Emergency Alert
The Maximum Generation Emergency (MGE) Alert provides an early alert
that system conditions may require the use of MISO’s generation Emergency
procedures. MGE Alerts are issued, when time permits, in advance of the
effective period of the alert to allow sufficient time for affected entities to
prepare for anticipated Emergency actions. Actions in the Alert Level are
expected to be implemented by the start of the effective Alert period.
However, when advance notice of the Alert is less than 2 hours,
implementation of actions is expected to be without delay of the start of the
effective Alert period, but no longer than approximately 2 hours.
An MGE Alert is typically issued as a result of one or more of the following
conditions:

The Forward or Intra-Day Reliability Assessment Commitment (FRAC
or IRAC) indicates that economic maximum generation Offers are
within 1% of the Forecast Peak Load plus Operating Reserve
Requirements, or

System conditions dictate a higher conservative margin during DayAhead studies and in real-time.
Transmission constraints may be projected to limit energy transfer such that
an MGE Alert may be required for a sub-area within the MBAA. The area for
which an MGE Alert is declared is the defined Alert Area. Further analysis
will be performed when defining the Alert Area to minimize the likelihood that
actions taken to relieve an Energy Emergency for the same area would result
in system operating limits being exceeded.

MISO Member Alert Level Actions
3.2.1.19 LBAs, TOPs, GOPs and MPs are to refer to the MISO Market Capacity
Emergency Procedure and prepare to implement instructions per this
procedure. All members are to follow their internal communication
protocols.
3.2.1.20 LBAs and TOPs are to refer to MISO’s Conservative System Operations
declaration regarding the suspension of transmission maintenance as
instructed, and GOPs are to reschedule generation maintenance as
instructed by MISO RC.
TOPs and GOPs in the affected area, in coordination with MISO and
their LBA, are to review outage plans to determine if any maintenance or
testing, scheduled or being performed on any monitoring, control,
transmission or generating equipment can be deferred or cancelled,
unless such maintenance will result in improved BES monitoring, control
and reliability. Such maintenance shall be coordinated between MISO
and the applicable entity. If possible, Transmission and Generation
equipment should be returned to service in coordination with MISO, if
such maintenance will not adversely affect the BES. mm
3.2.1.21 TOPs coordinate with LBAs to provide to MISO RC details on any
potential exclusions of constrained pockets within the Alert Area where
there is expected to be adequate generation that may not be transferred
to other parts of the Alert Area because of local constraints. GOPs in the
affected area report to LBAs, TOPs, and their MISO RGD any capacity
limited facilities as they occur and update limits and Offers accordingly.
MPs are to update energy interchange transaction e-tags, sourcing or
sinking, in the MBAA to reflect the firmness of their Capacity Resources
including generator de-rates or units off-line per MISO BPM-007

Resource Scheduling. Schedules that source from a resource that is
identified as a Capacity Resource in Module E for a MISO LSE must be
identified in the tagging process. This also includes a Generation
Resource internal to the MBAA that are identified as a Capacity
Resource for an external BA. This identification allows for proper
curtailment of non-firm imports and exports during a capacity emergency
event.
3.2.1.22 MPs are to communicate with their MISO RGD regarding available
External Resources (Module E registered Capacity Resources) that are
deliverable to the Alert Area. MPs should communicate the amount
available for implementation during the Alert time period. This includes
providing specific instructions on the physical location and path that the
External Resource (s) would use to deliver the energy into the Alert Area.
MISO will provide instructions on when and how much the Market
Participant should schedule into the MISO during Warning Step 1.
3.2.1.23 MPs are to update/ensure accuracy of LMR availability and VLM
information in the MCS Tool
3.2.1.24 TOPs are to coordinate with their MISO RC on potential reliable
reconfiguration options that would increase transfer capability into the
Alert Area and/or that would make available constraint stranded
generation in the Alert Area.
3.2.1.25 LBAs are to ensure that VLM information is up to date in the MCS Tool.
3.3
Maximum Generation Emergency Warning
MGE Warnings are typically declared in real-time, but can be declared on a
forecast basis, to inform Members, LBAs, and TOPs of actual system wide
capacity shortages or transmission related capacity shortages that may
jeopardize the reliable operation of all or any part of MISO’s system. A MGE
Warning is issued as a result of one or more of the following:

Forecasted reserves are less than required; or

Actual Operating Reserves are less than required.

