Imagine wind turbines soaring higher than the famous Space Needle in Seattle—now picture them possibly interfering with air traffic at Washington's third-largest airport. This isn't just a tall tale; it's a real debate unfolding in Kennewick, where the balance between green energy and community safety hangs in the balance. But here's where it gets controversial: is this ambitious project a step toward a sustainable future, or a risky gamble that could ground essential flights? Let's dive into the details and explore why local voices are raising alarms.
In a bold move, Republican Representative Dan Newhouse from Washington has urged the Federal Aviation Administration (FAA) to revisit its assessment of the proposed Horse Heaven wind project, located near Kennewick. This initiative, backed by Scout Clean Energy and already greenlit by the state under former Governor Jay Inslee, has sparked significant worries about its effects on aviation safety. 'There's still a lot of unease regarding how it might affect secure and dependable air operations,' Newhouse stated recently. He insists that a thorough second review of the FAA's earlier 'no hazard' ruling is crucial to truly evaluate the project's influence on the local community. For newcomers to this topic, the FAA is the U.S. government agency responsible for regulating and ensuring the safety of civil aviation, so their stamp of approval—or lack thereof—is pivotal in projects like this.
And this is the part most people miss: the wind farm's evolution. Scout Clean Energy received state siting approval to develop a sprawling array of turbines across about 24 miles of the Horse Heaven Hills, stretching just four to six miles from key Tri-Cities towns like Richland, Kennewick, Pasco, West Richland, and Finley, and even closer than that—under two miles—from Benton City. Opposing group Tri-Cities CARES has highlighted that Scout recently submitted plans to the FAA's Obstruction Evaluation Group for 141 turbines reaching an impressive 671 feet in height. This proposal seems to supplant an earlier one for shorter turbines, around 500 feet. To put that in perspective, think of a wind turbine as a giant propeller on a tall tower that harnesses wind to generate electricity—much like how a pinwheel spins in the breeze, but scaled up enormously. The original turbines at the nearby Nine Canyon wind farm clock in at about 300 feet, so these new ones represent a significant upgrade in scale.
Why the shift to taller turbines? Since Scout's initial state site certification application in early 2021, which included various options for turbine counts and heights, the industry standard for wind farms has tilted toward structures exceeding 500 feet. These allow for capturing more wind energy at higher altitudes, potentially increasing efficiency. But here's the twist: perched on a ridgeline that rises 1,500 to 2,000 feet above the valley floor, these 671-foot behemoths would loom large over the landscape, according to Tri-Cities CARES. From the ground below, they could dramatically alter scenic views, but more critically, Newhouse warns of possible severe repercussions for the airspace.
Diving deeper into the airspace worries, this region isn't just any spot—it's a hub for vital air travel. The Tri-Cities Airport, Washington's third-busiest, relies on this airspace for commercial flights, and the wind farm site is roughly 10 miles away. Additionally, air ambulance services from northeastern Oregon frequently use these routes to reach Kadlec Regional Medical Center in Richland, the area's sole Level II trauma hospital. Level II means it handles a broad range of emergency cases, so timely air transport can be life-saving. Newhouse emphasized these points in his correspondence to FAA Administrator Bryan Bedford, noting that turbines rivaling the Space Needle's height could also disrupt Department of Defense military training paths and the deployment of large air tankers for battling wildfires.
Newhouse's appeal follows a series of letters from nine Washington state lawmakers in September, as well as communications from Tri-Cities CARES in September and November. These were directed not only to the FAA but also to Defense Secretary Pete Hegseth and Transportation Secretary Sean Duffy. Tri-Cities CARES delved into specifics, pointing out that military training routes and restrictions border the Horse Heaven Clean Energy Project on its southern and western sides. Navy aircraft from Whidbey Island Naval Air Station often traverse this airspace for exercises. Moreover, massive firefighting planes stationed at Grant County International Airport are essential for taming swift wildfires on the steep terrains near the Tri-Cities, including the Horse Heaven Hills Resource Area managed by the U.S. Bureau of Land Management. For context, aerial firefighting involves dropping water or retardants from the sky to contain blazes—imagine a plane swooping in like a superhero to protect homes and forests.
Even more alarming, Tri-Cities CARES noted that some turbines could be as near as 4.1 miles from the helipad at a Kennewick hospital. 'No venture of this magnitude and spread has ever been constructed so proximal to a major urban center—with over 320,000 residents—anywhere in the United States,' they stated, citing the combined populations of Benton and Franklin counties. As the fastest-expanding metropolitan region in Washington beyond Puget Sound, air traffic here is expected to grow with increasing demand.
Now, the spotlight turns to former Governor Jay Inslee, a Democrat who signed off on the project in September 2024. This approval came after the Washington State Energy Facility Site Evaluation Council revised its recommendations, responding to Inslee's directive to prioritize the urgent need for clean energy sources. The project encompasses not just wind turbines but also solar panels and battery storage systems. All the letters criticizing the approval target Inslee for overriding initial council restrictions and proceeding despite pushback. State legislators' missive highlighted that the project was approved 'despite objections from the host county, local businesses, the tribal community, and a majority of residents.' They argued that 'those most familiar with the region have vehemently resisted for numerous reasons, including issues that should concern our federal allies, like aviation security, possible limitations on military activities, and worries about impaired aerial firefighting for wildfires threatening urban zones.' Signatories included Republican Senators Matt Boehnke from Kennewick and Perry Dozier from Waitsburg, along with Republican Representatives Stephanie Barnard from Pasco, April Connors from Kennewick, Skyler Rude and Mark Klicker from Walla Walla, Chris Corry from Yakima, and Deb Manjarrez from Wapato.
Newhouse accused Inslee of sidelining community anxieties and aviation risks in favor of the permit. Tri-Cities CARES echoed this in their November letter, claiming that Washington's drive for renewables, largely propelled by the ex-governor, has 'apparently trumped everything else.' Scout Clean Energy has yet to respond publicly. But here's a controversial angle: in an era of climate urgency, should the pursuit of renewable energy—crucial for reducing carbon emissions—take precedence over local safety and traditional uses of airspace? Or is this a case where 'green' initiatives might be cutting corners too aggressively?
