extra high voltage (EHV) transmission lines
ERCOT
ERCOT stakeholders endorsed a 1,109-mile, single-circuit 765-kV backbone project that is projected to cost nearly $9.4 billion in capital costs, making it the largest initiative in decades.

SPP stakeholders have endorsed the RTO's 10-year transmission plan and some of its proposed 765-kV lines, trimming about $2.5 billion in costs from the portfolio.
SPP
SPP staff have reiterated their position to defer part of the RTO's planned 765-kV transmission overlay, setting aside about $7 billion in regional projects from its 2025 transmission assessment.

A new study warns the United States is not building anywhere near enough high-voltage transmission to support the anticipated needs of the evolving economy.
Admin Monitor
The Texas Public Utility Commission approved a plan that allows ERCOT to authorize the region’s first extra-high-voltage transmission lines and meet the petroleum-rich Permian Basin’s rapidly growing power needs.
ERCOT
The Texas Public Utility Commission’s staff has recommended the commission approve the construction of three 765-kV transmission lines, rather than 345-kV, into the petroleum-rich Permian Basin to improve the region’s reliability.
ERCOT
ERCOT’s plans to continue running a 55-year-old San Antonio gas plant scheduled for retirement are being endangered by "pretty significant findings" that increase costs and delay the schedule.

ERCOT already operates a power system as large as those in several European countries, but demand growth is expected to bring it up to the level of PJM and MISO, which has the industry considering building a new system of 765-kV lines to transmit power around Texas.
PJM
The PJM Board of Managers approved a $6 billion package of grid upgrades that includes expanding the 765-kV backbone east to meet rising demand, particularly in Northern Virginia’s Data Center Alley.
ERCOT
ERCOT CEO Pablo Vegas says the grid operator’s proposal to build more than $30 billion of extra-high-voltage transmission infrastructure is part of a “new era in planning” and just an incremental step from its normal practices.
