Governor Gavin Newsom says some energy users and utilities will be allowed to tap backup power sources.

州长加文·纽森说，一些能源用户和公用事业公司将被允许使用备用电源。

Plus, there can be a connection for a nine-volt battery, as a backup power source.

此外，还可以连接九伏电池作为备用电源。

Both the primary and backup power sources failed so the pumps and cooling systems for the spent fuel pools couldn't run leaving the water to heat up.

主电源和备用电源都发生故障，因此乏燃料池的泵和冷却系统无法运行，导致水升温。
