董秘您好！请问三门核电站预计什么时候投产呢？核电利润和火电利润相比，在当前煤价的情况下，核电利润率会高出多少，核电主要成本来自哪儿？预计三门核电投产每年会为公司带来多大的利润？请问贵公司最近开设的电力服务子公司是否已经开始运营？十分期待贵公司具体详尽的回复，谢谢。
三门(men)核(he)电(dian)(dian)(dian)是(shi)(shi)中(zhong)(zhong)国核(he)电(dian)(dian)(dian)的控股子公(gong)司，中(zhong)(zhong)国核(he)电(dian)(dian)(dian)也(ye)是(shi)(shi)上市公(gong)司，因(yin)此涉及(ji)到中(zhong)(zhong)国核(he)电(dian)(dian)(dian)或(huo)是(shi)(shi)三门(men)核(he)电(dian)(dian)(dian)的有关情况，向中(zhong)(zhong)国核(he)电(dian)(dian)(dian)咨询更为妥当。根据(ju)2016年报，中(zhong)(zhong)国核(he)电(dian)(dian)(dian)的毛利(li)率是(shi)(shi)40%，浙(zhe)能(neng)电(dian)(dian)(dian)力的毛利(li)率是(shi)(shi)22%，从中(zhong)(zhong)您就可以(yi)看出核(he)电(dian)(dian)(dian)和火电(dian)(dian)(dian)的差距。如(ru)果以(yi)公(gong)司成立(li)为标志(zhi)，能(neng)源服务(wu)公(gong)司应该算是(shi)(shi)运营了；如(ru)果以(yi)业务(wu)开展为标志(zhi)，目前(qian)还处于起步摸索阶(jie)段。
