Ultra-low-emission　technology　has　been　extensively　applicated　in　China＇s　thermal　power　industry.　Accompanyed　with　it,　the　emission　level　of　China＇s　thermal　power　industry　has　undergone　significant　changes.　Therefore,　inventory　emission　factors　and　emissions　in　China＇s　thermal　power　industry　is　unable　to　reflect　the　current　situation　of　thermal　power　pollutant　emissions.　In　this　paper,　a　bottom-up　method　was　proposed　to　establish　China＇s　thermal　power　industry　emissions,　which　was　based　on　the　data　of　continuous　emission　monitoring　systems　(CEMS)　for　thermal　power,　environmental　statistics　and　the　data　of　pollutant　emission　permits.　Compared　with　traditional　way,　the　proposed　new　method　was　characterized　by　a　more　comprehensive　consideration　of　the　ultra-low-tech　thermal　power　industry,　the　actual　concentration　of　emissions　and　activity　levels　and　other　comprehensive　factors.　It　is　a　concrete　example.　And　accroding　to　the　proposed　the　bottom-up　method,　this　paper　calculated　high　resolution　power　emission　inventory　for　China　based　on　CEMS　in　2015　(HPEC).　The　results　showed　that　in　2015,　the　average　emission　concentration　values　of　SO2,　NOx　and　particulate　matter　in　different　provinces　are　7.88~208.57,　40.33~238.20　and　5.86~53.93mg/m3,　respectively.　Beijing　and　Shanghai　had　reached　ultra-low　emission　requirements　as　a　whole.　In　most　provinces,　the　average　concentrations　values　of　SO2　and　NOx　online　monitoring　less　than　the　average　implementation　of　emission　permits　standards.　The　average　emission　factors　of　SO2,　NOx　and　particulate　matter　(PM)　for　China＇s　thermal　power　plants　were　0.667,　0.764,　0.162g/kg　of　coal　for　coal-fired　power　plants,　respectively.　The　emission　performance　values　of　CO,　VOCs,　SO2,　NOx,　PM10,　PM2.5　were　1.06,　0.03,　0.32,　0.39,　0.08,　0.06g/(kW∙h),　respectively.　The　emissions　of　that　in　2015　were　4038.7,　107.3,　1229.4,　1466.8,　287.2,　228.0kt/a,　respectively.　©　2018,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
