EILS Submission Form• Feb – May 2010 Procurement

Incorporated changes based on feedback during the Oct 2009 – Jan 2010 procurement cycle

One form for all phases of EILS Format streamlined – “R” tabs More flexibility for Alternate Baseline Resources Pre-populated workbooks provided by ERCOT

Use of “All_Alt” tab Qualify individual loads for the Alternate Baseline Allow them to be mixed and matched into Resources ERCOT provided composite “All_Alt” tab – all loads submitted and okayed in RIDs (R-tabs and All_Alt

tabs) Same generic RID Number assigned to all submissions

R-tab with Alternate Baseline Selected Analyze Default and Analyze Alternate fields ignored during RID process Unique RID Number assigned if okayed No load changes allowed if submitted as a Bid Any combination of ‘Yes’ and ‘No’ allowed for Analyze Alternate fields when bidding

ERCOT worked with QSEs to correct and re-process most RIDs rather than rely on E-Mail exchange

Greatly reduced volume of errors – easier for both QSEs and ERCOT!

Discussion of any issues related to the form and/or RID-Bid Process?

5

EILS Submission Form Form Changes Being Implemented --- MINOR!

Applicable for remainder of Feb – May 2010 Contract Period Reinstatements Substitutions Preliminary Baseline Reviews

Applicable for Jun – Sep 2010 Procurement Process

Added cell with drop-down list on Identification Tab to code purpose for submission

Renaming “All_Alt” tab to “Alt” tab … to avoid confusion with “All_Alt” and “All Alt” Purpose and usage remain the same

Addition of an Address Field for each load To help track loads over their participation in EILS

Applicable to loads in both competitive and NOIE areas To facilitate tracking loads with multiple sites e.g. chain stores Distinct street address and city required … blank or incomplete addresses will be treated as errors

Flexible Tab Names Identification Tab – no change – must be included Alt Tab – revised name (see bullet above) may be deleted or just left blank during RID process Resource Tabs (formerly R-tabs) – free-form names allowed

ERCOT will provide Pre-populated forms with Resource Names used as tab names ERCOT will return okayed RID forms with Resource Names used as tab names Note: Excel limitations on

tab name length (30) Characters not allowed: & : | ? ? * [ ]

Eliminated Tab Count cell on Identification Tab

EILS Submission Form

Open Form and Discuss Changes Note: posted form will only be usable for

Preliminary Baseline Reviews New RIDs for Procurement Reinstatement RIDs Substitution Pre-Qualification RIDs

Questions / Comments on Changes?

Meter Data Submittal

Three sources of interval data for EILS Registered TDSP in competitive area

NOIE TDSP

QSE installed metering

8

Meter Data Submittal

Data from a Registered TDSP

NOIE Settlement Metering Points included Normally interval data will be pulled from ERCOT’s Settlement System and

used for EILS analysis QSE premise level metering will be ignored if TDSP interval data is available When a new TDSP IDR meter has been installed at a premise

Interval data may be available to the TDSP but not in ERCOT’s Settlement System QSE should make arrangements with the TDSP to have load data submitted to

ERCOTdo not wait until the end of the contract period

Submission outside the TX Set process (before IDR profile change takes effect) Data must be in a prescribed format No affidavit required from TDSP Missing data will be treated as zero for availability, automatic failure for event/test

performance

9

Meter Data Submittal - continued

Data from a NOIE TDSP QSE responsible for arrangements with NOIE TDSP to have load data

submitted to ERCOT Monthly submission in a prescribed format required

Data from QSE-Installed Metering Premise level data from a NIDR load or sub-metering data from either an IDR

or NIDR load Accuracy consistent with PUC Substantive Rules and ERCOT Protocols Affidavit from P.E. required ERCOT will validate against IDR or NIDR data in Settlement System If sub-metering a premise within a NOIE area, QSE must make arrangements

with the NOIE to have premise level billing data (IDR/NIDR) sent to ERCOT for validation purposes

Monthly data submission in a prescribed format required 35 days after last day of calendar month

Missing/invalid data will be treated as zero for availability, automatic failure for event/test performance

10

Meter Data Submittal - continued

Important Interval Data Submission Deadlines

March 7 – data for the October-January Contract Period

April 4 – data for month of February

May 5 – data for month of March

Reinstatement Procedures for Suspended Loads

Deadline Action

Feb. 22 Final day for the QSE to submit a corrective action plan for any EILS Resource(s) desiring to be reinstated

Feb. 26 Deadline for QSE on behalf of EILS Resource to submit a Reinstatement Resource ID using the standard EILS Submission form

Mar. 5 ERCOT staff provides baseline assignment options and capacity pre-screening information back to the QSE

