CBA RTGEN (AGC):

FUNCTIONALITY

Section 2

5

CBA RTGEN (AGC) System - NEW

• CBA will install new AGC module for SPP EMS

– Impact to Members

• Will no longer use member AGC for controlling generation

– Delivery of Market resource setpoint instructions will come from SPP CBA RTGEN (AGC)

• Delivered over ICCP – setpoints and supporting data (including

but not limited to; regulation reserves, contingency reserves and Energy, etc.) – Compliance Issue for Member AGC (current BA)

• If setpoint instructions are delivered through the member AGC

system – certain security measures must be implemented

6

CBA RTGEN (AGC) – Member Impacts by type

• Members are impacted differently depending upon Type of

CBA/Market entity

– Current Balancing Authorities with EMS/AGC

• Affected by use of AGC, tie line meters and setpoint delivery
• Most connectivity is already available but may not be at necessary

periodicity of data transfer

– CBA Area/Market Resource Owners (non-BA)

• Affected by ability to receive setpoint delivery directly to generators
• May have connectivity issues depending upon old BA contracts

– CBA Area/Market Non-Resource Owning Market Participants

• RTGEN and ICCP changes should have no impact on this category of

Market participant

7

RTGEN (AGC) – Delivery of Setpoint Instructions

SPP AGC will:

• Receive dispatch signals from the Integrated Marketplace

Real-Time Balancing Market (RTBM) on a 5 minute basis (Reg. Up, Reg. Down, Spin Deploy, Sup Deploy, etc by resource).

• Calculate ACE every 4 seconds (NERC requirements

calculation at least every 6 seconds)

• Use similar programming logic to the Marketplace, to

calculate real-time adjustments to the dispatch signals

• Deliver Set point instructions to Resources

8

RTGEN (AGC) – Impact for Current BAs

• Members will modify their AGC package, in order

to no longer control generation

– Disable ACE calculation – Ensure that SPP setpoint instructions to resources cannot be modified

• Members have already been notified of these

changes and have begun necessary work and coordination with vendors

• Member AGC changes and related testing must be

completed before Market Trials

9

RTGEN (AGC) – Compliance Issues for Current BAs

• SPP CBA must be able to prove that it can control

generation resources throughout the BA Area

– Current BAs must be able to prove that they will not (and cannot) modify the setpoint instructions sent to resources by SPP – NERC will audit these functions during the SPP CBA certification process

• SPP legacy BA with EMS/AGC systems will undergo audit type

verification from the SPP RE on their level of control of generation

10

RTGEN (AGC) – Compliance Issues for non-BA Resource Owners

• SPP CBA must be able to prove that it can control

generation resources throughout the BA Area NERC certification

• Resource-owning members who do not currently own an

EMS will also need to receive their setpoint instructions

– Many of these entities (i.e. IPPs and Cooperatives) receive their EIS instruction through their current BA – Current BAs are not required to and may not be willing to continue using their equipment to deliver setpoint instructions

• SPP CBA staff will be contacting each individual IPP and

Cooperative to determine if changes will be necessary

11

RTGEN (AGC) – Issues for Non-Resource Owner Market Participants

• SPP CBA RTGEN change should not have any impact on

non-resource Owner Market Participants

• SPP CBA ICCP changes should not have any impact on non-

resource owner Market Participants

• SPP CBA staff will not be contacting non-resource owners

related to RTGEN or ICCP changes.

• If you are not sure if you are affects by these systems

please contact Shari Brown – contact information provided at the end of the presentation.

12

RTGEN (AGC) – Resolution of Issues

• Each type of member will be impacted differently
• No two BA will have the same impacts
• No two non-BA Resource Owners will have the same

impacts

• Decisions on Resolution of issues need to be made within

the next 2 months.

• Each individual member (BA and Non-BA Resource Owners)

will be Contacted by SPP staff before May 1, 2012

• Resolution of issues will be coordinated directly between

the SPP and the members

13

ICCP:

FUNCTIONALITY

Section 3

14

ICCP – Types of data transfers

• 1. Setpoint Instruction Data (from SPP AGC to Resources)
• 2. Actual Generation Data (from Resource Owners to SPP

EMS)

• 3. Actual Interchange tie line Data (from Transmission

Operators to SPP EMS

• 4. Actual tie line meter Data

(between Market Participants)

