In addition to the production of SNG, the plant also produces high purity carbon dioxide, which is distributed through a pipeline to end users in Saskatchewan, Canada (Apache Canada at the Midale field and Cenovus Energy at the Weyburn field, until that asset was sold to Whitecap Resources in 2017) for enhanced oil recovery operations. Operational profitability of the GPSP is affected by the market price of natural gas, with which SNG competes. In response, an anhydrous ammonia synthesis unit was added to the process train at the plant in the 1990s, diversifying the plant's product line away from synthetic fuels (SNG), with a substantial capacity to produce anhydrous ammonia, a feedstock for fertilizer production. The plant can shift production to higher value products, depending on fluctuating market conditions. Kemper County Energy Facility Lignite coal gasification to produce electricity Southern Company Services/Mississippi Power started construction on a new IGCC plant located in Kemper County, Mississippi in December 2010. Construction for the Kemper project is 75% complete as of January 2013. Start of commercial operations for the plant is scheduled for 2016, in which the plant will convert 12,000 tons of local Mississippi low-rank coal per day (large reserves of 4 billion tons of mineable lignite are located near the plant) to produce 582 MW (net) of electricity. The new plant will utilize KBR's TRIG™ gasifier technology, suitable for utilization of the local lignite resources; two of the gasifiers will operate in air-blown mode at the Kemper County plant. TRIG™ and related systems for gasification of low-rank coal had been developed by KBR and Southern Company in conjunction with DOE at the Power Systems Development Facility (PSDF) in Wilsonville, Alabama, which comprised an engineering-scale demonstration of TRIG™ and associated critical subsystems. This provided the engineering and operational basis for the full-scale plant now being constructed in Kemper County. The plant will capture and sequester 65% of the CO2 it produces through enhanced oil recovery. Emissions controls will remove over 99% SO2 and P25, at least 90% Hg, and limit NOx emissions to less than 0.07 lb/million Btu. The Kemper County IGCC project is estimated to cost $4.7 billion, but the Kemper plant will be the cheapest plant to operate once it's up and running. Mississippi Power has received a $270 million grant from the Department of Energy and $412 million in investment tax credits approved by the IRS through the National
