ERCOT Files Report On New, Lower-Cost Alternative To Integrate Rayburn Co-op Load Into ERCOT
ERCOT has filed an updated report with the Texas PUC concerning the sought integration of Rayburn Country Electric Cooperative, Inc.'s SPP load into ERCOT in which ERCOT identifies a new, lower-cost alternative for such integration
ERCOT had noted in a March 1, 2018 filing concerning the integration that it had recently been made aware of an alternative transmission option that might be able to reliably integrate RCEC's load into the ERCOT System at a lower cost than the previously identified Option 2.
ERCOT has now completed its study of this alternative transmission option (deemed the "Modified Alternative Option" in the attached study) and hereby submitted the ERCOT-SPP Coordinated RCEC Integration Analysis — Addendum (Modified Alternative Option Integration Analysis)
As set forth in the filing, ERCOT has determined that RCEC's load can be reliably integrated into the ERCOT System using the Modified Alternative Option. ERCOT has also concluded that the Modified Alternative Option and Option 2 have similar reliability and long-term load-serving capability. However, because the Modified Alternative Option has a lower estimated capital cost than Option 2, ERCOT recommends that the Modified Alternative Option be used for integrating RCEC's load into the ERCOT System. ERCOT's recommendation of the Modified Alternative
ERCOT takes no position as to the appropriate date(s) for integration of RCEC's remaining load into the ERCOT System, nor does ERCOT take a position with respect to the appropriate timeline for any contested case proceedings that may be necessary for approval of the RCEC integration. Further, ERCOT takes no position as to which TSP(s) should construct any transmission option that may be approved by the Commission for integration of RCEC's load.
