Real, public data from sources like the EIA, EPA, USGS, and OpenStreetMap, with every number traced back to where it came from.
Data centers, transmission lines, substations, and solar farms are reshaping neighborhoods across America. GridHalo puts them on one map and explains what each one means for your power, water, air, and jobs.
Big energy and data projects are usually decided in hearings most residents never hear about, with data spread across dozens of government agencies. GridHalo brings that public information together so anyone can see what is being built near them and speak up while it still matters.
Real, public data from sources like the EIA, EPA, USGS, and OpenStreetMap, with every number traced back to where it came from.
The Halo Score turns complicated impact data into a single, explainable rating for each project's effect on its community.
Follow projects, track public-comment and hearing dates, and discuss what is happening with your neighbors.
Everything lives in the sidebar of the app. Here is what each tab does.
Browse every tracked project on an interactive map. Filter by data centers, transmission, substations, or renewables, and click any marker for details.
Enter your address or just a ZIP code and choose a radius to see which projects are near you and how far away they are.
See how each project scores on water, emissions, jobs, and nearby schools and hospitals, and which factors pushed the score up or down.
Ask the AI advisor questions like "How much power do these data centers use?" and get answers grounded in the project data.
Post concerns, questions, or support about a project, tag topics like noise, water, or traffic, and reply to your neighbors.
Follow the projects you care about and keep their public-comment deadlines and hearing dates in one place.
