In case you haven’t heard, electricity demand is shooting through the roof.
After a couple of decades of flattened usage due to more efficient lightbulbs, appliances, and factories, the growing adoption of EVs and remote work, not to mention the explosion in new data centers for compute-intensive applications such as AI, demand for electricity has skyrocketed the past couple years according to a new report in the New York Times. In fact, forecasters estimate that peak demand in the summer will grow by 38,000 megawatts nationwide in the next five years, which is akin to adding another California to an already overburdened grid.

The Times report does a good job highlighting how EVs and higher usage air conditioning in homes are two of the biggest culprits for reversing the trend, but largely omits any discussion of another potential big driver of electricity usage in the future: induction cooking.
And from the looks of it, induction could significantly impact the overall electricity usage of a family home. While it’s more energy efficient in general, a household switching from gas to electric induction cooking will use more electricity. How much? According to some sources, an hour of induction cooking will use between 1.4 kW and 2 kW per day. That compares with about 2.5 kW per day in charging for the typical EV.
So, not quite as much as EV, but still enough to translate to a significant draw on the grid once we’re talking tens of millions of induction stoves. All of which begs the question, will the grid be ready?
It’s something that’s definitely on the mind of some in the appliance world. One appliance executive recently told me that grid readiness is one of the microenvironment variables they are factoring in when evaluating their own induction cooktop strategy. Add to that various local restrictions around gas cooking (and pushback against said restrictions), and the calculation as to how much they push electric appliances gets somewhat nuanced depending on a given market‘s grid readiness and regulatory environment.
My own guess is that while we’re finally seeing induction making inroads in the US, the adoption isn’t moving at such a rate that it will make matters significantly worse than other factors, such as EV and data center growth. In fact, it’s because those other reasons have grabbed the attention of those responsible for forecasting and building out our electricity infrastructure that the industry will more than likely be ready for when we hit tens and even hundreds of millions of induction cooktops in homes.
