Mountain Branch AI Energy Campus.Shape the AI economy on our terms.
Whether this AI campus is built here or somewhere else, the AI economy is coming to Harford County. Mountain Branch is a chance to decide the rules now: power, water, noise, setbacks, environmental review, and community benefits.
This proposal exists because the old data center model created legitimate public concerns.
Residents are right to ask about grid strain, water use, noise, air quality, and who pays for infrastructure. Mountain Branch should be judged by whether those concerns are written into enforceable approval standards, not by whether the word "data center" appears on a sign.
"Will this push costs onto ratepayers?"
Legacy grid-reliant campuses can create new utility demands and public concern about who pays for upgrades.
The proposed model uses self-supplied, behind-the-meter power as the primary operating structure, with limited utility interaction only for approved construction, startup, protection, and reliability needs.
"Will this drain public water or damage streams?"
Older evaporative cooling designs can consume significant water and raise discharge concerns.
The proposed campus is designed around closed-loop, air-cooled, or similar low-water cooling for routine operations, with water and discharge conditions written into the approval framework.
"Is this really compatible near homes?"
Residents reasonably worry about industrial equipment, backup generators, lighting, and 24-hour operations.
The power concept uses modular solid oxide fuel-cell technology rather than a traditional combustion turbine or diesel-generator primary-power model, paired with setbacks, screening, acoustic modeling, lighting controls, and enforceable operating limits.
AI capacity is becoming basic economic infrastructure.
The same computing capacity that powers national security, medical research, manufacturing, agriculture, logistics, education, and small-business productivity has to live somewhere. Harford County can choose a safer, locally accountable model and capture the upside.
Schools and services
Large private investment can broaden the tax base for schools, public safety, roads, and county services without adding families to classrooms or commuters to every peak-hour road.
Work people can see
The buildout supports years of construction work, apprenticeship pathways, operations jobs, maintenance work, and local supplier demand.
A future industry here
AI capacity supports defense, health care, agriculture, manufacturing, logistics, education, and the everyday businesses that will use these tools.
Local control
The proposed path lets the County define the standards now, instead of waiting for statewide rules or watching investment leave for other markets.
The safeguards are not side promises. They are the project.
Mountain Branch has been shaped around the hard questions residents ask first: power, water, noise, setbacks, traffic, emergency response, environmental protection, and who is accountable if ownership changes. The site scale matters: 275 acres allows meaningful buffers, staged development, and room to separate homes from major equipment.
Self-supplied power
The campus is proposed around on-site, behind-the-meter generation as the primary operating model, with limited utility interaction for approved reliability, startup, construction, and protection needs.
Solid oxide fuel-cell platform
The proposed power model uses modular fuel-cell technology that converts pipeline natural gas into electricity through an electrochemical process rather than a traditional combustion turbine or diesel-generator model. Air and carbon impacts remain subject to final permitting and professional review.
Low-water cooling
Closed-loop, air-cooled, or similar low-water systems are proposed for routine operations, reducing reliance on public water for process cooling.
Residential buffers
The 275-acre site can support meaningful residential setbacks, dedicated equipment setbacks, screening, lighting controls, acoustic modeling, and enforceable operating limits.
Phased campus scale
The planning concept contemplates an initial large-scale power architecture in the 800+ MW range, with a long-term campus potential approaching 1 GW as phasing, approvals, and tenant requirements are finalized.
Environmental review
Stormwater, wetlands, forest conservation, floodplain, air, Chesapeake Bay, traffic, and fire-safety requirements remain subject to applicable county, state, and federal review.
Not a blank check. A conditional path with enforceable rules.
The proposed special-development framework should make the County's approval conditional, measurable, and enforceable. The approval should not say "trust us." It should say "prove it, document it, bind it, and give the County enforcement tools."
A civic contract, not a donation.
The proposed CBA framework should convert public promises into local commitments that are documented before final approval, reported over time, and binding on future owners where legally available. That is how Harford County prevents a future buyer from inheriting the zoning without inheriting the obligations.
Local workforce
Maryland prevailing wage, local hiring targets, apprenticeship utilization, and workforce reporting tied to construction and operations.
Education pipeline
AI readiness, trades pathways, and technical programs that connect Harford County students and workers to the jobs created on-site.
First responders
Support for fire, EMS, training, emergency planning, and site-specific response coordination before operations begin.
Farmland and land stewardship
Farmland preservation, environmental monitoring, stormwater safeguards, and conservation commitments tied to the approval package, including a 5-to-1 farmland-preservation framework if adopted in the final CBA.
Community investment
Annual or milestone-based community contributions directed to agreed local priorities, with public reporting.
Successor accountability
The benefits should be structured so future owners cannot quietly walk away from the commitments that made approval possible.
The benefits are large because the project is large. The rules should be just as serious.
The estimates below should be treated as planning figures pending final engineering, phasing, tax, and entitlement review. The important point is not a single headline number. It is the scale of what Harford County can govern, capture, and require before final approval.
Heavy infrastructure first
Early phases focus on site work, power architecture, utility interfaces, roads, security, stormwater, and the physical platform needed to support advanced computing.
Campus capacity over time
The planning concept scales in phases, with an initial large-scale power target and long-term campus potential approaching 1 GW as approvals and demand mature.
Tenant equipment follows
The largest long-term investment comes as computing halls, tenant systems, chips, networking, operations, and repeated technology refresh cycles are deployed over time.
Planning source note: labor-hour figures are based on craft-hour benchmarks, trade-percentage assumptions, and project engineering due-diligence inputs. Final public numbers should be reconciled to the master fact sheet before launch.
A pause does not protect residents unless it produces better rules.
A moratorium by itself
- -Creates no water standard.
- -Creates no power standard.
- -Creates no recorded community benefits.
- -Creates no tax base, apprenticeships, or public-safety funding.
A special-development framework
- +Sets the conditions before final approval.
- +Requires professional verification of major claims.
- +Lets the County enforce setbacks, noise, water, power, and environmental safeguards.
- +Locks in a community benefits pathway for local workers, schools, and public safety.
Approve standards. Require safeguards. Capture the opportunity.
Mountain Branch is asking Harford County to consider a better model: one that treats AI infrastructure as serious civic infrastructure, with enforceable rules and community benefits attached.
