힐스보로는 전국 데이터 센터 공실률이 0.21%로 낮은 수준을 기록했으며, 지역 내 학교 자금 지원 영향에 대한 커뮤니티 우려가 커짐에 따라 현지 조닝 모라토리엄이 완화되고 있다.

Driving down Brookwood, Evergreen, or along Shute Road reveals a rapidly transforming landscape. Massive concrete data center server farms continue to sprout behind industrial fences, operating around the clock. Rooftop cooling units across Hillsboro consume vast quantities of power and water, underscoring the infrastructure’s intensive resource demands.

Fresh national real estate data confirms what locals have observed firsthand: Hillsboro is nearing capacity in terms of space, power, and bandwidth, even as tech giants compete to secure every available megawatt. According to a commercial real estate report from CBRE covering the first half of 2026, Hillsboro boasts a razor-thin 0.21% data center vacancy rate. This makes it the tightest major data center market in the United States, narrowly surpassing Northern Virginia’s notorious “Data Center Alley,” which sits at 0.24%. For all practical purposes, the city is fully occupied.

Data center capacity is now measured in power draw rather than square footage. Hillsboro’s total inventory stands at 491.4 megawatts (MW), ranking seventh among the nation’s primary digital infrastructure hubs, trailing only Silicon Valley’s 509.2 MW. Nationwide, vacancy across primary markets has fallen to an all-time low of 1.4%, with over 80% of all capacity currently under construction already leased before groundbreaking. In Hillsboro specifically, another 170.3 MW is actively under construction, and CBRE reports that more than 90% of this upcoming buildout is already contracted.

Power is not created in a vacuum. Pushing that volume requires communities to tolerate massive electrical grids featuring wires, substations, transformers, and battery energy storage systems. When comparing market populations to their respective power consumption, Hillsboro emerges as the community most heavily impacted per resident. Current operating facilities in Hillsboro draw 491.4 MW for a population of approximately 111,000, equating to 4.43 MW per 1,000 residents. Including the committed pipeline brings the total to 921.4 MW, or 8.30 MW per 1,000 residents. On a countywide basis, Washington County’s roughly 605,000 residents face 0.81 MW per 1,000 residents currently, rising to 1.52 MW per 1,000 with committed projects. By comparison, Northern Virginia’s metro region (~3.257 million people) averages 1.38 MW per 1,000 residents, while epicenter Loudoun County (~450,000 people) sees approximately 7.11 MW per 1,000. Silicon Valley’s Santa Clara County (~1.9 million) registers 0.27 MW per 1,000, and the combined eight primary U.S. markets (~58 million people) average just 0.19 MW per 1,000.

City Hall recently intervened, implementing a 120-day moratorium on new and expanded data center land-use applications. The pause, which officially runs through November 24, 2026, includes a council option to extend it by another 120 days. The objective is to provide planners time to overhaul the community development code before the city becomes overwhelmed by large-scale industrial facilities. However, significant loopholes remain. Any project that filed land-use applications before July 27 qualifies as grandfathered and may proceed. Additionally, joint disclosures from Portland General Electric (PGE) and GridCARE revealed that the utility leveraged AI-driven grid modeling to unlock an immediate 80 MW of incremental data center capacity in Hillsboro for 2026, as part of a broader initiative to energize over 400 MW by 2029. As reported by Pete Danko of the Portland Business Journal, PGE currently holds contracts for 430 MW across five data center clients.

Demand continues to accelerate. During PGE’s July 31 earnings call, CEO Maria Pope informed Wall Street analysts that the utility has 1.7 gigawatts (1,700 MW) of large-load requests queued for 2028 and beyond. Pope noted that most of these prospective customers are already navigating the local permitting process, having secured grandfathered status before the freeze. Ironically, battery energy storage systems (BESS)—critical infrastructure designed to buffer peak-demand spikes on the local grid—were swept up in the same moratorium restrictions. Meanwhile, regional pushback is growing; Salem’s City Council recently enacted its own data center land-use moratorium following public outcry over a controversial server farm proposal.

While investors celebrate record pre-leasing rates and hyperscale demand, residents contend with tangible consequences: increased traffic, zoning encroachments, heightened water consumption, and substation noise. Proximity to data centers also poses educational challenges. A massive new facility is being constructed within feet of Liberty High School. Researchers studying the intersection of climate, infrastructure, and classroom learning have documented several adverse effects. Studies led by Samantha Kane at Brown University found statistically significant drops in third-grade math scores for students attending schools within one mile of data centers, compared to those located one to two miles away. Schools surrounded by multiple data centers experienced even steeper academic declines. Furthermore, while servers run on electricity, data center campuses typically house extensive banks of industrial diesel backup generators that cycle regularly for testing, releasing fine particulate matter and asthma triggers. Parallel research by UC San Diego’s Josh Aarons indicates that acoustic pollution—a constant, droning low-frequency hum comparable to noise corridors—consistently impairs student cognitive retention and testing performance.
