Grid bottlenecks are nothing new

Every time technology starts demanding a lot of power, people say the grid can't handle it. Right now it's EVs and AI data centers.

Before that it was air conditioning. And before that it was refrigerators and all kinds of electric appliances people now barely even think about.

In 1930, only 8% of American homes had a refrigerator. By 1950, 80% did. That is a massive jump in demand from machines that ran all the time, on a grid that was way smaller than the one we have now.

Same thing with washing machines. Same thing with electric irons. Same thing later with AC. In the late 1950s, hardly anyone had air conditioning at home. By 2020, 88% of households did.

And every time, people asked some version of the same question: how is the grid supposed to handle all this?

The answer was simple. The grid grew to meet the new demand.

Between 1902 and 1930, US electricity generation grew 20x. Between 1945 and 1965, generation capacity grew 4x. Household electricity use kept climbing too. The system expanded because demand was rising and the country built around it.

So when people say the grid can't handle what's coming, they're talking like the grid is some finished product. It's not. It never was. The grid has always changed to match demand.

What is different now is not that the challenge is bigger than anything we have seen before. What is different is that we have made it a lot harder to build. Transmission lines can take 7 to 10 years to permit. Around 2,600 GW of proposed generation is stuck in interconnection queues, and only a small share ever gets built. Transformer lead times have gone from months to years.

So yes, the constraint is real. But it is not that the grid cannot grow. It is that we have slowed down the process of growing it. That is a big difference.

The grid has handled wave after wave of new demand for more than a hundred years. It can do it again. The real question is whether we are going to make it easier to build what is needed. That is the part I wish more people talked about.
