Meter Data

• Submit Meter Data
• Meter Agent Reports
• Market Participant Reports
• Common Questions/Errors

2

Submit Meter Data

• Actual meter values should be submitted in

either 5-minute or hourly intervals as indicated by commercial model registration per each MDSL (Generation, Load, and Interchange)

• Settlement Meter Data reported must

exclude transmission losses (few exceptions)

3

5-Minute Intervals Hourly Intervals

Submit Meter Data (cont’d.)

• MA’s submit Meter Data in MWh via an Application

Programming Interface (API) or Portal within “Open” Meter Data Submittal window: – Initial: OD+1 through OD+4 by noon, unless Saturday or Sunday, then due Friday – Final: OD+30 through OD+44 by noon, unless Saturday or Sunday, then due by Friday

• Both 5-minute and hourly data may be submitted in

same file for a single Operating Day (OD) for different MDSLs. Portal allows for zipped files (API does not)

• Interchange data is submitted hourly (Currently).

4

Submit Meter Data (cont’d.)

• If submitted after closing of initial window, file

processed upon re-opening of window for Final

• Settlement. Submittal after Final Settlement

window closes will require a Dispute to be created.

• After file submitted, MA receives response from SPP

indicating status of submission. If MA determines resubmittal is required, should follow same process as original submittal. – SPP will use latest date/timestamp. – All submittal or resubmittals must be for the entire Operating Day (no empty requests/null intervals)

5

Submit Meter Data (cont’d.)

Meter Data Formatting Standards:

6

Megawatt-hour (MWh) is standard unit of measurement. SPP expects all incoming data to be in XML format. Negative [-] values indicate net injection Positive [+] values indicate net withdrawal Metered data shall be entered, modified, and retrieved solely via XML format.

Submit Meter Data – Input Validation

• Must be for a valid operating day that has ended
• Meter Location must be valid and the meter agent

must have proper certificate.

• Meter Location registration must match hourly/5-

minute submittal data type.

• IntervalEnding values date and time with correct
• ffset: <IntervalEnding>2011-04-01T01:00:00-05:00</IntervalEnding>

*If any input validations fail submitter will receive error message

7

What are the API Messages on meter submittal…

8

• Submit before OD+1

– Message Returned: 1010|Submitted Operating Day Has Not Ended: 2014-09-01 – Status: FAILED

• Submit during Initial Window (Typically OD+1 – OD+4 noon except Sat/Sun Close is due on Friday

noon)

– Message Returned: No Message – Status: PROCESSED

• Submit between Initial and Final Window (Typically OD+4 Noon – OD+30). These files will

automatically process when the Final Window opens.

– Message Returned: The meter data file was submitted between the initial and final windows. The meter data file will not be processed until the final window opens – Status: PENDING

• Submit during Final Window (Typically OD+30 noon – OD+44 noon except Sat/Sun Close is due on

Friday noon)

– Message Returned: No Message – Status: PROCESSED

• Submit after Final Window (Typically After OD+44). These files will require a dispute to be filed with

SPP to process.

– Message Returned: The meter data file was submitted during a closed window. The meter data file will not be used unless a re-settlement occurs for the applicable operating date – Status: PENDING

• Any submittal that fails validation:

– Status: FAILED – Message: the message will provide details on the reason the submittal failed

Market Participant Behavior Risks

9

Meter Data Submission Accuracy – Behavior Description: Market Participants are submitting poor

quality Meter Data – This includes failing to submit any MDSL (Gen, Load, or Interchange) and defaulting to State Estimator.

– Behavior Results: Impacts of poor quality/inaccurate Meter Data:

Directly impacts the MP's Load and Gen related Settlement charges (Asset Energy, Make Whole Payments, Operating Reserve Payments). Indirectly impacts market wide uplift and Revenue Neutrality charges. Over Collected Losses charge is particularly impacted by high Meter Data Calibration due to the shifting of MWs between Load and Gen Settlement Locations inherent in the Calibration MWs. High Meter Data Calibration will affect ALL MP’s in that Settlement Area.

Market Participant Behavior Risks

10

Meter Data Submission Timeliness – Behavior Description: Market Participants are submitting poor

quality Meter Data for Initial Settlement Statement – This includes failing to submit any MDSL (Gen, Load, or Interchange) and defaulting to State Estimator.

– Behavior Results: Incomplete and inaccurate meter submitted for

the Initial Settlement Statement can impact the following:

• Initial Settlement Statement can be more difficult to shadow – Unexpected

charges and deviations due to meter data not matching dispatch.

• High calibration charges across ALL MP’s LOADS in the SA.
• Large swings in money between Initial and Final.
• More Resettlements which impacts the entire SPP market.

