||Entergy Texas Substation Update
PORT ARTHUR, September 1, 2017 - Aftermath of Hurricane Harvey is significantly impacting Entergy’s ability to restore power to customers in some areas. Several of Entergy Texas’ substations, which distribute electricity to customers over large areas, are experiencing outages due to flooding. Unlike distribution lines and poles, substations are much more complex parts of the grid. Substations consist of advanced equipment including electronics and computers that monitor and re-route power instantaneously through high-speed relays and equipment that protect the electric system. Restoration of these affected locations is being hampered as workers are unable to access these areas or assess equipment that remains under water. When flood waters recede and it is safe to do so, Entergy workers will evaluate damage and begin restoration.
- We’re in the process of scouting our 41 substations in southeast Texas via aerial patrols and specialized vehicles to monitor and verify damage.
- As of Thursday, Aug. 31, water has affected 13 substations.
- In facilities where we know water is inside the substation, we are developing project plans and ensuring materials are available to repair or replace equipment as soon as it’s safely possible after waters recede.
- Until substations can be returned to service, we will continue to monitor and assess conditions. We will also look for options to reroute power so restoration efforts can continue where it is safe to do so. Customers can expect extended outages until water recedes and we have the ability to assess both conditions and repair time of these complex facilities. Some of these areas are currently under mandatory evacuations.
- We’re also working to restore 35 transmission lines, covering approximately 218 line miles.
