Utilities are regulated, and customers pay fixed rates regardless of wholesale market changes. This means people do not see higher prices when power is scarce, such as during extreme cold. Without price signals, demand stays flat even when the grid is under stress. Devices like smart thermostats could adjust usage automatically. But without financial reasons to cut back, they do nothing. Even widespread use of automation cannot create demand response if users feel no cost from scarcity. The result is that only utility decisions reduce load during emergencies. Customer actions do not help. To change this, retail prices must reflect real-time wholesale prices. This would give users a reason to reduce usage when demand is high. Only price-based incentives can connect customer actions with grid-wide stress.

This return is capped, but it still drives companies to focus on building things like substations. They earn more from these builds than from flexible technologies that could improve grid resilience. The rules have created a system where profits depend on spending money on hardware. There is little financial gain in using smart systems or local energy sources to reduce strain on the grid. As a result, companies underinvest in these options. Power failures affect whole regions and consumers, but the costs are not borne by the companies. When blackouts happen in extreme weather, the blame does not hit the bottom line enough to change behavior. Regulators can enforce reliability standards but often accept infrastructure spending as proof of compliance. True responsiveness to demand shifts is not required. Past failures in Texas and California show that simple rules do not work under the current profit model. The real problem is not lack of oversight. It is that the profit motive is tied to construction, not performance. Until earnings are separated from building new equipment, incentives for smarter grid use will fail.

As a result, companies have little reason to invest in smart devices or tools that reduce power demand. Technologies like smart thermostats could ease winter power strain, but they don't expand the customer base or infrastructure. Since returns come from building assets, not saving energy, innovation is delayed. Even when demand control is possible, companies avoid it. It threatens their revenue model.

But only if people agree to join the program. During the 2021 Texas power crisis, most smart thermostats were not used. That was because enrollment was optional. Even with many devices installed, grid operators could not control enough of them. The problem is a lack of automatic enrollment. Without it, control over power use stays fragmented. Each household decides separately whether to take part. This means that total energy savings fall far short when power is scarce. Technology alone cannot fix this. More devices do not help if they are not linked to a shared control system. The real limit is not how many people own smart thermostats. It is whether operators can access them quickly in an emergency. So, widespread use of smart thermostats does not ensure reliable power cuts. Most users must still opt in. And during a crisis, that takes too long. Only if enrollment were mandatory could the grid get the fast response it needs. Otherwise, devices remain underused.
