ERCOT Update


On May 19th,  ERCOT posted a Market Notice that ETT will be taking its 345kV CREZ transmission lines in west Texas out of service on a rolling basis for maintenance work and possibly to replace structure components “as part of a warranty claim.” These outages involve the following transmission elements:

·         Edith Clark to Clear Crossing

·         Riley to Edith Clark

·         Tesla to Riley

·         Tesla to Edith Clark

·         Clear Crossing to Dermott

·         Clear Crossing to West Shackelford

These circuits link the Panhandle wind development zones with the central CREZ network and the ERCOT system more broadly. ERCOT expects these outages to last through November 2018. These outages, in areas of the grid that already are experiencing congestion and increased loading, could make it more difficult for wind generation to reach the ERCOT market.

Last week, TAC issued a market notice that ERCOT will host a webex and conference call on July 15th for interested parties to ask questions about these outages. Parties may submit questions ahead of time by sending them either to their respective ERCOT Account managers or to  ERCOT will post questions its website and post an updated market notice once the questions and other information are posted.The call information is below.
