Much easier to put in line heaters on the water lines that froze in the nukes and coal plants, and space heaters on the gas valves, because those were the primary cause of the failure of the Texas grid last year. The wind turbines in Montana and the Dakotas did not fail, and it was much colder for much longer there, so there are obviously was to winter proof them. And the gas valves did not freeze up in Minnesota, so obviously there is no reason for them freezing up in Texas.
There were
failures among all means of power production, and all should be winterized.
B. Key Findings and Causes
From February 8 through 20, in the Event Area, a total of 1,045 individual generating units—58 percent natural gas-fired, 27 percent wind, six percent coal, two percent solar, seven percent other fuels, and less than one percent nuclear—experienced 4,124 outages, derates or failures to start. Of those outages, derates, and failures to start, 75 percent were caused by either freezing issues (44.2 percent) or fuel issues (31.4 percent), as shown in Figure 3, below.
Natural gas fuel supply issues caused the majority, 87 percent, of the 31.4 percent of outages and derates due to fuel issues, and caused 27.3 percent of all outages, derates and failures to start during the Event.In addition to the 44.2 percent of outages and derates caused by freezing issues, the 21 percent caused by “mechanical/electrical issues” also indicated a relationship with the cold temperatures—as temperatures decreased, the number of generating units outaged or derated due to mechanical/electrical issues increased. Figure 4, below depicts the locations of the generation outages, derates and failures to start during the Event.
