ERCOT Recommends Approval Of Proposed Transmission Line

0

The Electric Reliability Council of Texas (ERCOT) board of directors has endorsed and deemed ‘critical to reliability’ a 345 kV transmission project proposed by Electric Transmission Texas LLC (ETT) from the Laredo area into the Lower Rio Grande Valley. ETT is a joint venture between subsidiaries of American Electric Power (AEP) and MidAmerican Energy Holdings Co.

ETT's proposed transmission project includes the construction of approximately 163 miles of 345 kV transmission lines that will connect ETT's Lobo Substation near Laredo with substations north of Edinburg.

The cost of the project is estimated at approximately $300 million. The ERCOT board recommendation also endorsed the need for AEP Texas to replace conductors on two existing 345 kV lines and upgrade substation facilities at an additional anticipated cost of $225 million.

‘The endorsement from the ERCOT board clearly establishes the need for this transmission project and paves the way for a certificate of convenience and necessity (CCN) application from the Public Utility Commission of Texas (PUCT),’ says Calvin Crowder, president of ETT.

ETT anticipates filing a CCN application from the PUCT in 2012, with completion of the project envisioned for 2016. ETT says it will develop potential routes and conduct environmental studies prior to scheduling open houses to discuss the project with landowners.
