TITLE 16ECONOMIC REGULATION
PART 2PUBLIC UTILITY COMMISSION OF TEXAS
CHAPTER 25SUBSTANTIVE RULES APPLICABLE TO ELECTRIC SERVICE PROVIDERS
SUBCHAPTER CINFRASTRUCTURE AND RELIABILITY
RULE §25.55Weather Emergency Preparedness

      (iv) Includes any additional information required by the ERCOT protocols in effect as of April 1 of the year in which the declaration is submitted; and

      (v) Includes a notarized attestation sworn to by the generation entity's highest-ranking representative, official, or officer with binding authority over the generation entity attesting to the completion of all applicable activities described in paragraph (2) of this subsection, and to the accuracy and veracity of the information described in this subparagraph.

    (C) A generation entity must submit the appropriate declaration of preparedness to ERCOT prior to returning a mothballed, outaged, or decommissioned resource to service during the winter or summer season. For any new or repowered resource, a generation entity must submit the appropriate declaration of preparedness prior to the resource commissioning date established in the ERCOT interconnection process for resources.

  (4) No later than December 20 of each year, ERCOT must file with the commission a compliance report that addresses whether each generation entity has submitted the declaration of winter weather preparedness required by paragraph (3)(A) of this subsection for each resource under the generation entity's control.

  (5) No later than June 20 of each year, ERCOT must file with the commission a compliance report that addresses whether each generation entity has submitted the declaration of summer weather preparedness required by paragraph (3)(B) of this subsection for each resource under the generation entity's control.

  (6) ERCOT will treat declarations of preparedness and associated information submitted by a generation entity as Protected Information as defined by the ERCOT protocols

(d) ERCOT inspection of resources.

  (1) ERCOT must conduct inspections of resources and may prioritize inspections based on factors such as whether a resource is critical for electric grid reliability; the length of time since the resource was last inspected; has experienced a forced outage, forced derate, or failure to start related to weather emergency conditions; or has other vulnerabilities related to weather emergency conditions. ERCOT must determine, in consultation with commission staff, the number, extent, and content of inspections, provided that every resource interconnected to the ERCOT power region must be inspected at least once every three years. ERCOT must develop, in consultation with commission staff, a winter weather inspection checklist and a summer weather inspection checklist for use during resource inspections. Inspections may be conducted by ERCOT's employees or contractors.

    (A) ERCOT must provide each generation entity at least 72 hours' written notice of an inspection unless otherwise agreed by the generation entity and ERCOT. The written notice must identify each ERCOT employee, commission staff member, or designated contractor participating in the inspection. Within 24 hours of receiving notice of inspection, a generation entity must provide ERCOT, commission staff, and designated contractors all generation entity requirements for facility access. Upon provision of the required written notice, a generation entity must grant access to its facility to ERCOT and to commission staff, including an employee of a contractor designated by ERCOT or the commission to conduct, oversee, or observe the inspection.

    (B) During the inspection, a generation entity must provide ERCOT, commission staff, or designated contractors access to any part of the facility upon request. ERCOT, commission staff, and designated contractors must comply with all applicable safety and security regulations, including those maintained by the generation entity, during the inspection. A generation entity must provide access to inspection, maintenance, and other records associated with weather emergency preparation measures and must make the generation entity's staff available to answer questions. A generation entity may escort ERCOT, commission staff, and designated contractors at all times during an inspection. During the inspection, ERCOT, commission staff, or designated contractors may take photographs or video recordings of any part of the facility except control rooms and may conduct interviews of facility personnel designated by the generation entity. Documents, photographs, and video recordings collected or generated by ERCOT, commission staff, or designated contractors during or related to the inspection will be treated as confidential information under applicable state or federal laws and regulations.

  (2) ERCOT inspection report.

    (A) ERCOT must provide a written report on its inspection of a resource to the generation entity. The written inspection report must address whether the generation entity has complied with the requirements in subsection (c)(1) or (2) of this section.

    (B) If the generation entity has not complied with a requirement in subsection (c)(1) or (2) of this section, ERCOT must provide the generation entity a reasonable period to cure the identified deficiencies.

      (i) The cure period determined by ERCOT must consider what weather emergency preparation measures the generation entity may be reasonably expected to have taken before ERCOT's inspection, the reliability risk of the resource's noncompliance, and the complexity of the measures needed to cure the deficiency.

      (ii) The generation entity may request ERCOT provide a longer period to cure the identified deficiencies. The request must be accompanied by documentation that supports the request.

      (iii) ERCOT, in consultation with commission staff, will determine the revised cure period after considering a request for a longer period to cure the identified deficiencies.

    (C) ERCOT must report to commission staff any generation entity that does not remedy the deficiencies identified under subparagraph (A) of this paragraph within the cure period determined by ERCOT under subparagraph (B) of this paragraph.

    (D) A generation entity reported by ERCOT to commission staff under subparagraph (C) of this paragraph will be subject to enforcement investigation under §22.246 of this title (relating to Administrative Penalties). A violation of this section is a Class A violation under §25.8(b)(3)(A) of this title (relating to Classification System for Violations of Statutes, Rules, and Orders Applicable to Electric Service Providers) and may be subject to a penalty not to exceed $1,000,000 per violation per day.

(e) Weather-related failures by a generation entity to provide service. ERCOT must notify a generation entity and commission staff of the generation entity's repeated or major weather-related forced interruption of service. Upon notification from ERCOT, the generation entity must contract with a qualified professional engineer to assess its weather emergency preparation measures, plans, procedures, and operations. The qualified professional engineer must not be an employee of the generation entity or its affiliate. The qualified professional engineer must not have participated in previous assessments for the resource for at least five years, unless the generation entity provides documentation that no other qualified professional engineers are reasonably available for engagement. The qualified professional engineer must conduct a root cause analysis of the failure and develop a corrective action plan to address any weather-related causes of the failure. The generation entity must submit the qualified professional engineer's assessment to the commission and ERCOT within 15 calendar days of receiving the assessment. A generation entity to which this subsection applies may be subject to additional inspections by ERCOT. ERCOT must refer to commission staff for investigation any generation entity that does not comply with a provision of this subsection.

(f) Weather emergency preparedness reliability standards for a TSP.

  (1) Winter season preparations. By December 1 each year, a TSP must complete the following winter weather preparation measures for its transmission facilities. A TSP must maintain these measures throughout the winter season and complete any ongoing requirements at the appropriate time. If necessary to come into compliance, a TSP must update its winter weather preparation measures no later than one year after ERCOT files a historical weather study report under subsection (i) of this section.

    (A) Implement weather emergency preparation measures that could reasonably be expected to ensure the sustained operation of all cold weather critical components during winter weather conditions. Where appropriate, such measures may be implemented using either personnel or automated systems. Such measures include, as appropriate for the facility:

      (i) Confirmation of the operability of all systems and subsystems containing all cold weather critical components;

      (ii) Confirmation that the sulfur hexafluoride gas in breakers and metering and other electrical equipment is at the correct pressure and temperature to operate safely during winter weather emergencies, and perform annual maintenance that tests sulfur hexafluoride breaker heaters and supporting circuitry to assure that they are functional; and
