The Arizona Department of Environmental Quality is taking comment until Jan. 19 on an air permit that would allow Arizona Public Service to install and operate a microgrid, consisting of 40 diesel-fired internal combustion engines in Yuma.
The microgrid will provide back up power to a U.S. Marine Corps Air Station during grid outages. APS may also operate the generators for supplying power to the grid for peak shaving. It is called the APS MCAS-Yuma facility.
The facility would consist of forty 685-kW internal combustion engines (ICEs). The ICEs would be the Volvo TWD1673GE model.
