Question

请帮忙翻译以下一段话

It also plans to build coal-using power plants that can generate 10.74 million kilowatts of electricity, with an objective to launch their operation by late 2020, while constructing renewable power plants producing a combined 4.56 million kilowatts of electricity.
With the additional power generating capacity, the ministry predicted that it can raise the country's electricity reserve rate to 22 percent by 2027. Despite operation halts caused by either aging parts or maintenance works, the reserve rate could remain at around 15 percent, it noted.
请不要借助翻译工具！谢谢

Answer 1

It also plans to build coal-using power plants that can generate 10.74 million kilowatts of electricity, with an objective to launch their operation by late 2020, while constructing renewable power plants producing a combined 4.56 million kilowatts of electricity.
它还计划在建立能够生产456万千万时电量的可再生能源发电厂的同时，建立能够生产1074万千万时电量的煤炭发电厂，并计划在2020年下半年投入运营。
With the additional power generating capacity, the ministry predicted that it can raise the country's electricity reserve rate to 22 percent by 2027. Despite operation halts caused by either aging parts or maintenance works, the reserve rate could remain at around 15 percent, it noted
有这些额外的发电能力，······部（这里只有ministry，你要看一下，这是什么部）预计到2027年可以将我国的电力储备率提升至22%。尽管会因为零件老化或维护工作导致运营中止，它指出，但是电力储备率仍然可以保持在大约15%左右。

Answer 2

它（应该是指一个文件）规划建设若干燃煤电厂，发电容量为10.74百万千瓦，预计目标是它们在2020年投入运行。同时建设可再生能源电厂，做发电量为4.56百万千瓦。

有了这些增加的发电容量，该部预测到2027年国家电力储备比例将上升为22%。尽管运行会由于部件老化或维护工作二时有中断，但储备比例仍将保持在15%左右。它指出。

Answer 3

政府部门还计划建造一座能发出1074万千瓦时的电量的火电站，并计划于2020年下半年投产使用，同时建造一座可产生456万千瓦时可再生电力的发电站。
随着额外的电力产生的容余，相关部门预计到2027年其可以提高国家电力22%的储备率，尽管由于设备的老化或设备的保养而造成的设备的中止运行，相应部门指出那时国家的电力储备率依旧可达到大约15%的水平。
