The Texas Public Utility Commission has postponed action on Oncor Electric Delivery’s resiliency plan, the first from a state utility under new legislation.

Texas regulators have approved ERCOT’s reliability plan for the petroleum-rich Permian Basin that could rely on the state’s first use of 765-kV transmission facilities.

Texas regulators are narrowing in on a reliability plan for what one said will be a “monumental infrastructure buildout” and could include 765-kV transmission to meet growing petroleum and data center demand in West Texas.

SPP is considering a 765-kV solution and several 500-kV proposals in its Permian Basin footprint in Texas and New Mexico as it dabbles with extra-high-voltage transmission lines.

ERCOT told Texas regulators its initial reliability study of the Permian Basin indicates “substantial amounts” of transmission projects will be needed to meet its projected load by 2038.
