Since Units 1 & 2 are slated for decommission by 2022, we suggest that you consider using your existing infrastructure, but redesigning the coal burning facilities. With all the property at your disposal, you could easily get a good return on investing in either Solar &/or Wind Power. Not only would you be lowering the carbon footprint, but you would become heroes world wide.
Why is this important?
Coal has been in the spotlight, as contributing to climate change. In Montana, as elsewhere, many jobs are affected by the global economics that have led to the closing down of Colstrip Units 1 & 2 by 2022. Those jobs could be saved by redesigning the coal burning industry into Solar &/or Wind projects
