Energy art appreciation corner with Colin Murchie – pv magazine USA


“Sometimes you get to do great shit at work.”

The brilliant and singular Colin Murchie, Senior Director of Business Development at EVgo, provides an overview of the United States, analyzed by utility territories.


I did this as part of my day-to-day work at EVgo, where we are still developing a large national network of fast chargers for electric vehicles.

The underlying data used to create the map is public; this is the “Retail Service Territories” layer and service published by the Ministry of Homeland Security as part of its data at the level of the foundation of the infrastructure of the homeland.

The data was synthesized by the Oak Ridge National Laboratory, Los Alamos National Laboratory, Idaho National Laboratory, National Geospatial-Intelligence Agency, and the Homeland Security Infrastructure Program team.

I generated the styles and visualizations in ArcGIS Online for our internal GIS tool. Colors are generated randomly on each launch, primarily using ESRI’s default color palettes.

When we use it internally, there are also different filters, boundary and opacity treatments, especially to better represent the boundaries of municipal and cooperative public services. And of course the labels!

There are funny stories here. You can see all of Nebraska covered in these co-ops that * sort of * follow the county lines until you take a closer look, or see the Kentucky Utility Co. plotting the topography there. Of course, knowing if a utility territory is really a polygon is not a simple matter of mapping – they are not really “shapes” legally …

The results are often very beautiful, which I think makes people use it more.
