GridLiance West Breaks Ground on 155-Mile Nevada Transmission Project

GridLiance West, a subsidiary of NextEra Energy Transmission, LLC, joined federal, state and local leaders in Jean, Nevada, on September 9, 2026, to mark the start of construction on the GridLiance West Core Upgrades Project, NextEra Energy announced. The project comprises approximately 155 miles of new 230-kilovolt and 500-kilovolt transmission lines and new and upgraded substations in Nevada.

NextEra Energy describes the project as a long-term investment in Nevada’s energy future, designed to replace existing infrastructure and expand transmission capacity so that homes, businesses and industries have access to reliable and affordable electricity. According to the announcement, the project represents 500 jobs created during construction, an estimated $90 million in property and sales tax revenue, and an estimated $553 million in annual economic impact.

Project Route and Line Work

The transmission lines will be built in portions of Nye County and Clark County, according to the Core Upgrades project page, which states the work will replace existing transmission lines, dependably power homes and businesses and reduce service interruptions. The Bureau of Land Management states the upgrades will be built on the west side of the Spring Mountains from Las Vegas to Pahrump and Indian Springs.

The work includes upgrading the Trout Canyon-Sloan Canyon line to a 500-kilovolt double-circuit line and rebuilding the existing 230-kilovolt Trout Canyon-Northwest line to double circuit. GridLiance West states its compact design minimizes environmental and visual impacts and that existing rights-of-way will be used where possible to minimize impacts to local landowners. The company states the upgrades will significantly enhance the electric energy system in the region and alleviate current constraints in the delivery of reliable power.

GridLiance West will finance, construct, own, operate and maintain the projects, which required regulatory and permitting approvals at the federal, state and county levels. The project page attributes the estimated $90 million in property and sales tax revenue to an Economic and Fiscal Impact Analysis Socioeconomic Assessment by Triple Point Strategic Consulting, measured over the approximately 40-year life of the project and during construction, and states the revenue could help fund schools, roads and other public services.

Permitting Record and Construction Timeline

The Bureau of Land Management approved the 155-mile project on June 7, 2026, covering the upgrade of an existing single-circuit 230-kilovolt system to a double-circuit 230-kilovolt or 500-kilovolt system in Clark and Nye counties. The approval authorizes GridLiance West, LLC, to construct, operate, maintain and eventually decommission the upgraded power transmission line and new, expanded or modified substations, switchyards and access roads.

The project page’s posted timeline lists permitting and procurement completed in summer 2026, with construction beginning that season; construction complete in fall/winter 2027; and the upgrades in service no later than 2028. The NextEra Energy announcement states the project will be completed in mid-2028.

Matt Valle, president of NextEra Energy Transmission, said in the announcement: “This is a significant investment in Nevada’s energy future and demonstrates the critical role transmission infrastructure plays in powering homes, businesses and industries.” He added that economic growth depends on reliable, affordable electricity and the infrastructure needed to deliver it, and that the groundbreaking reflects what can be achieved through strong collaboration among industry, government and local communities.

Nevada Governor Joe Lombardo said the project is another important step toward securing Nevada’s energy future and strengthening the state’s position as the energy hub of the West. He said reliable, affordable energy is essential to supporting Nevada’s growing economy, creating good-paying jobs and attracting new investment.

Katie Jereza, Assistant Secretary of the U.S. Department of Energy’s Office of Electricity, said the project will add another 1 gigawatt of capacity to Nevada’s electric grid, providing access to affordable and reliable electricity across the state. She said the upgrades to transmission lines and substations will boost local economies with construction jobs, annual economic impact and tax revenue that benefit schools, emergency services and public infrastructure.

Robby Hamlin, chief executive officer of Valley Electric Association, said the member-owned cooperative gains access to significant transmission investment, expertise and resources through its collaboration with GridLiance West while remaining locally governed. He said connecting to a larger transmission network through the Core Upgrades Project will strengthen system reliability, enhance resilience and support the continued growth of the region the cooperative serves.

NextEra Energy Transmission, LLC, reports more than 3,200 miles of transmission lines in development and operation in 19 states and Canada. The company is a subsidiary of NextEra Energy, Inc. (NEE ), which the announcement describes as the largest electric power and energy infrastructure company in North America.

According to the announcement, when the project is completed in mid-2028 the expanded transmission network will unlock access to additional energy resources, create opportunities for new industrial investment and generate tax revenue for local communities that will help support schools, emergency services and public infrastructure.
