???? 據阿納多盧新聞5月27日消息稱，美國能源情報署(EIA)周二表示，由于天然氣價格上漲和來自可再生能源的競爭加劇，2021年美國天然氣發電量自2017年以來首次出現同比下降7％。

????在美國，天然氣發電正面臨來自可再生能源發電的日益激烈的競爭，因為最近風力和太陽能發電廠的裝機容量達到了創紀錄的水平。

????該機構的《小時電網監測》數據顯示，在2021年前4個月，美國48個州的天然氣發電平均每天3394吉瓦時(GWh)。

????總體而言，由于冬季天氣變冷，該國在這一時期的發電量比2020年增長了6.6%。

????數據顯示，從2020年5月到2021年2月，美國新增的風能和太陽能綜合凈發電能力增加了15%，達到22.5吉瓦(GW)。

????該機構表示，自2020年4月以來，美國天然氣價格上漲，原因是與上一個冬季供暖季(從2020年10月至2021年3月)相比，天然氣產量減少，冬季供暖需求增加。

????美國天然氣價格上漲，使得天然氣發電相對于燃煤發電的競爭力下降，促使天然氣燃料轉向煤炭燃料。

????EIA稱，與2020年同期相比，2021年前四個月該國的燃煤發電量增長了近40％，占總發電量的23％。

????報告稱：“我們預計天然氣發電的下降將持續到2022年。在5月份的短期能源展望中，我們預計2021年天然氣發電量將下降9.1%，2022年將進一步下降0.7%?！?/p>

????US natural gas generation declines 7% in 2021

????US natural gas generation in 2021 saw its first year-over-year decline since 2017 of 7% due to higher natural gas prices and increased competition from renewables, the Energy Information Administration (EIA) said on Tuesday.

????Natural gas-fired generation has been facing increased competition from renewable generation in the US because of recent record-high capacity additions to wind and solar power plants.

????In the first four months of 2021, natural gas-fired generation in the Lower 48 states averaged 3,394 gigawatt-hours (GWh) per day, data from the agency’s Hourly Electric Grid Monitor showed.

????Overall, the country’s electricity generation during the period increased 6.6% compared with 2020 because of colder winter weather.

????Between May 2020 and February 2021, an increase of 15% to 22.5 gigawatts (GW) of combined net wind and solar electric generating capacity additions came online in the US, according to the data.

????US natural gas prices have risen since April 2020 because of lower natural gas production and higher winter heating demand compared with the previous winter heating season that ran from October 2020 to March 2021, the agency said.

????Higher US natural gas prices have made natural gas-fired generation relatively less competitive compared with coal-fired generation, prompting natural gas-to-coal fuel switching.

????Coal-fired generation has increased nearly 40% in the country during the first four months of 2021 compared with the same period in 2020 and accounts for 23% of total generation, the EIA said.

????“We expect declines in natural gas-fired generation to continue through 2022. In May’s Short-Term Energy Outlook, we forecast natural gas-fired generation will decline 9.1% in 2021 and a further 0.7% in 2022,” it said.