Transmission constraints may be projected to limit energy transfer
such that a MGE Warning may be required for a sub-area within the
MBAA. The area for which a MGE Warning is declared is the defined
Warning Area. Further, analysis will be performed when defining the
Warning Area to minimize the likelihood that actions directed to
relieve an Energy Emergency for the same area would result in
system operating limits being exceeded.
The MGE Warning signals that MISO foresees or is experiencing conditions
where all available economic Resources are committed to meet Load, firm

When MISO issues a MGE Warning, the LBA(s) are thereby informed of the
possibility of Load Shedding. This will ensure sufficient time for:

Notification of interruptible Loads

Preparation and Coordination for public appeals

Preparation for rotating outages

Any other procedures as necessary
Actions include collecting updated information, by LBA, of what Load
reductions would be available via Load Management Measures Stage 1 and
2, and monitoring LMRs availability as entered by MPs in the MCS-LMR
Tool, should the MGE Warning elevate to a MGE Event. Load Management
may include but is not limited to public appeals, voltage reduction, and
interruption of end use loads in accordance with applicable contracts,
demand-side management, utility load conservation measures, and starting
Behind-the-Meter-Generation. *Load Management is separated into LMRs
as registered per Module E, Load Management Measures – Stage 1,
Emergency Demand Response (EDR) Offers, in accordance with Schedule
30, and Load Management Measures – Stage 2.
3.3.1 EDRs may also be registered as LMRs in Module E. If a MP has decided to
offer in all or part of their resource as an EDR for an operating day, the MP
should reduce the availability of that resource as an LMR in the MCS-LMR
Tool for all 24 hours of the same operating day by the maximum MW amount
offered in for that resource as an EDR. In addition, if an MP has
implemented any resources voluntarily, which are registered as an LMR, the
MP should adjust the availability of that resource in the MCS-LMR Tool.
The following are the definitions for the two categories of Load Management
Measures:

Load Management Measures – Stage 1 – Load management actions
that can be taken to reduce demand to preserve or maintain
Operating Reserves that are not EDRs or LMRs.

Load Management Measures – Stage 2 – Load management actions
that can be taken to reduce demand including voltage reductions and
reducing load that, by contract, cannot be interrupted until reserves
are being or are expected to be depleted and energy from
emergency Offers by MPs are being or are expected to be depleted.
These do not include EDRs or LMRs.
*Excludes Registered DRR Type 1 and DRR Type 2 Resources

Maximum Generation Emergency Event
If MISO’s forecasted or real-time energy demand and Operating Reserve
Requirements within the MBAA (or sub-area due to a transmission
constraint) cannot be satisfied with Economic Maximum Limits of all
available Resources, MISO issues a MGE Event due to a shortage of
economic Resources. Transmission constraints may be projected to limit
energy transfer such that a MGE Event may be required for a sub-area
within the Energy Market area. The area for which a MGE Event is declared
is the defined Event Area. Further analysis will be performed when defining
the Event Area to minimize the likelihood that actions directed to relieve an
Energy Emergency for same area would result in system operating limits
being exceeded.
MISO will proceed with the following steps, in order, time permitting, to clear
the Real-Time Energy Market in addition to coordinating Emergency energy
purchases. As conditions require, MISO may provide instructions to move to
any level or step in this procedure while providing instructions to complete
actions described in earlier levels or steps as time permits. Individual
actions in the event level are expected to be implemented without delay and
within approximately 30 minutes of the instruction being given.

Event Termination
3.6.1 When determined by MISO that the short-term forecasted Load in the Market
Area (or sub-area) has returned below (and is continuing below) the sum of
the economic maximums of on-line Resources plus scheduled interchange,
MISO’s SM terminates the MGE Event. Generation Resources should now
verify they have returned to normal economic operating ranges.

Attachment 004: Load Management Update Form
Local Balancing Authorities report via MISO’s Communication System (MCS) or phone to the RC load
reductions that would be available, time permitting, via Load Management should a Maximum Generation
Emergency Event be implemented during the same time frame the Warning is effective. MISO will provide the
expected notification time* for LBAs to assume when completing form.
Load Management may include but are not limited to public appeals, voltage reduction, and
interruption of end use loads in accordance with applicable contracts, demand-side management,
utility load conservation measures, and starting behind the meter generation*.
Load Management is separated into Load Management Measures – Stage 1, , and Load
Management Measures – Stage 2.
LBAs report the following estimated values:
LBA:
Notification time for Load Management
Measures (i.e. < 4 hours)
LMM – Stage 1- available:
LMM – Stage 2 – available:
Total:
10

The following are the definitions for the two categories of Load Management Measures:
Load Management Measures - Stage 1 – Load management actions that can be taken to
reduce demand to preserve or maintain Operating Reserves that are not included in EDRs or
LMRs.

Load Management Measures - Stage 2 – Load management actions that can be taken to
reduce demand including voltage reductions and reducing Loads that, by contract, cannot be
interrupted until reserves are being or are expected to be depleted and energy from
Emergency Offers by Market Participants are being or are expected to be depleted. These
do not include EDRs or LMRs.
