抽水蓄能电力产品的分类、社会属性与成本分摊

Category,Social Attributes and Cost Allocation of Electric Power Products of the Pumped-Storage Power Plant

抽水蓄能电站的产品基本上可分成高峰电能和辅助服务两大类。高峰电能相当于电力系统内的私人产品,可以直接卖给电力消费者,当具备相关条件时,其价格可由市场竞争决定。辅助服务相当于电力系统内的公共产品,不能直接卖给电力消费者,只能由系统操作机构(相当于电力系统的管理者)统一收购;其购买成本,也只能通过向电网用户的普遍加价(相当于电力系统的消费税征收)予以收回。

The electric power products of the pumped-storage power plant can be divided into two categories： power energy in peak hours and ancillary service. The electricity energy in peak hours can be regarded as a private product in the power system, which can be directly sold to consumers and whose price is decided by market competition when the related conditions are made ready. The ancillary service is equivalent to the public product within the power system, and it cannot be sbld to electricity consumers directly. Insteadly, it is purchased, on bulk basis, by the ISO, namely the single buyer （an organization playing the governmental role in the power system） and its cost can be recovered by universally raising the electricity tariffs for all consumers, which is equivalent to consumption taxes levied for the power system.
