Arizona Public Service permits microgrid, supported by 40 engines

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.
