The U.S. Department of Energy awarded a $250 million investment on Sept. 24, 2026, to the Colorado Energy Office and Xcel Energy to upgrade a vital transmission connection linking Colorado and Texas. The $1.2 billion project, bolstered by additional funding from Xcel Energy, aims to reinforce aging infrastructure, mitigate power outages, and lower consumer electricity costs as regional demand rises.
Upgrading the Colorado to Texas Connection Project
The infrastructure initiative, known as the Colorado to Texas Connection Project (CO2TX), will rely primarily on existing corridors to bridge the gap between the nation’s eastern and western electric grids. Robert Kenney, president of Xcel Energy, Colorado, stated that the upgrade will boost electricity transmission capacity from 210 megawatts to 700 megawatts, with a ceiling capability of reaching 2,000 megawatts without requiring new equipment. This capacity expansion will generate enough electricity to power roughly 500,000 homes.
On the Colorado side, energy will route from Lamar to the high-capacity Sun Valley substation located east of Pueblo. Assistant Secretary for the Office of Environmental Management Timothy Walsh explained at the Arapahoe County Fairgrounds that the project removes a critical regional bottleneck, allowing a higher volume of electrons to flow efficiently across the network. To manage this increased load safely, Xcel Energy will implement advanced technologies such as real-time weather sensors to monitor environmental conditions and dynamically route power away from congested or vulnerable paths.
Mitigating Wildfire Risks and Public Safety Power Shutoffs
The transmission enhancements directly address reliability challenges posed by extreme weather and Public Safety Power Shutoffs (PSPS). In December 2025, Xcel Energy preemptively cut power to tens of thousands of customers west of the Denver metro area to minimize the risk of high winds igniting wildfires, resulting in multi-day outages for certain homes and small businesses. The integration of advanced monitoring tools is designed to reduce the necessity and duration of such emergency disruptions.
The Colorado project forms part of a broader federal initiative. The U.S. Department of Energy’s Office of Electricity is committing nearly $2 billion across 31 grid-improvement projects in 26 states under the Speed to Power through Accelerated Reconductoring and other Key Advanced Transmission Technology Upgrades program. Federal and state officials emphasize that these grid modernizations are essential for handling surging electricity demands driven by population growth, home electrification, and electric vehicle adoption, with Colorado ranking at the top nationally for EV sales in the third quarter of 2025.
