For example, it recently won an order to provide a 2.2 megawatt-hour battery, the size of a shipping container, for use in tests to back up a Chinese coal-fired power station.

例如，它最近获得了一个订单，为中国的一个火力发电厂提供一个2.2兆瓦时，集装箱大小的电池，进行备份测试。

Prices have fallen from around $60 per megawatt-hour last summer to $20-30 this summer. They are strongly tied to the prices of natural gas and coal, which have both fallen too.

电价从去年夏季每兆瓦约60美元下跌至今夏的20—30美元，紧随天然气和煤的跌价而下跌。

Similarly, solar thermal energy--which harnesses the heat of the sun to generate steam-powered turbines--consumes more than 2, 600 liters of water per megawatt hour, 200 liters more than coal-powered generation needs to produce the same energy.
