Mount Tom Coal in Holyoke

Power produced = 146 mw
http://www.firstlightpower.com/generation/mttom.asp

2002 Annual electrical generation = 915,318 MWhr
2002 Annual CO2 emissions = 961,342 metric tons x 1.1 = 1,057,476 tons
CO2 emissions = 1,057,476 tons x 2000 lbs / 915,318 MWhr = 2,310 lbs/ MWhr

Estimated rate using 2002 annual generation of 915,318 MWhrs

NOx = 2,296 tons x 2000 lbs / 915,318 MWhr = 5 lbs/ MWhr
SO2 = 7,373 tons x 2000 lbs / 915,318 MWhr = 16 lbs/ MWhr
PM 2.5 = 43 x 2000 lbs / 915,318 MWhr = 0.09 lbs/ MWhr
PM 10 = 95 x 2000 lbs / 915,318 MWhr = 0.20 lbs/ MWhr
VOC’s = 14 x 2000 lbs / 915,318 MWhr = 0.03 lbs/ MWhr

New emissions controls are supposed to effect a 95% SOx reduction

SO2 = 16 lbs/ MWhr x .05 = 0.8 lbs per MWhr

and other new Requirements by 2008 are:

NOx emitted = 1.5 lbs/ MWhr
SO2 emitted = 3.0 lbs/ MWhr
CO2 for existing power plants = 1,800 lbs / MWhr

Thus approximate final Mt Tom data =
CO2 = 1,800 lbs per MWhr
NOx = 1.5 lbs per MWhr
SO2 = 0.8 lbs per MWhr
PM 2.5 = 0.09 lbs per MWhr
PM 10 = 0.20 lbs per MWhr
VOC’s = 0.03 lbs per MWhr

(Proposed) Pioneer Biomass in Greenfield

http://www.pioneerrenewableenergy.com/?page_id=279

Power produced = 47 mw
Expected Annual electrical generation = 378,782 MWhr per year
Expected CO2 emissions according to ENF = 489,300 tons
(Note: this number appears erroneous. The similar Russell plant claims it would release over 600,000 tons which is more in line with expectations based on calculations.)

According to the proponents understated CO2 numbers:
CO2 emissions = 489,300 tons x 2000 lbs / 378,782 MWhr = 2,583 lbs/ MWhr

According to expected carbon releases:
CO2 emissions = 600,000 tons x 2000 lbs / 378,782 MWhr = 3,168 lbs/ MWhr
Note: Average CO2 for new power plants is about 760 lbs/MWhr

Other Pollutants:
ENF Table 2-2 Boiler Stack Emissions

NOx = 164 tons per year x 2000 lbs / 378,782 MWhr = 0.87 lbs/ MWhr
SO2 = 68 tons per year x 2000 lbs / 378,782 MWhr = 0.36 lbs/ MWhr
PM 2.5 = 52 tons per year x 2000 lbs / 378,782 MWhr = 0.27 lbs/ MWhr
PM 10 = 52 tons per year x 2000 lbs / 378,782 MWhr = 0.27 lbs/ MWhr
VOC’s = 27 tons per year x 2000 lbs / 378,782 MWhr = 0.14 lbs/ MWhr

Thus final Pioneer data =

CO2 = 2,583-3,168 lbs per MWhr
NOx = 0.87 lbs per MWhr
SO2 = 0.36 lbs per MWhr
PM 2.5 = 0.27 lbs per MWhr
PM 10 = 0.27 lbs per MWhr
VOC’s = 0.14 lbs per MWhr
