Cost Recovery for OOM Down |
(1) Allow for the recovery of Production Tax Credits. This is particularly important for Wind resources since the provision of energy at no cost, as is provided by the current pricing structure, does not provide the ability to recover the lost production tax credits that would have been earned had the Wind resource generated the electricity. (2) Clarify RODP for Wind Resources,. the change will clarify that the RODP found in paragraph 6.8.2.2 (4) for Wind Resources will be zero (same as Nuclear & Hydro). |

SCE Performance Requirement |
To cause QSEs to make better efforts to follow their Resource schedule so that ERCOT can accurately procure Balancing Energy, and to change the allocation of Ancillary Service capacity costs from pure load ratio share to a method that assigns costs to causation. Both reasons are currently of increased importance to assure the operationally smooth implementation of Relaxed Balanced Schedules. |

Liability for QSE default on Obligations to ERCOT |
This revision would allocate responsibility for default of a QSE among Resources and Loads. Currently, only Loads bear the risk for default of an a QSE. This provision would allocate liability across both the generation and load sectors of the market in recognition of the fact that both load and generation engage in market behaviors and make decisions and policies that affect the viability of LSEs in the market. This broader sharing of risk of default of a QSE is a feature of the PJM market and will likely be a feature of the MISO market. Both of these markets have recognized the need to ensure that Market Participants have an incentive to behave in a manner and to promote decisions and policies that are in the best interests of the market as a whole. |

Reduction of OOME Down Payments |
This revision would introduce further Resource Plan analysis by ERCOT between 1600 and 1800 prior to the Adjustment Period. It will require ERCOT to evaluate whether the scheduled capacity from the QSEs Generation Resources may cause transmission security violations during the Operating Day. If the potential for a transmission security violation exists, ERCOT would notify the QSE of the potential issue and the amount of MW in question with the understanding that the QSE, if it receives an OOME DN instruction, would not be paid to back down. This is intended to reduce the Uplift cost caused by a QSE that schedules more output in the Resource Plan than may be possible for the transmission system to absorb without causing a transmission security problem. The PRR does not change the Protocols that compensate generators for OOME Down instructions issued by ERCOT in Real-Time. |

The clawback mechanism reduces the hourly Standby Price paid for RMR Service by the profits earned by operation of any RMR Companion Units located at the same site as the RMR Unit up to the cumulative total hourly Standby Cost incurred. The profits of the RMR Companion Unit(s) are defined as the difference between the MCPE for each interval that the Companion Unit(s) operate and the Resource Category Generic Fuel Cost (RCGFC) for the Companion Unit(s) less the Resource Category Generic Start Cost of the RMR Resource if started during the period in which the RMR Companion Unit(s) operated. |

Balancing Energy Price Adjustment Due to OOMC, OOME and RRS Deployments During Alert and Emergency Notice Conditions |
This PRR is an alternative to PRR 739. It adjusts the Market Clearing Price of Energy (MCPE) when the deployment of Out of Merit Capacity (OOMC), or Out of Merit Energy (OOME) or Responsive Reserve Service (RRS) occurs during an Alert or Emergency Notice condition. This adjustment is similar to that applied to Non-Spin Reserve Service as described in PRR 650, Balancing Energy Price Adjustment Due to Non-Spinning Reserve Service Energy Deployment, which was approved by the ERCOT Board on August 15, 2007. However, in this PRR, these adjustments are effective only during intervals in which an ERCOT-declared Alert or Emergency Notice condition exists. Although ex-post pricing is not a perfect solution, it does allow the market to establish prices during emergency conditions rather than an administratively-set price. |

Remove QSE SCE Performance Exemption for QSEs with only Uncontrollable Renewable Resources On-line |
Stakeholders participating in the special task force on steady state performance metrics for Resources in response to the Public Utility Commission of Texas (PUCT) Staff’s draft Protocol Revision Request (PRR) 586, SCE Performance and Regulation Cost Re-allocation, purposely and temporarily exempted Wind-powered Generation Resource (WGR)-only Qualified Scheduling Entities (QSEs) from the metric they developed in order to focus on the task of building a meaningful metric for all other Resource technologies. This PRR would eliminate that exemption and place WGR-only QSEs on an even playing field with other technologies based on their impact to the system’s reliability and Ancillary Services procured and in recognition of the maturity of the technology to date as evidenced in select white papers promoting WGR provision of Ancillary Services. |
