石油圈中國石化新聞網訊 據Gas Processing News網站1月22日休斯敦報道，美國能源信息署（EIA）的2018年1月短期能源展望報告預測，天然氣在今后至少兩年時間里仍將是美國發電的主要能源來源。 燃氣發電廠供應的總電量比例預計將從2017年的32%分別增加到2018年的平均33%和2019年的平均34%。EIA預計數十年來一直是發電主要原料的煤炭的發電量比例將從2017年的30%持平到2018年并減少到2019年的平均28%。 為了應對燃料成本的變化以及可再生能源技術的發展，用于發電的的能源結構將繼續改變。自2015年以來，用于發電的天然氣成本一般在每百萬英國熱量單位3.5美元或者更少，預計2019年將保持在這個水平左右。 EIA預計，未來兩年內，天然氣發電成本將對燃煤發電成本保持相對競爭力。 李峻 編譯自 Gas Processing News 原文如下： EIA forecasts natural gas to remain primary energy source for electricity generation EIA’s January 2018 Short-Term Energy Outlook (STEO) forecasts that natural gas will remain the primary source of U.S. electricity generation for at least the next two years. The share of total electricity supplied by natural gas-fired power plants is expected to average 33% in 2018 and 34% in 2019, up from 32% in 2017. EIA expects the share of generation from coal, which had been the predominant electricity generation fuel for decades, to average 30% in 2018 and 28% in 2019, compared with 30% in 2017. The mix of energy sources used for producing electricity generation continues to shift in response to changes in fuel costs and the development of renewable energy technologies. Since 2015, the cost of natural gas delivered to electric generators has generally averaged $3.50 per MMBtu or less, and it is expected to remain near this level through 2019. EIA expects the cost of natural gas for electricity generation to remain relatively competitive with coal-fired electricity over the next two years.
