The nuclear plant generates several thousand megawatt-hours per year.
Tips
usage
兆 = mega- (million), 瓦特 = watt (transliteration of James Watt's name). Often shortened to 兆瓦 (zhàowǎ). For gigawatt use 吉瓦 (jíwǎ); for kilowatt use 千瓦 (qiānwǎ).
memory
瓦特 is the 'Watt' of James Watt — the steam engine pioneer's surname became the SI unit name and stayed that way in Chinese. Same pattern for 牛顿 (Newton), 焦耳 (Joule), 赫兹 (Hertz).
