Connecting Communities.Building Data Centers Right.
As your Ally, we are committed to bringing communities, local governments, and the data center industry together through open, honest and respectful dialogue. We consider every stakeholder’s perspective by connecting trusted resources from leading industry associations through a singular platform. We also aim to help communities access accurate information, informative battle cards to drive responsible data center development while protecting the local community.

MY ALLY BRIEF
Start with what brings you here.
Choose your perspective to receive three relevant tools and a guided option to turn those next steps into a practical brief.
01 / KEY POINTS
One building. Five community questions.
The honest answer is rarely a single number. Design, climate, operating conditions, and local agreements all matter.
02 / COMPARISON LAB
Change the assumptions.
See what changes.
These calculators explain relationships—not a specific project. Replace every starting value with locally sourced data before making a public claim.
SITE / COMMUNITY COMPATIBILITY
How much separation and landscape restoration are planned?
Distance from homes is a starting point—not a universal safety rule. A credible siting review identifies the closest receptor, terrain, transmission routes, emergency access, and future land use.
Assessment weighting: Distance to the nearest home contributes 70% of the score. The native tree or plant replacement target contributes 30%.
DISTANCE-PRIORITIZED SITE ASSESSMENT
Good site-selection starting point
Ask the developer: What is the nearest home today and under the future land-use plan, and where will the mature native canopy be measured?
03 / THE EVIDENCE GUIDE
A number without context is just a talking point.
Use the same six-part label on every public claim. It makes comparisons fairer and source updates much easier later.
ANATOMY OF A CREDIBLE CLAIM
In Loudoun County, data centers added$16 billion in real-property value in2024, bringing the total to $41 billion, according to Loudoun County’s FY2026 budget materials.
Why this claim works
It is positive without being vague. It names the place, the type of value, the one-year increase, the resulting total, the period, and the government source. It does not turn assessed property value into jobs, cash in hand, or a guarantee of lower taxes.
What to ask next: How much of that assessed value becomes recurring local revenue, how volatile is the equipment tax base, and which services or reserves receive the money?

TAKE THIS TO THE MEETING
Six questions that get past the headline.
Each question includes three likely answer types so you can recognize a strong commitment, a partial answer, or a warning sign.
01What is the maximum—not just average—electric demand?
+
A phased MW schedule, maximum demand, expected annual load factor, utility agreement, and who pays for required upgrades.
A single average MW number with no seasonal peak, phase date, or interconnection milestone.
Power is available and the utility will handle it—without a filed study, cost allocation, or maximum demand.
02Which cooling and heat-rejection systems will operate at each phase?
+
Named equipment by phase, closed-loop boundaries, peak-day mode, backup mode, and annual potable and reclaimed-water estimates.
The design is closed loop—without explaining whether cooling towers or other evaporative heat rejection still consume water.
The technology is proprietary, so no operating mode or water information can be provided.
03Is reported water use withdrawal, consumption, potable water, or all three?
+
Separate average and peak values for withdrawal, consumption, discharge, potable water, and reclaimed water.
One annual water number with no source, peak-day demand, or distinction between withdrawal and consumption.
The system recirculates water, therefore the project uses no water.
04Where will sound be measured, at what times, and in which units?
+
Property-line and residential receptor results in dBA and dBC, octave-band and tonal analysis, nighttime limits, and generator testing.
A modeled daytime dBA result at the property line only, with no low-frequency or emergency-operation case.
The equipment meets manufacturer ratings, so neighborhood measurements are unnecessary.
05Which community benefits are written, funded, and enforceable?
+
Dollar amounts, recipients, delivery dates, local maintenance and vendor targets, workforce programs, and public annual reporting.
A general promise to support schools and local hiring without a budget, owner, or schedule.
Benefits will be decided after approval and reported only at the operator’s discretion.
06Who publishes performance after the building begins operating?
+
A named owner publishes annual power, water, sound, jobs, tax, and outreach results, with a correction process and independent verification.
The operator will share selected sustainability metrics but has no fixed reporting date or local contact.
Operational data will remain confidential and there is no post-construction reporting commitment.
Add these six questions to your project brief.
They will remain attached to My Ally Brief with your saved lab scenario and selected evidence cards.
