  1. TX SET Update to RMS March 14, 2007

  2. Drop to AREP Changes PUCT Project 33025 • One of TX SET 2007 goal is to evaluate approved Rulemakings and determine their Transactional and Market impacts to current processes: • RULEMAKING TO AMEND COMMISSION SUBSTANTIVE RULES CONSISTENT WITH §25.43, PROVIDER OF LAST RESORT (POLR) Project 33025 was approved on February 16, 2007 • One of the many changes in this project included the elimination of the Drop to AREP process (814_10 TX SET transaction)

  3. Drop to AREP - What is Changing? • EffectiveMarch 8, 2007, Competitive Retailers shall no longer send 814_10 Drop to AREP transactions to ERCOT. • In response to the adopted rule: • TX SET will submit to RMS our recommended changes to Protocols Sections 15 and 19 concerning the 814_10 Drop to AREP transaction. • Texas Test Plan Team has eliminated the Drop to AREP Test Script from CR Market Certification testing effective with Flight 0407 • Market Metrics Working Group will continue to provide quarterly reports of the number of 814_10 Drop to AREP transactions received by ERCOT. Re-evaluation of 814_10 Drop to AREP reporting will be conducted once the new Performance Measures rule is introduced.

  4. Market Process for Solar & Wind Devices • In an effort to conserve on their electrical usage by using environmentally safe devices, Retail customers are purchasing and installing wind and solar equipment on their residence and in some cases the premise may even be their place of business. With solar panels/cells these types of devices have shown to reduce the amount of usage that is recorded at the billing meter, as well as, based upon the amount of consumption may generate an output of electricity onto the utility’s distribution line.

  5. New Technology Creates New Issues • TX SET discussed some of the following issues at a high level and came to the conclusion that these issues are BIGGER than TX SET: • Currently TX SET 867_03 Monthly Usage does not support negative values in usage • Some TDSPs will not allow a bi-directional meter to run backward – NET Zero because their distribution wires were utilized for both the input and the output of the electricity. • Guidance is needed from Competitive Metering/Metering Working Groups to determine what type of metering equipment should be utilized for this type of application. • The REP of Record may want to know exactly how much electricity was generated by the Retail Customer’s equipment to pass onto the customer any savings information.

  6. New Technology Creates New Issues • Does the CR expect to be Settled on the electricity generated? If yes, what are the Settlement implications and how would the information be communicated? • Do the current Protocols support Solar and Wind producing equipment? • Could this type of premise require a change or addition to the Load Profile Assignment because of the frequent fluctuation of usage? • Where should this issue belong because it may cross into both the Retail Market and Commercial Operations Subcommittees? • Are there Wholesale implications as well?

  7. New Technology Creates New Issues • These customers are more than likely to be residential or small commercial type premise where the customer is looking for cost savings to their bottom line while in that process of trying to benefit from tax incentives, we would hope that these ESI IDs would not be treated as a Load Acting As a Resource (LaaR) because: • The customer would encounter additional cost that was not expected or anticipated that would more than dilute their cost savings from installing the solar and wind device. • LaaR require special metering equipment at a cost that is traditionally higher than a standard meter. • This type premise may be required to obtain a QSE while their generation, if and when produced, is very minimal to none at times based upon their individual consumption for that billing period.

  8. Conclusion • TX SET was unable to provide a proposed solution (long-term or short-term) due to the numerous issues that needed to be discussed and resolved by various parties. We would like to request that the Market discuss these issues to determine a Market process where all can enjoy the benefits of solar and wind devices, especially the Retail Customer.
