The Takeaway

While using smart tech to shift heating and cooling loads can save power grids millions, the actual savings for an individual household in this North European study were less than €1 per square meter per year. This massive gap between collective benefit and individual reward makes the technology's widespread adoption economically irrational for regular people.

From the abstract

Widespread residential demand response (DR) could potentially help alleviate the growing pressure on power grids caused by increasing shares of variable renewable energy, but knowledge of its energy market impacts is still lacking. This study modelled different penetrations of residential electric heating and cooling DR in Finland as a part of a 2025 North European energy system for weather years spanning 2011–2016 using the Backbone energy system optimisation framework. The impacts of two DR st
