Arapahoe Combustion Turbine Project: FAQ
- Where is Arapahoe Combustion Turbine Project?
- In Denver County, Colorado (CO). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.

- Who owns Arapahoe Combustion Turbine Project?

This page shows only what EIA files, and does not assert a corporate structure it cannot see.
