The Federal Energy Regulatory Commission on Aug. 12 granted qualifying facility (QF) status to Mosaic Fertilizer LLC for a 14.8-MW power project in Louisiana.
The so-called Uncle Sam (2014 Small Power Production Facility) is a 14.8-MW (net) waste heat facility located in St. James Parish County, La. The energy input to the facility is reject/waste heat recovered from the exothermic reactions involved in Mosaic’s sulfuric acid manufacturing processes.
The sulfuric acid plants convert the waste heat into superheated steam for supply to a steam turbine-generator set that will produce electricity. The facility will also include associated auxiliaries, including feed and condensate pumps, water circulation pumps, etc.
Under section 292.203(a) of the commission’s regulations, qualifying small power production facility must comply with the size and fuel use criteria specified in section 292.204 of the commission’s regulations. Mosaic’s facility does not exceed the 80 MW power production capacity size requirement; and the sole energy source of the facility is waste heat, a permissible energy source, FERC noted. Fossil fuel will not be used by the facility for any purpose. Therefore, Mosaic satisfies the size and fuel use requirements for certification as a small power production QF.
