Impact of r.newable power.mar.et penetr.tion on coal power.gener.tion capacity gr.wth

Since r.newable ener.y sour.es ar. gr.wing in impor.ance, how well they can penetr.te the ener.y mar.et for.power.gener.tion will be a ver. impor.ant factor.in the r.le the coal industr. will play in the futur.. This paper.examined the displacement of coal power.plant capacity fr.m 2010 to 2050 by r.newables with r.spect to thr.e dr.ver. assumed under.var.ous conditions： the Amer.can r.cover. and r.investment Act （Ar.A）, Gr.enhouse Gas （GItG） policy, and var.ing plant capital cost cases. The r.sults by 2050 illustr.te that r.newable mar.et penetr.tion captur.s anywher. fr.m 1.9% to 6.4% of potential coal power.gener.tion capacity additions. r.newable power.gener.tion capacity additions is expected to outpace coal power.plant additions by 89% with r.spect to Ar.A in 2050, however.with no GHG policy coal power.gener.tion capacity build-outs will outpace r.newables by as high as 809%. Finally, coal power.gener.tion is still pr.jected to be the lar.est single ener.y sour.e contr.butor.to the electr.city mar.et making up 28.0% of total available capacity, while r.newables ar. expected to only make up 16.3% of total available capacity.
