資料簡介

由于廉價天然氣和可再生能源的激烈競爭,煤炭在美國電力結構中的市場份額正以前所未有的速度下降。在過去三年中,約30gw的煤炭產能已經退役,同期煤炭發(fā)電量下降了13%。美國煤電的經濟性是無法回避的:新的煤炭產能并不具有競爭力,而在未來幾年內,現有煤炭的運營成本將低于新天然氣和可再生能源的成本水平,這將是一個例外。

Coal’s market share in the US power mix is being diminished at an unprecedented rate due to fierce competition from cheap gas and renewables. Around 30 GW of coal capacity has been retired over the last three years, with coal generation declining by 13% over the same period. The economics of US coal power could not be starker: new coal capacity is not remotely competitive, while in the next few years it will be the exception rather than the rule for the operating cost of existing coal to be lower than the levelized cost of new gas and renewables.
