PUC Rule

• Pursuant to PUC Subst. Rule §25.505(e) (5), “Load Serving Entities (LSEs) shall provide ERCOT with complete information on load response capabilities that are self-arranged or pursuant to bilateral agreements between LSEs and their customers”

Pricing Events – 2014


• Future improvement – keep y axis same for each graph• ERCOT identified 9 days in 2014 with pricing events … price for 4 or more consecutive intervals exceeded

$200 in all four competitive load zones.

• Graphs compare actual prices on those days to the average price for that day-type and month

Product enrollment changes - 2013 vs 2014 (reported at Feb DSWG)

• Enrollment changes are independent of reporting REP and 2013 Product• Some ESI IDs participating in both 2013 and 2014 changed to a new REP and/or to

different product(s)• Examples:

• An ESI ID on REP A’s TOU product who switched to REP B’s PR product would show up in the middle columns

• An ESI ID that rolled off of all retail DR products by 9/30/14 would show up in left columns

• An ESI ID new to retail DR products in 2014 would show up in right columns

Improvements and lessons learned

Current Categories pg. 1 of 3

Demand Response category (improved) definitions:

RTP – Real Time Pricing - retail prices for all hours or intervals based on ERCOT Real-Time Settlement Point Prices for the premise Load Zone, calculated every 15 minutes, or other real-time wholesale price indicator(s).

BI – Block & Index – fixed pricing for a defined volume of usage, coupled with pricing indexed to the wholesale market for usage exceeding the block. Block prices and volumes may vary by time of day/week. (removed last line from definition - Option could include if usage dips below the block.)

PR – Peak Rebates – a retail offering in which the customer is eligible for a financial incentive paid for load reductions taken during periods of time identified by the LSE, and communicated to the customer during the prior day or the event day, or both. LSE has defined a method to identify whether a customer has responded and to quantify the response amount. Payment (rebate) to customer is based upon customer’s response.•Peak Rebate examples - •No DLC: The REP sends an email one day prior if high prices are forecasted, and sends a reminder text/tweet the morning of the following day. The REP identifies responding customers using a recent similar weather day as a baseline to estimate what the customer’s load would have been. If the customer’s actual load during the predicted intervals was lower than the baseline, the REP agrees to pay the customer $100 / kw of reduction.•DLC: REP sends email one day prior if high prices are forecasted, and sends a reminder text/tweet the morning of the following day. When high prices materialize, the REP sends a signal to the customer’s web-enabled thermostat to increase its set point by 3 degrees. The REP establishes a baseline for the customer to estimate what the customer’s load would have been. If the customer’s actual load during the predicted intervals was lower than the baseline, the REP agrees to pay the customer $100 / kw of reduction.


13


Demand Response category definitions:

CPP – Critical Peak Pricing – prices that rise during critical peaks: limited duration periods of time identified by the LSE that usually correlate to high prices in the real-time wholesale market. Critical peak events may occur a limited number of times per year and typically are communicated a day in advance.

TOU – Time of Use — prices that vary across defined blocks of hours, with predefined prices and schedules. (As used here, does not apply to seasonal adjustments). TOU Example – free evening hours

OLC – Other Direct Load Control – contracts that allow the LSE or a third party to control the customer’s load remotely for economic or grid reliability purposes. This category applies to Direct Load Control (DLC) with different deployment criteria than described elsewhere. (Avoid double counting if DLC data was reported in other categories.). Customer incentive is predefined and does not vary based upon the response.• OLC Example -

•OLC (always has DLC) REP identifies a day on which high prices have, or are about to, materialize. The REP sends a signal to the customer’s web-enabled thermostat to increase its set point by 3 degrees. The REP agrees to pay the customer $10 / month for each summer month, and the customer agrees to allow the thermostat to be set higher 10 times during the summer for periods up to 2 hours long. If the customer overrides the REP thermostat setting during a month, the customer’s payment is reduced by $3.

OTH – Other Voluntary Demand Response Product – any retail product not covered in the other categories that includes a demand response incentive or signal.


14


Demand Response category definitions:

NOTE – will not use 4CP and FO categories for summer 2015 data collection4CP – Four Coincident Peak – predictor signals or direct load control provided to customers in advance of potential Four Coincident Peak (4CP) intervals during summer months (June through September). Reducing load during such intervals lowers transmission charges. 4CP charges apply to large customers (peak demand ≥700 kW) in competitive choice areas, and also to NOIEs at the boundary meter level.

FO – Financial Option – product where LSE purchases an option from the customer that is backed by a specified level of DR and uses it for portfolio trades in the wholesale market.

4CP - ERCOT can do the 4CP analysis without the need to ask the LSEs to provide data in the survey.

FO – category has not been used for 2 years

Lessons Learned

• Lessons Learned / Discussion– Default Peak Time Rebate – presentation that Carl Raish found – – http://c.ymcdn.com/sites/www.peakload.org/resource/resmgr/

2014FallArchive/Schellenberg.pdf

1. Follow-up survey for event identification• Any updates to the survey questions? (links to questions in appendix)• What is the best way to collect this info in the future?• Should the event identification questions continue to be product specific?• Improvement to survey – provide a view to all answers prior to submission or an email

of what you submitted.2. File management

• Some REPs contract with NAESB service providers -- submission of their files may have been delayed as service providers were not aware of need to transmit to ERCOT

• Resubmission to address errors in REP files• Response file vs. validation file• Clean data really helps; multiple error cycles burden all resources

• What other lessons learned would the Market like to add to the list for discussion?

– ERCOT add examples for each of the categories. Post updated category definitions and examples to the Demand Response program page for reference.

– ERCOT provide update to next RMS


18

Snapshot for Summer 2015

2015 Summer data collection timeline•September 30, 2015 - snapshot by REPs for which ESI IDs are in programs•November 4, 2015 - file submission to ERCOT*•November 18, 2015 - error correction file submission to ERCOT

– * pushed file submission back by 2 weeks to allow any error handling to be completed prior to Thanksgiving Holiday

– REP should make all necessary corrections and re-send the full file to ERCOT. ERCOT will use the last file sent for data analysis.

– ERCOT will send survey monkey after receipt of ‘clean data’ or declaring ‘uncle’

•December 1, 2015 – ERCOT will send Survey Monkey links to REPs to gather REP-specific event information•December 11, 2015 – Survey Monkey responses due


19

Next Steps – for future

Still for future discussion•Future years (starting 2016?)

– Evaluate 4 submissions for Summer 2016 (June, July, Aug, Sept)

– Ask REPs to evaluate winter programs for future consideration• Please review categories to see if definitions fit or if new categories

would need to be added

• Consider possible dates and/or frequency of a winter file submission

•Protocol Revision and/or Market Guide Revision?•Review categories each year to see if adjustments need to be made•Review reporting of events via Survey Monkey to see if there is a better method to leverage


20

Take Aways

• REPs – Prepare to take the snapshot for Sept 30th

– Log self-initiated events in preparation for the survey– Map product types to the categories in the guide– If unsure which category to use – please ask

• Carl Raish ([email protected]) • Paul Wattles ([email protected]) • Karen Farley ([email protected])

• ERCOT– Prepare reminder market notice with the dates and send to primary

contacts.– Provide update of 2014 analysis to next DSWG, presentations will

post to DSWG meeting.– ERCOT will continue work on RTP, BI and TOU analysis for future

report to market.
