Entergy’s (NYSE:ETR) Entergy Texas, Inc., energized the 25-mile, 230-kV China-Stowell Transmission Project on May 1, Entergy said on May 2.
Stuart Barrett, vice president of customer service for Entergy Texas, said in the statement, in part: “This new line will help relieve congestion on the ‘transmission highway,’ as well as provide more resilient infrastructure that directly benefits customers across Southeast Texas.”
The Public Utility Commission of Texas approved the line route along with Entergy Texas’ application for a certificate of convenience and necessity in May 2017, Entergy said.
Kacee Kirschvink, sr. communications specialist, Entergy Texas, on May 6 told TransmissionHub that the project’s estimated total cost is about $66m.
Entergy said in its statement that Entergy Texas also recently rebuilt 25 miles of the existing 138-kV line from the Newton Bulk substation in Newton to the Leach substation near South Toledo Bend.
Kirschvink said that the estimated total cost of the Newton Bulk-Leach Transmission Line Upgrade project is $23m.
Those upgrades began in 2018 and the line went into service on May 1, the company said in its statement, adding that that project is part of the Western Region Economic Project, which includes a new 230-kV line in Montgomery and Walker counties. It is designed to provide Entergy Texas customers better access to lower-cost power sources, as well as upgrade the electric transmission system to more effectively move low-cost power into and within the Southeast Texas area for all customers served from Entergy Texas’ transmission system, the company said.
Of the 230-kV line in Montgomery and Walker counties, Kirschvink said that the Rocky Creek-Lewis Creek line is expected to be completed in summer 2020.
Over the next three years, Entergy Texas is investing more than $2bn to power the future of Southeast Texas, with that work including construction of a new power plant, transmission lines, substations, and distribution enhancements to transport electricity to nearly half a million homes and businesses, Entergy said.
