Here's a simplified version of how it works: ERCOT tells the transmission operators they need to take X megawatts off the grid.

以下是其工作原理的简化版本：ERCOT 告诉输电运营商他们需要从电网中减少 X 兆瓦电量。

ERCOT continued ordering additional load to be shed from the system trying to keep up with both the rising demand from the cold weather and the quickly failing power plants.

ERCOT 继续下令减少系统的额外负载，以满足寒冷天气带来的不断增长的需求和快速故障的发电厂。

As the evening continued, though, it became clear to ERCOT and utilities that the amount of electricity available on the grid may not be able to continue to meet the demand.

然而，随着夜晚的继续，ERCOT 和公用事业公司清楚地意识到，电网上的可用电量可能无法继续满足需求。
