6 lessons for surfacing hidden capacity in commercial buildings

This one is about big commercial buildings, not houses, but it's worth knowing about since it shows where the grid is headed. Utilities are struggling to add new power capacity fast enough, so companies are turning to office buildings, schools, and healthcare facilities to find "hidden" flexibility in how they use energy. The idea: automatically adjust things like heating and cooling systems in large buildings during times when the grid is under strain, instead of building expensive new power plants.

Two companies, McKinstry and Edo, described how this works. Software connects to a building's existing management systems, pulls in data, and automates small load adjustments without much effort from building staff. In one example, a college campus discovered snow-melt gutter heaters had been running all summer, wasting energy, once building data was centralized and reviewed. Building owners who take part can get payments for providing this flexibility, plus early warning about equipment problems before they turn into costly repairs.

None of this applies directly to a single-family home, since it depends on the kind of building management systems only large commercial properties have. But it points to a broader trend: utilities increasingly want existing buildings to flex their energy use during peak demand rather than always adding new infrastructure. Homeowners may see a smaller-scale version of this idea already, through utility programs that adjust smart thermostats or water heaters during high-demand periods in exchange for bill credits.
