Their paper titled Performance of distributed energy resources in three low energy dwellings during the UK lock down period examines household energy use and performance of low carbon technologies in Yorkshire, during the Covid-19 lockdown. The research study is part of a five-year €4.2 million EU funded project - Zero Plus on zero energy settlements.
The research found that the use of smart home batteries coupled with rooftop solar panels, resulted in over 95% reduced average direct grid consumption during peak hours. The estimated cost benefit to homeowners using smart energy systems in the study ranged from annual savings of between £260 and £438.
The study explored the change in daily energy use and performance of distributed energy resources (DERs) such as electro-chemical batteries, during the Covid-19 lockdown period from 23 March 2020 to 31 May 2020. Three houses in an eco-development in York, were occupied continuously by families during that time. They had identical heating systems (district heating), rooftop solar panels and home batteries (14kWh). The energy use, generation and charge-discharge of the batteries were monitored every five minutes using remote sensors.
