4.

PGRR028 Evaluation of Compliance of Reactive Requirements. {Defines ERCOT’s process for evaluation proposed Generation Resources’ ability to provide reactive power. Protocol Section 3.15, Voltage Support, defines reactive capability requirements for Generation Resources. Paragraph (3) of Protocol Section 16.5, Registration of a Resource Entity requires ERCOT to opine upon the capability of the proposed Generation Resource’s ability to meet those requirements.}

  1. ROS in Nov 14 meeting referred PGRR028 back to PLWG to address issues with language in Section 5.6.1(3).
  2. Request for greater clarity regarding defining what future conditions must be met.
  3. PLWG considered language at November meeting and tabled for consideration of revised language to be offered at December PLWG mtg from a small group led by ERCOT.  
  4. ERCOT will present an update to proposed language.

6.

Constrained Generation.

ROS directed PLWG to consider existing conditions where generation is constrained from delivery to the grid. The question was raised whether system upgrades should be identified to increase access to grid for constrained generation throughout ERCOT; and whether decisions to upgrade be solely based on current reliability or economic criteria. ERCOT’s work to assess potential system upgrade to relieve potential future congestion in Panhandle (PREZ studies), while no similar assessment of existing constrained generation in ERCOT, was offered as an inconsistency in addressing generation congestion on the ERCOT grid.

  1. An initial discussion to best define the concern will be held.
  2. A review of current Planning Guide, Protocol and PUC Substantive Rule language is on-going within the PLWG to serve as a basis for identifying what is currently the required planning responsibilities for ERCOT and TSPs.   
  3. ROS discussed the on-going working group activity at the March ROS Meeting for the purpose of providing additional guidance to the PLWG and identified a proposed plan for the Stakeholders to consider in the March PLWG Meeting and any subsequent follow-up PLWG working group meeting.

7.

The following is a proposed plan offered by ROS Chairman (Bill Hatfield) as a result of the March ROS Meeting discussion.

  • Review ERCOTs August 2013 presentation titled 2017 Generation Deliverability Analysis. Review the process and methodology for performing the study, determine if changes in process or criteria should be applied, and make a recommendation as to the value of performing the study on an ongoing basis.
  • Review the Interconnection Request Process document and identify any limitations with the process that could limit generation deliverability.
  • Document ideas for maximizing existing generation deliverability.
  • Provide periodic updates to ROS and document any simplifying assumptions.
  • Prioritize all recommendations and seek ROS review and direction.
  • Focus on recommendations that can be resolved by procedure modifications, PGRRs, NOGRRs, and NPRRs.
  • Post all group meeting notices to the PLWG, RPG, and ROS listserv to maintain transparency in the review process.
