Mine electricity demand vs. Generator capacity

Mines consume a tremendous amount of electricity in order to crush rock - so much so that mines usually build their own power plants or partner with utilities to make sure they have the capacity to meet their demand. Here demand for some of Alaska's largest existing and proposed mines and power plants. Proposed projects are faded relative to active projects.

Data for this figure was cobbled together from many sources, including a state level meeting on power supply for large mines, and a study proposing the merger of Alaska railbelt utilities.  We assumed that the mine power estimates we have are for average power needs rather than peak needs, though this wasn't specified.  Because very large mines typically operate continuously, it's likely their peak power demands are similar to their average demands.
