The Short Version

Hillsboro, Oregon, a Portland suburb, already has 35 data centers. These are giant warehouse-style buildings full of computers that run the internet and artificial intelligence. The city has now voted to stop accepting new proposals for them for 120 days.

Nothing already running, being built or under review is affected. What changes is the rulebook for whatever comes next.

The pause also covers big battery sites that store electricity for later. The local power company asked the city to leave those out.

Oregon Public Broadcasting reported that the Hillsboro City Council unanimously adopted a 120-day moratorium on new land-use applications for data centers and battery energy storage system (BESS) sites at a special meeting on Monday, July 27, 2026. It is the first such moratorium in Oregon. Hillsboro has 35 data centers, according to the website Data Center Maps, which is more than any other city in the state. The city says at least seven more sites are under construction or moving through permitting.

The pause does not affect existing data centers or projects whose land-use applications were already submitted. The council may extend it once for another 120 days. The city gave one day’s notice of the meeting, which Mayor Beach Pace said was meant to keep companies from rushing applications in before the cutoff.

Executive Summary

Hillsboro, the center of the cluster of technology firms around Portland known as Oregon’s Silicon Forest, has temporarily stopped accepting new land-use applications for data centers and grid-scale battery sites. The city says it will use the pause to study the facilities’ impacts and amend its community development code to regulate them.

The headline word is moratorium, but the practical effect is narrower. Operating campuses and already-filed projects continue, so Hillsboro’s near-term data center pipeline keeps moving. The lasting change will be the zoning rules that emerge from the study. Those rules will govern every new campus proposed in one of the Pacific Northwest’s most established data center markets, at a time when AI computing demand is driving much of the industry’s new capacity.

The vote also adds to a broader tightening in Oregon. The state has paused new data center tax breaks, approved higher power rates for large users, and set up a governor’s advisory council on data centers.

What the Pause Actually Freezes

The moratorium is narrower than the word suggests. It stops Hillsboro from accepting new land-use applications, which are the zoning filings a developer needs before a project can move through local approvals. It does not touch the city’s roughly 35 operating data centers, and it exempts any project whose application was already on file. By the city’s own count, at least seven more sites were under construction or moving through permitting at the time of the vote. Projects at those stages have, in the ordinary course, already passed the point the moratorium blocks.

Mayor Beach Pace’s reason for calling the meeting on a day’s notice points the same way. The concern was that companies would rush applications in before the cutoff. That suggests the city expected a queue of projects ready to file, and that the pause is aimed at the next round rather than at capacity already committed.

In the near term, then, Hillsboro’s data center footprint keeps growing. The moratorium does not change the buildings going up now. It changes the terms for whatever comes after them.

The Code Rewrite Is What AI Builders Should Watch

The city’s stated goal is to study the impacts of data centers and battery sites and amend its community development code to regulate them. That is the outcome that will last. The moratorium itself expires after 120 days, or 240 if the council uses its single extension. City Attorney Chad Jacobs told the council that state law limits moratoriums to 120 days, and the ordinance allows one renewal. Zoning amendments, by contrast, stay on the books and govern every future application.

For developers, that moves the main risk from delay to design. A four-to-eight-month pause is an inconvenience on a multi-year data center schedule. New siting standards, depending on what they cover, could change which parcels are viable and what a campus must include to be approved. Across the industry, much of the next wave of capacity is being driven by AI computing demand. That typically means larger, more power-dense campuses, which are the projects most exposed to new local rules on land, power and water.

The council has not said what the amendments will contain, and the testimony pulled in different directions. That uncertainty, more than the 120 days, is what a company weighing a new Hillsboro site has to factor in.

Batteries Caught in the Same Net

The most contested decision was to include battery energy storage systems. These are large banks of batteries that absorb electricity when it is plentiful and release it when demand peaks. Portland General Electric and clean-energy advocates asked the council to exclude them. Adam Capage of Renewable Northwest said the facilities “play a vital role in Oregon’s energy future” and already support resilience and affordable electric service in Hillsboro.

Councilors Cristian Salgado and Rob Harris acknowledged that battery sites and data centers are different, though they often come together. They argued the city needs to understand both before writing rules. That is a reasonable argument about order of operations, but it has a cost. Storage is one of the tools utilities use to manage demand peaks as large new loads connect. Pausing new battery applications at the same time as the loads leaves an open question for grid planning in the area during the study period.

A Market Tightening From Several Directions

Hillsboro’s vote follows several state-level changes. Earlier this year the Oregon Legislature enacted a one-year pause on new data center tax breaks through the Enterprise Zone program. In July the Public Utility Commission approved Portland General Electric’s 29.7% rate increase for large energy users, while residential rates fell 1.3%. Governor Tina Kotek has said the state is a “cheap date” for data centers and suggested more changes are coming.

Each measure targets a different cost: taxes, power prices and now land use. Together they show that Oregon is renegotiating its terms for large facilities. The Washington County Chamber of Commerce, the Westside Economic Alliance and three building-trades unions argued for letting established planning processes and the governor’s data center advisory council finish first. Most residents who testified supported the pause. Both positions have merit. The chamber’s point about sequencing is reasonable, and so is the city’s view that it cannot write sound rules for facilities whose local impacts it has not studied.

Background

Hillsboro, in Washington County west of Portland, is the center of Oregon’s Silicon Forest. The area has long been home to semiconductor manufacturing and has become the state’s densest cluster of data centers. Many large operators have received long-running property tax breaks through Oregon’s Enterprise Zone program. Those breaks became a local flashpoint this spring as residents learned how long they would last.

State policy has been shifting as well. The Legislature paused new Enterprise Zone tax breaks for data centers for one year. Regulators approved higher electricity rates for large power users such as data centers under a new state law. Governor Tina Kotek has said Oregon is a “cheap date” for the industry and suggested more changes are coming, and her data center advisory council is still working on recommendations.
