Boulder's Power Struggle: Why Burying Power Lines is Just the Beginning
Boulder’s power grid is in crisis, and it’s not just about the occasional flicker during a storm. The city is grappling with a perfect storm of challenges: aging infrastructure, escalating wildfire risks, and a climate that’s growing increasingly unpredictable. Xcel Energy’s recent push to bury power lines is a step in the right direction, but it’s only scratching the surface of a much deeper problem. Personally, I think this is a wake-up call for cities everywhere—a stark reminder that our grids were built for a different era, and they’re struggling to keep up.
The Underground Solution: A Band-Aid or a Breakthrough?
Xcel’s undergrounding projects, like the one along U.S. 36 and near the wastewater treatment plant, are certainly necessary. Burying lines reduces wildfire risk and protects critical infrastructure. But here’s the catch: undergrounding isn’t a silver bullet. What many people don’t realize is that while buried lines are less likely to spark fires, they come with their own set of challenges. Outages can be harder to locate and repair, and the process of undergrounding is slow and expensive. If you take a step back and think about it, Boulder’s current pace of undergrounding could take 70 years to complete. That’s not a solution—it’s a stopgap.
What this really suggests is that Boulder needs a more holistic approach. Undergrounding is part of the answer, but it’s just one piece of a much larger puzzle. The city’s power grid is a patchwork of old and new systems, layered over decades of growth. This complexity exacerbates outages and confusion, as neighboring homes can be on entirely different circuits. One thing that immediately stands out is how vulnerable Boulder is to wildfires, especially with lines running through high-risk corridors in the foothills. The 2009 Olde Stage Fire, likely sparked by an energized powerline, is a haunting reminder of what’s at stake.
The Bigger Picture: Climate Change and Grid Resilience
Here’s where things get particularly fascinating: Boulder’s power struggles aren’t just about outdated infrastructure—they’re a symptom of a changing climate. Historically, Boulder’s winters were wet enough to reduce the risk of downed lines sparking fires. But increasingly dry winters have stripped away that natural buffer. This raises a deeper question: How do we future-proof our grids in an era of extreme weather?
Xcel’s $2 billion wildfire mitigation plan is a step forward, but it’s reactive rather than proactive. In my opinion, utilities and cities need to think beyond burying lines or upgrading poles. We need to reimagine the grid itself. Distributed energy resources like battery storage and neighborhood microgrids could provide resilience at a local level. Imagine if Boulder’s neighborhoods could operate independently during outages—it’s not just a pipe dream; it’s a necessity.
The Human Cost: Who’s Left in the Dark?
What makes this issue even more urgent is the human cost of unreliable power. Boulder residents experienced nearly twice as much downtime as the rest of Colorado in 2024. For people who rely on electric medical equipment or small business owners, these outages aren’t just inconveniences—they’re life-threatening. A detail that I find especially interesting is how Boulder is now focusing on vulnerable populations in its resilience planning. Mobile home residents, for example, are often overlooked in these conversations. This shift in focus is long overdue.
The Road Ahead: A Patchwork or a Plan?
Boulder’s power resilience roadmap is ambitious, but it’s also a test of political will. Accelerated undergrounding, microgrids, and backup power systems all sound great on paper, but they require funding, cooperation, and time. From my perspective, the city’s biggest challenge isn’t technical—it’s logistical and financial. How do you prioritize projects when everything feels urgent? And who pays for it all?
What’s clear is that Boulder can’t afford to wait. The Marshall Fire of 2021, partially caused by an Xcel powerline, was a wake-up call. Public safety power shutoffs have become a new normal, but they’re a blunt tool. They protect against wildfires but leave thousands in the dark. This tension between safety and reliability is something cities across the West are grappling with.
Final Thoughts: A Grid for the Future
If there’s one takeaway from Boulder’s power struggle, it’s this: We can’t keep patching an outdated system. The grid of the future needs to be resilient, decentralized, and adaptable. Personally, I think Boulder has an opportunity to lead the way, but it requires bold thinking and even bolder action. Burying power lines is a start, but it’s just the beginning. The real question is: Are we willing to rethink everything?
In a world where climate change is rewriting the rules, the status quo isn’t an option. Boulder’s grid crisis is a cautionary tale, but it’s also a call to action. Let’s hope the city—and others—are listening.
