Research Findings: Performing Laundry at Night May Alter Power Consumption Patterns

Adjusting Household Energy Use for a Greener Future

German households possess a hidden treasure that could play a crucial role in unlocking the energy transition conundrum: flexible electricity consumption. A study by Eon Energy and the Research Institute for Energy Economics (FfE) reveals that private homes could potentially shift up to 15.6 terawatt-hours of electricity use during peak hours, a figure that could nearly double to 30.9 terawatt-hours by 2030. The regions with the highest potential for this flexibility are Bavaria, Baden-Württemberg, and Rhineland-Palatinate.

Nighttime Chores for a Sustainable Tomorrow

The challenge lies in the fact that the generation of wind and solar energy relies heavily on weather and time of day, while electricity demand peaks in the morning and late afternoon to early evening. Adopting flexible electricity consumption means moving energy-intensive tasks to off-peak hours, such as late evenings or nights. The study examines three household appliances with the highest electricity consumption: washing machines, dishwashers, and tumble dryers, in addition to electric vehicles, home storage systems, and heat pumps.

"Flexibility allows us to shift our energy consumption to times when energy is cheaper or when we have enough renewable energy in the system," explained Filip Thon, CEO of Eon Energy Germany. This potential of 15.6 terawatt-hours is comparable to the combined electricity consumption of cities like Munich and Warsaw, as per Thon.

Electric Cars, Heat Pumps, and Home Storage Systems: Flexible Friends

Germany currently has about 40.4 million washing machines, 32.6 million dishwashers, and 22.1 million tumble dryers in households. By 2030, the authors anticipate that these figures will remain relatively steady. However, the expected increase in the adoption of electric vehicles, energy transition technology, and household solutions like heat pumps, home storage systems, and electric cars will boost the "flexpotential" by 2030, to approximately 30.9 terawatt-hours, according to the study. By 2030, the authors predict around 3.6 million installed heat pumps, nearly 5.9 million electric cars, and 4.7 million home storage systems.

To incentivize households to adjust their electricity consumption habits and thereby enjoy financial benefits, the study proposes time-of-use electricity tariffs. However, widespread deployment of digital smart meters, which has been slow in Germany, is crucial for this. In a YouGov survey of 3,600 consumers, over two-thirds expressed their readiness to shift large chunks of their electricity consumption to off-peak hours if it meant financial gains.

Tapping into the Potential: Overcoming Challenges

The Role of Regulations

Current regulations often do not fully acknowledge the benefits of flexible energy systems. Promoting policies that support flexible market operations for storage systems and simplifying grid connection conditions could encourage wider adoption.

Educating the Public and Promoting Participation

Raising public awareness about the benefits of flexible consumption and actively involving people in the transition process can boost engagement. Incentives for households that adopt flexible energy practices can also stimulate interest.

By addressing these challenges and harnessing the potential of flexible household energy consumption, Germany can move closer to its goal of an 80% renewable electricity mix by 2030, ensuring a more sustainable and stable energy system.

Flexible electricity consumption in German households can play a significant role in achieving a greener future by 2030. By shifting energy-intensive tasks to off-peak hours through washing machines, dishwashers, and tumble dryers, electric vehicles, and heat pumps, Germany can reduce the strain on the grid during peak periods, making it easier to integrate renewable energy sources. Flexibility can lead to cost savings of up to eight billion euros annually in system costs. To encourage households to adopt these practices, incentives, time-of-use electricity tariffs, and widespread deployment of smart meters should be considered.
