PART 2PUBLIC UTILITY COMMISSION OF TEXAS
CHAPTER 25SUBSTANTIVE RULES APPLICABLE TO ELECTRIC SERVICE PROVIDERS
SUBCHAPTER HELECTRICAL PLANNING
DIVISION 1RENEWABLE ENERGY RESOURCES AND USE OF NATURAL GAS
RULE §25.174Competitive Renewable Energy Zones

    (B) A renewable generator shall post collateral equal to $15,350 per MW of its planned project capacity, or $10,000 per MW if the capacity is supported by leasing agreements with landowners that convey a right or option for a period of at least 20 years to develop and operate a renewable energy project based on a conversion factor of 60 acres per MW for a wind energy project.

    (C) A renewable generator planning to build a project in a CREZ shall post collateral with the TSP with which it will interconnect in the CREZ or, if the TSP with which it will interconnect has not been determined, with any TSP that has been designated to build and own transmission facilities for that CREZ.

    (D) A renewable generator may post collateral by providing a cash deposit, letter of credit, or guaranty agreement from an entity with an investment-grade credit rating. A TSP shall require a renewable generator that posts a guaranty agreement to provide another form of collateral if the guarantor loses its investment-grade credit rating or declares bankruptcy. If the renewable generator does not provide another form of collateral, the commission may take appropriate action including seeking administrative penalties.

  (8) A TSP that receives collateral from a renewable generator pursuant to paragraph (7) of this subsection shall handle that collateral in accordance with the following provisions.

    (A) If a renewable generator signs an IA with the TSP and posts any collateral required by the TSP to secure the construction of collection facilities, the TSP shall return to the generator all collateral received from that generator.

    (B) If a renewable generator does not sign an IA with the TSP and post any collateral required by the TSP to secure the construction of collection facilities within 90 days after the TSP notifies it that the transmission system is capable of accommodating the renewable generator's renewable energy facility, the TSP shall retain the collateral received from the generator as an offset to the cost of the transmission facilities the TSP constructs for the CREZ and shall take all reasonable measures to execute any non-cash collateral.

  (9) In a CREZ CCN application, a TSP may propose modifications to the transmission facilities described in a CREZ order if such improvements would reduce the cost of transmission or increase the amount of generating capacity that transmission improvements for the CREZ can accommodate. The commission may direct ERCOT to review modifications proposed by the TSP.

  (10) Findings in Docket Numbers 33672, 35665, and 36146 and the commission's finding in paragraph (5) of this subsection establish that the level of financial commitment is sufficient under PURA §39.904(g)(3) to grant CCNs for transmission facilities designated as a Default Project in ordering paragraph 1 of the Order in Docket Number 36146 and for transmission facilities designated as a Priority Project in finding of fact 136 in the Order on Rehearing in Docket Number 33672. This finding of sufficient financial commitment shall be recognized in all pending and future CCN proceedings for Default and Priority Projects and shall not be addressed further in those proceedings.

(f) Excess development in a CREZ. If the aggregate level of renewable energy capacity for which transmission service is requested for a CREZ exceeds the maximum level of renewable capacity specified in the CREZ order, and if the commission determines that the security constrained economic dispatch mechanism used in the power region to establish a priority in the dispatch of CREZ resources is insufficient to resolve the congestion caused by excess development, the commission may initiate a proceeding and may consider limiting interconnection to and/or establishing dispatch priorities regarding the transmission system in the CREZ, and identifying the developers whose projects may interconnect to the transmission system in the CREZ under special protection schemes.