Mar. 8

QSE submits a Reinstatement Bid using the standard EILS Submission form, indicating a MW capacity offer, Minimum Base Load (MBL), and baseline selection (if a choice is available), but not price Resource is subject to a full load-shed test as soon as the Reinstatement Bid is submitted; test procedures will be the same as an annual test, via a VDI thru the QSE hotline

April 22

ERCOT returns test results to the QSE. This may occur earlier, depending on the timing of meter data submission. If the resource is found to have failed the test, it will be ineligible to bid into the upcoming Contract Period. If the resource passes the test, it will be eligible to bid and will not be subject to another test for 365 days unless it is re-bid as part of an aggregation that is materially different from the original resource.

April 27 Final day to submit a formal Resource ID for the June-September 2010 Contract Period

May 6

Bid due date. Bids for reinstated EILS Resources must adhere to the parameters described in the Technical Requirements & Scope of Work. ERCOT may reject or modify the MW capacity value or MBL if it determines these values are not supported by historical meter data or are inconsistent with prior bidding practice for that resource.

Reinstatement Calendar Posted at http://www.ercot.com/services/programs/load/eils/index

13

Reinstatement Procedures for Suspended Loads• Resource submitted for reinstatement does not have to match the

suspended resource identically– May exclude one or more loads and include other loads

• If Resource passes the load-shed test– Eligible to bid in the upcoming Contract Period

• RID submission not required– No load-shed test for 365 days– No changes allowed to load configuration after Reinstatement Bid– MW capacity ≤ amount on Reinstatement Bid– Minimum base load ≥ amount on Reinstatement Bid– Load, MW Capacity and Minimum Base Load changes allowed in subsequent

procurement cycles

• If Resource fails the load-shed test– Ineligible to bid in the upcoming Contract Period– Ineligibility continues until a test is passed

• Questions Regarding Reinstatement

14

Substitution Procedures

ERCOT may limit the number of substitutions for a resource during a contract period

Substitution must be pre-qualified Registered and qualified LAAR Previously qualified EILS resource which has passed a test in last

365 days Reinstated resource – no load changes allowed Loads from a currently obligated resource (resource augmentation)

Substitution limited to that specific resource Resource composed of loads from one or more previously obligated

resources and/or new loads with no previous EILS participation No pre-qualification test required if at least 80% of the load in the

resource from resources which have passed a test in last 365 days

Otherwise passing a pre-qualification test required

15

Substitution Procedures - continued

Pre-qualification Process

QSE must submit EILS Resource Submission form to ERCOT as a Pre-Qualification RID

ERCOT responds with baseline assignment options and test status (required or not required for pre-qualification) and capacity pre-screening information

QSE submits EILS Resource Submission form to ERCOT as a Pre-Qualification Bid

Baseline selection, MW capacity and minimum base load

ERCOT administers test if needed and reports results to QSE

16

Substitution Procedures - continued

Substitution Process

QSE notifies ERCOT via email of substitution Identify resource being replaced and substitute resource to be used Begin date and estimated end date for period of substitution

Substitution is for complete calendar days only May be for one or more time periods Substitution may begin no earlier than hour ending 01:00 of the next

calendar day following ERCOT receipt of notification

Attached EILS Resource Submission form as Substitution Bid MW capacity same as resource being replaced Minimum base load ≥ pre-qualification bid MBL Substituted and replaced resources must have same baseline type

Alternate to alternate Default to default, but default type (Regression, Mid 8 of 10, MDP) does

not have to match

Appendix A due to ERCOT within 3 days of email notification

17

Substitution Procedures - continued

Periods of unavailability may be submitted for a substitution During the substitution period, availability status of the substituting resource

overrides status of the replaced resource 2% limit on allowed unavailability with 5 business day notice applies to the

combined availability status

For alternate baseline resources, the average load excluding the minimum base load for a time period limited to 150% of the original capacity MW

If the availability factor for one or more time periods during the contract period is less than 95%, all loads in the original and substitute resources are subject to being treated as having failed to perform

In a deployment event, the resource obligated at that time is subject to deployment requirements

Substitution resources may be subject to unannounced load-shed tests Warning: For default baseline resources, time is of the essence for a

substitution to be useful If load in 5% or more of the obligated intervals is below Capacity MW +

MBL, before the substitution takes effect, the resource will fail regardless of the substitution

18

No changes to unavailability procedures Revised form has been posted … reduced

size Form should be submitted regardless of

whether a substitution has or will occur

Unavailability Procedures

19

Testing Procedures

No changes to testing procedures QSEs are reminded to submit meter data as

soon as possible following a test Resources with missing data for a test will be

treated as having failed the test
