Overview

GridLiance West will upgrade transmission lines and substations in southern Nevada. The upgrades will replace existing transmission lines, improving the reliability and resilience of the electrical grid for customers in Nevada. Transmission lines will be built in portions of Nye County and Clark County to dependably power homes and businesses and reduce service interruptions.

Like other transmission lines in Nevada, GridLiance West will finance, construct, own, operate and maintain these projects while working closely with the local community and key stakeholders. The projects require regulatory and permitting approvals at the federal, state and county levels. Upgrades are expected to be in service no later than 2027.

The GridLiance West transmission upgrades will significantly enhance the electric energy system in the region, alleviating current constraints in the delivery of reliable power.

Benefits

Direct Investment for Nevadans

Upgraded transmission lines are vital for improving power reliability in Nevada. Due to the age and limited capacity of the current transmission lines, these upgrades are necessary to minimize the potential for power outages. The project will greatly benefit Nevada, generating immediate economic impact for the region, creating hundreds of local jobs and providing ongoing support for local businesses and communities.

Project Specifics


GridLiance West’s compact design minimizes environmental and visual impacts and provides the most value to customers with safe, reliable and cost-effective components and materials. The existing rights-of-way will be used where possible to minimize impacts to local landowners.

This project will include upgrading the Trout-Canyon-Sloan Canyon line to a 500kV double circuit line and replace an aging 230kV line from Trout Canyon-Desert View.

Below is the expected timeline of the project.

  • Q2 2025: Permitting and Procurement will be completed. Construction will begin.
  • Q4 2027: The project will be in service. Construction will be complete.