15

ICCP – Setpoint Instructions from SPP

• SPP AGC will calculate setpoint instructions, and

send setpoint instructions to generation resources

• Most resource owners will not be required to

make ICCP changes related to receiving setpoint instructions

• Additional supporting information will create

additional data point transfers

• Potential for ICCP changes due to Marketplace

Protocol section 4.2.2 for regulation-qualified resources

16

ICCP – Actual Generation Data to SPP

• Will continue to be used by SPP EMS, Forecasting,

Integrated Marketplace and Settlements

• Currently some resources provide this data over ICCP,
• thers via XML
• SPP does not anticipate resource owners being required to

make many ICCP changes related to providing actual generation data

• However, there is potential for ICCP changes due to

Marketplace Protocol section 4.2.2 for regulation-qualified resources

17

ICCP – Regulation Qualified Resources

• Section 4.2.2 of Protocols, “Offer Submittal” states that a

regulation qualified resource must have

“ . . . the necessary equipment installed to be able to respond to Automatic Generation Control on a 4-second basis, including telemetering that can be scanned and updated

• n a 2-second basis; . . . ”
• This market requirement is specific to Resources that will

be offering Regulation and Contingency Reserves into the market

• This is specific to the capability of that resource and the

telemetry related to the resource

• The requirement is to ensure that resource data is available

and scan able by SPP every 2 seconds.

18

Actual Interchange tie line data

• SPP CBA will have approximately 200 interchange tie lines

with First tier BAs.

• SPP already receives data over ICCP for all tie line data

from member entities (current BA).

• NERC requires specific periodicity of data flow to SPP CBA

EMS in order to calculate ACE (BAL-005 R16)

• Data flow periodicity for tie line data is inclusive of the

equipment from the RTU > ICCP > SPP ICCP/SCADA.

• The data flow from the RTU to the SPP RTGEN ACE

must be delivered at the same rate at which ACE is calculated

19

Actual Interchange tie line data – periodicity

• Research indicates that some member entities may have to

change the data delivery rate to meet NERC requirements

• SPP will be working with each current Balancing Authority

to test and determine adequate settings for the entire path for each interchange tie line

• ICCP changes for tie lines make up a finite data set that will

need to be changed; not ALL data sent between SPP and the members

• Members need to determine if they can make their system

changes to ICCP data sets or if they need to contact ICCP vendor to determine how to change only necessary datasets.

20

Actual tie line data (internal to member entities)

• SPP CBA will not be responsible for tie lines between old

legacy Balancing Authorities (they are no longer NERC Interchange tie lines for the SPP BAA).

• However, SPP EMS modeling, the Integrated Marketplace

and settlements will continue to use tie line data between market participants

• Tag Agents will still provide the tie line meter data between

the market participants

• TOP will continue tie line verification processes for

settlement, but not for CBA requirements

21

Confirming Bandwidth Availability

• Bandwidth relates to the amount of data that can be

transferred at any time

• Current BAs using SPPNET today should not be

concerned with bandwidth issues.

– SPP research indicates all entities are using SPPNET, although it is not an SPP requirement to do so

• SPP Network department constantly monitors data

flow over SPPNET

• Entities should keep in mind that only actual

interchange tie line data and resource data is subject to a specific periodicity

22

ICCP Next Steps

• SPP will work with each individual ICCP member to get the

most efficient settings on their ICCP configuration.

• Most ICCP changes relate to periodicity of data flow and

additional data points

• There are multiple configuration options for ICCP, so it is

best for SPP to work on each issue separately to address individual needs – Example: one option is report by exception (as opposed to set periodicity)

• Entities should be thinking about contacting their vendors

if they utilize a vendor for their ICCP connectivity

23

CBA RTGEN/ICCP Deep Dive Summary

• Members are impacted differently depending upon Type of

CBA/Market entity

– Current Balancing Authorities with EMS/AGC

• Affected by use of AGC, tie line meters and setpoint delivery
• Most connectivity is already available but may not be at necessary

periodicity of data transfer

– CBA Area/Market Resource Owners (non-BA)

• Affected by ability to receive setpoint delivery directly to generators
• May have connectivity issues depending upon old BA contracts

– CBA Area/Market Non-Resource Owning Market Participants

• RTGEN and ICCP changes should have no impact on this category of

Market participant

24

ICCP – Types of data transfers

1. Setpoint Instruction Data – Most Resource Owning Market Participants should see little change unless not currently connected directly to SPP EMS 2. Actual Generation Data – Most Resource Owning Market Participants already have connectivity, some periodicity changes may be required 3. Actual Interchange tie line Data – Only current BAs for periodicity of data transfer 4. Actual tie line data – Only current BAs, no known changes necessary from a CBA perspective

25

Timing for Resolution of ICCP Issues

• All entities currently in the EIS

– Need to resolve any issues before Market Trials begin in May 2013. – SPP will be contacting each entity this spring (months) to determine agreed upon actions related to ICCP

• Entities (not in EIS) that are not registered for the

Integrated Marketplace by June 1, 2012

– SPP CBA staff will be notified once they are registered and will contact the entity to begin taking care of ICCP issues. – There is a lead time of at least six months for new ICCP links. – The entity will be only allowed to enter Market Trials after connectivity is complete