Market Participant Behavior Risks

11

Meter Data Submission Accuracy

– Risk Mitigation: Poor quality Meter Data can attribute to many issues within the Integrated Marketplace. Asset owners need to recognize it and validate for themselves that they are submitting quality Meter Data.

• What is quality Meter Data: –

– First, accurate representation of the real MWs submitted during initial meter

• window. produced/consumed/imported/exported.

– Second, correctly signed (+/-) Gen, Load and Tie-line data. Tie-line data in particular must be signed to correctly represent the flow on the given Tie Line location. » Import (-) or Export (+) » Gen (-) or Load (+) – Third, low to zero MWhs of Calibration. Calibration is used to adjust the Load SL in a Settlement Area so that the net of all meter data, tie line data and SE losses is equal to zero MWs. High Calibration results in a shifting of settlement MWhs from the Settlement Location where the MWhs should have been reported to affect the Load Settlement Location.

Near Real Time Meter Reports

Meter Data Reports and Meter Data MP Reports are available via the portal and through API’s and can be generated near real time (currently every 30 minutes) during open meter windows for a given Operating Day:

• Meter Agent Report Card (MA & MP) - provides a point-in-time view for a

Meter Agent into the data processed for a given Operating Day.

• Interchange Report (MA) - point-in-time view for Meter Agents into the data

available for a given Operating Day for all “Tie Line” Meter Data Submittal Locations for which the Meter Agent can submit data and the reciprocal information.

• Calibration Report (MA & MP) - point-in-time view for a Market Participant

into a Settlement Area for a given Operating Day for the Calibration broken into hourly intervals.

12

• If meter data for a settlement location is submitted in Hourly Intervals:

–

The Hourly Qty will display the actual submitted value – The Five Min column will be blank – The Profiled Amount will show Submitted Hourly profiled into 5min increments based on the State Estimator values. 13

Common Questions/Errors

• Many questions/answers can be found in RMS

Knowledge Base.

• For any new Meter Question or issues, submit via

RMS

22

What is State Estimator and how is it used…

State Estimator data from upstream systems creates the best estimate of the actual state of the system based on all SCADA measurement data available and the network model.

Derived by:

• 4-second SCADA data
• Snapshot every 2-minutes
• Overall Network model – (limits, capacities, statistical analysis)

Benefits:

• Fills in missing data
• Helps correct data errors
• Same info used to solve market

23

State Estimator for Settlements is:

 Data based on how the market was solved  Always in 5-minute intervals  Used to profile “Actual” Meter Data submitted in hourly intervals  Used to establish a baseline for Demand Response Load (DRL)  Also used to report Settlement Area Losses

What is Profiling and how does it work…

• Profiling takes hourly submitted quantity and creates 5

minute interval quantities based on State Estimator data.

– Total 5-minute quantity will sum to the submitted hourly quantity – State Estimator does not replace submitted data – Submitted 5-minute quantity is not profiled

24

This example shows 60 MWh submitted for hourly amount and is profiled against state estimator hourly sum of 54 MWh.

* How is Billable Meter Data Created…

25

Actual Meter Data

Profile meter data if submitted hourly Substitute State Estimator Data if missing Add gross-up for Demand Response to Load Settlement Location with imbedded DRR. Adjust top-down (Residual) loads by Settlement Area Losses.

Adjusted Meter Data

Calculate unaccounted for energy within a Settlement Area. Calculate calibration of unaccounted for energy for Load Settlement Locations. Add calibration to “Adjusted” Meter Data.

Billable Meter Data

Pass to Alstom (Settlements System) for calculation. This Amount is used for Energy and other Settlement Calculations

Do I submit 5min or Hourly Data…

Meter Data values are used to calculate a MP’s Settlement activities and which one you submit is based on how the MDSL is registered in the commercial model. You can change MDSL registration, but typically takes a 45 – 60 days. If Meter Agent FAILS to submit for an MDSL, SE data is used.

26

First Choice: Actual 5-Minute Meter Data Second Choice: Actual Hourly Meter Data profiled against State Estimator Data Third Choice: State Estimator 5-Minute Data

Do I need to account for losses…

In the Integrated Marketplace, transmission losses are part of the price, Marginal Loss Component (MLC) and should not be factored in submitting meter data. LMP = Marginal Energy Component + Marginal Congestion Component + Marginal Losses Component Some exceptions based on specific MDSL can exist, for example:

– Distribution Losses – Modeling difference between the MDSL and the Pnode – If the meter for an asset is located at a point different than where the Pnode is modeled, including opposite sides of a transformer, the meter values should be adjusted to account for losses from the meter location and where the Pnode is modeled.
