How can home energy management contribute to the energy transition? What do the systems we need for this transition look like? And when is such a system open, fair and inclusive? Commissioned by the Rijksdienst voor Ondernemend Nederland and Top Sector Energy, Waag is developing a Public Stack for home energy management systems: Home Energy Management Systems (HEMS).

The transition to renewable and low-carbon energy sources is accompanied by technological developments and challenges. One of these challenges is the predicted increase in electricity consumption, due to increasing electric driving and heating. The main challenge in this is the 'mismatch' between energy supply and demand. Electricity from renewable sources is produced when the sun shines and the wind blows, but not necessarily when we consume electricity. A Home Energy Management System could help to resolve this mismatch in energy supply and demand.

A Home Energy Management System is connected to the smart meter, which monitors what the energy consumption of appliances in the home is. It can then control these appliances based on information from outside the home and based on preferences. With HEMS, it becomes possible to better match energy supply and consumption. These systems are not yet far developed or widespread. This is the time to safeguard public values in the development of this technology.

In this exploration, we work with a wide range of parties during workshops. We explore questions like 'what revenue models are becoming possible for energy management systems?' and 'what do we as a society want to achieve with HEMS for whom?'. Do we want some parties to make a lot of money? Or is the main aim that we save energy and make it more sustainable, and what does the road towards that aim look like?
