CenterPoint Energy (NYSE:CNP) on April 2 said that its 60-mile, 345-kV Brazos Valley Connection project in Texas was energized on March 29.
The line – which runs from Grimes County through Waller County, ending in Harris County, Texas – is the southern portion of the Houston Import Project, the company said.
A company spokesperson on April 2 told TransmissionHub that the two substations involved are the Gibbons Creek substation, owned by Texas Municipal Power Authority, and the Zenith substation, owned by CenterPoint Energy.
CenterPoint said in its statement that its total project capital cost is about $285m, in line with the estimated range of about $270m to $310m in the Public Utility Commission of Texas’ original order regarding the project. The estimated impact to a residential customer within CenterPoint’s service territory using 1,000 kWh per month is less than 20 cents per month, the company said.
CenterPoint noted that ERCOT in 2014 identified the 130-mile, 345-kV Houston Import Project as critical to providing additional transmission capacity to import power into the Houston area by June 2018. The Houston Import Project runs from Limestone County to Harris County, the company said.
