June is National Safety Month, and at Platte River, safety is a core part of who we are. Our commitment was recently recognized by APPA for Gold‑level safety performance, reflecting a low total recordable injury rate, strong leading and lagging indicators and disciplined reporting and inspection practices. This recognition highlights what we see every day: accountable leadership, engaged employees and continuous improvement embedded into our safety culture. We’re proud to be recognized for advancing safety and helping define industry‑wide safety priorities. Thank you to everyone for their hard work in helping Platte River excel in safety. #NationalSafetyMonth #SafetyCulture #APPA #PlatteRiverPower

Not all energy costs are directly comparable. Platte River’s approach helps account for: ✅ Total system cost ✅ Reliability during peak and extreme events ✅ Long-term affordability The goal is not just lowest upfront cost, it’s the lowest cost to reliably power our owner communities over time.

How does electricity actually get to your home or business? Let’s connect the dots 👇 Electricity starts at our generation resources—like Rawhide Energy Station and our hydro, wind and solar sites across the region. From there, it travels across our high-voltage transmission system to a network of 28 substations throughout Northern Colorado. ⚡ This is where our owner communities take the baton. At the substation, the power is stepped down to a lower voltage and handed off to the local utilities in Estes Park, Fort Collins, Longmont and Loveland. From there, those utilities distribute electricity directly to homes and businesses. Think of it like this: We deliver the power to the community They deliver it to you This structure is unique to how we operate as a joint action agency—providing wholesale power on behalf of our owner communities, who handle local distribution. Different roles, one shared mission: reliable power for the communities we serve.

So… what actually happens at Rawhide vs. headquarters? Now that we’ve covered how our locations are connected, let’s break down what happens at each one 👇 📍 Rawhide Energy Station This is where a lot of our electricity is generated. Teams here operate and maintain our power resources and help them deliver energy when it’s needed. 📍 Headquarters (Fort Collins) This is where teams support the bigger system—everything from system operations and planning to engineering, finance and community engagement. We also have generation resources located across our system—including hydro, wind and solar—that operate off-site from both of these locations. Different roles, different locations—but all working toward the same goal. Why not have everything in one place? Generation needs to be where it makes sense physically, while coordination, planning and central support back these efforts and keep it all one smooth system. Generating power is just one part of delivering it reliably to our communities.

I can see into the future, and it’s bright! Our new 100 MW battery will help keep it that way—and no, it’s not just the reflection off the hard hats. We’re so excited to have broken ground on this significant project for Platte River and our owner communities.

Having some employees based at Rawhide and others at our headquarters means strong internal alignment is essential—especially when it comes to project updates, engagement and shared goals. Each month, we bring everyone together through a company-wide meeting to stay connected. On the same day, we host one session bright and early at Rawhide, followed by another that afternoon in our Energy Engagement Center at headquarters. These meetings highlight the many projects that are moving our organization forward, aligned with the goals of our Resource Diversification Policy, adopted by our board of directors in 2018. As we continue transitioning to a more renewable-based generation mix while maintaining reliable, quick-start assets, staying aligned across teams is key. That means our substation crews based out of headquarters know what the combustion turbine planners at Rawhide are working on—and everything in between. At the end of the day, it all works together to deliver reliable power to our four owner communities.

Breaking ground, building the future ⚡ Weld Energy Storage will store up to 100 MW of energy and deliver it when it’s needed most, boosting reliability as we continue toward a renewable energy future. Thank you to NextEra Energy Resources and our Platte River team who helped make this milestone possible! Read all about it: prpa.org/weld-storage/

Wait… so Rawhide Energy Station IS Platte River Power Authority? YES! Rawhide is one of the facilities owned and operated by Platte River Power Authority, and everyone who works there is a Platte River employee. And we completely understand where the confusion comes from. 📍 Rawhide is north of Wellington, while our Platte River headquarters building is in Fort Collins. Because we’re community-owned, our headquarters is located within one of the owner communities we serve. While each employee is typically stationed at one location or the other, many of us regularly travel between sites. Same employer ✅ Different location ✅ Stay tuned for more clarity on our organization’s structure! #PublicPower

Powering our owner communities spans far beyond just helping keep the lights on. Platte River employees are proud to support blood donation efforts at both our Rawhide Energy Station and headquarters—helping neighbors in need and strengthening the communities we serve. Giving back is part of who we are. ❤️

Take a look at race day from our 7th annual NoCo Time Trials! This solar- and battery-powered car competition is one of our favorite annual events. It showcases the innovation and excitement fueling the next generation of energy leaders. It keeps growing in popularity. This year, we had approximately 450 guests in attendance! Thanks to everyone who made this a fun-filled day.🚗⚡

🚲⚡ Happy National E-Bike Day! E-bikes are becoming increasingly popular as more people can get around in new, efficient ways. Every ride still depends on something behind the scenes: reliable power. At Platte River, we’re proud to help keep that power flowing for our four owner communities, whether it’s fueling homes, businesses or the ride across town.

Plot twist: it's baby season 🐄 Every spring, about 25 bison calves join the herd at our Rawhide Energy Station's range land, and they're obviously stealing the spotlight. We'll get back to market transition and battery storage updates soon… but for now, we're soaking up the fluffy cuteness.

Today, we honor and remember those who gave their all for our freedom. We recognize the sacrifices made and express our deepest gratitude to those in our owner communities and beyond. Wishing you a peaceful Memorial Day. #HonorAndServe

I'm walking on sunshine! 🎶 ☀️ Well, our generation load certainly is. After a particularly rainy week, our solar fields are coming back to life! For the first time ever, Black Hollow Sun, the largest solar project in northern Colorado, is producing power at its maximum output of 257 MW. Combined with existing solar installations at Rawhide Energy Station, this means that over half of our power production for Platte River's system is generated directly from the sun, and a whopping 81% of our energy production right now is coming from renewable sources. Platte River continues toward its deep decarbonization goals and commitment to reliable, environmentally responsible, financially sustainable power.

A smart infrastructure investment in the 1990s is still making a difference today. Platte River built its fiber network to support a reliable electric system. It has grown into a resource that supports broadband expansion, public safety, healthcare connectivity and more across the region. 👉 Learn more: prpa.org/other-news/how-plat…

After more than a decade of improving combustible dust safety at Rawhide Energy Station, one moment at an industry conference brought the importance of that work into sharp focus. When nearly two-thirds of attendees raised their hands to say they had experienced a dust explosion, and many involved injuries or worse, it reinforced what Platte River teams already knew: the risks are real, and the work matters. From early system upgrades to a fully modernized dust collection approach, the commitment never wavered—even with Unit 1’s retirement ahead. Safety doesn’t sleep, and protecting people always comes first. 👉 Read the full story: prpa.org/other-news/a-show-o…

Just your average #SelfieSaturday. Nothing to see here. Carry on.
