Genesee Generating station is coal fired plant , located near Warburg, Alberta,Canada .

There are five Genesee Generating Station Units :- Genesee 1, 2,3,4 &5 ( Capital Power ,2016).The owner of Genesee 1&2 is Capital Power Corporation, G3 is joint venture between TransAlta and Capital Power. Capital Power operates the merchant plant, both parties are independently dispatch and market their share of the electrical output through the Alberta Power Pool (TransAlta Corporation,2017).The proposed Genesee 4 & 5 combined cycle natural gas-fired generation facility is a mutual project between Capital Power and ENMAX (Capital Power,2016).                                                         Design / Operating featuresFigure 1: Coal fired power station layout .

The Genesee Mine is a 7,378 Ha surface strip mine located in Central Alberta north of the Town of Warburg and close to Edmonton.  The mine operates two active pits and supplies sub-bituminous coal to the three units at the Genesee Generating Station which are owned by Capital Power and TransAlta Utilities and operated by Capital Power (Westmoreland Coal Company, 2018).Environmental Performance                                                                                                                                                          Genesee generating plant emits oxides of nitrogen (NOx), sulphur dioxide (SO2), carbon monoxide (CO), particulate matter smaller than 2.5 ?m (PM2.5), mercury (Hg) and ammonia (NH3) (Stantec consulting ltd,2013).NOX are produced in most combustion processes and are almost entirely made up of nitric oxide (NO) and nitrogen dioxide (NO2). Together, they are often referred to as NOX. The oxidation of these compounds and their combination with water in atmosphere form nitric acid as a component of acid rain (Stantecconsulting ltd, 2013).

Sulphur dioxide further oxide & produce sulphuric acid when combine with water, sulphuric acid is also component of acid rain (Stantec consulting ltd, 2013).Carbon monoxide produce cardiovascular symptom in individual.Mercury is harmful to both human and wildlife. Ammonia can affect body if it contact the skin of eye and if it is inhaled (Stantec consulting ltd, 2013).Carbon dioxide emission rate is 953.92 kg/ MWh, its total emission is 8,873,134.45.

Sulphur dioxide emission rate is 1.79 kg/MWh and total emission is 16,680.24. Nitrogen oxide emission is 1.47 kg/MWhand total is 13,635.01 (North American Power Plant, 2016).                                                                              Table3:                                                                                                                                                Stack InformationNameHeight (m)Diameter (m)Exit Velocity (m/s)Exit Temperature (°C)GGS Stack 1-21217.

SO2 emissions is 57% below Alberta standards .It meets US EPA emissions standards. NOx emissions is 20% reduction, meets Alberta standards. Particulate Matter emissions: >99.8% capture efficiency.(KindzierskiW,2007).In G3 plant ,$90 million investment in clean air technologies cuts nitrogen oxide emissions in half and stops 99.9 per cent of particulates from entering the atmosphere (TransAltaCorporation ,2017).
