Staff of the Texas PUC issued a list of questions for public comment concerning development of a reliability standard
Staff questions are as follows:
(1) The Commission has previously considered various reliability metrics, such as Loss of Load Expectation (LOLE), Loss of Load Hours (LOLH), and Expected Unserved Energy (EUE).
• Which reliability metrics, including those not previously studied, should the Commission consider in establishing a reliability standard for the ERCOT power region?
• Which reliability metric, or combination of reliability metrics, should the Commission adopt for the reliability standard in ERCOT?
• What are the advantages of your chosen reliability metrics, and what are the disadvantages of alternative approaches?
(2) What is the most effective way that the Commission can include deliverability in the reliability standard?
(3) Additional considerations in establishing the reliability standard in the ERCOT power region.
• Should the reliability standard include a locational requirement?
• Should the reliability standard include a seasonal component?
• How can extreme events be captured in a reliability standard?
• How can the value of distributed energy and load resources be captured in a reliability standard?
(4) How frequently should the Commission update the calculation of the requirement necessary to meet the reliability standard?
• What criteria should help determine the frequency of the update?
(5) If you have any industry or academic papers on the topic and best practices that you believe the Commission should review while establishing the reliability standard for the ERCOT power region, please provide them.
